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 United States Environmental Protection Agency had issued a 100-page report on global warming and human health back in 1989. [ 131 ] [ 144 ] By the early years of the 21st century, climate change was increasingly addressed as a public health concern at a global level, for example in 2006 at Nairobi by UN secretary general Kofi Annan .
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [28]
The combined effects of shifting land use and climate change mean extreme wildfires are projected to become more frequent and intense globally, according to the UN Environment Programme (UNEP).
If the world hits 2 C (3.6 F) of global warming, heatwaves would on average occur 5.6 times in 10 years and be 2.6 C (4.7 F) hotter, according to the WWA.
Heat waves are more likely to occur simultaneously with droughts. Marine heatwaves are twice as likely as they were in 1980. [34] Climate change will lead to more very hot days and fewer very cold days. [35]: 7 There are fewer cold waves. [36]: 8 Experts can often attribute the intensity of individual heat waves to global warming.
Human activity since industrialization has led to a huge increase in the production of carbon dioxide, a greenhouse gas that contributes to rising global temperatures. Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future ...
Overview of climatic changes and their effects on the ocean. Regional effects are displayed in italics. [1] This NASA animation conveys Earth's oceanic processes as a driving force among Earth's interrelated systems. There are many effects of climate change on oceans. One of the most important is an increase in ocean temperatures.
