Researchers reconstructed past global warming and estimated potential future warming using computer modeling. Climate sensitivity was higher during past global warm periods, amplifying the effect of greenhouse gas emissions.
Research team from University of Southampton found that atmospheric CO2 levels during the Pliocene era matched recent years, supporting recent climate change predictions. The study estimates climate sensitivity and reveals differences in climate response between warmer and colder periods.
A new study by Richard Zeebe suggests that amplified and prolonged warming due to unabated fossil fuel burning raises the probability of large ice sheets melting, leading to significant sea level rise. Climate sensitivity may change over time, potentially making future climate change more severe and longer-lasting.
A new approach enables scientists to use past climate data to improve future projections, reducing divergent results. The method classifies and compares over 20 studies, providing a consistent framework for calculating climate sensitivity.
Researchers reconstructed climate sensitivity over five ice-age cycles using a global suite of records, comparing it with changes in greenhouse gas concentrations and Earth-Sun orbital configuration. The study estimates a 3.1-3.9°C temperature increase for a modern doubling of atmospheric carbon-dioxide concentrations.
Research suggests that carbon dioxide emissions must decrease to zero within two decades to limit global warming to safe levels. To achieve this, countries need to reduce their emissions by at least three percent per year.
Research suggests that massive ancient carbon releases caused global warming 55 million years ago, with temperatures increasing by up to 9°F (5°C) in just 10,000 years. The findings imply high climate sensitivity to CO2 and contradict skepticism about the Earth's response to increased carbon dioxide emissions.
Researchers found that even if climate sensitivity is low, massive transition to carbon-free energy technologies is needed during this century. The study suggests developing alternative energy sources now to achieve stabilization at a 2 degree Celsius warming.
