Sentences with phrase «current warming episode»

In the current warming episode, it is clear that CO2 and other human - induced heat - trapping gases are driving the warming.

However, in this current warming episode, the increase in CO2 is largely due to human emissions from the burning of oil, coal, and gas (IPCC Fifth Assessment Report).

So even though past warm episodes may have been initiated by orbital changes that caused warming and thus caused CO2 to rise, which then led to more warming, we know that the current warm episode is being driven by increasing CO2 due to the burning of fossil fuels and the clearing of forests.
