Human activity contributes to this change through the buildup of heat-trapping greenhouse gases. Over time, this increase may be sufficient to cause climatic change, including raising sea levels, altering precipitation patterns and changing water supplies and crop yields. It is also an increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases.

Ocean acidification is progressing rapidly around the world, new research has discovered, and its combining with the other threats to marine life is proving deadly. Many organisms that could withstand a certain amount of acidification are at risk of losing this adaptive ability owing to pollution from plastics, and the extra stress from global warming.
The conclusions come from an eight-year study into the effects of ocean acidification which determined our increasingly acid oceans- a byproduct of burning fossil fuels- are becoming more hostile to vital marine life. Biological Impacts of Ocean Acidification found. Marine life such as crustaceans and organisms that create calcified shelters for themselves in the oceans were thought to be most at risk, because acid seas would stymie them forming shells.
However, the research shows that while these are in danger, perhaps surprisingly, some- such as barnacles- are often unaffected, while the damage from acidification is also felt much higher up the food chain, into big food fish species.
Ocean acidification can reduce the survival prospects of some species early in their lives, with knock-on effects. For instance, the scientists found that by the end of the century, the size of Atlantic cod in the Baltic and Barents Sea might be reduced to only a one-quarter of the size they are today, because of acidification.
What is required over the next three years is concerted action.
Governments will meet in Bonn in November to discuss the next steps on the road to fulfilling the requirements of the Paris agreement, and the researchers are hoping to persuade attendees to take action on ocean acidification as well.Global warming refers to an average increase in the Earth’s temperature, which in turn causes changes in climate.
An increase in the temperature of the Earths surface may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. Global Warming A Deadly Threat For Human Life. Is Global Warming a threat to the Human Population?
Global warming has been a lot in the media and most people have probably discussed it and feared it for an amount of years now.
Ocean acidification is deadly threat to marine life, finds eight-year study Plastic pollution, overfishing, global warming and increased acidification from burning fossil fuels means oceans are. Global warming brings about one of the most dangerous hazards to human life – floods.
As the climate warms, the seas create a thermal expansion, which makes the sea-surface levels increase. 7. Oct 24, · If the outlook for marine life was already looking bleak – torrents of plastic that can suffocate and starve fish, overfishing, diverse forms of human pollution that create dead zones, the effects of global warming which is bleaching coral reefs and threatening coldwater species – another threat is quietly adding to the toxic soup.
global warming and life on earth Global warming presents the gravest threat to life on Earth in all of human history. The planet is warming to a degree beyond what many species can handle, altering or eliminating habitat, reducing food sources, causing drought and other species-harming severe weather events, and even directly killing species that simply can’t stand the heat.
