"Climate change could severely reduce the areas suitable for wild Arabica coffee before the end of the century. That is the conclusion of work by a UK-Ethiopian team published in the academic journal Plos One. It supports predictions that a changing climate could damage global production of coffee - the world's second most traded commodity after oil. "

A refrain running through the debate over global warming suggests we need to nothing to slow it, because after all, the climate science predicting more warming could turn out to be wrong. Giordano Bruno was burned at the stake, and Galileo almost was, for objecting to the scientific doctrine that the Sun revolves around the Earth. For two thousand years people believed in systems of physics and astronomy that turned out to be incorrect. And for a few more centuries after that they held to a new celestial mechanics only to see it displaced by relativity theory.

If the pictures of those towering wildfires in Colorado haven't convinced you, or the size of your AC bill this summer, here are some hard numbers about climate change: June broke or tied 3,215 high-temperature records across the United States. That followed the warmest May on record for the Northern Hemisphere - the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average, the odds of which occurring by simple chance were 3.7 x 10-99, a number considerably larger than the number of stars in the universe.

Can robots work as scientists? At first, this seems like a silly question. Computers are pervasive in science, and if you walk into a large university lab today, there's a good chance you'll find a fully fledged robot working alongside the lab-coat-wearing humans. Robots fill test tubes, make DNA microarrays, participate in archaeological digs, and survey the oceans. There are entire branches of science-climate modeling and genomics, for example-that wouldn't exist without powerful microprocessors. Machines even play an integral part in abstract fields of discovery. In experimental mathematics, humans rely on computers to inspire new lines of thinking and investigate hypotheses. In 1976, mathematicians used computers to prove the four-color theorem, and machines have since been used in several other proofs.

Here's some bad news for those of you who like to think you can think rationally about risk. You can't. You know all those thoughtfully considered views you have about nuclear power or genetically modified food or climate change? They are really no more than a jumble of facts, and how you feel about those facts. That's right. They're just your opinions. Which is bad news, because no matter how right you feel, you might be wrong. And being wrong about risk is risky, to you AND to others.

The eminent British scientist James Lovelock, back in the 1970s, formulated his theory of Gaia, which held that the Earth was a kind of super organism. It had a self-regulating quality that would keep everything within that narrow band that made life possible. If things got too warm or too cold-if sunlight varied, or volcanoes caused a fall in temperatures, and so forth-Gaia would eventually compensate. This was a comforting notion. It was also wrong, as Lovelock himself later concluded. "I have to tell you, as members of the Earth's family and an intimate part of it, that you and especially civilization are in grave danger," he wrote in the Independent in 2006.

Not long ago, Cory told you about how the Canadian government has been muzzling scientists-refusing to let them speak freely with the press and, thus, controlling what research the public gets to know about. Not surprisingly, it's research on topics that are politically inconvenient to Prime Minister Stephen Harper's government-climate change, for instance-that end up getting frozen.

UNU Media Centre head Brendan Barrett shares insights derived from a UNU Institute for Water, Environment and Health conference that focused on K* (K-Star) - a spectrum of ideas that covers research communication, science push, knowledge translation, adaptation, transfer and exchange, knowledge brokering and mobilization, and policy pull. * * * To sum up the underlying need for the recent K* Conference 2012, I borrow the words of a co-participant who explained that "as we are seeing with the climate debate and other 'wicked problems', it is not sufficient to assume that scientific consensus about the facts will be influential in policy or the wider community".
