Wow, was that former one very stupid.
It's a fact that we are heating the planet up in a couple of ways.
We know from computer models of how much added gas content to the air has x amount of effect. We have verified climate change through old trees and ice cores and knew the contents of the air to know it's effect on the earth.
Now for your question. Without a doubt we are heating the planet up. There has not been any shifting in the planets orbit or it's tilt and we can tell how much pollutants we are adding to the air per day, per week, per year. We have a good idea how much is removed by trees and other scrubbing methods the earth uses to try to balance out the gases. We are putting way more into the air than can be removed.
So as we continue to heat the earth the weather changes, It's noticeable how much it's changed if you take the time to look at it.
The green belts we like to call the high food growth line should be migrating away from the equator, more north in the northern half and more to the south in the southern half of the globe. And cutting or gutting the rain forest of trees is so crazy a thing I've ever seen.
Now for the very scary part. Are you old or young. I can not predict exact timeline because I do not have the numbers but here are a couple of very scary parts to watch for.
One of the worst is the loss of glaciers in the mountain regions. This is as I see it one of the most serious problems that will hit the hardest because we need them for these very vital areas, fresh water to drink, to supply farms with and to generate power from the dams. When these go we loose food, drinking water and summer power generation. What we do get by then is mostly from rain and what little snow is there.
China and more importantly in the short term India will loose most of their fresh water and massive death will hit those countries in about 50 years or so. If we do not have Fusion reactors in place and a lot of them we should loose about 1/4 of the worlds population in the next 50 to 100 years. We may loose a lot more if people start to fight over what fresh water is left and knowing how we act from history we will have many wars.
China is already trying to shift their dropping water supply by spending a whopping 60 billion dollars in water irrigation projects and they know it's only a stop gap project.
In India their glaciers are melting very fast now in their main river. Sorry don't know it's name.
We have seen areas turning to desert, it started decades back in Africa and Spain. Their weather patters have shifted away from their normal patterns. But everyone knows about the problems in Africa and how many are starving. Their monsoons have shifted southwards and now it's mostly desert in Somalia and surrounding countries in the Africa area.
We will see more powerful hurricanes and are already seeing water levels rise in the oceans. Just ask anyone living in Sea level states on the east coast of America. It's starting to flood streets on high tides on a regular basis from what I saw on TV.
We are going to need to spend a lot of money we don't have investing in power generation because this is the only way we can live in anyway close to normal, because we will need to rapidly change over to electric cars or hydrogen powered cars, both need a lot of power to make them work on a large scale. We may need to pass a population control world wide law and enforce it to a degree some would call insane but that is a need to happen plan, we will not be able to support even the current population. If we don't do it voluntary we will do it with war, one way or the other. ugs on Fusion power because that is the best way we have of getting along with the changing planet we are seeing change.
In about 100 years if we don't have a solid energy base and lessen the population we may blast our way back to the dark ages.
I for one do NOT hope we are reincarnated. I do not want to come back to this planet in the next 20,000 years min.
If we heat it up enough to release the huge methane pockets in the oceans we will run into a runaway heating that will most likely kill all life above the waterline.
Three ways, Water loss for farming, electric power gen. from dams and clean drinking water.
Weather shifts that move the air currents away from the equators changing where we grow food.
Ocean water levels. We will reduce the land we use by a number that can probably be looked up or has already been done. We will loose a good amount of useable land mass.
