Global Warming

WHAT IS GLOBAL WARMING

When CO2 and other heat-trapping emissions are released into the air, they act akin a blanket, holding heat in our atmosphere and thawing the planet. 
Overloading our atmosphere with carbon has far-reaching effects for people all virtually the worldâ€"more extreme storms, more severe droughts, foul heat waves, rising sea levels, and more acidic oceans, which potty affect the very base of the food chain.
Since the early twentieth century, Earths average surface temperature has outgrowthd by about 0.8 °C (1.4 °F), with about two thirds of the increase occurring since 1980. Warming of the climate  system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels. These findings are recognized by the national science academies of all major industrialized nations.
An increase in global temperature will cause sea levels to wax and will change the amount and pattern of precipitation, and a verisimilar expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice.



separate likely effects of the warming include more browse occurrence of extreme-weather events including heat waves, droughts and heavy rainfall, species extinctions due to shifting temperature regimes, and changes in crop yields. Warming and related changes will vary from component part to region around the globe, with projections being more robust in some areas than others. If global mean temperature increases to 4 °C (7.2 °F) supra preindustrial levels, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would more often than non be exceeded throughout the world. Hence, the ecosystem services upon which human livelihoods depend would not be preserved....If you want to get a full essay, point it on our website: Orderessay
