@geocelta1961 - Yes, the climate was changing naturally, but we accelerated it by a huge amount. We basically dug up all the CO2 that used to be in the atmosphere and put it back into the atmosphere. The rate at which we are putting CO2 into the atmosphere is faster than any natural event has in the past, even including super volcanoes. So, while the climate always changes, we have made a massive impact on it. They can measure this by looking at ice cores and seeing how much CO2 was in the atmosphere before. What you see was slow transitions from low CO2 to high CO2 that took hundreds of thousands of years. We are doing the same thing in hundreds of years. You can already see it with things like British Columbia having 104 deg F last summer. Or how winter is now ending a month early compared to 100 years ago. That is a rapid change on a geological time scale. Anthropogenic climate change (human caused) climate change is a very real thing, and scientists have found that their worst case scenarios are being exceeded. So, while you may not belive in anthropogenic climate change, it certainly believes in itself, lol. It is happening right now, no matter what people think. You aren't going to have the option of dismissing it in the near future. I'm curious how you could dismiss it now, because what normally takes 10,000 years is happening in 10 years. It is about to get really, really rough. Buckle up.

@geocelta1961 - Ya, that is good that you are doing your part, but you are 100% right that it won't matter unless governments and corporations make huge changes. There are some countries that are doing pretty well, like Germany. In ten years, they have gone from 15% renewable energy to roughly 50-60%. They hope to go to 90-100% by 2035. The problem is, a lot of countries will be wanting to switch to nuclear in order to reduce their green house emissions, and estimates suggest with current uranium available to be mined, we probably have 100 years left if most countries start using it. We might find more deposits to mine, but we can't count on that. The alternative is that everyone starts using wind and solar, but that will have to be an international effort since countries will have to rely on power transfer from other countries when they have low sunlight or no wind. Europe is trying to integrate power grids within the EU to achieve just that. We will also have to develop energy storage techniques to a much higher level. We simply don't have the battery technology to store the amount of energy required. So, there are a lot of theoretical solutions right now, but it is a quickly evolving field. The wildcard is fusion energy. If they manage to master fusion energy, our power needs will be met. We will also have enough energy to seriously start building carbon capture machines that you spoke of at scale. But fusion energy is very, very hard. You have to sustain plasma at 125 million degrees Celsius, much hotter than the center of the sun. The sun has a much higher amount of pressure, meaning it doesn't need to get as hot for fusion to occur. Right now I think they have sustained a plasma for like 30 seconds, so we have a long way to go.
Basically, I think we're fucked. We are going to do a lot of damage before we get our emissions under control, and who knows how long it will take for that. Scientists aren't being alarmists when they say it is going to get really bad, they are underselling it if anything. The wildfires in Australia, California, etc... The stronger storms we are seeing. The flooding and rising sea levels. 50% of the world's population lives within 125 miles of the coast, a coast which will assuredly be flooded in the next 100 years. New Orleans will be gone, no saving them. It is going to be bad, and that isn't some pseudoscience alarmist bullshit, it is the honest to God truth.

@geocelta1961 - Scientists have been agreeing for the last 40 to 50 years. That is a very long time in science. Also, records have been released from oil companies showing even they knew 40 years ago. In fact, the basic premise was discovered 100 years ago, the consensus has been for 40 to 50 years. Celebrities are hypocrites, no surprise there. The reason you experienced a really cold day is because the polar vortex keeps breaking up and traveling south. That is a very bad thing, as it means it isn't in the artic where it should be. The Artic is losing ice at a rapid pace, which is why countries like the US and Russia are fighting over Artic sea passages. It wasn't an option before because of all the ice, but that has changed. The last 10 years have been the warmest 10 years on record, and it is only going to accelerate. I wish I could say there is hope, but there really isn't. The devices you are talking about to capture CO2 from the air don't capture near enough to have any kind of effect. Even massively upscaling them wouldn't have much of an effect unless every country started doing it on a truly massive scale, and it would all have to be powred by fission or hypothetical fusion energy in the future. There isn't enough uranium to do it with fission, and we have no clue if fusion will ever be viable. So, pretty much we are fucked. I am a biochemist and I have read much of the primary literature. In addition to this, I have talked to many professors of climate science, and they all say the same thing. We are fucked, so just enjoy the ride.
