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 .
A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [69] [70]
Climate change affects oil and natural gas infrastructure. This is also vulnerable to the increased risk of disasters such as storms, cyclones, flooding and rising sea levels. [271] Global warming affects the insurance and financial services sectors. [145]: 212–213, 228, 252 Insurance is an important tool to manage risks. But it is often ...
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.
It is highly likely that those human activities that have increased the concentration of greenhouse gases in the atmosphere have been largely responsible for the observed warming since 1950. The warming associated with increases in greenhouse gases originating from human activity is called the enhanced greenhouse effect. The atmospheric ...
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 ...
It therefore can be seen as a contributor to global warming. [28] Many ecological effects will be compounded by climate change as well, as ambient temperature rises in water bodies. [11] Spacial and climatic factors can impact the severity of water warming due to thermal pollution. High wind speeds tend to increase the impact of thermal pollution.
The exceptionally warm water of the Gulf of Mexico that supercharged deadly Helene last month was made up to 500 times more likely by human-caused climate change, which also ramped up the ...
