It only means more crops and trees if you magically don't get other effects like drought, heat stress, erosion from drought followed by torrential rainfall, loss of icecap melt for irrigation, invasive insects and disease, and forest fires, all of which we're seeing quite a bit.
And of course we have ways to produce energy now without burning fossil fuels.
- jeejay 4y agoI should admit that my specialty is chemistry and not environmental science so it is hard to make arguments here. Just a few comments: - it should be proven that these other effects are the causes not correlations. - what invasive diseases you are talking about? smallpox or syphilis? - drought was always a thing, e.g. great famine of 1921 in USSR was caused by it. That was way before modern levels of global warming. - There were at least 5 ice ages. Are the humans responsible for their endings? I am convinced that climate is changing — just not fully convinced what is the human role in it.
- DennisP 4y agoSince you have a science background, I'll strongly recommend the recent short book The Physics of Climate Change by Lawrence Krauss, which details how our CO2 emissions change the planet's temperature. It's fairly basic thermodynamics and was predicted with decent accuracy over a century ago. Also there are several chapters in Hansen's book Storms of My Grandchildren that go into the geological record, with multiple lines of evidence that all point to a similar sensitivity of the planet's average temperature to CO2 levels. (Regarding invasive diseases, I meant primarily things affecting forests.)
