CLIMATE CHANGE REQUIRES THE WORLD'S ATTENTION
We have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.

In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was "skin and bones ". An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant that the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology.

Then what is causing the increase in the global average surface temperature Climate scientists often mention a key climate process called the "greenhouse effect " which has two common meanings: the "natural greenhouse effect and the "man-made greenhouse effect. The "natural "greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth's climate warm and habitable. Without this process, Earth could not sustain life. However, the "man-made greenhouse effect" has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly.

There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses。
