carbon current levels
One of the most important things is we can put current levels of carbon dioxide and methane into a long-term context,
address climate directly global models provide study
The study does not directly address global warming. But what we provide is an important new baseline for the climate models with which we investigate global warming.
absolutely co2 faster higher increase last rates time
We find that CO2 is about 30% higher than at any time, and methane 130% higher than at any time; and the rates of increase are absolutely exceptional: for CO2, 200 times faster than at any time in the last 650,000 years.
added atmosphere changed climate compared cycles extremely humans information natural piece short showing time
We have added another piece of information showing that the timescales on which humans have changed the composition of the atmosphere are extremely short compared to the natural time cycles of the climate system,
faster recorded rise
Today's rise is about 200 times faster than any rise recorded
co2 found relationship tight
We found a very tight relationship between CO2 and temperature even before 420,000 years,
across climate co2 fact holds indication regimes relationship role strong transition
The fact that the relationship holds across the transition between climatic regimes is a very strong indication of the important role of CO2 in climate regulation.
