As is subtly revealed in the cartoons above, global warming is a real threat to our world.
In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.
The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world.
To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress.
China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy.
With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising.
In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms.
Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.
Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world.

In a word, there is a long way to go before we can take a comfortable world for granted again .

Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters.
Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.
The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels.
What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.
To stop global warming we should make immediate and continual efforts. We hope the situation will soon change.
