"It’s all a game of odds. We’ve never been here before. We just know two things: one, the CO2 we put into the atmosphere stays there for many years, so it is “irreversible” in real-time (barring some feat of geo-engineering); and two, that CO2 build-up has the potential to unleash “catastrophic” warming.
When I see a problem that has even a 1 percent probability of occurring and is 'irreversible' and potentially 'catastrophic,' I buy insurance. That is what taking climate change seriously is all about." —Thomas L. Friedman
Just thermometers, indicating since the 1880 that the Earth is warming due to climate change.
"The evidence for climate change is not a house of cards, where you take one piece out and the whole theory falls apart. It's more like a mountain. Scrape a handful of pebbles off the top, but the mountain is still there."
"...History will not judge us by how much economic growth we achieve in the immediate years ahead, nor by how much we expand material consumption, but by the legacy we leave for our children, grandchildren and their grandchildren. We are consuming what is rightfully theirs by sacrificing long-term progress on the altar of immediate satisfaction and convenience." — HRH The Prince of Wales
"Even small rises in sea level will have very big impact in some places, as storm surges hit coasts. If you raise the floor of a basketball court by just a few inches, you will see many more slam dunks." — Twila Moon, University of Washington
While it's hard to know how much global warming contributes to any single weather event, science tells us that we will see more and more extreme weather as the earth warms. Think of today's extreme weather as a "sneak preview" of what lies ahead on our current path.
"We're driving in a car with bad brakes in a fog and heaing for a cliff. We know for sure now that the cliff is out there, we just don't know exactly where it is. Prudence would suggest that we should start putting on the brakes."— John Holdren.
"What’s more socialist than American taxpayers subsidizing the fossil industry while they fleece our wallets? Perhaps Exxon should be renamed The People’s Oil Company of America." — Richard Whiteford, Environmental Communications Consultant in Downingtown, Pa.
"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.
"When it comes to climate change, true skepticism is two-sided. One-sided skepticism is no skepticism at all." —Michael Mann."I will call people who deny the science 'deniers.' I won't be deterred by the fact that they don't like the use of that term and no doubt that just endears me to them further. It's frustrating of course because a lot of us would like to get past this nonsensical debate and on to the real debate to be had about what to do."
"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’m not a doctor, but I know not to drink arsenic.” – climate scientist Dr. Michael Mann responding to the “I am not a scientist” line used by top Republican leaders.
“I’m not a scientist either but I can use my brains and I can talk to one.” – former Florida Governor Charlie Crist in July 2014 responding to Florida Gov. Rick Scott's line, “I’m not a scientist.”
“If government is broken, we are part of that brokenness and must engage in healing ourselves too.” – Sam Daley-Harris, Founder of RESULTS and the Center for Citizen Empowerment and Transformation.
