Pfft, we could use the heat up here. It's been ridiculously cold here all year.

You bring Al "The Hypocrite" Gore here to Minnesota and we'll hang his arse for telling us it was going to get warmer when it's not.

Another recent and important tool
 in understanding some of the remaining questions (SUN-Solar System)) 
 (Launch 02/11/2010).
 
 
 
 
 

About The SDO Mission

SDO: The Solar Dynamics Observatory is the first mission to be launched for NASA's Living With a Star (LWS) Program, a program designed to understand the causes of solar variability and its impacts on Earth. SDO is designed to help us understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

SDO's goal is to understand, driving towards a predictive capability, the solar variations that influence life on Earth and humanity's technological systems by determining

  • how the Sun's magnetic field is generated and structured
  • how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in the solar irradiance.

SDO Science

SDO will help us to understand the how and why of the Sun's magnetic changes. It will determine how the magnetic field is generated and structured, and how the stored magnetic energy is released into the heliosphere and geospace. SDO data and analysis will also help us develop the ability to predict the solar variations that influence life on Earth and humanity's technological systems.

SDO will measure the properties of the Sun and solar activity. There are few types of measurements but many of them will be taken. For example, the surface velocity is measured by HMI. This data can be used for many different studies. One is the surface rotation rate, which must be removed to study the others. After subtracting the rotation, you have the oscillation and convective velocities. The latter look like billows of storm clouds covering the Sun. Hot gas moves outward at the center of the billows and downward at the edges, just like boiling water. By looking at these velocities you can see how sunspots affect the convection zone. By looking at a long sequence of data (more than 30 days), you see the oscillations of the Sun (like the picture). These patterns can be used to look into and through the Sun.

Mission Science Objectives
The scientific goals of the SDO Project are to improve our understanding of seven science questions:
  1. What mechanisms drive the quasi-periodic 11-year cycle of solar activity?
  2. How is active region magnetic flux synthesized, concentrated, and dispersed across the solar surface?
  3. How does magnetic reconnection on small scales reorganize the large-scale field topology and current systems and how significant is it in heating the corona and accelerating the solar wind?
  4. Where do the observed variations in the Sun's EUV spectral irradiance arise, and how do they relate to the magnetic activity cycles?
  5. What magnetic field configurations lead to the CMEs, filament eruptions, and flares that produce energetic particles and radiation?
  6. Can the structure and dynamics of the solar wind near Earth be determined from the magnetic field configuration and atmospheric structure near the solar surface?
  7. When will activity occur, and is it possible to make accurate and reliable forecasts of space weather and climate?

SDO Instruments

SDO contains a suite of instruments that will provide observations leading to a more complete understanding of the solar dynamics that drive variability in the Earth's environment. This set of instruments will:

  1. Measure the extreme ultraviolet spectral irradiance of the Sun at a rapid cadence
  2. Measure the Doppler shifts due to oscillation velocities over the entire visible disk
  3. Make high-resolution measurements of the longitudinal and vector magnetic field over the entire visible disk
  4. Make images of the chromosphere and inner corona at several temperatures at a rapid cadence
  5. Make those measurements over a significant portion of a solar cycle to capture the solar variations that may exist in different time periods of a solar cycle

The Science Teams will receive the data from SDO. They will process, analyze, archive, and serve the data.

HMI (Helioseismic and Magnetic Imager)
The Helioseismic and Magnetic Imager will extend the capabilities of the SOHO/MDI instrument with continual full-disk coverage at higher spatial resolution. PI: Phil Scherrer, PI Institution: Stanford University.
AIA (Atmospheric Imaging Assembly)
The Atmospheric Imaging Assembly will image the solar atmosphere in multiple wavelengths to link changes in the surface to interior changes. Data will include images of the Sun in 10 wavelengths every 10 seconds. PI: Alan Title, PI Institution: Lockheed Martin Solar Astrophysics Laboratory.
EVE (Extreme Ultraviolet Variablity Experiment)
The Extreme Ultraviolet Variablity Experiment will measure the solar extreme-ultraviolet (EUV) irradiance with unprecedented spectral resolution, temporal cadence, and precision. Measures the solar extreme ultraviolet (EUV) spectral irradiance to understand variations on the timescales which influence Earth's climate and near-Earth space. PI: Tom Woods, PI Institution: University of Colorado.

Image Resolution Comparison

The following image illustrates the resolution capabilities of the SDO, STEREO, and SOHO spacecrafts. SDO's AIA instrument (right image) will have 1/2 greater image resolution than STEREO (middle image) and 3/4 greater imaging resolution than SOHO (left image). The image cadience also varies. SDO takes 1 image every .10 of a second. At best STEREO takes 1 image every 3 minutes and SOHO takes 1 image every 12 minutes.

3-2-1 and Liftoff of GOES-P!
The Delta IV carrying GOES-P lifted off at 6:57 p.m. EST from Launch Complex 37B at Cape Canaveral Air Force Station in Florida.

After reaching orbit, GOES-P will become GOES-15. The satellite will be used to monitor and predict weather, measure ocean temperatures, perform climate studies, and detect hazards with its emergency beacon support and Search and Rescue Transponder.

GOES-P was built by Boeing for NASA and the National Oceanic and Atmospheric Administration, or NOAA.

Geostationary Operational Environmental Satellite-P, or GOES-P, is the latest in a series of meteorological satellites designed to watch for storm development and weather conditions on Earth. From its location in Earth orbit, GOES-P's state-of-the-art instrumentation will supply data used in weather monitoring, forecasting and warnings. It also will detect ocean and land temperatures, monitor space weather, relay communications and provide search-and-rescue support.

