Joji Sherman- 12 years until Doomsday?
In class, we have been learning about the topic of climate change. I can safely guess that at least ninety percent of you have not been sleeping under a rock the past few months, so you probably have heard the environmental debates intensifying in the political landscape. Notably, there have been talks of a “Green New Deal,” a massive plan to implement numerous massive changes in the US, from making energy completely renewable to investing in a national high-speed rail system, all within the next 10 years. Of course, it failed in the end, but that is a topic for somewhere else.
Given the magnitude of such changes, why only 10 years? Many of you likely already know the answer. The
United Nations IPCC- the Intergovernmental Panel on Climate Change- released a report last year that
humanity can regulate the extent of global warmth to 1.5°C if we cut global carbon dioxide emissions by 45%
before 2030- that is, within the next 12 years. Some believe that if we fail to meet this target, as US politician
AOC put it, “the world is going to end.” Given how much the US releases, cutting our emissions is imperative
in reaching this goal.
The difference between 1.5 and 2 degrees Celsius seems minimal, but analyses show that that half degree
distance could be a do-or-die situation. It is the difference between the desolation of 70-90% of our coral reefs
versus over 99% of those that exist now. It divides a sea-ice-free summer in the Arctic only happening once
every 100 years from a sea-ice-free summer once per decade. It is what could stop an area of permafrost the
size of Mexico from melting. In the end, some of the damage has already been done. Severe tropical storms are
bound to increase, ecological decline is bound to happen, economies and industries will suffer, and human
health will be adversely affected. However, preventing this extra half-degree of warmth could help mitigate
the effects in a major way.
the effects in a major way.
This “12-year model” has sparked boundless amounts controversy, and is interpreted by many to be wildly
inaccurate. Some models indicate that the critical tipping point for reversing our impacts is a threat that lies in
a different time, with dates such as 2060 marking the crucial point. Others believe that viewing the 12-year
frame as a hard line rather than a suggestion is blatantly wrong, instead taking the approach of “every decision
matters, and the impacts will gradually get worse overtime the less we act.” In the end, the thought of a
“doomsday” or an “apocalypse” has constantly been changing since the idea first was thought of, and will
change until the day it happens. However, the concept lingering in the back of our minds does go a mile or two
in encouraging us to act and make a change for the better.
Some questions for the end:
How realistic do you think the UN’s hard deadlines on carbon emission reductions in relation to environmental impacts are?
Do you believe that the spread of the “doomsday” idea does more harm than good?
What can humanity as a whole or you as an individual do to help curb global climate change?
