How Unusual is a May Named Tropical Storm?

May or even April named tropical systems are actually not that uncommon, even when the Atlantic was cold as it was in the later 1960s and 1970s. The following shows the number of April/May (pre-offficial hurricane season) storms by decade from 1950s to the 2000s. Both the 1950s and 1970s had 3 early storms. We have had 2 so far this decade.

Does an early tropical system foretell an active season? Again history says no, at least not by itelf.  The average number of named storms that have occurred in years with an April or May storm since 1950 is 10.66, virtually the same as the average number for the season in all years during that period (1950-2006) of 10.72 storms. Actually more useful as a predictor is the warm Atlantic (positive Atlantic Multidecadal Oscillation) correlation that Bill Gray and Phil Klotzbach, Chris Landsea and those at the National Hurricane Center past (most recently Max Mayfield) and present adhere to. When the AMO is positive (the Atlantic is in its warm mode), the average since 1950 has been 12.81 storms.  It is in the warm mode this season.

Ironically Andrea’s formation brings to a close the longest period on record globally without a tropical cyclone. The last advisory issued on a tropical cyclone this year was at 06 GMT on April 6th, for Tropical Cyclone Cliff in the Southern Hemisphere. Wednesday’s 15 GMT advisory on Subtropical Storm Andrea ends the record longest period without a tropical cyclone at 33.4 days, besting the old record of 31.5 days set mid-April to mid-May in 1984. Reliable records of global tropical cyclone numbers go back to the beginning of the satellite era, about 1970.

Students Presented One Side of the Story

We hear in the news that many school systems around the country have made An inconvenient Truth required viewing for their students and in one system in California even the student’s parents. We know most students are being told in the classroom that the science is settled. This is true from the elementary to the college level. I have personally received e-mails from students at major universities seeking help finding more balanced information on climate change. They have told me their professors presented the science as indeed settled and no longer open for discussion, in more than one case calling skeptics shills for big oil or simply crackpots.

This story by Randy Hall of Cybercast News Service “ RI Students Must Watch ‘Inconvenient Truth’ to Graduate” is especially telling. 

To receive a degree from Roger Williams University in Rhode Island, students are being forced to watch “An Inconvenient Truth,” the documentary on global warming produced by former Vice President Al Gore. After learning of the requirement, Dana Peloso, an RWU junior and president of the school’s chapter of the College Republicans, sent a letter questioning the course requirement to Jeffrey Hughes, assistant dean of marine and natural sciences. “With the issue of global warming being such a highly politicized topic, with the scientific community unsure if global warming is man-induced or part of the natural cycle of the earth, do you think that it is intellectually honest to only show the alarmist viewpoint?” Peloso asked. “If the movie is still shown, what plans are there to incorporate the ideas of leading global warming skeptics into class discussion?” he added.

Assistant Dean Hughes replied “After an initial and heated debate, scientists no longer question whether the atmosphere is being warmed due to human activities and instead are increasingly impressed with the speed and impact of the process,” Hughes wrote. “I repeat: there is no doubt that we’re warming the earth and that a continuation of our activities will lead to profound changes.” “Penguins, polar bears and your unborn children have no vote in this. They must live with decisions we make today,” the assistant dean said.

The science class requirement has prompted one conservative student to declare that “we should stop calling these schools ‘bastions of knowledge’ since they’re really bastions of leftist thought.” Jason Mattera, who graduated from RWU in 2005, responded that Hughes’ behavior amounted to “gross intolerance” at a university that promotes itself as a place that values “collaboration of students and faculty in research” and “appreciation of global perspectives.”

NASA Discovers ‘Twilight Zone’ of New Air Particles

In a Live Science story, Andera Thompson reports on “An extensive and previously unknown “twilight zone” of particles in the atmosphere could complicate scientists’ efforts to determine how much the Earth’s climate will warm in the future.”

The area around clouds has given us trouble,” said study team member Lorraine Remer of NASA’s Goddard Space Flight Center in Greenbelt, Md. “The instruments detected something there, but it didn’t match our understanding of what a cloud or an aerosol looked like. What we think we’re seeing is a transitional zone where clouds are beginning to form or are dying away, and where humidity causes dry particles to absorb water and get bigger.” Scientists have been aware of an indistinct “halo” surrounding individual clouds, but the newly detected zone is much more extensive, taking up as much as 60 percent of the atmosphere previously labeled as cloud-free.

“The effects of this zone are not included in most computer models that estimate the impact of aerosols on climate,” said lead author Ilan Koren of the Weizmann Institute of Science, in Israel. “This could be one of the reasons why current measurements of this effect don’t match our model estimates.”

The study was published in the April 18 issue of the journal Geophysical Research Letters.

RMS and Great Global Warming Swindle

In the April 25th Icing the Hype story “Move Afoot to Block “The Great Global Warming Swindle “ DVD”, we reported about the effort of 37 UK scientists to block the sale of the DVD based on claimed inaccuracies and misrepresentations.

