Technological fixes are already helping, but we need to do a lot more than we are. We need to find ways to reduce the amount of fossil fuels we use for shipping, transportation, power generation, and building. We also need legislation and global cooperation to be able to make these things happen. Most companies will prioritize profits instead of minimizing environmental health. That doesn’t mean those companies are malicious, but they don’t focus on how their minimization of costs often shifts cost onto the environment. We need legislation to incentivize companies to reduce their overall impact on the environment. To make this happen we have to be more active about decreasing environmental impact individually and more outspoken about climate change. It may be possible to suck CO2 out of the atmosphere but that could be risky and we need to reduce our pollution to more than just the air.
While climate science is a fairly new science, it is not useless. There is plenty of evidence that global temperatures are rising, and much of that is obviously at least correlated with the rise of CO2 before and after the industrial revolution. The temperature increase has had a visible effect on the north and south poles. The effects of climate change are only going to become more and more obvious as sea levels rise. I don’t understand people who think climate change is not going to have a noticeable impact on the world. Hopefully we can change things before the damage becomes to big to deal with.
