Cordless Drills And Cordless Power Tools For Craftsmen And Do It Yourself Home improvers

The Cordless Drill.

Can there be any doubt the cordless drill has revolutionized the job of any skilled laborer or craftsmen? Literally, for some skilled tradesmen the cordless drill has knocked off hours from each and every day for him or her, and made them far more productive than they once were within the hours they did work.

Of course electric drills have been around for a fair amount of time, however, the cordless drill provides mobility far beyond the plug into the wall socket electric drills, and greater safety besides. With a cordless drill, the peril of a nicked electrical cord, or getting the cord tangled in something or another are gone, and besides, rolling out and rolling back up long extension cords can be very tedious – especially for jobs when the drill is needed, but the greater power provided by one hundred and twenty volts isn’t so necessary.

So far as drills go, they aren’t going anywhere – according to Wikipedia humanity has been using some sort of something or another to drill holes for various purposes for at least thirty five hundred years, and I suspect that, in fact, using some sort of tool or rock or something to drill a hole has been with humanity as a constant bit of working or building of various and sundry things for far longer still.
What Are The Uses Of A Cordless Drill?

Not to bore anyone to tears, but the truth of the matter is that most often in my two major lines of skilled labor or work, the cordless drill isn’t used so much for the drilling of holes as it is for the fastening or unfastening of things to or from a solid surface. In other words, cordless drills get used a lot as cordless screwdrivers, or cordless nut-drivers.

Especially in the HVAC industry, everything is fastened together with either quarter inch hex head screws, or five sixteenths inch hex head screws, but because these screws can often be very very tight or rather rusted and old, the power of the cordless drill is very much needed in many cases, as this prevents the use of a pair of channel lock pliers in conjunction with a nut-driver tool.

This Fall and Winter, I’m working as an electrician, and the electrician is more one to be screwing fixtures together with traditional Philips head or flat head screws, or even actually drilling holes into things to insert a screw, as the situation might call for.

It doesn’t much matter if you use a cordless drill in your mode of employment or not, in this day and age of things forever being fastened together by screws of various and sundry shapes and sizes, it is practically an essential tool to have on hand at the homestead, whether you be male, female, old or young. Practical applications within the home or on a job involving a cordless drill are for all intents and practical purposes more than anyone could ever get around to naming or listing.

The History Of Cordless Drills.

According to Wikipedia cordless drills have been in the use of humankind for at least thirty five hundred years. I suspect that number is nowhere near big enough, as the history of the world is far far vaster and greater than it is presented to us dumbed down Americans in our corporation controlled indoctrination books.

Please keep in mind that what a cordless drill could look like or be made from greatly surpass the sort of thing one generally has flash in their mind when the term cordless drill, comes to pass through there.

The Wikipedia article on drills mentions the Harappans and Egyptians, but obviously what is shown above as a hand powered and very cordless drill is not what we’re truly concerning ourselves with here, as of course, we’re talking about battery powered cordless drills in the modern homestead and the modern workforce. What is shown below is also very much NOT the things used by cultures from the distant past.

I’m told via this link here, that for all intents and practical purposes the technology behind what now constitutes the battery powered cordless drill originated with the German corporation known as Bosch. Despite all that, the biggest three names in cordless drills, from my own experience, seem to be those of DeWalt, Makita, and Milwaukee.

The reality is that while most craftsmen I know use either a DeWalt or a Milwaukee cordless drill, some of the older guys refer to all cordless drills of any brand as “Makitas.”

Makita Cordless Drills

The Makita cordless drill company has been around since 1915 when it was established in Japan, in 1970 they established a US subsidiary, and their stock is actively traded publicly all over the world. Makita has established itself firmly in the power tools market and as I’d stated before, some people, older craftsmen and contractors, will simply refer to a cordless drill as a “Makita.”

Sadly for the value of the product and the consumer too, the year 1993 saw the Makita corporation setting up factories in China, but of course that matters not too much to someone simply looking for a cordless drill.

