A Texan is standing in flood water. A protest sign next to him reads "Hey, Obama... forget about climate change and focus on ISIS." Texan: I'm fine... but my sign is ruined!
I expect the global warming deniers to show up any minute now, so let me anticipate:1. The Earth is warming faster than it normally would according to natural cycles – solar cycles indicate we should be cooling (so you can’t say it’s a normal cycle)2. Human beings are the reason the Earth is warming because of the disproportionate amounts of CO2 we have pumped into the atmosphere with the burning of fossil fuels and deforestation which reduces the amount of CO2 that is sequestered by nature. (And yes, we can trace patterns of CO2 back 800,000 years, thanks to Antarctic ice cores.) (http://news.nationalgeographic.com/news/energy/2013/05/130510-earth-co2-milestone-400-ppm/)3. Scientists have been warning about this being an active concern for approximately fifty years. There was NO POINT where most climate scientists were claiming we were going into an Ice Age (in the 1970s, most researchers were already convinced that Anthropogenic Global Warming was happening). 4. The idea is neither new nor politically motivated. It was first suggested by Swedish scientists Svante Arrhenius in 1896 – over a hundred years ago – and he even provided a decent estimate of CO2-to-warming amounts. (http://www.lenntech.com/greenhouse-effect/global-warming-history.htm)5. Increased CO2 is not “better for plants,” any more than too much oxygen or too much water is good for us. Increased CO2 has negative effects as well. (http://www.skepticalscience.com/Increasing-Carbon-Dioxide-is-not-good-for-plants.html)6. We will not be able to “just adapt” quickly. Evolution takes a long time, and in practice will kill off many species or creatures until we get better-adapted genetics — and this is what is happening.7. The idea that climate is “always changing” does not mean we are not responsible for a direction of change, nor that the current change is normal, expected, or appropriate. 8. Just because CO2 is a small percentage of the atmosphere does not mean it is not dangerous. We are at a tipping point, where a little more CO2 means a lot more trapped heat. A better way to think about it is that we have nearly doubled the CO2 in the atmosphere. (http://www.skepticalscience.com/CO2-trace-gas.htm)9. There is no “global warming pause.” The heat has been going into the oceans. Average global temperatures have been increasing just the way one would expect if we were warming it. And we are. (http://www.salon.com/2015/02/26/scientists_just_blew_apart_the_myth_of_the_global_warming_pause/)10. For those who think we can’t affect large climates – it’s happened before. It is thought that the reforestation of North America after 90-95% of the native peoples died of European diseases dropped global temperatures notably.11. For those who think that God won’t let this happen – God helps those who help themselves. And if you believe Genesis, we were made stewards of the Earth.
