CLIMATE CHANGE AND GLOBAL WARMING

Climate change

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The green house effect

While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming

The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Consequences of global warming o

There are two major effects of global warming: the increase of temperature on the earth by about 3⁰ to 5⁰C (5.4⁰ to 9⁰ Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below:

·Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.

·Amounts and patterns of precipitation are changing.

·The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

·Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes.

·Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

·Diseases like malaria are returning into areas where they have been extinguished earlier
