However, this wasn't the only time in recent history when a major global event caused emissions reductions. For example, the global recession resulted in CO₂ levels to fall by almost two percent in 2009, while the recession in the early 1980s also had a notable impact on emissions. On...

“Over recent years, concern about a coming hothouse mass extinction set off by human carbon emissions has been on the rise. Studies of Earth’s deep history reveal that at least 4 out of the 5 major mass extinctions occurred during both hothouse periods and during times when atmospheric and...
periods of more intense uplift and erosion (Fig.2b,dand Extended Data Fig.8), the question whether orogenic periods in Earth history are sources or sinks of atmospheric CO2is now a reopened question3,31,49,50. The net balance will depend on factors such as transport of terrestrial ...
to 2050, when the world has to be decarbonised to meet the Paris goals. Compared to Germany, France started this process well ahead and, since decades, avoids the emission of about 300 Mill tons of CO2a year. The history of nuclear power development of Germany is compared in Ref. [16...

In December 2015 the Paris Agreement was passed and its long-term temperature goal was to maintain the increase in the global average temperature to well below 2 °C (3.6 °F) above preindustrial levels and to pursue efforts to limit the increase to 1.5 °C (2.7 °F). China has ...
