WebSep 10, 2024 · A continuous record of the past 66 million years shows natural climate variability due to changes in Earth’s orbit around the sun is much smaller than projected future warming due to greenhouse gas emissions. For the first time, climate scientists have compiled a continuous, high-fidelity record of variations in Earth’s climate extending 66 ... WebCarbon Imbalance . Carbon constantly moves between the ocean, atmosphere, biosphere and other components of the climate system. The natural exchange of carbon between these components, called reservoirs, regulates CO 2 in the atmosphere, thereby stabilizing Earth’s temperature. Burning fossil fuels releases carbon into the atmosphere more …
