The doomsayers of the 1970s were wrong about how quickly the world would run out of oil, but not about the dangers that hydrocarbon consumption posed to the global environment, especially with respect to climate change.
Climate change is a matter of great peril but also one of great promise. We can pioneer the industries of the future, create millions of good-paying jobs, and build the clean energy economy of the future.
Climate change could produce a lot of misery and waste without necessarily leading to large-scale armed conflict, which depends more on ideology and bad governance than on resource scarcity.
I have been described as the grandfather of climate change. In fact, I am just a grandfather and I do not want my grandchildren to say that grandpa understood what was happening but didn't make it clear.
For millions of Americans, climate change is no longer just a chart or a graph. It's the smoke on our tongues from massive wildfires. It's the floodwater invading our homes and record-breaking hurricanes and heat waves.
I am gravely concerned about climate change.
Meat production is one of the leading causes of climate change because of the destruction of the rainforest for grazing lands, the massive amounts of methane produced by farm animals and the huge amounts of water, grain and other resources required to feed animals.
It appears that President Obama is making great progress on climate change, he is changing the political climate in the country back to Republican.
I have written before about why climate change has to be halted. In retirement, I want to look my grandchildren in the eye and tell them about the small role the business and I played in tackling the world's greatest challenge.
As a California state legislator, I supported our cap-and-trade law to force polluters to pay for releasing harmful greenhouse gases to combat climate change.
Maybe more climate activists will think about the climate change not as an international problem to be resolved in an air-conditioned meeting hall, but as a guerilla war to be fought in the streets.
I would much rather we concentrated on the immediate, still-potent dangers, such as nuclear weapons, runaway climate change, and so on. Sort those out, then worry about Hal 9000.
Even if every major government were to slap huge taxes on carbon fuels - which is not going to happen - it wouldn't do much to halt climate change any time soon. What it would do is cost us hundreds of billions - if not trillions - of dollars, because alternative energy technologies are not yet ready to take up the slack.
2007, according to a Harris poll, 71 percent of Americans believed that climate change was real, that it was human caused.
On an increasingly crowded planet, humanity faces many threats - but none is greater than climate change. It magnifies every hazard and tension of our existence.
I think that if we want to cure cancer, we have to teach girls to code. If we want to do something about climate change, we have to teach girls to code. If we want to solve homelessness in our city and our country, teach girls to code. They're change makers.
We are already experiencing the symptoms of climate change, especially with a hotter and drier climate in southern Australia - the rush to construct desalination plants is an expensive testament to that.
Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.
The impacts of climate change are almost immeasurable.
Climate change may not be the most important issue to every American, but strong majorities do consider it a major problem, and they aren't likely to take seriously a candidate who denies the science and who is plainly in the pocket of the polluters.
