Is it too late to stop climate change?

Can it be stopped?

But reducing those emissions is easier said than done. Climate change has become mired in politics as many policy makers don't want to admit that humans are to blame for Earth’s escalating temperature. They say warming is part of Earth’s natural cycle. Nevertheless, most reputable scientists agree that humans are responsible. For centuries we have been burning oil, coal and other fossil fuels to power our lives, and at the same time spewing tons carbon dioxide and other heat-trapping gasses into the atmosphere. Those gases act like an invisible blanket, trapping the sun’s heat close to Earth’s surface.

Yet all is not lost. In recent years, many countries have taken significant steps to reduce their carbon footprint. In addition, various industries are experimenting with alternative, cleaner-burning fuels, such as wind and solar, to power their factories. Car companies are now building hydrogen- and electric-powered cars to replace gasoline as the fuel of choice.
