Yes, there is still much about global warming we have to learn and research should continue. But the longer we delay, the more CO2 will build up in the atmosphere. It stays there a long time. If we wait too long before acting, we will pass a point of no return and lock ourselves into centuries of global warming. We could pass one of those dangerous tipping points that could make life very difficult. It's a risk we shouldn't take.
