paragraph on global warming
Answers
Answer:
Explanation:
Global warming is the long-term rise in the average temperature of the Earth's climate system. It is a major aspect of climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming. The terms global warming and climate change are often used interchangeably. However, speaking more accurately, global warming denotes the mainly human-caused increase in global surface temperatures and its projected continuation, but climate change includes both global warming and its effects, such as changes in precipitation. While there have been prehistoric periods of global warming, many observed changes since the mid-20th century have been unprecedented over decades to millennia.
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.

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.
