The United States faced down authoritarian governments on the left and right. Now it may be facing an even greater challenge from within

Language Intelligence speaks to that urge that we all have to convince others of the rightness of our ideas, and shows how the masters do it in concrete, clear, and concise language.

Nationally-known meteorologist Paul Douglas has a challenge for the Republican presidential nominee

The Guardian has unearthed a shocking new propaganda plan intended to turn the American public against wind energy in the 2012 election cycle.

Climate Scientist Scott Mandia writes an open letter to State Farm Insurance.

The Heartland Institute is preparing a $100,000 school science curriculum on climate change coming to a school near you. Among their logical leaps is a new billboard featuring mass murderers and totalitarians who believe in climate change. This is science?

It turns out that the presidential campaign staffers have it completely, one hundred and eighty degrees wrong when it comes to science. Overwhelming majorities of American voters want the candidates to debate the big science issues facing the country.

You can’t prove that any one of Barry Bonds' 762 home runs was sparked by alleged steroid use. But it did increase his “base state”, raising the overall odds of hitting a home run. You can’t point to any one weather extreme and say “that’s climate change”, but a warmer atmosphere increases the potential for historic spikes in temperature, and more frequent weather extremes.

America needs and deserves a president who can show that he or she understands the importance of basing public policy on the best available evidence, as the founders intended.

What makes The Hockey Stick and the Climate Wars an important addition is the thread of Mann’s evolution in thinking as he followed the simple logic of science where it led, something we want any graduate student to do, and as a result was increasingly forced to defend his work, himself, and ultimately the future of the planet. A harrowing ride through the politics of truth and denial.

Internal documents show organization's strategy, including a climate propaganda effort in K-12 schools by "providing curriculum that shows that the topic of climate change is controversial and uncertain - two key points that are effective at dissuading teachers from teaching science."

Durban ended with an extension of Kyoto, but an erosion of the status of science as an arbiter of future agreements.

"The scientific community owes us more in terms of a better description of explanation about what might lie beneath all of this." But former Bush economic chief Doug Holtz-Eakin says GOP politicians are taking "positions that are divorced from any reality on the policy and from their own history.”

White House Office of Science and Technology Policy (OSTP) budget by a whopping 32 percent. The cuts "will have real consequences on OSTP's operations," said spokesperson Rick Weiss.

Let’s face it–it’s a bad year for Republican Environmentalists like me. About half of the field of Republican presidential candidates once promoted the idea of addressing climate change in some way, but all but Jon Huntsman have backed off this stance to one extent or another.

Most skeptical conservatives are reason-minded thinkers who are simply too busy to assess vast datasets. Those people should consider the following charts.

A new report by the Inspector General of the EPA questions the EPA's procedures in making a 2009 endangerment finding about excess greenhouse gas emissions.

The report "calls the scientific integrity of EPA’s decision-making process into question and undermines the credibility of the endangerment finding," according to Sen James Inhofe, the senate Environment and Public Works committee minority leader.

"It's pretty astonishing when a crowd cheers just to hear verifiable scientific facts," said Otto. "It speaks to how far our national policymakers have drifted from reality."

Hilary Clinton was mocked as paranoid when in 1998 she said that there was "a vast right-wing conspiracy" out to discredit her husband Bill Clinton's presidency. Since then the network of right-wing media outfits, conservative think tanks, merchant scientists, propaganda videographers and corporate-funded astroturf organizations has been broadly documented.

Standing on the capitol steps on a crisp and partly sunny January 20, 2009, newly-minted president Barack Obama said he would "restore science to its rightful place" - what had been a part of the mission statement of Science Debate 2008, the nonprofit grassroots initiative to get the candidates for president to debate the nation's top unsolve science challenges. But today Environmental Protection Agency Administrator Lisa Jackson said the EPA will not meet a court-imposed September 30 deadline to propose rules for limiting greenhouse gas pollution like excess carbon dioxide from power plants.