Makita is still “Japan’s largest manufacturer of power tools,” despite them not being made in Japan much anymore. Of course we see how multi national corporations work. Makita makes a huge array of power tools for all industries, but the general opinion I am hearing out in the field and on the job is that their products do not stand as firmly in the minds of craftsmen here in the USA as do those by either DeWalt or Milwaukee.

Now one shouldn’t think that the three brands I’m going to discuss here are the only ones out there making good cordless drills, that would be very far from the reality, and in fact, these three brands I am going to discuss are very recognizable, and very desired by all the local thieves wherever you live.

So far as myself and the work that I do, no single drill will truly suffice for the simple reason that the larger 18 volt drills are too big to carry in a tool pouch all day, they’ll roll out of the thing, fall, and get damaged. Often times if I’m simply opening up a condenser or hanging a light fixture, then the smaller 7.2 volt drill will more than suffice, and those CAN typically be fitted into a tool bag or tool pouch safely without fear of the thing falling out.

The big 18 volt drills, of course, have more settings and more capability, and when the drilling of holes through dense metals is the job, then those are certainly the drills to have.
Milwaukee Cordless Drills

There is a very nice page of history concerning Milwaukee and their products that I recommend as good reading for any or all interested right here. Suffice it to say that as much as I like DeWalt drills, I like Milwaukee better, and I believe I’ve found the Milwaukee cordless drill I want to purchase.

By and large the craftsmen I deal with on a weekly basis prefer Milwaukee to Makita, but in no tangible way do many, or a significant enough number of craftsmen in skilled trades that I do know and speak with consider DeWalt drills either better or worse than Milwaukee drills, saws, so forth and so on – products.

I’d be rather amiss here were I to fail to mention Porter Cable Brand cordless drills, and in fact I’ve been using one particular Porter Cable brand drill semi frequently lately on the various and sundry jobs I’m blessed to be a part of.

The DeWalt Ultimate Cordless Tool Set.

The complete DeWalt cordless tool combo set is a bit imposing on the price end of things, but is a truly terrific investment for a craftsman on the move with varied jobs that need doing. This set, of course, greatly exceeds merely the cordless drill, the cordless combination kit includes the following:

This is a pretty extensive power tool set all with use of the same 18 volt rechargeable batteries – there are lesser or most appropriately arranged with the tools one might more or not need for less amounts of money, but for most intents and practical purposes the skill saw, the sawzall, and the cordless drill and flashlight are essentials for the commercial and residential crafts-person alike.

Literally, nearly every man with a skilled labor job wants the DeWalt set, but besides all of that, most around here do own a DeWalt 18 volt Lithium Ion rechargeable battery powered cordless DeWalt drill, and so they should, unless they just happen to own another brand’s comparable one.

Most cordless drills of the now standard 18 volt variety have reasonably similar specifications, the specifications for the standard DeWalt model, however, are as follows:

There are many many models from all manufacturers of various and sundry voltages – all nowadays are rechargeable with lithium ion batteries – but none of them are expected to replace entirely the time honored plug in 120 volt drill, as sometimes a person just needs more power and for longer periods of time.

DeWalt Power Tools – Drill Screwdriver and Jig Saw Reviewed

My Personal Reviews and Recommendations

DeWalt power tools are very popular with many good reviews and favoured by many DIY enthusiasts and professionals alike.

I for one in recent years have come to know and trust these tools and accessories as a mark of quality and, with few exceptions, when replacing an old power tool of my own will put this Make at the top of my list.

In this review article I make my recommendations for a choice selection of these power tools and accessories based on my own knowledge and experiences.

The two I currently own and frequently use is an 18v cordless drill come screwdriver and a durable jig saw which runs from the mains, but having seen the power and reliability of today’s batteries would next time buy a cordless version.

