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.
A warm-up generally consists of a gradual increase in intensity in physical activity (a "pulse raiser"), joint mobility exercise, and stretching, followed by the activity. For example, before running or playing an intensive sport, athletes might slowly jog to warm their muscles and increase their heart rate. It is important that warm-ups be ...
This is why the temperature change is defined in terms of a 20-year average, which reduces the noise of hot and cold years and decadal climate patterns, and detects the long-term signal. [63]: 5 [64] A wide range of other observations reinforce the evidence of warming.
Climate change, fueled by greenhouse gas emissions, has made eerie warmth more likely in states up and down the US. Non-profit group Climate Central said some cities had felt heat 20 degrees above ...

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 ...
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]
Body proportions of select modern human population groups in relation to temperature. Mean index of tibia/femur length (crural index). [10]Bergmann's rule states that endothermic animal subspecies living in colder climates have larger bodies than those of the subspecies living in warmer climates. [11]
