Out of $1.4 billion on table, House cuts $542,000 for NOAA climate website

On Tuesday, the U.S. House of Representatives voted on, among other things, NOAA's fiscal year 2013 budget proposal. Of a possible $1.4 billion dollars in proposed spending cuts in the Departments of Commerce and Justice, the only thing the House of Representatives cut was a drop in the bucket: $542,000 for NOAA's climate portal website.
When Students Listen: Atlantic Multi-decadal Oscillation

As it stands in my mind today, the variability in the North Atlantic temperature behavior is strongly influenced by aerosols in the atmosphere and a trend due to increasing carbon dioxide. If there is oscillatory behavior in the temperature, it is due to increases and decreases in atmospheric aerosols, perhaps on top of a smaller atmospheric-oceanic dynamic variation that still requires explanation. A good step forward, I think.

On Saturday, May 5, the activist group 350.org, founded by Bill McKibben, launched a new effort to "connect the dots between climate change and extreme weather." They declared May 5 Climate Impacts Day, and coordinated an impressive global effort of nearly 1,000 events in 100 countries to draw attention to the links between climate change and extreme weather.
Wunderground's Climate Change Position
Earth's climate is warming. This time, humans are mostly responsible, and the overwhelming majority of climate scientists agree. The warming climate is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. There are economically sensible steps we can take to lessen the damage—the cost of inaction is much higher than the cost of action.
