Human caused warming is by increased concentrations of greenhouse gasses such as carbon dioxide. The science of the greenhouse effect is not in doubt - the planet Venus is affected by a greenhouse effect. What is in doubt is the precise relationship between the concentration of greenhouse gasses and temperature rise (and the associated lags). Humans have also emitted sulphur dioxide which has a cooling effect and has tended to mask the warming effect of rising carbon dioxide for much of the last 100 years until the mid-1970's when clean air acts became operative.
On a larger scale, governments are taking measures to limit emissions of carbon dioxide and other greenhouse gases. The Paris Agreement , a voluntary agreement among 118 nations ratified on November 4, 2016, is one effort being enacted on a global scale to combat climate change. As a part of the agreement, each country agreed to take measures to combat climate change, with the ultimate goal of keeping the post-industrial global temperature rise below two degrees Celcius. Another method is to put taxes on carbon emissions or higher taxes on gasoline, so that individuals and companies will have greater incentives to conserve energy and pollute less.
A: Wondering how to stop global warming ? Reduce your own carbon footprint by following a few easy steps. Make conserving energy a part of your daily routine and your decisions as a consumer. When you shop for new appliances like refrigerators, washers, and dryers, look for products with the government’s Energy Star label; they meet a higher standard for energy efficiency than the minimum federal requirements. When you buy a car, look for one with the highest gas mileage and lowest emissions. You can also reduce your emissions by taking public transportation or carpooling when possible.
