Many people don’t believe that global warming is a real threat. Psychologically people don’t want to believe the negative when there are people that try to disprove it. It’s easier to believe that nothing is wrong.
I personally believe that global warming is a threat because I can physically notice it. Just this past winter didn’t feel like winter at all. There was hardly any snow and some days felt like spring in January. But there are some people who refuse to believe that global warming is a real threat. In fact some people believe that there is global cooling.
I don’t believe the global cooling findings because the studies have been done in climates that are already very cold, so a temperature change of one degree doesn’t sound like much of a difference from the normal temperature in those areas of the world.