Choosing the Right Drill
Corded Vs Cordless

One of the most fundamental and most used of all electric power tools is the drill. From my early days of DIY many years ago I’ve always owned and used a good electric hammer drill with a plug that works from the mains. That’s fine as long as the electric is on and if working outside you have an extension cable long enough. The problems comes if you don’t have access to the mains power and carting an extension cable around as well as the drill at best is an inconvenience and at times can be a real pain; especially when you’re lugging a load of other tools with you.

Both my friends who are into DIY had cordless drills, one a retired builder with a Cordless DeWalt and another DIY enthusiast the proud owner of a Makita and when I helped them with their DIY projects the advantages of cordless drills was so blatantly obvious; so much so that it was obvious that I needed to upgrade to cordless.

Good electric drills are not cheap so I spent ages researching the DeWalt, Makita and other cordless drills before making an informed decision. Although there are a lot of good ‘Makes’ of Cordless Power Drills, after carefully comparing all the specs., and reviews (especially independent user reviews) on balance I ultimately decided to opt for the DeWalt as my favoured choice.

DeWalt 18 Volt Cordless Power Drill
Also Makes an Excellent Screwdriver

Having decided on DeWalt my next decision to make was which DeWalt Model I should go for as there are plenty of DeWalt Models to choose from and often the differences between models can be quite minor. In this respect the first choice was to ensure any cordless drill I opted for included the ‘hammer drill’ option; anyone who has tried drilling through brickwork with a hammer drill will know what I mean. Then my main decision was whether to opt for the 12 volt or 18 volt cordless drill. At the time the 18 volt versions were considerably more expensive than their 12 volt counterparts so it needed careful consideration. On comparing the specifications and reviews the 18 volt version became a clear choice in that extra power means extra torque which can be especially useful for large and stubborn screws and sometimes when drilling through tough material.

So on this bases I opted for and purchased the 18 volt cordless drill which has since served me well, it has given me excellence performance with no problems or issues and has exceeded all my expectations; particularly in battery performance and the versatility of the screw driving facility.

First the batteries, I’m no expert on batteries but the older NiCad battery types my friends have (having older drills) do slowly drain when not in use and to prolong their life need a complete discharge from time to time and do last longer if fully discharged before recharging. Whereas the new Li-ion is brilliant, it doesn’t discharge when not in use so when I leave the drill stored away over winter I can confidently pick it up in the spring for my first DIY project of the year knowing that it has power. It also means the spare battery already charged will work at a moment’s notice when needed; and when I do replace the battery the one I’ve just taken out of the drill goes straight on charge and within the hour will be fully charged for when next needed. And unlike the old batteries these batteries don’t need to be fully discharged, they can be safely topped up at any time if need be.

As regards screw driving this cordless drill has saved me hours. Previously I did all my screws by hand, which can be laborious, hard work and very time consuming; even with a ratchet screwdriver. I was given a rechargeable battery operated screwdriver years ago, with the battery built into the handle, but the battery discharged quickly, needed to be charged before each use and wasn’t very powerful; so I invariably ended up doing it by hand anyway. However, with this DeWalt drill, just a quick twist of the chuck to change bits e.g. from drill bit for pilot hole to screwdriver bit and you’re ready to roll. There is a switch at the top to change from drill to screwdriver setting (which is a good habit to get into) but if you forget it doesn’t really matter it will still act as a screwdriver. And for reversing e.g. to undo a screw, you just press the black button on the side; so the whole operation is incredibly easy.

I do have a good ‘Stanley’ hand ratchet screwdriver which I keep in my toolbox and on occasions will use it for quick jobs e.g. the odd screw or two, and it uses the same screwdriver bits as the cordless drill (which is handy) but in the main I mostly use the DeWalt for most screw jobs.

What Do The Numbers On My Key Mean?

