Climate Change Explained Simply

This is a simple explanation of Climate Change, based on an article in the New York Times.

                                          

All this could take centuries, but something like the sudden collapse of agriculture would 

trigger immediate chaos in society.

Best case is we get our act together and begin to rapidly bring emission levels down; meanwhile, 

Earth turns out to be less sensitive to greenhouse gases than we currently believe, plants and

animals adapt quickly,
and major technological breakthroughs help society limit emissions

and adjust to climate change.

But, these are all the opposite of what we’re actually seeing, so the only thing in our 

control is to limit emissions using all available tools and best behaviors currently at our 

disposal.

Worst case, the collapse of food production causes spiraling prices and -- as our capitalist 

utopia breaks down -- billions starve as our world gets violent and messy real quick--kind 

of like a zombie apocalypse, but with extreme hunger spreading chaos instead. So, yeah, 

still just like a zombie apocalypse. This would be coupled with the melting of the Antarctic 

ice sheet, leading to rapidly rising seas that would force us to abandon many of our 

greatest cities and all of the social and scientific progress that we were making within 

them. Adding insult to injury is the fact that many of the emissions were emitted while 

building these now abandoned, underwater metropolises.

If emissions continue unchecked, we’re looking at a total rise of between 80 to 160 feet, 

which would occur if all the ice in the polls melted. So the oceans will rise, the real 

question is how fast?

Scientists only have Earth’s history to base their predictions on, which suggests 

that the rate has occasionally hit 1 foot per decade...so we’ll have to adapt to an 

altered coastline sooner or later, but probably much sooner than later. Because...

Computer forecasts only give us a range of future possibilities, the most important evidence 

comes from the study of past climate conditions which clearly show that every time the amount 

of carbon dioxide in the air rises, the Earth warms up, ice melts, and the ocean rises.

What’s important to remember here is that we are in uncharted territory--humans are 

pumping carbon dioxide into the air far faster than nature ever has before us.

Scientists have been publishing strong evidence that warming is making drought and heat waves 

more frequent, causing heavier rainstorms, and more severe coastal flooding. But while 

the Internet has made us all more aware of weather disasters in distant countries, it’s 

hard to prove these are all directly made worse by climate change, although they probably 

are.

Canada and Russia both have vast, frozen lands, and could see some economic benefits from 

a warmer climate. Putin and the Russians, therefore, have been reluctant to make ambitious 

climate commitments. But expect that to change as these countries realize they will be swamped 

by millions of refugees from less fortunate nations.

Libertarians and other political conservatives do not like the policies proposed to fight 

climate change and have chosen to try and block them by actively undermining the science.

This effort has been funded by the oil and coal industry, who favor making money above 

all else.

As more resources are devoted to solving the problem, our chances at big technological 

breakthroughs are improving, but we still should be spending about three-times as much 

money as we currently are on these efforts according to several in-depth reports.

You can reduce your carbon footprint by doing things like plugging leaks in your home insulation, 

installing a smart thermostat, taking public transit, taking less airplane trips, buying 

an electric car, and putting solar panels on your roof. A big one is eating less meat. 

But what’s really needed is for you to speak up and exercise your rights as a citizen, 

because strong, collective action through state and national policies is how we’ll 

make the most impact. 

Considering that we’ve been ignoring scientists’ warnings since the 80’s to limit emissions, 

we’re pretty late in the game. But we’ve finally reached a moment where nearly every 

country in the world agrees this is a huge problem, and seem ready to commit to taking 

at least some kind of action. Leading corporations will continue to make bold promises to do 

their part, low-emission technologies will improve, and many states and cities will go 

much further than any goals set by their national governments. The United States, the world’s 

biggest economy, is finally starting to move aggressively, and China, the world’s largest 

emitter, is beginning to recognize that it needs to do the same, as many of its megacities 

cities will be underwater if the seas rise too high. But it’s up to us, the ordinary 

citizens, to continue demanding our political leaders tackle climate change, the hardest 

problem that humanity has ever faced.
