Atmospheric Warming and the Changes in El Nino Patterns Tampering with the global thermostat by injecting more greenhouse gases into the air will likely interfere with the traditional El Nino process. El Ni o events. Masks Warming Changes in the Pacific Ocean are making it more likely that winter weather in much of the United States will exhibit unusual warmth alternating with sharp cold. Researchers said the pattern, prevalent this winter and last, might predominate for 20 or 30 years. The biggest global warming in the last 100 million years may have been touched off by a sudden blowout of greenhouse gases from the ocean floor.
Scientists worry about a new eruption of seabed methane.
The great ice cover that stretches across the top of the globe has become about 40 percent thinner than it was two to four decades ago, scientists have found after analyzing data collected by nuclear submarines plying the Arctic Ocean. The findings, according to a commentary, should be interpreted as a warning that a regional shut-down of convection could occur, and occur soon. Louisiana Coast Coastal Louisiana is literally sinking into the sea, giving the rest of North America an alarming glimpse of what may lie in store in the 21st century. Since 1930, an area 50 percent bigger than Rhode Island has returned to the sea in Louisiana and another Rhode Island-sized patch could go in the next 50 years. Than Expected Rising global temperatures are impacting ocean ecosystems to a far greater extent than previously acknowledged.
