A school bus goes up a hill, then down. The hilltop is the tipping point. Earth is the bus, but with no driver, just quarreling teenagers, called governments. And no brakes.
The climate system is like a rowboat. It has two stable states. "You can tip and then you’ll just go back. You tip it and just go back. And then you tip it and you get to the other stable state, which is upsihttp://www.climatebites.org/climate-communication-metaphors-and-soundbites/the-consequences-are-bad/abrupt-change/addde down."—Donald Perovich, Army Corps of Engineers.
The Dinosaur Economy is an energy intense economy that relies primarily on fossil fuels such as oil, coal and natural gas that are derived from dinosaurs, plants and other prehistoric biota. The Dinosaur Economy is going extinct because these resources are running out.
"A wait and see policy may mean waiting until it is too late." — 1979 National Academy of Sciences report, Carbon Dioxide and Climate: A Scientific Assessment.
"Global warming will very probably unleash unstoppable planetary forces. And they will not be gradual. The history of our planet’s climate shows that it does not do gradual change. Under pressure, whether from sunspots or orbital wobbles or the depredations of humans, it lurches – virtually overnight." — Fred Pearce
“I don’t believe government should be picking winners and losers in the market place. I want consumer choice and clean air and clean water and solar is the best way to create a competitive choice.” – Debby Dooley, co-founder of the Atlanta Tea Party.
"You don't have to believe in climate change to solve it. Everything we do to raise energy efficiency, will make money, improve security & health, and stabilize climate." - physicist Amory Lovins, chairman of the Rocky Mountain Institute.
Saying 'stopping the Keystone pipeline won't stop global warming,' is like a civil rights skeptic saying in 1960, 'Why Woolworth's lunch counter? Getting served a cup of coffee won't end racism.'
Positive feedback increases change in whatever direction that change is heading—so it's self-reinforcing. While riding a motorbike, what starts as a slight wobble can quickly escalate into a total loss of control; a crash.
‘Weather is what you see outside your window, climate is what you see from a satellite.’ – Scott Mandia, Professor of Physical Sciences at Suffolk County Community College, New York.
The longer global warming continues, the greater the risk of "waking the sleeping giants"—major feedbacks such as ice sheet collapse, methane "burps," or ecosystem collapse—that could ignite abrupt or runaway warming beyond our control.
“UNLESS someone like you cares a whole awful lot, nothing is going to get better. It’s not.” – The Lorax by Dr. Suess
“In science, 95 percent certainty is often considered the gold standard for certainty.” - Seth Borenstein Associate Press science writer