Types of Numbers on Keys

All kinds of numbers, letters and symbols appear on the heads of keys. Some are stamped into the metal while others are embossed during the molding process. This article is about the information contained in these numbers and letters and chiefly deals with the following categories:

Bitting Numbers
Key Blank Model Numbers
Key Numbers Within a Master Key System
Key Code Numbers

Anatomy of a Key

In order to get a basic understanding of numbers and letters that appear on keys it is necessary to know the parts that make up a key. Below is an illustrating showing the various regions and what they are called:

Bow (or Head) – serves as the handle that one uses to grasp and turn the key. Here is where most key numbers appear.
Stop – on most keys located next to the bow, it keeps the key from going into the lock too far. Distances measured starting at the stop locate the cuts of the key. On certain kinds of keys the stop is located at the tip of the key instead of the bow, but it serves the same purposes.
Blade – the business end of the key. Here is where the cuts that correspond to the key’s bitting are located.
Cuts – to make a standard pin tumbler key, one cuts away material to specific depths to accommodate the length of a pin. These depths are numbered according to their size in thousandths of an inch. For example, a number one (1) cut may be .213″ (two hundred thirteen thousandths of an inch) on a particular brand of key. Listed, these depth numbers comprise the bitting of the key. See the section about bitting later in this article.
Tip – the opposite end of the key from the bow. Used to identify the order of a bitting. For example, one could say the bitting on this key is written “bow to tip”.

If a key has no cuts, it is not called a key. It is called a “blank.”

Which Cordless Power Drill Do You Need? Can My Flowchart Assist You To Judge?

I created a wee flowchart to aid me to decide among the heap of power drills and drill/drivers possible.
I acquire more than 50 drill/drivers a year for my business. On checking my purchase invoices I got a bit of a shock at how much I paid my current supplier and also how frequently I was renewing them!
I decided to set up a flowchart to help me to decide both which drill or drill driver I needed and also the best place to obtain the drill.
Where to get was an easy decision. The Internet. Amazon. My regular supplier was charging me approximately 50% more than the Amazon price and their only reason was that I got next day delivery and that I had 30 days to pay. To be fair, you don’t wait longer than a small number days for Amazon’s free delivery and the benefit of 30 days credit certainly was not worth the 50% premium! Needless to say, I no longer buy any drills from my old supplier!
So what did I ask of my flowchart? Not much if truth be told.

1. I required a heavy duty 18V drill/driver that could get by with heavy duty tasks without burning out. I just wouldn’t buy anything inferior.
2. I likewise desired a 1/2 inch chuck so that it could live with with larger drill bits and sockets.
3. I also needed it to be extremely lightweight so as not to cause stress (RSI).
4. A lithium-ion battery gave me the lightweight and likewise gave me the quick charge facility I also needed.
5. 2 Batteries. Even swift charge batteries need a stand-in while they are charging!
6. Robust build excellency. I require my drills to last and last and last.
7. Hammer action for drilling into brick and blockwork.

So which drill/driver did my flowchart lead me to? The DEWALT DCD775KL 1/2-Inch 18-Volt Cordless Compact Lithium-Ion Hammer-Drill Kit

It ticked all of my boxes:

Heavy duty dual speed 18v motor.
1/2 inch chuck
Lightweight. At only 4.1lbs, this is be one of the lightest 18v cordless drill/drivers on the market!
Lithium ion battery and charger with spare battery included. These batteries fully charge within 30 minutes and reach 80% of full charge within the first 10 minutes!
It’s a Dewalt! They last and last and Last!
Variable speed hammer action for any eventuality.
(It also has a wee LED light to shine on your work)

And where to buy it? Amazon. And right now they are currently offering an immense 40% off making Amazon most likely the cheapest place on the internet right now to buy the DEWALT DCD775KL 1/2-Inch 18-Volt Cordless Compact Lithium-Ion Hammer-Drill Kit

I have now acquired quite a few. And are they performing? They absolutely are! And I don’t replace them nearly as often as the alternative models I was once buying. Proof of the pudding, I have even paid for one for home!