See Stephen McIntyre’s Climate Audit blog where he shows that at least three of their major claims are not justifed nor wise.  See Risk Management Solutions Ltd and the 37 Professors and RMS and Sulphate Emissions and Swindle and the Stick.

The Oceans Role in Greenland and the Arctic Region Temperatures and Ice

By Joe D’Aleo, Icecap

In the prior blog, we showed how multidecadal ocean cycles were playing a role in temperature swings over the past 110 years and could be used to explain much of the variance. In the attached brief paper, I show how the same can be said for Greenland and the Arctic where these factors play a far more convincing role in the observed changes than greenhouse gases.  This was confirmed in a June 2006 GRL paper Greenland Warming of 1920-1930 and 1995-2005 by Chylek etal.  See Greenland Warming

The Oceans Role in Climate Change

By Joe D’Aleo, Icecap

Dr William Gray has discussed the importance of the Atlantic Multidecadal Oscillation (AMO in both tropical storm activity and global warming.  Dr James Hansen et al., 1998 wrote about the importance of the Pacific Decadal Oscillation (PDO) in persisting regional patterns of coolness in the southeastern United States and warmth in the west.

In the following paper, I show how the oscillations in the two oceans affect temperature cycles and how irregular clustering of volcanic activity modulates the effects (enhancing or temporarily reversing). The numbers suggest the ocean multidecadal cycles are not given the respect they deserve in climate change.

Putting Popper in the Hopper

By Joe D’AIeo, Icecap

In his book Historical Perspectives on Climate Change, James Fleming noted that around 1950, the climatologist C. E. P. Brooks, echoing Rudyard Kipling’s “nine and sixty ways of making tribal lays,” quipped, “There are at least nine and sixty ways of constructing a theory of climatic change, and there is probably some truth in quite a number of them.”

That is as true today as it was half a century ago. Yet today, the media, the UN and many of the world’s governments have declared that only one is really important. Read More Popper_in_the_Hopper.pdf

Washington State Climatologists Battle over Snowpack Numbers

The Seattle Times reported last week “The snowpack in the Cascades, it was said, shrank by 50 percent in the last half-century. That statistic has been repeated in a government report, on environmental-advocacy web sites and in media coverage.... Seattle Mayor Greg Nickels recently mentioned it in a guest column in The Seattle Times....Here’s the problem. The number is dead wrong”. See how the debate caused the assistant state climatologist to be stripped of his title.

See in the analysis below how the changes are cyclical and likely relate to the PDO and not global warming. See Northwest_Snow_Drought?

Planetary Support for the Solar Influence in Climate Change

Warming on Neptune’s moon Triton, Jupiter, Pluto and Mars coincident with earth’s recent warming suggest the only common forcing, our sun, may to blame.

Note new paper also suggestive of correlations between the brightness of Neptune, solar variability, and Earth’s temperature Neptune Brightness Changes.
That paper was covered in World Climate report and indicated a correlation with solar irradiance of 0.90. See World Climate Report “Neptune News”

12 Step Pledge for All Climate Scientists

Across the globe, millions of people have been transformed by the values expressed within various 12 step self-improvement or recovery from addiction programs. ICECAP finds some of those principles relevant to the efforts to understand global climate change.

The climate change issue is highly polarized with scientists invested in one side of the issue or the other.  How about a similar kind of program for climate scientists? On Icecap, our scientists are willing to take such a pledge. We encourage all climate scientists to join us.

12 step program (code of ethics) for all climate scientists

- Admit that science is powerless, for now, to completely understand the world around us, and thus conclude that we can, from lack of objectivity, make our work unmanageable and misguide mankind.

- Admit that we can only partially measure the power of nature and how it brings balance to our environment.-

- Make a fearless inventory of any immoral motivations that may be interfering with the scientific method.

- Admit, when necessary, through this website and within all available media, our miscalculations.

- Trust, nonetheless, that these mistakes are to be celebrated as part of the process of true understanding and for a greater good.

- Humbly embrace all who will participate in the search for truth and never condemn or castigate those who differ with our conclusions.

- Make a list of all concerns about which we may have been misguided, while honestly and with humility and respect, updating them with current insight.

- Make direct and prompt contact with those that we may have inadvertently misguided, where possible and no further harm can occur.

- Take continuing intellectual inventory, and when we are wrong, promptly admit it.

- Through inner counsel and personal integrity, humbly submit to a methodology that allows for a true understanding of nature’s wonder.

- Having trained ourselves to understand nature with sensitivity, reverence and rigorous scientific inquiry, encourage all of humanity to share in our wonder and respect for the world around us.

IPCC Wrong again: Studies Find Extreme Cold kills more than extreme heat

On Friday, April 6, the Intergovernmental Panel on Climate Change (IPCC) will release a report detailing the projected impacts of global warming. This report has been called the heart and soul of the issue. It will provide detail as to what the Panel believes will be the result of their global warming projections. I am sure one of the items mentioned will be increased deaths due to heat waves. I’ll bet what is not mentioned is that the number of deaths in the United States due to extreme cold is greater than the number due to extreme heat. See Craig’s blog here
