Main cause:-

The main greenhouse gas responsible for current global warming is carbon dioxide gas released in the burning of fossil fuels. We must reduce our use of fossil fuels. we must replace coal, oil and natural gas plants for generating electricity by nuclear plants, because they generate the most carbon dioxide. Use nuclear produced electricity for heating homes and other direct uses of heat. Use hydrogen generated by splitting water with nuclear electricity. Plants remove carbon dioxide, but only while they are growing. Rather than putting all the effort into reducing carbon emissions, it may be more cost-effective to put some effort into removing more carbon dioxide. Do not burn wood and replant the forests with fast growing trees. When these trees reach a size at which their growth slows, they would be cut again.
