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.
The health benefits from climate change mitigation are significant. Potential measures can not only mitigate future health impacts from climate change but also improve health directly. [266] [267] Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. [267]
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 ...
Analysis of such impacts is an important step in understanding current and future adaptation needs and options. [citation needed] As of 2022, the level of warming is 1.2 °C (34.2 °F) above levels before the industrial revolution. It is on track to increase to 2.5 to 2.9 °C (36.5 to 37.2 °F) by the end of the century. [14]
As of 2021 the remaining carbon budget for a 50-50 chance of staying below 1.5 degrees of warming is 460 bn tonnes of CO 2 or 11 + 1 ⁄ 2 years at 2020 emission rates. [13] Global average greenhouse gas per person per year in the late 2010s was about 7 tonnes [14] – including 0.7 tonnes CO 2 eq food, 1.1 tonnes from the home, and 0.8 tonnes from transport. [15]
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
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 fastest way to warm your engine up is to use it, aka drive! Some might tell you that the power steering fluid — the oil that pushes on pumps enabling you to control the car's wheels ...
