Supernaturally Green - Warming Trend Coming
"April prepares her green traffic light and the world thinks Go" mused Christopher Morley. I love this time of year - the landscape bursting out in a carpet of bright, almost urgent lime-green.
Before the inevitable onslaught of giant bugs, sputtering severe thunderstorms and drippy dew point recitations. So much promise.
Yes, Cinderella, it's still cool out there, but you could argue that the weather is "just right"; too warm for slush, too cool for angry supercell thunderstorms. And with El Nino fading into a mild La Nina cooling phase the risk of debilitating summer drought is small.
The sun makes a cameo appearance today (upper 50s will feel surprisingly good) before the next southern storm brushes the metro area with rain Saturday PM. Sunday will be the drier, better day to trim the lawn.
ECMWF (European) guidance shows a steady warming trend next week with a streak of 60s and 70s. 80 degrees isn't out of the question by next Friday with June-like humidity levels; a few strong T-storms a week from Sunday?
I may have to take off my shirt and annoy the neighbors.
January 22-23, 2016 Blizzard Now Thought To Be Biggest Snowfall on Record for New York City. Nearly 18" fell in Washington D.C. - for NYC it was a legitimate record-setter. Here's an excerpt of a review from NOAA: "...The preliminary Central Park measurement will be adjusted upward to 27.5 inches, which will become an all-time snowfall record for New York City when certified by NOAA’s National Centers for Environmental Information. A communication error between the weather forecast office in Upton, New York, and the Central Park Conservancy, which volunteers to take official snow measurements in Central Park, led to an inaccurate preliminary total of 26.8 inches. The snow team found the mistake when reviewing the Conservancy’s logbook..."
The Worst-Case Scenario: How To Ride Out a Tornado. Here's an excerpt of a good, timely post at al.com: "...The best place to ride out a tornado is in a storm shelter, or the smallest room in the center of the building you'€™re in on the lowest floor, such as a closet or bathroom, interior hall or under a stairwell. Get away from windows. Get under something that can protect you from flying debris, which is the greatest danger in tornadoes, according to NOAA'€™s Storm Prediction Center. Cover yourself with a mattress or sleeping bag. Know where the heavy things are on the floors above you and don't get under them. Get as low to the floor as you can and cover your head with your hands..."

Nothing to Sneeze At: More CO2 = More Pollen. Here's an excerpt of a story at Climate Central: "...In a previous report, we illustrated how ragweed pollen production increases with CO2 levels. New research continues to shed light on the relationship between pollen and climate change. While ragweed studies give one example of how pollen is impacted by higher levels of CO2, other plants have also been subsequently examined. In this report, we highlight a new study that looks at Timothy Grass pollen, a major cause of allergies during the early summer. Researchers investigated the amount of pollen produced at CO2 concentrations of 400 ppm, which is near current levels, and 800 ppm, which we would pass before the end of the century if current emissions trends continue. Not surprisingly, the grass produced about twice as much pollen at 800 ppm..."

The King of Frequent Flier Miles? Quora has an interesting post - not feeling nearly as good about my 900K with Delta: "I'm going to have to go with Fred Finn, with 15 million miles, to include 718 Concorde flights—logging three crossings in a day once. Being a British citizen, he's evidently garnered more miles with British Airways than any other, but I can't find all of the airlines—139 countries is a lot and must mean lots of other airlines—nor if BA has a majority of the impressive total."

Climate Change Could Threaten Trillions of Dollars of Financial Assets, a New Study Reports. Here's the intro to a story at PRI, Public Radio International: "New research from the London School of Economics estimates that a broad range of global stocks and other financial assets are overvalued because investment managers don’t take the risks of climate change into account. The LSE research estimates financial assets worldwide are presently overvalued by $2.5 trillion — and, in the worst case, $24 trillion. Massive climate-related writedowns are not far off in the future, which would mean huge losses for investors who ignore the risks, says Alex Bowen of the Grantham Research Institute on Climate Change at LSE and co-author of the new study, published in Nature Climate Change..."

- An increasing number of registered voters think global warming is happening. Three in four (73%, up 7 points since Spring 2014) now think it is happening. Large majorities of Democrats—liberal (95%) and moderate/conservative (80%)—think it is happening, as do three in four Independents (74%, up 15 points since Spring 2014) and the majority of liberal/moderate Republicans (71%, up 10 points).
- By contrast, only 47% of conservative Republicans think global warming is happening. Importantly, however, there has been a large increase in the number of conservative Republicans who think global warming is happening. In fact, conservative Republicans have experienced the largest shift of any group—an increase of 19 percentage points over the past two years....

The Political Hurdles Facing a Carbon Tax - And How To Overcome Them. How do you adequately factor (real) costs into the equation? Dave Roberts has an interesting post at Vox; here's a clip: "...The point is, carbon prices, where they exist, are too low. Why? The obvious answer is that carbon pricing faces various political constraints, which prevent the carbon price from rising to the proper (high) level. Unfortunately, these political constraints are not nearly as well-understood as the economic dynamics of carbon pricing. Among climate economists and wonks, the hunches, pet theories, and ritual invocations of "political will" too often are substitutes for deeper, systemic political analysis. The Jenkins-Karplus paper is an attempt to make some progress on that score. It sets out to model carbon pricing scenarios, seeking to determine which policy design leads to the greatest aggregate social welfare under various political constraints..."

“It is assumed that the major contributors of CO2 are the burning of fossil fuels… There is no doubt that increases in fossil fuel usage and decreases of forest cover are aggravating the potential problem of increased CO2 in the atmosphere. Technology exists to remove CO2 from stack gases but removal of only 50% of the CO2 would double the cost of power generation.” [emphasis added]Those lines appeared in a 1980 report, “Review of Environmental Protection Activities for 1978-1979,” produced by Imperial Oil, Exxon’s Canadian subsidiary..."
