Real Climate Science

1994 was a cold year, due largely to the eruption of Mt. Pinatubo. That year also had  a lot of Arctic ice. There was a similar polar vortex cold outbreak during that year, and no one was stupid enough to blame it on global warming.

Technology to Cool the Planet: An Interview with David Keith

Boston Review: First, can you explain to readers why sulfates are good candidates for geoengineering, as opposed to other molecules?

David Keith: Sulfates are the devil we know. Small water droplets would be roughly as effective as sulfuric acid in reflecting sunlight—clouds, composed of water droplets, are white and reflective—but they would evaporate almost instantly in the dry air of the stratosphere. The sulfuric acid keeps the water from evaporating.

Sulfur emissions from fossil fuel combustion are already cooling the planet and killing roughly a million people a year from air pollution worldwide. The amount of sulfur that would need to be put in the stratosphere for solar geoengineering would be a few percent of current fossil fuel emissions. Any such injection would carry real environmental risks such as ozone destruction and acid rain, but sulfates have the advantage of being a common atmospheric chemical, one that is injected into the stratosphere by volcanic eruptions. So although sulfates are risky, we have some empirical evidence about what the risks are.

01 Apr 1990 – EARTHWEEK: A DIARY OF THE PLANET Global Warming

Twenty-four years later, NASA and NOAA ignore the more accurate satellite data – and report only useless, tampered surface temperatures.

Measured January temperatures for Minnesota show no trend since 1895, with the current month being the second coldest on record.

No trend means no global warming funding, so NOAA cools the past at 1.9ºF/century.

In 1974, Time Magazine blamed the cold polar vortex on global cooling.

Scientists have found other indications of global cooling. For one thing there has been a noticeable expansion of the great belt of dry, high-altitude polar winds —the so-called circumpolar vortex—that sweep from west to east around the top and bottom of the world.

Forty years later, Time Magazine blames the cold polar vortex on global warming

But not only does the cold spell not disprove climate change, it may well be that global warming could be making the occasional bout of extreme cold weather in the U.S. even more likely. Right now much of the U.S. is in the grip of a polar vortex, which is pretty much what it sounds like: a whirlwind of extremely cold, extremely dense air that forms near the poles. Usually the fast winds in the vortex—which can top 100 mph (161 k/h)—keep that cold air locked up in the Arctic. But when the winds weaken, the vortex can begin to wobble like a drunk on his fourth martini, and the Arctic air can escape and spill southward, bringing Arctic weather with it. In this case, nearly the entire polar vortex has tumbled southward, leading to record-breaking cold

At least the 1974 version made sense. Bryan Walsh’s 2014 version makes a complete farce out of science.

Snowfalls are now just a thing of the past

Monday 20 March 2000

the warming is so far manifesting itself more in winters which are less cold than in much hotter summers. According to Dr David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia,within a few years winter snowfall will become “a very rare and exciting event”.  “Children just aren’t going to know what snow is,” he said

US is having record cold at the solar maximum, with ENSO neutral and no large volcanic eruptions for 20 years.

So what happens at solar minimum, La Nina and the next Pinatubo?
