Colorado Snowpack is 654% of normal

Wow. Perpetual drought predictions are not coming true.

As the days get warmer, the snowcaps in the High Country are about to shrink. An epic spring runoff is in the works after one of the best winters in recent years, and local water and emergency officials are preparing Summit County for the deluge.

Snowpack across the state is 654% of normal, according to the latest snow survey from the National Resources Conservation Service. That is 51 times larger than the state’s average snowpack at this time last year, with flooding a much bigger concern at this point than wildfire. The state of Colorado is drought-free for the first time in 20 years, according to the U.S. Drought Monitor.

So Much For Tree Rings As A Temperature Proxy

So much for tree rings as a temperature proxy.

Huge Canadian Tree Growth Study.

Our analyses of a new methodologically standardized tree-ring dataset covering Canada’s boreal forest provide insights into the growth responses of this ecosystem to climate change. Although revealing no overarching “growth enhancement” or “growth decline” in recent years, results do point to significant regional- and species-related trends in growth. The observed link between climate variation and growth variability revealed unique evidence of an intensification of the impacts of hydroclimatic variability on growth late in the 20th century, in parallel with the rapid rise of summer temperature.

Such response can be attributed to annual growth variability in these forests being mainly driven by negative sensitivity to summer temperature (warmer summers leading to less growth) and positive sensitivity to summer soil moisture (more moisture leading to more growth)


Sixteen Natural Droughts Since 1658 Worse Than Todays

Tree rings are magical. Not only can you reconstruct temperatures from the past, but you can reconstruct droughts (rainfall).

Whenever I see the word “novel approach” I worry we are in for BS.

However, since the authors of this paper are saying things were worse in the past than present I like to pretend I believe them.

They also sort of say that more dendrohydrologists are needed. Surprise.

Recent streamflow droughts in south coastal British Columbia have had major socioeconomic and ecological impacts. Increasing drought severity under projected climate change poses serious water management challenges, particularly in the small coastal watersheds that serve as primary water sources for most communities in the region. A 332-year dendrohydrological record of regionalized mean summer streamflow for four watersheds is analyzed to place recent drought magnitudes in a long-term perspective.

We present a novel approach for optimizing tree-ring based reconstructions in small watersheds in temperate environments, combining winter snow depth and summer drought sensitive proxies as model predictors. The reconstruction model, estimated by regression of observed flows on Tsuga mertensiana ring-width variables and a tree-ring derived paleorecord of the Palmer Drought Severity Index, explains 64% of the regionalized streamflow variance.

The model is particularly accurate at estimating lowest flow events, and provides the strongest annually resolved paleohydrological record in British Columbia. The extended record suggests that since 1658 sixteen natural droughts have occurred that were more extreme than any within the instrumental period. Flow-duration curves show more severe worst-case scenario droughts and a higher probability of those droughts in the long-term reconstruction than in the hydrometric data.

Such curves also highlight the value of dendrohydrology for probabilistic drought assessment. Our results suggest current water management strategies based on worst-case scenarios from historical gauge data likely underestimate the potential magnitudes of natural droughts. If the low-flow magnitudes anticipated under climate change co-occur with lowest possible natural flows, streamflow drought severities in small watersheds in south coastal British Columbia could exceed any of those experienced in the past ∼350 years.


Study: No Difference Between 20th-century Rainfall Patterns and Those in the Pre-­Industrial Era

What a shocker. The climate cycles keep going up and down and so-called global warming” doesn’t change it

Predictions that a warmer ­climate will lead to more rain for some but longer droughts for others might be wrong, according to a study of 12 centuries worth of data.

The study, published today in science journal Nature, found there was no difference between 20th-century rainfall patterns and those in the pre-­industrial era. The findings are at odds with earlier studies suggesting climate­ change causes dry areas to become drier and wet areas to become wetter.

Fredrik Ljungqvist and colleagues at Stockholm University analysed previously published records of rain, drought, tree rings, marine sediment and ice cores, each spanning at least the past millennium across the northern hemisphere.