Nasa's Solar & Heliospheric Observatory (SOHO) captures a rare solar event.

_________________________________________________________________

 

CME Lashes Out

STEREO (Ahead) watched as a strong coronal mass ejection (CME) and an eruptive prominence rose up and stretched way out above the Sun's surface (Feb. 28, 2010). The composite image and movie show the action in both extreme UV wavelength (orange Sun) near and just above the solar surface overlaid on the frames from STEREO COR1 coronagraph that shows the material as it rises out into the corona. The video clip shows about 8 hours of activity. This is one of the brightest and most substantial CMEs we have seen in several years. And the presence of such bright prominence material in COR1 is very rare and has only been seen twice before.

Whats going on with the planets oceans
Low Oxygen levels creating (Dead Zones), quickly becoming more acidic, and losing salinity.
 
Short Video on the Northwest (USA)
 
 
Interview with Oregon State University (Jack Barth)
 
_______________________________________________________________________
Growing low-oxygen zones in oceans worry scientists
 
By Les Blumenthal, McClatchy Newspapers Les Blumenthal, Mcclatchy Newspapers Sun Mar 7, 12:01 pm ET

WASHINGTON � Lower levels of oxygen in the Earth's oceans, particularly off the United States' Pacific Northwest coast, could be another sign of fundamental changes linked to global climate change, scientists say.

They warn that the oceans' complex undersea ecosystems and fragile food chains could be disrupted.

In some spots off Washington state and Oregon , the almost complete absence of oxygen has left piles of Dungeness crab carcasses littering the ocean floor, killed off 25-year-old sea stars, crippled colonies of sea anemones and produced mats of potentially noxious bacteria that thrive in such conditions.

Areas of hypoxia, or low oxygen, have long existed in the deep ocean. These areas � in the Pacific, Atlantic and Indian oceans � appear to be spreading, however, covering more square miles, creeping toward the surface and in some places, such as the Pacific Northwest , encroaching on the continental shelf within sight of the coastline.

"The depletion of oxygen levels in all three oceans is striking," said Gregory Johnson , an oceanographer with the National Oceanic and Atmospheric Administration in Seattle .

In some spots, such as off the Southern California coast, oxygen levels have dropped roughly 20 percent over the past 25 years. Elsewhere, scientists say, oxygen levels might have declined by one-third over 50 years.

"The real surprise is how this has become the new norm," said Jack Barth , an oceanography professor at Oregon State University . "We are seeing it year after year."

Barth and others say the changes are consistent with current climate-change models. Previous studies have found that the oceans are becoming more acidic as they absorb more carbon dioxide and other greenhouse gases.

"If the Earth continues to warm, the expectation is we will have lower and lower oxygen levels," said Francis Chan , a marine researcher at Oregon State .

TG
The weather has been wacky here as well, we have gotten more rain in first 2 months of this year than the entire previous year (2009).
 
the Desert is green (Literally), we dont see this very often. It is quite the sight, a brown to black environment converted into a blanket of green. I need to get out and take some pictures.

Recent Greenland ice loss responsible for one sixth of sea-level rise

van%20de%20broeke%20Greenland%20ice%20loss

Between 2000 and 2008, Greenland lost 1500 cubic kilometres of ice, which is responsible for one-sixth of global sea-level rise, says scientists.

Michiel van den Broeke of Utrecht University in the Netherlands and colleagues say that the bad news is that the rate of ice loss is increasing.

To reach the conclusion, researchers began by modelling the difference in annual snowfall and snowmelt in Greenland between 2003 and 2008 to reveal the net ice loss for each year. They then compared each year's loss with that calculated from readings by the GRACE satellite, which "weighs" the ice sheet by measuring its gravity.

The researchers found that results from the two methods roughly matched and showed that Greenland is losing enough ice to contribute on average 0.46 millimetres per year to global sea-level rise.

The loss may be accelerating: since 2006, warm summers have caused levels to rise by 0.75 millimetres per year, though van den Broeke says we can't be sure whether this trend will continue.

Sea levels are rising globally by 3 millimetres on average.

The researchers said that half the ice was lost through melting and half through glaciers sliding faster into the oceans.

"The study gives us a really good handle on how to approximate how much ice Greenland is going to lose in the coming century," New Scientist quoted Ted Scambos of the US National Snow and Ice Data Center in Boulder, Colorado, as saying.

No no no, bring out cap and trade!

Let's seal the deal and kick the Dems out of office for the foreseeable future. The Dems think they've taken a pounding over healthcare? Just wait for them to unveil the largest, economy destroying tax hike in world history! Nothing like $4 a gallon gasoline to get the people screaming for blood!

TG & 4=Laro
 
Whats your answer then?   Do Nothing
 
TG we have already had $4.00 gas and we will get there again and even more with or without cap and trade if we do not chaange our mindset on Oil.
 
I know how bout we give a tax break to people who buy this
Estimated at over 200 MPG, which sounds like fuzzy math but even if it ends up at a 100mpg is a significant improvement.  Due out November 2010
File:2011%20Chevrolet%20Volt%20--%202010%20DC.jpg
 
Instead of like Bush giving Tax Break for buying this
10 to 14 MPG

I thought we need $7.00 a gallon gasoline to reduce CO2 emissions? Oh, wait a minute it's not about reducing CO2 emissions, it's about further taxation and repressions! Why do I say repressions, because I won't be able to afford the $10,000 airfare to fly my family to Kauai in the future.
