Thursday morning I moderated my first live presidential debate, on Capitol Hill.

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?

Obama has an opportunity to use climate change as a significant wedge issue to shave votes away from Romney among moderate Republicans and Independents who believe science is the best basis for public policy.

When the publication's science editor publishes antiscience propaganda, what can we learn?

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.

My recent Op-Ed gave me a chance to summarize how I feel about the politicization of climate science in recent years - how it's become a bizarre litmus test for conservatism.

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.

The way to counter antiscience thinking is to make science concrete. Hot enough for you?

In a big win for academic freedom over the forces of creeping authoritarianism, the Virginia Supreme Court today sided with the University of Virginia in its fight against Virginia Attorney General Ken Cuccinelli's investigation of former UVA climate scientist Michael Mann.

It's possible that the program identified Bast as the most likely author because so much of the strategy memo appears to be cut and pasted from other Heartland documents. So I decided to take Bast up on his suggestion and rerun my stylometric analyses.

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.

A lot of fuss is being made about the provenance of the Heartland Institute's climate strategy memo. Heartland says it's a fake. I decided to test that.

Secret documents reveal the corporate and fossil-fuel-funded Heartland Institute's plan to feed kids propaganda in their science classes

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."
