We will still be alive in 200-300 years, but life will be different. There will be no fossil fuels, at the rate we're at now. (Rolling Stone reported in 2004 that if fuel consumption stayed at a constant rate, we'd run out around july of 2010.) We'll probably be running on solar power.
Other than that, there won't be much of a change.
As of now, there is nothing headed towards earth. No huge cataclysmic events are in the near future, from what we can determine.
If anything, we will destroy ourselves. Which, personally, I think is a poetic end to what we've done to earth. Earth will move on without us. We're not as big as we think we are. If you think about Earths
life as a clock face, we've only been around for a few seconds. The earth was okay before us, and it will be okay after us. We've not reaped as much havoc as we like to think we have.
Global warming is real, but its not what most people think it is. The Earth has seasons, like the hemispheres have seasons. The ice age was winter. The hot period when dinosaurs lived was summer. The periods in between those were spring and fall. We're in spring right now. The warm up from the Ice Age. The only difference here is that the Earth's seasons last for thousands and thousands of years instead of a few months. The only thing we've done is sped up the warming period by a few hundred years.
Now, by the way I'm talking about that, I don't want you to get the idea that what we've done isn't bad. Because it is. We've released more carbon dioxide into the atmosphere than what was supposed to be there. The industrial revolution and cars are to blame for this. There isn't enough oxygen in the atmosphere. Removal of the rain forests isn't helping either. Thats why Dinosaurs couldn't live today. There's not as much oxygen in the same amount of air that there would have been a couple million years ago.
We can't change what we've done. The Earth is changing around us. We're at the end of our warming period, and we're about to hit summer. Probably in the next couple hundred years. But we're not going to wake up one morning and bam, no water and we're in a desert. It won't happen that way. Summer doesn't happen that way. Summer is gradual. Its slowly going to get warmer, and warmer and stay warmer year round. But what global warming has done has changed that. Its taken a few hundred years off our transition period. The time when humans are going to need to adapt and change, and we will, it will just be harder.
People change. Its why we've lasted as long as we have. We're adaptable. You can take a strong, healthy person and put them out into the woods and if their minds haven't been mottled enough by technology, they could survive. You could put someone out in the cold, and they could survive. Its what makes us the top of the food chain. We can change. And we will.
Life isn't going to just end all of a sudden unless its some kind of apocalyptic nuclear war. I can't speculate much on that. But I can tell you that global warming isn't going to kill us. You really don't need to worry about all of humanity ending in a few hundred years. we're really an amazing species if you give us a chance.
