article wrtiring on climate change

Answer 1

Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations insolar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.[1]

Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from boreholetemperature profiles, cores removed from deep accumulations of ice, floral and faunalrecords, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change

Answer 2

Climate Change

- by Taylor

Human activities which have a significant impact on the climate are the burning of fossil fuels such as coal, oil and gas, whether in homes, factories, vehicles or in other ways.

Burning fuels releases carbon dioxide gas, a greenhouse gas, besides others. Since the early 1800s, when people began burning large amounts of coal and oil, the amount of carbon dioxide in the earth's atmosphere has increased by nearly 30%, and average global temperature appears to have rice and over by 1°C.

Such a temperature rise will cause changes in the amount and pattern of rain and snow, in the length of the growing seasons, in the frequency and severity of storms, and in the sea level. Farms, forests, plants and animals would also be affected. Humans also cannot escape the effects of this and hence should do their bit to save the environment.
