Good reasons to be concerned for future
I am a concerned father, grandfather and community member. Why am I concerned?
1) Two degrees: Almost every government in the world has agreed that any warming above a 2°C (3.6°F) rise would be unsafe. We have already raised the temperature 0.8°C, and that has caused far more damage than most scientists expected. A third of summer sea ice in the Arctic is gone, and the climate dice are loaded for both devastating floods and drought.
2) 565 gigatons: Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere and still have some reasonable hope of staying below two degrees. Computer models calculate that even if we stopped increasing CO2 levels now, the temperature would still rise another 0.8 degrees above the 0.8 weve already warmed, which means were already four-fifths of the way.
3) 2,795 gigatons: A team of London financial analysts estimates that proven coal, oil and gas reserves of the fossil fuel companies equals about 2,795 gigatons of CO2, or five times the amount we can release to maintain two degrees of warming. Eighty percent of these reserves need to stay underground.
There are different approaches to this problem. Bill McKibben says If it is wrong to wreck the climate, then it is wrong to profit from that wreckage. He urges educational and religious institutions, city and state governments, and foundations that serve the public good to divest from fossil fuels within five years.
James Hansen, former NASA climatologist and a founding member of Citizens Climate Lobby (CCL) agrees with McKibben. Hansen and CCL, however, promote a market-based approach of a revenue-neutral carbon tax to combat global warming. The tax would be assessed according to a fuels carbon dioxide equivalent. The idea is to use market mechanisms rather than regulatory measures to discourage fossil fuel use.
I am certainly glad Gov. Kitzhaber has come out in support of a carbon tax.
Bill Gates, on the other hand, has other ideas. If you Google Bill Gates on the worlds energy crisis, you will hear him say: Theres certainly lots of room for increasing efficiency. But can we, by increasing efficiency, deal with our climate problem? The answer is basically no. The climate problem requires more than a 90 percent reduction in CO2 emitted, and no amount of efficiency improvement is going to address that
He then goes on to say that fourth generation nuclear power is safer than all other energy options What happened in Japan is terrible but if you compare that to the number of people coal or natural gas have killed per kilowatt-hour generated, its way, way less ... coal and natural gas have much lower capital costs, and they tend to kill only a few at a time, which is highly preferred by politicians.
Some of Gates statements challenge some of my actions taken so far, but I am glad he is investing in ways to generate energy and therefore reduce CO2 by 90 percent one of the biggest challenges of this century.
Will you join me in working on divesting from fossil fuel companies, and promoting a fossil fuel revenue-neutral carbon tax bill?
