In the last few decades, the global warming has become one of the most pressing environmental issues. The Earth’s average surface temperature has risen by about 0.6 °C (1.0 °F) since the late 19th century, and it is projected to rise by another 1.5 to 2.0 °C (2.7 to 3.6 °F) in this century . If these projections are correct, this would be the fastest rate of temperature increase in at least the past 10,000 years . Global warming could have a number of serious effects on our planet: melting polar ice caps, rising sea levels , more extreme weather conditions , and extinction of plant and animal species .
A large body of scientific evidence suggests that human activities are contributing to global warming . For example, greenhouse gases like carbon dioxide and methane trap heat in the atmosphere , causing Earth’s average surface temperature to rise . Greenhouse gas emissions come from a variety of sources, including burning fossil fuels such as coal and oil , deforestation , and agricultural practices .
There are a number of ways we can reduce our greenhouse gas emissions and slow down global warming . One way is to use less energy overall – for example, by using energy-efficient appliances or taking public transportation instead of driving . We can also generate electricity from renewable sources such as solar or wind power , which don’t produce greenhouse gases when they operate. Finally, planting trees can help offset carbon dioxide emissions because trees absorb carbon dioxide as they grow .
Global warming is a complex issue with many different facets – but it’s an issue we need to start addressing now if we want to protect our planet for future generations.
