Which one of the following statements is patently false? Global greenhouse gas emissions need to be cut by 32 gigatonnes to limit global warming to 1.5 degrees Celsius on average. Global greenhouse gas emissions need to be cut by 15 megatonnes to limit global warming to 2 degrees Celsius on average. If we can cut greenhouse gas emissions by 2.7% every year over the next decade or so, we can limit global warming to 2 degrees Celsius on average. If we can cut greenhouse gas emissions by 7.6% every year over the next decade or so, we can limit global warming to 1.5 degrees Celsius on average.
