The effects of climate change vary in timing and location. Up until now the Arctic has warmed faster than most other regions due to climate change feedbacks. [164] Surface air temperatures over land have also increased at about twice the rate they do over the ocean, causing intense heat waves.
Natural forces cause some variability, but the 20-year average shows the progressive influence of human activity. [2] Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider effects on Earth’s climate system.
A 2019 review of scientific papers found the consensus on the cause of climate change to be at 100%, [6] and a 2021 study concluded that over 99% of scientific papers agree on the human cause of climate change. [7] The small percentage of papers that disagreed with the consensus often contained errors or could not be replicated. [8]
Climate change is driving extreme weather. By all accounts, the last few years have been brutal for the climate — and for the humans and other living things within it. Around the globe, heat ...
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 ...
Climate change threatens to unravel decades of progress on improving human health through extreme heat, air pollution, disruption of food systems and the spread of disease, the World ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, the scientific consensus is that it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times." [1]: 3 This consensus is supported by around 200 scientific organizations worldwide. [2]