The History Of Pneumatic Equipment

The discovery of pneumatics and its inclusion in industrial applications are counted among the most important contributions to modern technology. There are a great many applications that make use of pneumatic equipment or are pneumatically powered in today’s world, yet most people are unaware of the contributions that pneumatic technology makes towards everyday modern life because pneumatic machinery often functions in the background. Other inventions along the way have facilitated the incorporation of pneumatic technology into industrial systems, such as Pisco tube fittings, without which it would be difficult to attach air hoses to different pieces of pneumatic machinery.

Hand Operated Compressors

The entire idea of pneumatics stems from the idea of using air to do work. In order for the usually unresisting and unsubstantial air to do work, it first needs to be compressed in some way. Today, this is done by modern air compressors that run on electricity or fossil fuels. In olden days, however, there was already a form of air compressor that was manually operated – the hand bellows. Bellows were accordion-like devices that pushed air out a small nozzle at high pressures. Blacksmiths used these devices to pump air into their forge fires to make them burn hotter.

Modern Compressors

It was only in the early 1800s that the first modern air compressor was built that utilized cylinders arranged in succession to compress air. This was the beginning of the development of pneumatic technology and its incorporation into industry. Scientists and inventors did not realize the potential of the air compressor at first, and it was some time before it was put to real use.

Modern Tools

It was only in the late 1800s that the first pneumatic drill was invented, running on compressed air provided by a modern air compressor. People immediately realized the significance of this invention, powerful yet driven only by air, which was a much more efficient source of energy than running the drill with an electric motor.

Modern Applications

There are many modern applications of pneumatic technology that are not even apparent unless you were to conduct a careful study of certain technologies. The engines on a jet plane, for example, make use of pneumatic technology to operate. Another example is the set of tools that you find in every dentist’s office, including the drill that is the instrument that causes great fear in many people still and which runs on pneumatic power. Pneumatic technology remains relatively unknown because most people have been brought up only being taught that machinery runs on fuel-driven motors or electricity. Thus even when a dentist’s drill gives off a telltale hiss of exhaust air, people do not make the deduction that it must be powered by air and is hence a pneumatic tool.

Industrial Applications

Pneumatic components are widely used in factories and assembly lines, as pneumatic technology is clean and efficient. For the best results from your pneumatic equipment, you should use Pisco tube fittings to attach the air hoses in your system to the equipment, thus ensuring that air will not escape from the system and reduce its efficiency.

Repairing Things Made Easy Through Electric Drills

Tools are necessary to be able to perform the task at hand. Each tool serves a certain purpose. One has to know what specific tool is needed so as not to create further damage. Whether it is for building a house or simply repairing certain things, these tools can come in handy.

Houses are prone to repairs and it is but right that the tools needed are available in one’s home so as to make the necessary repairs in time. Basic tools like hammer, saw, and drills are needed in constructing and repairing things at the same time. Construction material companies have made the essential adjustments to cater to the growing demand of people who wish to do certain things on their own like building partitions in the house or repairing an area in one’s home. A lot of DIY (do-it-yourself) tools are available.

A drill is one essential tool that should be present in one’s home. These drills are used to make the necessary holes without creating too much mess on the walls. There are drills that can be operated manually or electrically though in the recent years it was electric drills that have dominated the construction arena.

There are different types of drills depending on where it is needed. Here is a rundown of some of these drills.

Hand Drill – It uses a hand-operated handle to turn the gear to be able to make the desired hole.

Breast Drill – This is basically the same as the hand drill, only larger and it has a plate to apply the needed pressure for a more accurate result.

Push Drill – It uses repetitive pushing motion in making pilot holes.

Electric Rotary Drill – The most common among all the drills that are available in the market today. This can be used for different materials. It has a corded version and a cordless battery operated version as well.

