share some interesting stuff about global warming

Answer 1

Hi,


GLOBAL WARMING

Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system, and its related effects. Multiple lines of scientific evidence show that the climate system is warming.

Global warming is primarily a problem of too much carbon dioxide (CO2) in the atmosphere—which acts as a blanket, trapping heat and warming the planet. As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations, carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices aggravate the problem by releasing other potent global warming gases, such as methane and nitrous oxide. See the pie chart for a breakdown of heat-trapping global warming emissions by economic sector.

The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. There is a scientific consensus that climate change is occurring, and that human activities are the primary driver. Many impacts of climate change have already been observed, including glacier retreat,changes in the timing of seasonal events(e.g., earlier flowering of plants),and changes in agricultural productivity.Anthropogenic forcing has likely contributed to some of the observed changes, including sea level rise, changes in climate extremes, declines in Arctic sea ice extent and glacier retreat.


Hope it helps

Answer 2

Global warming is the increase of earth’s average surface temperature and its oceans due to greenhouse gases released as people burn fossil fuels. These greenhouse gases such as carbon dioxide and methane absorb heat that would otherwise bounced off the Earth’s surface. Global warming has emerged has one of the most biggest environmental issue in the last two decades.As per NASA, “the global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.” It seems that the temperature is rising at a rate faster than ever before. Human activities like burning of fossil fuels, deforestation, industrialization and increase in pollution are considered as few of the factors responsible for rise in global warming.
