New model better represents the effect of global climate patterns on the Amazon basin
El Niño–Southern Oscillation (ENSO) cycles strongly influence the interannual variability of climate, weather patterns, and streamflow in South America's Amazon basin.
Solar wind enhancements cause auroral pulsations
Ultralow-frequency (ULF) radio waves, observed in the magnetosphere and used for secure military communications, can be disturbed and compressed by aurora and geomagnetic storms.
Trends in sea ice thicknesses point to future ice-free summers for the North Pole
In September of 2007, sea ice in the Arctic Ocean had a minimum monthly extent of 4.26 × 106 km2, 23% lower than the previous minimum in 2005. Is this drastic reduction the result of natural variability superimposed on a general declining trend, or is Arctic sea ice cover shifting into a different climatic state characterized by completely ice-free summers?
