the earth is hurtling towards a climate danger zone and scientists say greenhouse gas emissions are to blame but what are greenhouse gases and how do they contribute to climate change they're gases in the earth's atmosphere which create a blanket that traps heat while they allow sunlight to pass through them they prevent the heat that the sunlight brings from leaving the atmosphere similar to how a greenhouse works ultimately this is what causes global temperatures to rise since the beginning of the industrial revolution coal-powered steam engines have drastically increased the amount of greenhouse gases emitted into the
atmosphere in 2015 as part of paris accord many governments pledged to keep global warming below 2 degrees celsius this century but temperatures have already increased by over 1.1 degrees resulting in more disasters like flash floods and wildfires carbon dioxide is among the most harmful greenhouse gases on earth along with nitrous oxide and methane gas greenhouse gases are primarily emitted through burning fossil fuels like coal and natural gas for electricity heat and transportation while some gases are more effective than others at making the planet warmer they all remain in the atmosphere for years some for thousands
the u.n secretary general says a new report by the intergovernmental panel on climate change reveals a multitude of broken climate promises by governments and corporations and now the planet is barreling towards a tipping point that could lead to cascading and irreversible climate impacts the earth's temperatures will soon shoot past a key danger point unless greenhouse gas emissions fall faster than they're expected to
