  4.  @Aa-ron01  Do you understand even the basics of climate change, because a lot of people don't. Its pretty simple if you heat up the planet you evaporate more water and sooner or later it will fall out of the sky. Basically it turbocharges the weather. In a nutshell the side of the earth the faces the sun is getting energy pumped into/onto it by a monstrous nuclear furnace. The other side of the planet is dumping excess energy off into space. We are still getting the same amount from the sun on one side but not dumping as much on the other as a result the entire planet has slowly heated up. When its hotter there's more evaporation. If you have more evaporation you have more clouds and eventually you have these events with huge amounts of rain and snow. It was always called climate change by the scientific community it was journalists who called it global warming because that was easier for them to type. Your remark on vegetation is half right. Vegetation doesn't absorb surface water what it does is allow it to be absorbed. The problem with soil (particularly Australian soils) is that when it dries out it switches from water absorbing to water repelling and if you dry it right out its hard to get it back to water absorbing. What vegetation does is help keep moisture in the soil. So it keeps the soil in a water absorbing state so that when it rains the water can soak into the soil. If its dried out then rain can simply run off the land into the creeks and rivers taking topsoil with it. Its one reason why our environmental scientists (not the greenie tree hugging clowns) have been telling us for a while that we have to stop simply clearing land for pasture as we have done. They've now got the evidence that keeping 20% of native trees and vegetation makes our land more productive as it helps maintain the moisture in the soil. Trying to convince people that's true is the next problem.
