As many people know, climate change is happening at a very fast rate. All of those are not solely because of human beings but some occur naturally. It will negatively impact the people in the future.
A professor and epidemiologist, Anthony McMichael, has written the book "Climate Change and the Health of Nations: Famines, Fevers, and the Fate of Populations" with Alistair Woodward, a former student and noted epidemiologist. Since McMichael has died in 2014, Woodward continued his book. Woodward has explained to National Geographic how different a global warming that is caused by people from the natural calamities and climate changes that occurred in the past. Calamitous famines and transmittable diseases could happen again if people and the government don't act, he added.
The U.S. has a president that does not really believe in climate change even though most scientists are saying it is happening. It is happening because of human activities, industrialization and many other bad activities. But McMichael and Woodward explained in their book that maybe only half of those are from human caused global warming. The natural disasters, plagues and famines have also occurred in the past even though the humans were not doing dangerous activities that add to the global warming.
The increase in the greenhouse gasses will definitely cause the climate change and global warming, stated NASA's Earth Observatory. However, not only those are responsible for it. McMichael's book even explained the thing called feedback loops. He stated the melting of Arctic ice as an example; it melts two to three times faster because of global warming so solar energy is absorbed making the ocean's temperature rise. Because of that, ice will even melt faster, he said.
Everything that is happening is a cycle. Earth heats up, more natural calamities happen. People and the government should work together to really change the landscape. Everybody knows what to do, it just they should realize its importance sooner than later.
