Industrial Revolution is adding to global warming which creates climate changes around the globe to satisfy the needs of the rising population. Whether global warming and climate changes are happening naturally or not is no longer relevant because the fact remains that the overpopulated earth can only mean that it makes matters worse by emitting more carbon into the atmosphere regardless how small they are at a time, but incrementally it will accelerate to a point of no return. What we can do now is to try and slow down the damage already being done. Success is not guaranteed, but doing nothing only exasperates the problem.
Planet Venus was much like the earth one time, but now is like hell. The Southwestern USA is now facing major water shortage problems as less and less water is coming down the Colorado River over the last 20 years, the mighty Colorado River which has carved the Grand Canyon about a mile deep over time. The water levels at Lake Powell at Glenn Canyon Dam and Lake Mead at Hoover Dam are at record low levels as there is less snow melt at the Colorado mountains. Other lakes, natural or man made are all losing a lot of precious water for farming and drinking. Los Angeles, San Diego, Las Vegas, Phoenix and other major cities and towns in this region will continue losing water which will change the life as they know it. This is the reality of Climate Change due to Global Warming.
Let's talk about rising carbon and CO2 levels.
Right now, we have 408 ppm (parts per million) of CO2. This equates to 0.0408% of Oxygen is CO2.
In 1800, we had 300 ppm. Industrialization occured in 1750.
This is all that is proven as fact.
That's because there are many things that emit CO2 and Carbon into the atmosphere. Volcanic Eruptions and big bushfires for a start can emit far more carbon and CO2 than humans are ever able to do. And it happens naturally.
What does however hinder the earth's ability to recover, is the destruction of old growth forests/rain forests. But it still isn't too late. If we protect all our forrests all over the world like some countries have already started to do, then we will be fine.
What is even better is if all countries start massive tree planting programs. Cyprus for instance. Cypriot cities look like cement jungles. Not many trees. If the Government there and every other Government around the planet plant billions and billions and billions of trees, the CO2 and Carbon will be removed from the atmosphere.
I always said, every human should plant 10 trees. That's 65 billion trees. I bet that removes a lot of carbon.
