Facts about Global warming

Facts about Global warming

Fact 1: Global warming is the result of increase in the earth's average surface temperature due to greenhouse gases like carbon dioxide and methane . These gases are required for the presence of human life on earth. However, global warming is happening due to over-emittance of these gases.

Fact 2:: Emissions like carbon dioxide, nitrous oxide and other greenhouse gases will remain in the atmosphere for many years making impossible to eliminate global warming for several decades.

Fact 3: The Arctic ice is melting rapidly. By 2040 the region is expected to have a completely ice free summer, or even earlier.

Fact 4: Global warming that is causing extreme weather changes has shown it implications in the way of forest fires,heat waves and severe tropical storms throughout the world.

Fact 5: Thee has been a tremendous increase of water vapour, carbon dioxide, methane nitrous oxide especially greenhouse gases due to polluting substances emitted as a result of industrialization, pollution, deforestation.

Fact 6: Humans are emitting more carbon dioxide in the atmosphere, faster than the absorbing rates of plants and the ocean.

Fact 7: Melting of glaciers will cause sea levels to rise on one hand and water shortages in areas that depend on natural sources of water.

Fact 8: Increasing temperatures will release more greenhouse gases, unlock methane, and cause more evaporation of water.

Fact 9: Due to industrial revolution, the burning of fossil fuels like coal, oil and gas started on a massive scale. This not only increased greenhouse gases but was also responsible for large scale deaths due to asthma and other respiratory diseases.

Fact 10: Global warming can lead to massive food and water shortages and has a life threatening impact on the wildlife.

Impact of Global Warming on Animals

Impact of Global Warming on Animals Loss of Habitat As global warming causes climate change, many great deserts like the Sahara, are no longer able to sustain their animal population. Loss of habitat is most vividly seen in the Arctic, where global warming is melting the glaciers, pushing the polar bears into extinction, The melting glaciers have caused water levels to rise in many oceans, threatening to drown many tropical islands and forests, that teem with animal life. Loss of Food Grasslands are also adversely affected by global warming. The effects include high rate of evaporation, higher temperatures, frequent and severe droughts, reduced rainfall, and lower nitrogen content in forage grasses. Lower nitrogen concentration in the vegetation causes improper digestion in animals resulting in reduced strength, performance and health of animals. To make room for an ever-growing population, many forests, grasslands, and even desserts, have been made habitable fo...

CAUSE - CO2 AND CLIMATE CHANGE

CAUSES OF CLIMATE CHANGE CO2 AND CLIMATE CHANGE The most well-known and the most important greenhouse gas is CO2. The concentration of CO2 in the atmosphere is subject to variation even without human intervention. The carbon cycle causes an exchange of CO2 between the biosphere and the oceans on the one hand and the atmosphere on the other. Vast amounts of CO2 are also released by the burning of fossil fuels. there is incontrovertible evidence that the CO2 concentration in the air has never been so high in 8,00,000 years(probably even 60 million years) as it is now. The trend suggests that CO2 emissions will continue to rise globally, although the economic crisis did prevent a rise in 2009. Besides CO2, methane (CH4), nitrous oxide (N2o), fluorinated gases, ozone (O3) and water vapour are important greenhouse gases. Water vapour plays a unique role as it strengthens the heat-trapping effect caused by other greenhouse gas emissions. This is beca...

causes of global warming

What causes global warming? Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect. the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The country’s second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion tons of CO2 emissions a year. Reducing the amount of electricity generated from coal and gas and increasing the amount of electricity from clean, renewable energy sources like solar and wind, mea...
