The first year was the best.
And now, after an average of 11 years of CO2 emissions, we’re well on the way to meeting the goal of limiting global warming to two degrees, or 1.5 degrees, above pre-industrial levels.
The first step to keeping global warming below 2 degrees is to keep emissions down, but not too much.
We can do this by reducing emissions below their current levels.
If we want to keep global warming above 2 degrees, the first thing we need to do is reduce the amount of CO02 in the atmosphere.
This is known as the “greenhouse effect”.
The greenhouse effect, which is a well-known term for the phenomenon of increasing temperatures, is driven by greenhouse gases in the upper atmosphere.
CO2 is a greenhouse gas and a lot of CO is absorbed into the atmosphere, and we end up with a net amount of greenhouse gases.
But because CO2 can absorb some of the energy of the sun and absorb some heat from the atmosphere without releasing any of that energy back into space, it can also trap heat in the oceans, which can then be released back into the air.
This can increase the amount and intensity of greenhouse gas emissions, which in turn leads to warmer temperatures and more extreme weather events.
This process is called “forcing”.
The first two years of the carbon dioxide experiment were good.
In 2015, the experiment produced about 4.8 million metric tons of CO 2 in the air, which was about one-tenth of the annual emissions of about 5.8 billion metric tons in 2015.
By 2020, the greenhouse effect had been reduced by a third.
But the experiment wasn’t done yet.
To stay below 2.5 deg C, the emissions needed to keep falling until 2020, when they would start to decline again.
The CO 2 level is a measure of the amount that can be absorbed by a system.
This year, it fell to about 3.3 million metric tonnes.
If the experiment continues this way, by 2021 the total amount of atmospheric CO 2 will fall by about one quarter.
The remaining emissions would then begin to increase again.
That’s not good news for the world.
If CO 2 emissions are going to be declining and greenhouse gas concentrations keep rising, they’ll have to keep rising.
That’s not a problem, since the planet will eventually warm up enough that CO 2 levels won’t matter anymore.
But it’s a major problem if greenhouse gas levels continue to rise.
It means that, if global warming stays below 2 deg C as long as we keep emissions falling, we’ll need to continue to keep up the pressure on our CO 2 emitters.
What we can do to keep CO2 levels downThe best way to keep greenhouse gas CO2 concentrations from increasing to dangerous levels is to reduce emissions as quickly as possible.
The best way we’ve found to do this is to ramp up the CO 2 reduction, rather than reduce it as fast as possible, as we do in this experiment.
The problem is that the ramp-up is expensive, because the reduction needs to happen over a period of years.
The cost of the ramp is about 0.1 to 0.3 per cent of the world’s total economic output.
But that’s a pretty large cost to take.
What does this mean for climate policy?
In this experiment, the ramping up didn’t save the world any money.
The ramping-up saved us money because it reduced emissions while they continued to rise, but it’s not enough to offset the costs of our economic output and the costs to our ecosystems, which could be devastating if CO 2 continues to rise to dangerous concentrations.
But this experiment wasn, and remains, the best we have to do to avoid catastrophic climate change.
This is why it’s important to keep the emissions level under control.
It’s also important to think about how the ramp up can help avoid the most costly of the impacts of climate change: the warming of the oceans.
The oceans have been warming faster than we thought.
At first glance, this may seem like a small thing.
The oceans have warmed much faster than our climate models predicted, because they are absorbing more of the solar energy than the sun’s atmosphere does.
But the oceans are also absorbing heat from more powerful storms, which heat up the atmosphere more quickly.
So when we increase CO 2 concentration in the ocean, we increase the ocean heat uptake and it causes more warming in the waters.
It causes more storms, and more storms mean more intense storms.
The result is more severe weather, which leads to more heat waves and more severe storms.
If atmospheric CO2 concentration continues to climb, the oceans will continue to warm faster than climate models predict, and oceans could start to warm much faster.
So how can we reduce the rate of rise of CO- 2 concentration?
The key to reducing CO-2 concentrations in the deep oceans is to slow down the rate at which they increase. The
