Question

global warming is a major threat ..write a paragraph on it

Answer 1

There is scientific consensus that the Earth's climate is changing due to global warming/climate change caused primarily by the human use of oil, coal, and natural gas. The burning of these fossil fuels releases carbon dioxide into the atmosphere, which traps more heat from the sun. Global warming/climate change is accelerating as planetary temperatures reach record highs. The melting of polar ice and mountain glaciers may cause sea levels to rise by at least three feet, probably much more, and by eighty feet in coming centuries if the average temperature rises five degrees, warming that will be difficult to avoid. Half of the world's plant and animal species are at risk of extinction by 2100 as habitats are destroyed and ecosystems unravel. The huge Siberian permafrost peat bogs are apparently starting to melt, releasing methane and accelerating global warming/climate change. Antarctic glaciers are sliding into the ocean faster than previously expected, which may result in worldwide coastal flooding. Rapidly melting polar ice caps and glaciers provide visual evidence of global warming/climate change. Indirect effects due to melting polar and Greenland ice can upset the delicate salt balance in the North Atlantic Ocean, triggering a shift in the thermohaline current, which ironically may result in a local ice age in Northern Europe and parts of North America .

Answer 2

Answer:

Explanation:

                                  Global warming

Global warming is a part of climate change and is partially caused by increased greenhouse gases from burning of fossil fuels, deforestation, agriculture, and other industrial causes.

The Earth's temperature had already warmed by 1°C compared to pre-industrial levels. This temperature rise may appear small, but small rises in temperature translate into big changes for the world’s climate. This is because the amount of extra energy needed to increase the world’s temperature, even by a little, is vast. This extra energy is like force-feeding the global climate system.

·Hotter days

·Rising sea level

·oceans are warming

Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.

Rising sea levels will lead to coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas such as the Gulf of Mexico.

Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.
