than all human activities combined.
The analysis is based on the fact that as the world
warmed following the coldest part of the last ice age 20,000 years ago, the ice deep inside the Antarctic glaciers
warmed more slowly
than Earth's surface, just as a frozen turkey put into a hot oven will still be cold inside even after the surface has reached oven temperature.
This is happening because humans have been producing carbon dioxide (for example, by running cars on gasoline) faster
than plants can absorb it, which makes the
Earth warmer — and much faster
than has happened naturally in the past.
By reconstructing past global
warming and the carbon cycle on
Earth 56 million years ago, researchers from the Niels Bohr Institute among others have used computer modelling to estimate the potential perspective for future global
warming, which could be even
warmer than previously thought.
Mission to
Earth Scientists knew more
than a century ago that adding carbon dioxide to our atmosphere would
warm temperatures.
The rate at which carbon emissions
warmed Earth's climate almost 56 million years ago resembles modern, human - caused global

than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found.
Seniors (31 %) are less likely
than those under age 30 (60 %) to say the
Earth is
warming due to human activity, and are less inclined to favor stricter power plant emission limits in order to address climate change.
Global
warming has been going on for so long that most people were not even born the last time the

«Temperature anomalies are

than Earth's average, study finds.»
For example, the ice ages during the last several million years — and the
warmer periods in between — appear to have been triggered by no more
than a different seasonal and latitudinal distribution of the solar energy absorbed by the
Earth, not by a change in output from the sun.
