Dust from asteroids entering the atmosphere may influence Earth’s weather more than previously believed, according to an article in the journal Nature. Researchers have found evidence that dust from an asteroid burning up as it passed through Earth’s atmosphere formed a cloud of micron-sized particles large enough to influence local weather in Antarctica, where glaciers are rapidly melting. Particles this size are large enough to reflect sunlight, causing local cooling and playing a major role in cloud formation. The dust can even have a negative effect on the ozone layer. This may temporarily help reverse the rapid melting of the Antarctic.

As Hurricane Rita came ashore near Beaumont, Texas, it wasdowngraded to a tropical storm and continues to weaken as itmoves inland. The system is moving slowly and is expected todump upwards of 10 inches of rain across east Texas andLouisiana, with 5 or more inches in New Orleans.Nevertheless, early damage assessments suggest that there isextensive wind damage in many coastal communities. NewOrleans’ stricken 9th Ward is once again under 8 feet ofwater.

Do the recent hurricanes have anything to do with global warming? UK environmental head Sir John Lawton says this is what global warming looks like, when it starts to affect the world we live in.

Michael McCarthy reports in the Independent that climate change isn’t just a theory any more?it’s become a reality and we’re now paying the price for centuries of spewing greenhouse gases into the atmosphere. Hurricanes happen when the ocean surface gets warmer than normal?much warmer than the air above it. This is what turns an ordinary tropical storm, which is a storm on the ocean, into a hurricane. The damage starts when a hurricane blows moves onto land.

College and high school kids slug high caffeine coffee and soft drinks. But researchers have discovered that acupressure works even better.