They found that the ninth to 11th and the 20th centuries were comparatively wet and the 12th to 19th centuries were drier, a finding that generally accords with earlier model simulations covering the years 850 to 2005.

However, their reconstruction “does not support the tendency in simulations of the 20th century for wet regions to get wetter and dry regions to get drier in a warmer climate”.

Our reconstruction reveals that prominent seesaw patterns of alternating moisture regimes observed in instrumental data across the Mediterranean, western USA and China have operated consistently over the past 12 centuries,” the paper says.

California Water Management Fails Epically

Michael Reagan states the obvious:
In response to the shortage of water, the California Water Resources Board wants to institute a punitive fine of $500/day for people it calls “water hogs.”
But I think Thomas Del Beccaro, writing in Forbes, has a better idea: Let’s fine the board for failing to do its job over the last 40 years.
He explains, “California is the most populated state in the Union, with more than 38 million people. Its population was just under 20 million in 1970, when the bulk of its current water storage and delivery systems were already built. In other words, the California governments have done very little to significantly increase water supplies in over 40 years, even though its population has doubled during that period of time.
Instead of realizing that “water” was its middle name, the board has been made captive by enviro-Nazis who think people in general are the enemy. Rather than build dams and reservoirs to keep up with a growing population, state government has preferred to depend on the kindness of clouds to provide water for taxpayers.
Then the clouds stopped being kind.
Felicia Marcus, chairman of the water board, exemplifies the arrogant, buck-passing mentality of its members: “I like to say, having a browning lawn and a dirty car is a badge of honor.”
No Felicia, the dead grass and filthy car are the result of a do-nothing board that should be thrown out on its ear.

California February 2014 – Almost 6 Times As Much Rain Compared to January

Update: I had 2013 in the title. Sorry. (thanks justsoeguy31167)

According to the NOAA, California averaged 3.43 inches of rain in February 2014, which was only .42 inches below the 1901-2000 mean.

That is about 5.7X as much rain compared to January when California only averaged only .6 inches of rain.

One month of average rainfall won’t end a drought, but it sure helps.


Climate Change Caused Never Ending Drought in California … oops. Nevermind.

Climate Change Caused a never ending drought In California … except for the never ending part.

“The storm – the largest since 2010”

“This is no drought-buster, but it’s a nice, fat down payment” in the water bank, he said.”

“As of Saturday evening, the storm had dropped more than 4 inches of rain in downtown Los Angeles, 5 inches in Van Nuys and almost 12 inches at Cogswell Dam in the Angeles National Forest, according to the National Weather Service.”

Rainfall over the last month has helped facilitate the salmon’s return to their spawning grounds, said the local water district officials who track their numbers.”

“Ski resorts were delighted with fresh snow that promised to extend their season

WAIT … I thought the end of snow was here because of climate change?

But my  favorite quotation is: “The storm wasn’t all bad news, though.

Bad News!!!!!!!!!!!!  Rain in a drought is now BAD NEWS???????????

Why is rain bad news? Because it spoils the climate change con game. In a few weeks the AGW Cult will be complaining about too much rain and how climate change causes floods.

Whatever The Cause – Blame Global Warming – So Says The NY Times

The NY Times is beclowning itself again in this article on drought in California.

Despite the fact that a cool PDO and warm AMO brings drought to California as shown by this post (referencing an article by Roger Pielke Sr. from 2012).

“What may be different about this drought is that, whatever the cause, the effects appear to have been made worse by climatic warming. And in making that case last week, scientists said, the administration was on solid ground.”


What clowns.

October 2012 Precipitation NOAA

No state broke a record for driest October in 2012 according to the NOAA.

Texas came closest to a record with its 9th driest October at .83 inches. It will be hard to break the 1952 record of .02 inches.

New Mexico had very little rain during its 14th driest October. The record from 1952 was 0 so it can only be tied.

Delaware did break a record for wettest October ever.

15 states have 1952 as the driest October,  12 have 1963 and 6 are from 1924.

A rank of 1 = driest. A rank of 118 = wettest.
