Many vertebrate species (that category includes us) would have to evolve about 10,000 times faster than they have in the past to adapt to the rapid climate change expected in the next 100 years.

Scientists analyzed how quickly species adapted to different climates in the past, using data from 540 living species from all major groups of terrestrial vertebrates, including amphibians, reptiles, birds and mammals. They then compared their rates of evolution to rates of climate change projected for the end of this century.

While most of the world is experiencing global warming, Alaska seems to be entering another ice age. Since 2000, temperatures in Alaska have dropped by 2.4 degrees Fahrenheit. When scientists looked at weather reports from 20 climate stations in that state that are operated by the National Weather Service, 19 of the 20 of them reported FALLING temperatures.

Musicians treasure the small number of Stradivarius violins that were made in the small area of Cremona, Italy in the 17th century. Modern manufacturers have struggled in vain to make instruments that have the same musical qualities. Now a tree-ring dating expert and a climatologist have discovered the secret of the Stradivarius.

Henri Grissino-Mayer and Lloyd Burckle say the “Little Ice Age” in Europe, which lasted from the mid-1400s until the mid-1800s, produced long winters and cool summers that slowed down tree growth, making the wood used for the violins incredibly dense.

Ice ages may occur when our Solar System passes through thespiral arms of the Milky Way during our orbit around thecenter of the galaxy. Dr. Nir Shaviv of the University ofToronto has found evidence linking changes in the cosmicrays reaching the Earth and the times that ice ages occurredin the past.

He believes that the cosmic rays come from stars thatexplode as the Earth exits one of the Milky Way’s spiralarms. The increased cosmic rays then trigger ice ages on Earth.If this is true, we won?t have another ice age for tens ofmillions of years, since our Solar System is not due toleave another spiral arm for a very long time.
