Some, while admitting that climate change is real, argue that it isn't a big deal, that human causation hasn't been proven, and that doing something about it would cause job losses and hurt the economy. Apparently these people don't read newspapers, or if they do, they read the ones that use very small words. Science has known about climate change and the human activity causing it for over 5o years. The science is entertainingly explained in under an hour in the Cosmos episode, The World Set Free.
A July 8, 2015 Guardian headline states, "Exxon knew of climate change in 1981, email says – but it funded deniers for 27 more years." Why do you suppose Exxon did that? Let me take a guess. Because it would cause job losses and hurt the economy. That's oil industry jobs and the oil industry economy.
Keeping a secret for 27 years in order to protect your business model is shortsighted. It would have been more sensible to diversify and develop other energy sources. Had Exxon done that, today it would be an industry leader in renewable energy. But it chose to be dishonest and self-serving instead.
Many of the politicians who argue that climate change interventions will cost jobs and hurt the economy receive major funding from oil industry associates. But that, in itself, doesn't make the argument a bad one. It's true that climate change interventions will cost jobs and effect the economy. The effects will be primarily in the energy sector, although not all of it. Those portions of the energy sector invested in renewable energy will instead create jobs and thrive.
The argument is deceptive because it doesn't take the entire economy into account. Climate change is already affecting the economy's agricultural sector. Droughts, floods and crop-killing heat waves are happening now and will become worse. Climate change will devastate jobs and economies far beyond what can be gained by protecting the status quo. It's time to cut the crap and act responsibly.
