For 30 years we have been told how temperatures have been rising rapidly to the unheard-of level. This is causing polar ice to melt, sea level to rise and has brought about a dangerous increase in extreme weather events. These intense changes would likely present challenges to our society and environment.
The causes of climate change are mainly anthropogenic(人类活动引起的) in nature. Since the industrial revolution, human activities have increased the amount of greenhouse gases in the atmosphere. The increased amount of gases which absorb heat has led to more heat being kept in the atmosphere, causing global warming.
The certainty of global warming can be seen through some of the natural phenomena like the effect on crops and extreme weather conditions around the world. The recent assessment report says that the earth’s average temperature has risen by 0.74 degrees from 1906 to 2005, and that the average temperature will continue to rise. There have also been more violent downpours, and the ice at the world’s poles and on its mountains is melting. The rising sea level is flooding the low-lying countries in Asia and small islands in the Pacific. This may lead to the displacement of millions of people, loss of millions of land and consequently billions of dollars.
Troubled by the serious situation, world leaders came together for the 2015 United Nations (UN) Climate Change Conference in Paris. The climate talks led to 196 countries reaching a landmark agreement that committed nearly every country to lowering planet-warming greenhouse gas emissions to address global climate change. That was certainly an encouraging step for our earth and mankind!
As the world leaders continue to commit themselves to monitor our sick planet, we need to continue to take small steps to heal the world. We don’t have much choice. If only we could just pack our bags and migrate to Mars!
