Global warming in California

06/05/2011

“Spring passed California by, and summer remains in hiding.  …

A giant Sierra snowpack, still frozen fast, has put innumerable summer adventures on hold.  …

And it’s not over yet: Sacramento can expect as much as another 1.4 inches of rain this weekend and temperatures 20 degrees below normal, with more mountain snow.  …

One theory gaining traction is that climate change, in fact, may be to blame.

The theory was developed in several published papers by Judah Cohen, an atmospheric scientist in Massachusetts.  …

Colder and snowier winters caused by global warming? It may be one of the counterintuitive consequences of climate change, he said.

“We don’t understand everything, and we don’t understand how the different feedbacks affect different parts of the climate system,” said Cohen, director of seasonal forecasting at Atmospheric and Environmental Research, a private firm in Lexington, Mass. “It’s very complicated. So we should expect the unexpected.”  …

“The cooler weather is just not allowing the plants to grow like they should be,” [Jean Miller, assistant agricultural commissioner in Glenn County] said. “We have the possibility for diseases which we would not normally be having at this time of year, when it should be 80 or 90 degrees.”  …

The statewide snowpack stands at 262 percent of average. Rather than shrinking, as it normally would by this date, the snowpack has held steady and even grown deeper in places with new storms.  …

The state’s reservoirs are brim-full, yet the snowpack still has to melt. This could lead to flooding problems, especially on the San Joaquin and Kings rivers, said Rob Hartman, hydrologist-in-charge at the California-Nevada River Forecast Center, a branch of the National Weather Service.

The peak of spring snowmelt, Hartman said, is probably now delayed to late June or early July – at least a full month late.”  “Researcher says climate change may be cooling California

DOI issues new model-based alarmist report

04/26/2011

“Secretary of the Interior Ken Salazar today released a report that assesses climate change risks and how these risks could impact water operations, hydropower, flood control, and fish and wildlife in the western United States. The report to Congress, prepared by Interior’s Bureau of Reclamation, represents the first consistent and coordinated assessment of risks to future water supplies across eight major Reclamation river basins, including the Colorado, Rio Grande and Missouri river basins.  …

The report, which responds to requirements under the SECURE Water Act of 2009, shows several increased risks to western United States water resources during the 21st century. Specific projections include:

  • a temperature increase of 5-7 degrees Fahrenheit;
  • a precipitation increase over the northwestern and north-central portions of the western United States and a decrease over the southwestern and south-central areas;
  • a decrease for almost all of the April 1st snowpack, a standard benchmark measurement used to project river basin runoff; and
  • an 8 to 20 percent decrease in average annual stream flow in several river basins, including the Colorado, the Rio Grande, and the San Joaquin.  …

To develop the report, Reclamation used original research and a literature synthesis of existing peer-reviewed studies. Projections of future temperature and precipitation are based on multiple climate models and various projections of future greenhouse gas emissions, technological advancements, and global population estimates.”  “Interior Releases Report Highlighting Impacts of Climate Change to Western Water Resources

AGW causes everything

02/12/2010

Lack of snow in warm Vancouver is evidence of AGW.  Record snowfall in cold Washington DC is evidence of AGW.  Ho hum.

“Let’s compare DC’s actual temps with normal temps for those days.

Date     Normal Avg. DC Temp.    Actual Average DC Temp

Dec. 18        39                                    30.8
Dec. 19        39                                    26.3
Feb. 5          36                                    34.8
Feb. 6          36                                    27.4
Feb. 10        37                                    25.9

Normal average temp: 37.40
Actual average temp: 29.04

Bottom line: the temperature was colder than average on every one of the snow days.  On average the snow days were about eight degrees colder than average.

To spin these facts as proof that the blizzards are evidence of global warming because “warm air holds more moisture” is bunk.

Will the MSM note this little analysis?”  “Blizzard of Lies: Debunking The Warm-Air-Holds-More-Moisture Defense

“Washington Governor Gregoire recently sent a letter to the Washington House delegation in which she stated that the snow pack has declined 20% over the past 30 years: “Last month, a study released by the University of Washington shows we’ve already lost 20% of our snow pack over the last 30 years.” Actual snow pack numbers show a 22% INCREASE in snow pack over the past 33 years across the Washington and Oregon Cascade Mountains.” “Pacific Northwest Snow Pack – the True Story

Willis Eschenbach on negative feedback and "The Thermostat Hypothesis"

06/28/2009

Abstract

The Thermostat Hypothesis is that tropical clouds and thunderstorms actively regulate the temperature of the earth. This keeps the earth at a equilibrium temperature.

Several kinds of evidence are presented to establish and elucidate the Thermostat Hypothesis – historical temperature stability of the Earth, theoretical considerations, satellite photos, and a description of the equilibrium mechanism. …

Conclusions and Musings

1. The sun puts out more than enough energy to totally roast the earth. It is kept from doing so by the clouds reflecting about a third of the sun’s energy back to space. As near as we can tell, this system of cloud formation to limit temperature rises has never failed.

2. This reflective shield of clouds forms in the tropics in response to increasing temperature.

3. As tropical temperatures continue to rise, the reflective shield is assisted by the formation of independent heat engines called thunderstorms. These cool the surface in a host of ways, move heat aloft, and convert heat to work.

4. Like cumulus clouds, thunderstorms also form in response to increasing temperature.

5. Because they are temperature driven, as tropical temperatures rise, tropical thunderstorms and cumulus production increase. These combine to regulate and limit the temperature rise. When tropical temperatures are cool, tropical skies clear and the earth rapidly warms. But when the tropics heat up, cumulus and cumulonimbus put a limit on the warming. This system keeps the earth within a fairly narrow band of temperatures.

6. The earth’s temperature regulation system is based on the unchanging physics of wind, water, and cloud.

7. This is a reasonable explanation for how the temperature of the earth has stayed so stable (or more recently, bi-stable as glacial and interglacial) for hundreds of millions of years.” “The Thermostat Hypothesis
