Expert: Don’t Abandon All Hope

Some scientists believe human activity has already led to a tipping point at which catastrophic global climate change is inevitable. But a leading environmentalist visiting Yale said it’s not too late, as long as humans take immediate action.
Frances Beinecke graduated from Yale College in 1971, part of the first class that included women. She went on to earn a Master’s degree from the Yale School of Forestry and Environmental Studies and then to work at the Natural Resources Defense Council, where she’s been ever since. She recently became NRDC’s president.
She met with small groups of students Monday and gave an address in Dwight Chapel, talking about some of her own mentors, like Sen. Gaylord Nelson, the founder of Earth Day. She said students’ environmental concerns center around global warming and energy “” two intertwined issues. She credited Al Gore’s movie, An Inconvenient Truth, with pushing the issue of global climate change to the forefront, whereas in years past, despite the best efforts of scientists and activists, most people couldn’t grasp its significance because it was hard to see its impact.
Beinecke said in order to pull the earth back from fundamental climatic changes, there must be an 80 percent reduction in carbon emissions by 2050. “In order to do that, we have to move quickly to promoting increased energy efficiency, increased fuel efficiency of cars, dramatically increase the amount of renewables we’re using, both wind and solar, and figure out how to capture carbon from coal emissions from power plants.”
The U.S. gets half its energy from coal, and has 100 new coal-fired power plants in the planning stages. Coal contributes the largest share of carbon emissions of all energy sources, yet she said not one of those plants includes plans to capture the carbon and prevent its release into the atmosphere. She added that, while nuclear power doesn’t release CO2 in the energy it generates, the problems associated with it “” such as nuclear waste disposal and threats to security through nuclear proliferation “” will probably limit nuclear to the 20 percent of the energy mix it currently provides.
Regarding the politics of global warming, Beinecke said she’s very happy that Democratic Sen. Barbara Boxer will be replacing Republican Sen. James Inhofe as head of the Senate Environment Committee. Addressngi global warming is one of her top two priorities, whereas Inhofe has reiterated fairly recently his claim that global warming “is the biggest hoax ever perpetrated on the American people.”
She said the incoming Democrat-controlled Congress offers some hope for progress.
“The way I look at the next two years, because now we’re back into a system of checks and balances, we won’t be in a period of sliding back on environmental laws that we’ve been in for the last six years. This has been a very, very difficult time for environmental protection in the country, and we’ve lost a lot of ground. I’m hopeful we’ll stop that defensive position we’ve been in and look at the affirmative strategies are that we need to address the environmental issues we’re faced with.”

Birth control - the number one pollution solution.

We need to reduce human greenhouse gas emissions by 80% by 2050, huh?
Humans are due to double their CO2 emissions by mid-century. Furthermore, meat production also is rapidly expanding, emitting massive amounts of methane. Finally, as the earth heats up, carbon sinks will become carbon emitters bigtime, counteracting any cuts in human emissions.
In other words, solving global warming with cuts in human emissions is virtually hopeless. In my opinion, the only solution will be engineered: either dimming the sun hitting the earth, or removing the CO2 from the air after it has been emitted.
Nature already removes 4 billion of the 8 billion tons of CO2 mankind emits each year. That is expected to reduce 30% by 2030. I suggest we improve nature's ability to remove CO2 from the air with genetic engineering. Perhaps seeding a GMO into the ocean.
