  1. ICE UPDATE JUNE 2008. THIS YEARS ICE DEPTH AND TOTAL ICE SURFACE IS 25% GREATER THEN LAST YEAR JUNE 2007.WINDS ALOFT ARE NORMAL AND TOTAL SUNSHINE TO DATE IS 50 % LESS THEN LAST YEAR AT THIS TIME.THE REAL TEST WILL BE IN AUGUST WHEN SEA ICE BEGINS TO THIN OUT AROUND THE BEARING SEA.AT THIS TIME LAST YEAR THERE WERE SOME WATER HOLES AROUND THE WEB CAMS. THIS YEAR THERE ARE NONE TO BE FOUND BUT THE ICE IS THINNING OUT FAST AROUND ( Tuktoyaktuk ) AND ALONG THE COAST COMPARED TO LAST YEAR.
  2. I will only give updates on dome A temps once a week or if i see that any cold fronts that are important that may drop the temp to near record values i will post it.
  3. We are at a point soon where we will start to see some water ponds forming in about 10 days.
  4. Tornados, Flooding May Warn Of Climate Change (Jun. 4, 2008) Record-keeping meteorologists at the National Oceanographic and Atmospheric Administration say this years tornado season is one of the deadliest in a decade and may be on pace to set a record for the most tornadoes. And flooding in the Midwest has been at 100-year levels this spring. There is considerable concern that climate change due to greenhouse gases species increasing will lead to the enhancement of strong, large storms occurrences, such as hurricanes that also spawn tornadoes when they occur. Increased storm strengths also bring flooding events, he said. Gaffney and co-researcher Nancy A. Marley are currently involved in a three-year investigation of aerosols tiny particles suspended in the air and their role in climate change.* Tornadoes are short-lived events and, until recently, scientists had to depend on limited ground observations to study them. Satellites and radar systems are now enhancing researchers ability to see their number and strength in detail. But short lived tornadoes are hard to tie directly to climate change due to the limited climatology of tornadoes. Weather forecasters have examined El Niño and La Niña, important temperature fluctuations in surface waters of the tropical eastern Pacific Ocean, as a potential for past tornado activities in the U.S. The data available from NOAA do not support a strong statistical significance to data for direct effects of El Niño or La Niña on frequency or strength of tornadoes, Gaffney said. Although, there is considerable concern that climate change due to greenhouse species will lead to significant changes in weather patterns, these currently available data are not conclusive. He said the Intergovernmental Panel on Climate Changes report on severe weather events discusses the topics backed up by NOAA data. Basic thought is theres more energy in the atmosphere, more water vapor evaporating and greater likelihood for stronger heating events that lead to stronger thunderstorms - super cells, that can lead to tornado production, Gaffney said. He said tornadoes are complex phenomena that are linked to the number of super cells and their storm strengths. Flooding events are more wide spread than tornadoes, and are more readily tied to climate predictions than tornadoes. What we are looking to see, in current and future research and data acquisition, is whether the frequency and strength of tornadoes change as we continue to increase the energy distribution in the atmosphere, he said. Currently, this year is looking to be significantly larger in the number of tornadoes seen than in the past few years. That and the record floods that are associated with these strong storm systems, may be a warning of things to come. But more data gathering is needed. Gaffney points to the improved Doppler radar systems that have allowed tornado warning times to be advanced as the main tool for gathering this tornado climatology that will be needed to evaluate links between climate change and severe weather events. *The $625,000 study is funded by the Department of Energy Atmospheric Science Program. He and Marley will discuss severe weather and links to climate during their annual orientation for the DOE Global Change Education Program. APA

  6. The National Snow and Ice Data Center has just released their latest update (month of May) on the sea ice situation up in the Arctic. Here are some of the main highlights from their report..... Arctic sea-ice situation --Sea ice extent is below the long-term average. --Sea ice extent is very close to the low levels seen in May 2007. (May 2008 extent was 0.11 million sq. miles greater than May 2007). --Spring ice cover is thin. --The average decline rate this May was 3000 sq. miles per day faster than May 2007. --The average Arctic Ocean surface air temperatures in May were 1 to 3 degrees celsius (2 to 5 degrees F) above normal. --Thin ice that covers the Arctic Ocean is showing signs of early breakup. --There is a distinct lack of thick, resilient multi-year ice, but the thin ice is farther north than normal, which may make it less vunerable than if it was in its normal position.
  7. PRECIP FORCAST FOR SUMMER 2008 (BRETT ACCUWEATHER ) The second map below shows what I expect for summer precipitation. Keep in mind summer precipitation can vary greatly over short distances due to the convective (showers/t-storms) nature of precipitation. The neon green color indicates above-normal rainfall, the base green color indicates near-normal, while the yellow/brown color shows where I expect the summer to be drier than normal.
  8. 2008 SUMMER FORCAST ( BRETT FROM ACCUWEATHER ) After sorting through global land and ocean data, long range models and past climate I have finally come up with a summer 2008 forecast for Canada. Some of the more key things that I have considered....... --A fading La Nina --A cool phase of the PDO (Pacific Decadal Oscillation) --Much of the North Atlantic having above-normal sea-surface temperatures. --Cooler-than- normal Pacific waters from the Gulf of Alaska to the U.S. West coast and off of Baja (part of the cool phase PDO) --Drier-than-normal ground southern prairies. --I expect a more active Atlantic tropical storm/hurricane season with a greater than normal threat to Atlantic Canada, especially in late- August and September. --The mean position of the U.S. high Plains ridge of high pressure will allow a greater than normal amount of thunderstorm complexes to track from the central Plains to the Great Lakes as they run along the "rim of the ridge" The top map shows my prediction for temperatures across Canada for the summer as a whole. The red areas are above normal, green near normal and blue is below normal.
  9. METEO MARS SOL 1 meteo mars pour le 27 Mai 2008. Skies were clear and sunny on Sol 1 on Mars. The temperature varied between minus 80 degrees in the early morning and minus 30 C degrees in the afternoon. The average pressure was 8.55 millibars, which is less than a 1/100th of the sea level pressure on Earth. The weather station was activated in the first hour after landing on Mars. Measurements are being recorded continuously. The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver. The Canadian Space Agency contributed Phoenix's meteorological station. The University of Aarhus in Denmark contributed the telltale on the meteorology mast.

  11. Is This The Last Barrier to a Climate Collapse? Dr. Tim Flannery, an Australian global warming activist, mammalogist and palaeontologist has proposed a radical solution to slow down global warming, which in his words is the last barrier to a climate collapse, according to The Age. Flannery say's climate change is happening so quickly that mankind may need to pump sulphur into the upper atmosphere in order to survive. His technique places sulphur gas into the earth's stratosphere to block out more of the sun's rays. How would this be done? Sulphur would be added to jet fuel and dispersed in the stratosphere. When should this happen? Flannery says we may need to be doing this in five years time. This process would also cause the sky to change color. But what color? Yellow? According to Flannery, the world was much more susceptible to greenhouse gas emissions that had been thought eight years ago. "Regardless of what happened to emissions in the future, there was already far too much greenhouse gas in the atmosphere," he said. "Cutting emissions was not enough. Mankind now has to take greenhouse gases out of the air," he added. In particular, carbon should be taken out of the air and converted into charcoal, then plowed into farmers' fields. Flannery was named Australian of the year for 2007. AP