It is not surprising that more people opt to buy the cordless drill. Some of its features include:

· It is much safer because there is no cord attached in the drill therefore one does not have to worry where it needs to be plugged.
· It is lightweight. Because of this, the drill becomes easier to handle and less pressure is needed in supporting the tool.
· Batteries are rechargeable. Through this, batteries can be changed anytime and anywhere as long as there are battery reserves.
· It offers versatility. Because of this feature, hard to reach areas in one’s home can be accessed through the use of the cordless drill.

So, when buying an electric drill for the first time, be sure to incorporate these pointers to be able to make the right choice.

Brutal honesty has found its place

Recently, I took part in a robust IABC Africa panel debate in Cape Town on communicator readiness for 2020. The thing about discussions like these is that if they are facilitated well, they can spark discussion that sets the tone for the entire conference.
Brutal honesty has found its place
©hatza via 123RF
And ignite unbridled dialogue under the steermanship of director of the IABC International executive board, Daniel Munslow, it certainly did, running well over the conference’s tight schedule.

There is no doubt that demands on communicators are changing now more than ever, and panellists Mia Azam, Woolworths financial services senior communications manager, Sappi’s group head of corporate affairs, Andre Oberholzer, and 2016/2017 chairman of the IABC’s International Executive Board, Dianne Chase, all put forward sound arguments for remaining future fit as the needs of businesses evolve.

But to my mind, the more things change, the more they stay the same – with perhaps one small difference: When your audience ‘pays’ you with their time, it has become even more critical now than ever before to get your message across as quickly and efficiently as possible. The future is about communicating real-time decisions rapidly.

The 24-hour news cycle and the lack of historical perspective has made us all dangerously impatient. Rapid technological disruption, the rebalance of world power, and continuing economic uncertainty, all combine to create highly volatile and increasingly complex messages.

Making this powder keg even more unstable is that communicators need to drill through huge volumes of information and translate issues into easy to understand terms. Our interactions need to break through the clutter and present messages that are compellingly succinct.

What is also fast disappearing – at last – are the communication silos of old and, along with them, the tired necessity of having meetings upon meetings which, more often than not, result in nothing at all.

To the Twitter generation, a week feels like an age. A CEO shares the stage today with much younger and often self-taught opinion makers who, for the most part, have developed a knack for getting their message across in news their audience can use.

Simply put, if you’re not on the bus, it will leave you behind at the station. The holy grail of deadline has never been more sacred.

I work with leaders across a range of business sectors and believe that they rarely have had a more challenging time. It’s not enough to be an executive with stellar credentials who is sorely lacking in effective and efficient communication skills.

In order to remain relevant, it is absolutely critical for executives to adopt an agile approach in their communications. It’s all about reducing complex messaging into short and powerful soundbytes.

So, if I had to offer my clients some advice, I would tell them to broaden their circle. They need to find straight shooters who tell them what they need to hear – not what they want to hear.

Brutal honesty has, at last, found a very real and important place.

President Trump could kill the Paris Agreement – but climate action will survive

November 9 will likely become the day that the Paris Agreement died, but not when the goal of limiting warming to 2? slipped out of reach.

President Donald Trump can, and likely will, drop out of the Paris climate agreement. Direct withdrawal will take four years.

But Trump could instead drop out from the overall climate convention under which the agreement operates. That would only take one year and would result in automatic withdrawal from the Paris Agreement.

It would shortcut any hopes that Paris would bind Trump’s hands for some time.

As I’ve argued in my research, a US withdrawal from the Paris Agreement would be its death knell.

A predictable loose cannon

Trump has also promised a range of further destructive international and domestic actions on climate and energy. These include cutting all international climate financing, rescinding energy regulations, reopening federal and offshore areas for coal and oil development and abolishing the clean power plan.

There is some hope that Trump is a loose cannon who may renege on his previous promises. Such hope is ultimately false. Trump has already appointed noted climate denier Myron Ebell as the head of his Environmental Protection Agency transition team.

