Due to global warming and increased glacier melt, thermohaline circulation patterns may be altered by increasing amounts of freshwater released into oceans and, therefore, changing ocean salinity. Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling. [22]
Communication of the science of how water systems work is an important aspect when creating a management plan to conserve that system and is often used for ensuring the right management plan to be put into action. [11] The conservation of water is extremely important in order to preserve wildlife habitats.
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.
Water covers 71% of the Earth's surface. Of this, 97.5% is the salty water of the oceans and only 2.5% freshwater, most of which is locked up in the Antarctic ice sheet. The remaining freshwater is found in lakes, rivers, wetlands, the soil, aquifers and atmosphere.
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]
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 ...
Even if nations meeting in Paris curtail carbon emissions, a growing number of communities will be exposed to threats caused by climate change. Vulnerable populations that live near water or in arid places will face massive disruptions to their way of life: Flooding and severe drought are on course to become much more common. +2 degrees +4 degrees
