We're already seeing more severe and frequent . Future emissions will determine global warming. With higher emissions, becomes less efficient in absorbing the carbon we emit. Some changes cannot be avoided, but by limiting warming we can , and even stop, many of them. The is that reducing our emissions quickly can limit global warming.