More importantly, the Republican establishment supports this approach to climate policy. The agreed Republican platform of July rejects the Paris Agreement and calls for it to be submitted to the Senate (where it would be defeated) as well as an end of all funding to the UN climate convention. Their domestic policies are best summarised as “drill, baby, drill!”

It is foolish to believe that Trump would oppose his own party, and many of the voters of the US “rust belt” whose support he relied on, in an attempt to save the Paris Agreement.

Trump may be unpredictable in some regards, but his approach to climate change is not.

Counting the losses

Trump’s climate policy would lead to the US overshooting its already inadequate 2030 climate targets. The US needs additional measures on top of the Clean Power Plan to meet the targets established by Obama.

The US withdrawing from the Paris Agreement, or blatantly missing its climate targets, could be near fatal for a deal which relies on global ambition. The Paris Agreement relies on two things: increasing ambition through peer pressure, and a signal to markets and the public.

Both peer pressure and the signal will be shredded by a rogue, Trump-led United States.

States will be unlikely to feel pressured if the world’s second largest greenhouse emitter is polluting unabated. The effects of US recalcitrance were all too clear in the case of the Kyoto Protocol, which the United States simply refused to ratify. Trust would be undermined and excuses for inaction amplified if the US abandons international efforts again.

Any signal that existed from the framework of Paris would be largely extinguished. Already fossil fuels stocks have surged post-election despite a downturn in the rest of the market. Renewable energy share prices have plummeted. The idea of the signal hinged on broad participation creating investor confidence in international law. US withdrawal and the breaking of commitments will shatter any belief that investors may have had in Paris.

The Paris Agreement sacrificed binding emissions cuts and finance in order to ensure US participation. The few benefits it had were derived from broad participation, including from the United States. Such benefits will be lost by a US dropout.

Paris will likely survive as a structure. Countries will continue with the global show-and-tell, trading unbinding pledges every five years for some time to come. It will go on, but it will cease to be a large source of hope or change.

Opportunities for the future

A Trump presidency will also create opportunities for renewed action internationally.

Trump promises to usher in an age of protectionism, scrapping free trade agreements such as the Trans-Pacific Partnership (TPP) and North American Free Trade Agreement (NAFTA). He has vowed to brand major trading partners such as China as “currency manipulators”.

At the same time nationalism and discontent with free trade have surged in Europe. China has scaled up its domestic renewable energy and climate policies and is looking to formally establish a national emissions trading scheme next year.

Both a protectionist Trump administration that has dropped out of Paris and trends in the European Union and China could bring the idea of climate trade measures back to the table.

The Paris Agreement could be amended to use trade measures against countries who are not part of the deal. Such a move could not be adopted until the next conference in November 2017. Amending the agreement would only require a three-quarters majority vote, but is still unlikely to garner the support to be adopted under the painfully slow and convoluted UN process.

Climate trade measures from the EU and or China are much more likely. The EU may be pushed by Trump’s trade policies towards imposing a carbon price on imports (carbon border tax adjustments) from the US and others. China may consider a similar move. The two could even act in tandem, creating their own bilateral climate club outside of the Paris Agreement. Such material penalties would likely force the US to eventually shift and reengage with international efforts.

Such an outcome seems unlikely for now, particularly in the politically paralysed Europe. But Trump at least opens the opportunity for such change.

The much maligned Trump will supercharge climate civil disobedience in both the US and around the globe.

The world’s best chance of avoiding dangerous global warming are a climate trade war and rampant climate disobedience.

Such actions will be more beneficial for the climate than the current Paris Agreement ever could have been. The incremental and baseless pledge and review of Paris Agreement would have never been enough to trigger the herculean transition needed.

The 2016 US election will almost certainly become the epitaph for the success of the Paris climate agreement. But it does not mean that 2℃ is necessarily out of reach; the future may not depend on the actions of an ageing superpower.
