FRISCO — It’s seems more certain than ever that the buildup of heat-trapping greenhouse gases in the Earth’s atmosphere is pushing the planet’s toward an entirely different state, according scientists in the UK.
FRISCO — The recent slowdown in the rate of global warming is a hiccup on the way to a hotter world, NASA scientists said this week. In fact, Earth is likely to experience roughly 20 percent more warming than estimates that were largely based on surface temperature observations during the past 150 years.
‘We need to put the impact that humans have on this planet into a historic and geologic context’

FRISCO — Most climate projections focus on the on the next 100 years or so, a scale of time that’s comprehensible in the context of a human life, but this generation’s production of heat-trapping greenhouse gases is likely to have impacts far beyond that horizon.
“Politicians may think in four-year terms but we as scientists can and should think in much longer terms,” said Richard Zeebe, a professor of oceanography at the University of Hawai’i. “We need to put the impact that humans have on this planet into a historic and geologic context,” said Zeebe, who recently published a study in theProceedings of the National Academy of Sciences that examines mankind’s long-term legacy of fossil fuel burning.
Doubling of CO2 likely to result in 2.2 to 4.8 degrees Celsius warming

SUMMIT COUNTY — Climate scientists know that greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, but there’s still some uncertainty about how the overall system responds to varying levels of those gases.
By studying the paleoclimatic record, researchers have been able to measure relationships between past greenhouse gas increases and temperatures to some degree, and new research is helping them evaluate past climate sensitivity data to help improve comparison with estimates of long-term climate projections developed by the Intergovernmental Panel on Climate Change.
