Drivers of climate change from 1850–1900 to 2010–2019. Future global warming potential for long lived drivers like carbon dioxide emissions is not represented.. The scientific community has been investigating the causes of climate change for decades.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
In 2022, the Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report on climate change. It warned that greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030 to have a good chance of limiting global warming to 1.5 °C (2.7 °F).
While climate change skeptics like Sen. James Inhofe, R-Okla., have pointed to the continued existence of cold weather as a sign that global warming is a threat that humanity need not take ...
Tapio Schneider, a climate scientist at the California Institute of Technology, said the worrying implication of the research is if global warming is responsible for a substantial amount of cloud ...
Some climate change deniers have argued that solar variation is a significant contributor to the observed global warming, which would reduce the relative importance of human-made causes. However, this is not supported by scientific consensus on climate change .
Pope Francis on Wednesday appealed to climate change deniers and foot-dragging politicians to have a change of heart, saying they cannot gloss over its human causes or deride scientific facts ...
On a scale of 1 out of 7, where higher numbers indicated greater disagreement, "global warming is already underway" had a mean rating of 3.4, and "global warming will occur in the future" had an even greater agreement of 2.6 Surveyed scientists had less confidence in the accuracy of contemporary climate models, rating their ability to make ...
