Good morning, John!
-
So, the United States is pulling out of the Paris Climate...
-
Agreement...
-
Treaty...
-
A - Accord?
-
Protocol?
-
The - I don't -
-
Let's be honest - There's a really good chance that you have a strong opinion on the Paris agreement,
-
... And an EVEN BETTER chance you don't really know what it is.
-
There are too many things to know, so quick timeline...
-
350 million years ago
-
Ancient plants covered the earth, converting the Carbon Dioxide (CO2) in the air into Oxygen(O2)
-
and carbohydrates.
-
These plants then die, and they create massive mats of organic materials that get buried.
-
Those organic materials then hang around under the earth getting heated up and smushed and form
-
energy-dense hydrocarbons, also called "fossil fuels".
-
Notice how cardohydrate and hydrocarbon sound similar.
-
1882
-
(There was a big gap there)
-
Thomas Edison builds the first centralized coal-fired powerplant.
-
We've been using coal for a long time before that, of course
-
but I'm starting here because we have to start somewhere.
-
For the next 100 years, fossil fuels brought tremendous growth and
-
increases in quality life, specifically in Europe and America,
-
where the vast majority of fossil fuels were burned.
-
Decades pass. The benefits of fossil fuels eventually begin to spread
-
and everyone is consuming more and more.
-
It's great, for the most part, except that all that CO2 that was locked up in fossil fuels for
-
billions of years is now being re-released
-
and CO2 is really good at letting visible light pass through it
-
but infrared radiation that gets bounced
-
back up by the earth does not pass right through it.
-
It gets trapped.
-
So the earth's atmosphere and oceans start having more energy in them
-
and that starts to change the climate.
-
And while fossil fuels give us remarkable abilities to do cool and beautiful things
-
and increase the quality of life
-
here on earth, we also
-
rely on a stable climate, for massive farming operations
-
and coastal infrastructure (by which
-
I mean all of the cities that people live in.)
-
Jumping forward again
-
to 2015, 270 countries get
-
together in Paris with a goal:
-
We want to keep the average warming of the earth below
-
2 degrees Celcius because, if we don't, it's
-
gonna be really bad for everyone.
-
But the problem is no one country can handle this because even the biggest contributors, the U.S. and China, together make up less than
-
half of the pie. Everyone needs to
-
agree to make changes or no one benefits.
-
Worse, the poor countries
-
that have admitted basically zero greenhouse gases
-
are going to be the ones that are most negatively affected by this CO2
-
that's been released by the wealthy countries
-
because they have more food and water insecurity,
-
less access to good medicine, and less infrastructure.
-
It's very difficult to say to them,
-
No! Don't grow your economy using the same dirty fuels and techniques
-
that we used to grow our economies.
-
Instead! Buy these solar panels from us! With the money you don't have!
-
Also, like, since any country that keeps burning its usual will have
-
a competitive advantage in industry. (So, facing climate change) everyone agrees that everyone needs to agree,
-
or this agreement is useless.
-
With advice from scientists, the countries altogether determined
-
how quickly the Earth needs to stop emitting greenhouse gases
-
to meet the 2 degree goal.
-
And then, based on how developed each country is, how many people they have,
-
and how much they're currently emitting, they divvied up that responsibility.
-
At the end, every country had a goal.
-
There was no enforcement for meeting that goal, but there was a goal.
-
And, some countries that had already benefitted a lot from the last hundred years
-
of releasing carbon dioxide even threw in some money:
-
billions of dollars to aid countries that hadn't benefitted from that,
-
to help them grow with less reliance on fossil fuels.
-
Every country agreed to their own path forward, and every country was responsible
-
for figuring out how to meet their goals,
-
whether it's through energy efficiency,
-
subsidizing renewables, regulating businesses,
-
changing people's behavior through education, or
-
ending fossil fuel subsidies.
-
And if countries don't meet their target?
-
Again, nothing happens.
-
There are no penalties.
-
This is an agreement between nations that there is a problem,
-
and we must lead together, or
-
face the price. And, remarkably,
-
A treaty that only encourages countries to reduce
-
emissions with unenforceable promises is
-
a gigantic step, and one that has
-
already seen significant success.
-
But this is an investment, and it does
-
have costs. Do we know
-
exactly what that price will be?
-
No. We don't know precisely
-
how much better off we'll be if we keep temperatures
-
from rising more than 2 degrees Celsius, and
-
we don't know precisely how much we need to reduce
-
greenhouse gas emissions to hit that target.
-
But we do know that we are better off
-
incentivizing these changes now, globally,
-
because more than 600 million people
-
live in areas threatened by sea level rise.
-
Every person on Earth has
-
to eat every single day,
-
and climate refugees' lost crops
-
and lost infrastructure could destabilize
-
the entire world economy and result in
-
a very bad era of human history,
-
a sentiment to which the U.S. Department of
-
Defense, by the way, agrees. Remarkably,
-
thanks to a combination of energy efficiency,
-
changing habits, and a shift from coal to
-
natural gas and renewables, the United States
-
was, until recently, on target
-
to meet its Paris goals for decreasing
-
emissions 26% from 2005
-
levels by 2025.
-
We've already decreased emissions by around 14%,
-
even as the economy has grown.
-
But if there is no political will to continue
-
this, if the majority party in both houses
-
of Congress and the president do not
-
agree that humans are causing climate change
-
and want to continue investing in the same energy
-
systems Thomas Edison pioneered
-
in the 1800s, we will stall.
-
Other countries, at the moment, are pledging
-
to move forward, leading in the absence
-
of the United states. And, several states
-
in the U.S., the ones with the largest economies,
-
also have plans to abide by the
-
agreement. But without the U.S.,
-
a country that emits 18% of the world's
-
greenhouse gases with just 4% of the
-
population, this pioneering agreement
-
is considerably weakened.
-
After all, why would other countries hold
-
up their side of the bargain if the country
-
that benefitted the most from the Carbon Dioxide
-
currently in the atmosphere shirks
-
their responsibility? I, for one,
-
am tired of politicians pretending that
-
we don't all share
-
this big, beautiful, but also quite small
-
planet. I was proud that
-
my country was a leader in establishing the Paris agreement,
-
and I am ashamed at the step backward
-
we have taken away from uniting humanity
-
to take on this great global challenge.
-
John, I'll see you on Tuesday.
