When Positive is Negative—it's a chain reaction.

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 you see from your window, climate you see from a satellite

‘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.
We must manage the unavoidable & avoid what is manageable

'Scientists say, when it comes to climate change, we need to manage what is unavoidable and avoid what is unmanageable.' — Thomas Friedman, NY Times columnist
Waking the "Sleeping Giants" of abrupt change

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.
No warming since 1998? It's like the tail wagging the dog

'When you focus on just atmospheric heat to measure global warming, it's like tracking the tip of your dog’s tail to determine its location, instead of the body of the dog.' — Greg Laden, biological anthropologist and science communicator.
It's not Vegas.   What happens in the Arctic doesn't stay in the Arctic

Category:Extreme Weather
What happens in the Arctic, doesn't stay in the Arctic. The rapid disappearance of sea ice cover can have consequences that are felt all over the Northern Hemisphere, due to the effects it has on atmospheric patterns.
If left unchecked, this issue will swamp all other all other issues

Category:ALL BITES
“Climate Change is not just another issue. It is an issue that if left unchecked, will swamp all other issues.” — Ross Gelbspan, writer and activist. He wrote two books on global warming: The Heat Is On (1997) and Boiling Point (2004)
If 1º melts the Arctic, we're fools to see what 2º will do

"If 1 degee melts the Arctic, we're fools to find out what 2 degrees will do." — Bill McKibben, environmental author & founder of 350.org
Earth's climate is an ornery beast...that overreacts

Category:ALL BITES
"The paleoclimate record shouts out to us that, far from being self-stabilising, the Earth's climate system is an ornery beast which overreacts to even small nudges." -- Reknowned paleoclimatologist, Wallace Broeker
Climate Russian Roulette:   But what's in the loaded chamber?

Continued release of greenhouse gases is like playing "Russian Roulette with the climate, hoping that the future will hold no unpleasant surprises. No one knows what lies in the active chamber of the gun."

-- Oceangrapher, Wallace Broecker, 1987.
A political issue? That's like choosing sides over E = mc2

"Climate change has taken on political dimensions...That's odd because I don't see people choosing sides over E = mc2 or other fundamental facts of science." — Dr. Neil deGrasse Tyson, astrophysicist, Host of Cosmos: A Spacetime Odyssey.
100% Certainty?  Not even the military requires this to take action

"You never have 100% certainty in anything. If you wait for 100% certainty on the battlefield, something bad is going to happen." — Vice Admiral Dennis McGinn (retired), former Deputy Chief of Naval Operations.
'Little old us? We're not important enough to alter the planet.'

Humans have overrun the planet to live in every ecosphere. We have had a dramatic impact on natural resources in every land we have colonised. But our impact pales in comparison with plankton.
"...Like leaving the 'fridge door open."

As the Arctic warms, so the northern continents at higher latitudes experience cold winters with heavy snow falls. It's rather like the fridge door being left open: warm air goes in at the top as cold air falls out into the room.
