Study: Global Warming Happens Quicker Than Previously Thought

Global leaders currently meeting in Peru for the U.N. climate talks might have come to the summit with the assumption that, based on the current body of scientific research, the Earth wouldn't start warming from today's carbon emissions for 30 to 40 years.
But according to new research, the lag time between carbon emissions and their impact on the atmosphere might actually be much shorter, down to just 10 years, meaning that whatever policy leaders draft and vote on in Paris in 2015 could have a much more immediate impact on Earth's changing climate.
It's important to note that, while this study shortens the estimated time frame between carbon emissions and peak warming, it still reaffirms that CO2 can linger in the atmosphere for years, leading to warming that can persist for centuries, Phys.org reports.
That means any international agreement to curb carbon emissions could have a much more immediate impact on short term climate change effects like heat waves and other extreme weather events, but long term effects like sea level rise and glacial melt would still be felt for centuries to come due to current and past emissions.
