By analyzing observations and results obtained from climate models, a new study has shown that previously rare high summertime (June, July and August) temperatures are already occurring more frequently in some regions of the 48 contiguous United States.

That figure represents an increased vulnerability from population and especially economic growth, as well as the effects of climate change.

The fears were soon quieted: the radiation doesn't reach Earth, though it can affect satellites and humans moving through the belts. Nevertheless, many mysteries about the belts -- now known as the Van Allen Radiation belts -- remain to this day.

The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow.

These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). While these are the most common solar events, the sun can also emit streams of very fast protons -- known as solar energetic particle (SEP) events -- and disturbances in the solar wind known as corotating interaction regions (CIRs). All of these can produce a variety of "storms" on Earth that can -- if strong enough -- interfere with short wave radio communications, GPS signals, and Earth's power grid, among other things.

A new study examining weather patterns around the time of these pandemics finds that each of them was preceded by La Niña conditions in the equatorial Pacific. Since the La Niña pattern is known to alter the migratory patterns of birds, the scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.

Millions of livestock died in Mongolia and the re-introduced wild Przewalski's horse population crashed dramatically.

But recent work may help this balance through a project that alerts control room operators of wind conditions and energy forecasts so they can make well-informed scheduling decisions. This is especially important during extreme events, such as ramps, when there is a sharp increase or decrease in the wind speed over a short period of time, which leads to a large rise or fall in the amount of power generated.

But all the same, he'd opt next time for a handmade torture chamber. "Some people will complain about the heat, but from my viewpoint as a breeder, I love stress," said a rose breeder.

This can in turn drive global warming by reducing the amount of carbon dioxide removed from the atmosphere by trees and by releasing carbon locked up in their wood. New research offers evidence for the physiological mechanism governing tree death in a drought.

Both events seem to be linked to a relatively rare coupling between the polar and the subtropical jet streams.
