Late season snowfalls vs CO2 levels

As I said in the last post, the level of 350ppm is (according to scientists such as Bill McKibben), the upper safe level of this GHG.

Dr Masters talks abut the recent nor-easter, and talks about late season snowfall in general.

He also links to a post by weather historian Christopher C. Burt, in which late season storms are mentioned.

So, from that post:

"...World-record Snowfalls During April

World Record 24-hour Snowfall at Silver Lake, Colorado

The greatest 24-hour snowfall officially measured in the world was the 75.8” that fell at Silver Lake, Colorado (in the mountains just west of Boulder) on April 14-15, 1921. The storm total was an amazing 95.0” over a 32½ hour period..."

*** Now the really important stuff. CO2 level then was at 303.7ppm. Weather that severe in April with lower levels than today. Strange, isn't it? ***

Next:

"...World-record Single Greatest Snowfall in the Sierra Nevada

The greatest single-storm snowfall on record in the world was 194” (over 16 feet!) that fell during a massive spring blizzard at the Sierra Nevada railway summit station of Norden over the four day period of April 20-23, 1880. Sacramento, California’s capital city, received a record two-day rainfall of 8.37” during this event..."

*** Again, looking at the data: CO2 levels in 1880 were at 290.8. CO2 for March 2012 was at 394.45, so that was 103.65ppm less than today. It's simply staggering that such severe weather can occur with such amazingly low levels of the most potent GHG ever, CO2.

There's one more, proving it's global:

"...World-record 19-hour Snowfall and European Record

Europe’s greatest 24-hour snowfall happened at Bessans in the French Alps on April 5-6, 1959 when 67.8” accumulated in just 19 hours (a world record for a 19 hour period)..."

*** Well, a little closer to present times, but still, in 1959, we were below the upper safe limit of CO2: 316.18.

I, for one, can't wait for the world to get back down below the magic level of 350ppm - thereby saving us from the extreme weather we've been seeing. Take me back to the severe weather of old...

Keeping this here for next update:

"...An unprecedented April heat wave brought a second day of sizzling temperatures to the Western U.S. yesterday, where temperatures ranging 20 - 30 degrees above normal have toppled numerous all-time April heat records. Nearly every weather station in the Inter-mountain West has broken, tied, or come within 1 - 2 °F of their all-time record April heat record since Sunday. Most notably, the 113°F measured at Furnace Creek in Death Valley, California on Sunday, April 22 was tied for the hottest April temperature ever recorded in the U.S. According to wunderground weather historian Christopher C. Burt, the hottest reliable April temperature ever measured in the U.S. was 113°F in Parker, Arizona in 1898..."

CO2 level for yesterday's 113 degree reading, 394.45.

CO2 level for the 1898 113 degree reading, 294.9.

Just another example that weather happens, and heat (or snow) is not necessarily driven by higher levels of CO2. One end of the country, unprecedented levels of extreme snowfall, caused by CO2. The other end of the country had unprecedented levels of extreme heat - again, driven by unprecedented levels of CO2.

And yet, we've seen examples of the same extreme weather when CO2 was MUCH LOWER THAN TODAY.

Coonnect the dots. What do both yesterday's extreme heat and the 1898 extreme heat have in common? Not much. One was weather, the other CAGW.
