Most scientists agree that humans have contributed to climate change. The accelerated burning of fossil fuels and deforestation has led to massive increases in greenhouse gases in the atmosphere, which prevent heat from escaping into space. More carbon dioxide in the atmosphere makes the Earth warmer, but this gas fluctuates because of the carbon cycle and volcanic activity. So, what do you think about climate change? Is it really a cause of global warming?
People who care deeply about climate issues are more optimistic about the effects of human activity on the planet. Three-quarters of Americans believe that climate change is caused by human activity, while 48% are not as concerned. The same percentage of Americans who do not personally care about climate issues are more skeptical. But many people have a good reason for their concerns. And they believe that individual actions and policy changes will make a difference in the future.
According to a recent Pew Research Center poll, American voters are divided on climate issues. Liberal Democrats, for example, believe that climate change is caused by human activity, while conservative Republicans do not. People with a personal climate concern are more likely to believe that climate scientists understand the causes of climate change and the effects it will have on the planet. While liberal Democrats are more likely to support climate policies, conservative Republicans are more likely to believe that such policies will only make things worse.
