Vacuuming away CO2…

This might be useful down near Weyburn, where they’re using CO2 injection in the oilfields. The CO2 currently comes by pipeline from Beulah, North Dakota: …the new device captures carbon dioxide molecules that are already in the air and releases them as a pure carbon dioxide stream. This stream can be sequestered or used to …

And as long as I’m on the topic…

…here’s another interview with a German climatologist (one who very much agrees climate is changing and we’re largely responsible, before you ask) taking issue with the tone of the discussion: “We Have to Take Away People’s Fear of Climate Change.”

The debate about global warming "a mirage"?

That’s what three scientists, one from Denmark and two from Canada, say in a new paper: The entire debate about global warming is a mirage. The concept of ‘global temperature’ is thermodynamically as well as mathematically an impossibility, says professor at The Niels Bohr Institute, University of Copenhagen, Bjarne Andresen who has analyzed this hot …

Are we wrong about the causes of climate change?

There’s a legitimate rival theory about the most important thing driving climate change.

Maybe I’m just a contrarian, but…

…when people start preaching inevitable doom and gloom climate-wise due to global warming, it puts my back up. Yet, when people try to tell me there is no such thing as climate change, it annoys me just as much. Where’s a middle-of-the-road, yes-there’s-a-problem-but-it-ain’t-the-end-of-the-world-yet kind of guy to do? Turns out there’s a whole middle ground …

If Astana, Kazakhstan, can do it…

…why can’t Regina, Saskatchewan? Heck, if you squint, the two names are practically identical. “It,” in this case, is cover 100,000 square metres of downtown space with a giant, semi-transparent, climate-controlled tent. (Shades of the domed cities so beloved of old-time science fiction writers.) To whit: The Khan Shatyry entertainment centre in Astana will become …

Adapting to the cold

Every January, we residents of Saskatchewan ask ourselves the same question: why are we here, instead of in the tropics? There’s a scientific version of that same question: how have humans, who evolved in the tropics, managed to survive in the even-icier-than-Saskatchewan climes of the far north? The January 9 edition of the scientific journal …

Paleoclimatology

This week an international expedition set out for Mt. Logan, Canada’s highest mountain (and yes, it’s still Mt. Logan, not Mt. Trudeau) to attempt to travel through time: to look back 10,000 years to see how climate has changed over the millennia–and how human activities are affecting climate now.  Two Canadian scientists will climb to …

Floods

Seven years ago, it was the Mississippi. Three years ago, it was the Red River. Two years ago, the Yangtze River in China. This year, Mozambique. Recent years have seen a, well, a flood of devastating floods all around the world. And they’re getting worse. In 1998, total losses from weather-related natural disasters, including floods …

Global warming update

What with all the talk about the greenhouse effect recently, I decided it’s time for a quick review… The term “greenhouse effect” is usually used today in reference to a predicted gradual warming of the Earth caused by an increase in various gases in the atmosphere, primarily due to human activity. Really, however, the greenhouse …

Glaciers

The first time I saw Lake Louise, several years ago, its beauty stunned me. Recently I visited it again, and the effect was the same: if it’s not the most beautiful spot on Earth, it’s darn close. What created Lake Louise still hangs above it: a mighty glacier. A drive along the spine of the …

Melting ice in Antarctica

Considering how cold it’s been around here recently, global warming sounds not so much like an environmental problem as it does something devoutly to be wished for–but as someone once said, “Be careful what you wish for–you may get it.” While it’s true that science has yet to come flat out and say that global …
