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 ...
Climate change has led to the United States warming by 2.6 °F (1.4 °C) since 1970. [3] The climate of the United States is shifting in ways that are widespread and varied between regions. [4] [5] From 2010 to 2019, the United States experienced its hottest decade on record. [6] Extreme weather events, invasive species, floods and droughts are ...
For example, climatologist Kevin E. Trenberth has published widely on the topic of climate variability and has exposed flaws in the publications of other scientists. [6] [7] [8] For past debates and controversies on scientific details see for example: History of climate change science#Discredited theories and reconciled apparent discrepancies ...
La Niña is a natural climate pattern marked by cooler-than-average seawater in the central and eastern Pacific Ocean. When the water cools at least 0.9 degree Fahrenheit below average for three ...
The December 2020 Lancet Countdown review concluded that trends in 2020 showed "a concerning paucity of progress" in numerous sectors, including "a continued failure to reduce the carbon intensity of the global energy system, an increase in the use of coal-fired power, and a rise in agricultural emissions and premature deaths from excess red meat consumption.
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."
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 ...
Climate change's increase of water temperatures intensified peak wind speeds in all eleven 2024 Atlantic hurricanes. [16] 1 July (reported): Hurricane Beryl, the earliest Category 5 storm on record in the Atlantic, [17] broke records for rapid intensification (65 mph in 24 hours), overall strength, and location for June.
