who to believe
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.
"...Climate change could have significant geopolitical impacts around the world, contributing to poverty, environmental degradation, and the further weakening of fragile governments. Climate change will contribute to food and water scarcity, will increase the spread of disease, and may spur or exacerbate mass migration."
"If 98 doctors say my son is ill and needs medication and two say, 'No, he doesn't, he is fine,' I will go with the ninety-seven. It's common sense - the same with global warming. We go with the majority, the large majority." -- former Governor Arnold Schwarzenegger
"...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
The most credible sources are the "grunts" working on the front lines of research -- drilling the ice cores, taking the measurements, crunching the data, and publishing their findings. Their loudest critics are talking heads, desk jockeys and radio hosts who take "pot shots" at research but have never done it themselves.
"Do you consult your dentist about your heart condition? In science, as in any area, reputations are based on knowledge and expertise in a field and on published, peer-reviewed work. If you need surgery, you want a highly experienced expert in the field who has done a large number of the proposed operations."
"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.
“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.”
'Who wants to be fired on Tuesday? To some degree, this is the dilemma for the right of center politicians. If they roll out climate change the wrong way, the next thing they know they receive a climate hero award and an unemployment paycheck.' – Admiral David Titley, Professor of meteorology at Penn State University and Retired Rear Admiral of the U.S. Navy.
"We desperately want to believe that big problems are overblown or nonexistent. Whenever a group of people 'desperately wants to believe' something, there will always be someone willing to tell them what they want to hear, whether the opportunists are charlatans or simply nutjobs."
