Harmful algal blooms enhanced by climate change and eutrophication lower oxygen levels, disrupt food webs and cause great loss of marine life. [225] Coastal ecosystems are under particular stress. Almost half of global wetlands have disappeared due to climate change and other human impacts. [226]
Preliminary data from the Copernicus Climate Change Service shows that global temperature anomalies reached between 1.5 and 1.6 degrees Celsius (between 2.7 and 2.9 degrees Fahrenheit) above pre ...
Temperature changes during that time were likely only ±0.1 °C due to natural forcings and ±0.2 °C due to variability in the climate. [ 31 ] : 3, 443 Global anthropogenic greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2 .
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 ...
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 ...
The new chief of the World Meteorological Organization said it looks to her that the rate of human-caused climate change is accelerating and that warming has triggered more Arctic cold outbreaks ...
In 2004, the geologist and historian of science Naomi Oreskes analyzed the abstracts of 928 scientific papers on "global climate change" published between 1993 and 2003. 75% had either explicitly expressed support for the scientific consensus on anthropogenic climate change, or had accepted it as a given and were focused on evaluating its ...
“Recent studies have theorized that rapid Arctic warming, a pace three-to-four times faster than the globe as a whole, may increase the likelihood of extreme weather events owing to a reduced ...
