There are years of solid evidence that show the climate is warming. Still, some people say it is not.
A new United Nations’ report on climate change is alarming. It says the temperature in the atmosphere is rising. They predict a rise of 3.6°F in the not-too-distant future. This may make life on earth almost unsustainable. In the future, there will be:
- food and water shortages;
- melting ice sheets and shrinking glaciers;
- rising sea levels and widespread flooding and
- massive migrations of people.
Scientists say it may not be possible to keep this from happening. At best, life on earth will be unpleasant. At worst, it will be uninhabitable. The worst could happen by the end of this century. Scientists say the world should not give up.
Scientists from many countries are meeting in Lima, Peru to discuss threats to the climate. The U.S. is taking climate change seriously. It has already agreed with China to lower greenhouse gases. Diplomats say this is a good sign. It should inspire other countries.
However, it is still a matter of poor countries versus rich countries. As countries develop, their populations grow, and they use more resources. Rapid growth makes it hard to control pollution.
In the U.S., politics get in the way. Many conservative Republicans do not believe in climate change. They are called deniers. If they are wrong, the world is headed for disaster. Today, they will not take steps to address the problem if it means jobs will be lost or costs will go up.
It is difficult to predict when climate events will be felt so denial is no longer possible.
