This guide is a definitive who's who of the UK's tweet elite. Although for some reason they included me on the list (at #47, same as Armando Ianucci). Why haven’t we cured cancer yet? – How many times have you been asked this question, how many times have you asked this question yourself? The answer boils down to the fact that cancer is not a single disease, it's hundreds of different diseases. Asking that question is like asking, "why haven't we cured viral infection?" or "why haven't we cured car accidents?". Even if we can cur...

Those monsters are actually killing the environment. And it’s not the amount of electricity they use, either. Most large grocery store fridges use hydrofluorocarbons (HFCs) to keep the food cool. While HFCs are ozone-neutral (which is why they replaced the ozone-depleting CFCs and HCFCs back in the 1990s), they have about 3,900 times the global warming effect of carbon dioxide. In fact, one ton of HFCs produces a global warming effect that’s the same as one billion car trips to the grocery store. The Environmental Investigation Agency (EIA) is trying to raise awareness about the environmental problem, but not many supermarkets are respon...

We didn’t have bug bites on every limb, and we could spend a summer evening lounging on our porches without swatting and scratching every two seconds. But those days are over, so we might as well make the best of it. We were thrilled to hear that something we do in the summer anyway could actually keep bugs away. According to Lifehacker, using a fan (both indoors and outdoors) disperses the carbon dioxide you emit. Carbon dioxide is one of the major chemicals that attracts mosquitos.

The heat makes us cranky, so imagine how overjoyed we were today to learn that the U.S. Department of Energy’s National Renewable Energy Laboratory has invented a new air conditioning process that would use 50-90% less energy than today’s most energy-efficient units. There will also be no CFCs of HCFCs used in the machines. One pound of either of those chemicals contributes to global warming as much as 2,000 pounds of carbon dioxide. Whoa.

MichaelsI see that my colleague Sallie James has already blogged on the inherent protectionism in the Senate’s long-awaited cap-and-tax bill.  A summary was leaked last night by The Hill. Well, we now have the real “discussion draft” of  “The American Power Act” [APA], sponsored by John Kerry (D-NH) and Joe Lieberman (I-CT).  Lindsay Graham (R-SC) used to be on the earlier drafts, but excused himself to have a temper tantrum. So, while Sallie talked about the trade aspects of the bill, I’d like to blather about the mechanics, costs, and climate effects. If you don’t want to read the excruciating details, stop here and note that it mandates the impossible, will not produce any meaningful reduction of planetary warming, and it will subsidize just about every fo...

MichaelsToday’s New York Times reports that President Obama has “ordered the rapid development of technology to capture carbon dioxide emissions from the burning of coal,” as well as mandating the production of more corn-based ethanol and financing farmers to produce “cellulosic” ethanol from waste fiber. You’ve got to like the president’s moxie.  Faced with his inability to pass health care reform and cap-and-trade, he now chooses to command the impossible and the inefficient. Most power plants are simply not designed for carbon capture.  There isn’t any infrastructure to transport large amounts of carbon dioxide, and no one has agreed on where to put all of it.  Corn-based ethanol produces more carbon dioxide in its life cycle than i...

Obviously, a brief post can not substitute for detailed studies of professionals in a variety of scientific disciplines – climatology, atmospheric physics, chemistry, geology, astronomy, and economics. However, a short post can summarize basic theses on the main trends in climate evolution, on its forecasts, and on its actual and projected effects. 1. The Earth’s climate is constantly changing. The climate was changing in the past, is changing now and, obviously, will be changing in the future – as long as our planet exists. 2. Climatic changes are largely cyclical in nature. T...

Michaels25,000 bureaucrats, factota, hangers on, and representatives of various environmental organizations have just converged on Copehagen for the UN’s latest “Conference of the Parties (COP) to its infamous 1992 climate treaty. Expect a lot of heat, not much light, and a punt right into our next election. President Obama says that the US will agree to a “politically binding” reduction of our emissions of carbon dioxide to a mere 17% of 2005 levels by 2050. This will allow the average American the carbon dioxide emission of the average citizen in 1867. Obama’s pronouncement has stepped all over the toes of the US Senate, which really doesn’t want to vote on similar legislation this election year.

Harry Reid and other democratic leaders in the Senate have clearly indicated that cap-and-trade legislation will be put off at least, until what they call “spring”, which is long after the upcoming UN climate conference in Copenhagen next month. At the same time, President Obama has said that the U.S., along with China, will announce some type of emissions cap in Copenhagen. Obviously this cannot refer to legislation that has yet to be voted on in the Senate. President Obama keeps using the language “operati...

I was struck by this vignette: But even before the late-night session in July, Obama had begun to educate himself about energy and climate and to use those issues to define himself as a politician, say people who have advised him. He read a three-part New Yorker series on climate change, for instance, and mentioned it in three speeches. It’s great that he read a three-part series in the New Yorker. But has the president ever actually read anything by a climate change skeptic? Actually, a better term would be “a climate change moderate.” Leading “skeptic” Pa...

I report on his fascinating work in the March issue of Intute Spotlight. The process involves using solar power to chemically reduce carbon dioxide back to a combustible hydrocarbon. Grimes suggests that a flow system employed on fossil fuel burning power station chimney stacks could scrub out the carbon dioxide before it enters the atmosphere and provide us with a viable additional energy source.

Cyanobacteria are able to fix CO2 into carbohydrates. Cyanobacteria vary considerably in their ability to consume organic carbon from their surroundings. Many strains are obligate photoautotrophs where the sole carbon source is CO2, while others are able to perform photomixotrophic or even heterotrophic growth using a wide variety of organic substances. Cyanobacteria constitute a unique case where the anabolic and catabolic carbohydrate metabolisms function in the same cellular compartment. In addition, the photosynthetic and respiratory electron transport pathways share components in the thylakoid membranes. Despite its importance to our understanding of cyanobacterial metabolism,...

The findings suggest panic is an inborn survival-oriented response. The results may be relevant for a better understanding and the further prevention of emotional disorders. It has been known for years that small amounts of carbon dioxide provoke a panic reaction in certain anxiety-prone individuals. This led to the "False Suffocation Alarm theory" which posits that panic attacks and anxiety may derive from the dysfunction of a biological "CO2 sensor", evolutionarily designed to alert the organism in case of impending death by suffocation.
