The global temperature has risen significantly in the past century. The sea level (around the world) rose more than half a foot in a century. In the last ten years, though, it’s risen more than a foot.
The oceans are also getting warmer. Ice in Greenland and Antarctica is melting. The Arctic sea is not as thick or as broad. The ocean has significantly more acid than it used to, due to increase in the carbon dioxide.
Also, if you watch the news, you’ve probably noticed a number of extreme weather events, such as flooding, hurricanes, wildfires, droughts, heat waves and so on. Evidence suggests that these changes are related to global warming. While this has not been directly proved, many experts agree.
In a nutshell: yes, global warming is real. There is not denying that global temperatures have increased. However, some people still argue that climate change is not that serious, or that it’s not man-made.
Most scientists agree that the main cause of global warming is carbon dioxide, which is man-made. However, some people don’t believe that’s true. Some people believe that global warming is a natural change in the earth. Others say that the measurements are inaccurate. Another debate concerns the long term consequences of climate change and the future.
The scientific opinion on climate change, though, is that humans have caused global warming. According to some polls, only half of the American population believes that humans have anything to do with global warming though. A little odd, isn’t it? Still, there are obviously a lot of different opinions regarding this controversial subject.
