The National Academy of Sciences is the "Supreme Court" for science. Honest Abe created it 150 years ago to summarize "state of the art" scientific knowledge and advise Congress and the White House. It's been doing this every year since, under every administration.
"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."
Some skeptics view climate science as a house of cards. You pull one card from the bottom and the whole thing collapses. But science is more like a jigsaw puzzle, assembled piece by piece over decades of research. Gradually, the overall picture emerges, until it's unmistakable. Remaining gaps or even a few misplaced pieces don't change the overall picture.
"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.
All scientists are skeptics. The motto of UK's 350-year-old Royal Society is 'Nullius in verba,' Latin for "On the words of no one" or "take nobody's word for it." It is "an expression of its enduring commitment to empirical evidence as the basis of knowledge about the natural world."
"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.
“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.
“It is wrong to pit renewables against nuclear power. We need all hands on deck. Carbon-fee-and-dividend provides a way to avoid contentious discussion and allow competition.“ – Dr. James Hansen
“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.”
"What I’m trying to do is convince people that acknowledging climate change doesn’t make you liberal. It makes you literate." – meteorologist Paul Douglas.
If 97% of experts say a mushroom is poisonous but 3% say it is safe, would you feed it to your kids?
97% of engineers agree bridge ahead will collapse. 3% say not to worry. Would you keep driving?
What do a banana and a piece of coal have in common? Both are made of carbon and both provide us with energy. Coal stores carbon that was in the atmosphere millions of years ago. A banana stores carbon that was in the atmosphere just a few months ago.
Many Earth systems behave like rubber bands, by not reversing smoothly down the same path that they were stretched along. This means that many changes brought about by global warming, such as sea-level rise and drought, will persist for some time even if we manage to reduce atmospheric CO2.
‘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.
"Weather is your mood and climate is your personality." — Dr. Marshall Shepherd, President of the American Meteorological Society
