New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth’s climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2.

New Investments and Research Indicate Multi-Trillion Dollar Market for Climate Restoration Through Carbon-Capture
Climate restoration is the global movement to remove the trillion tons of excess CO2 from the atmosphere to restore our air to preindustrial levels of carbon dioxide and to preserve the Arctic ice. Given the climate emergency, climate restoration is a critical third pillar of climate action, complementing ongoing mitigation and adaptation efforts. New technologies and natural solutions for reducing CO2 levels in the next 30 years already exist and the costs for global-scale implementation are projected to be less than 1-3% of the global annual GDP.
