In early December of 2017, a jet stream brought an very large surge of cold air to the Deep South and northern Gulf of Mexico. A widespread dusting of snow to a couple centimeters blanketed much of the Florida panhandle and upper parts of the states peninsula. Amazing amounts of snow and ice hit northern Florida, last week, as this National Weather Service map shows. What is more surprising about this winters Florida snow is how warm it is supposed to be in Orlando at this time of year 71 degrees. Savannah's previous snow record was set 28 years ago.
Scientists are studying cloud seeding, a method that aims to boost how much rain or snow falls from the sky. Dry ice, falling on the cloud, caused submicroscopic bits of ice to appear in the cloud, Science News reported in January 1947. Cloud seeding might work, but not for every cloud in every place. The SNOWIE project used this and another plane to study cloud seeding from inside clouds. In their experiment, SNOWIE scientists would seed a portion of a cloud from one aircraft.
On November 19, NOAA reported that the previous months average temperature across Earth's land and oceans was the highest for any October in 135.8 years. Even small temperature increases can cause big changes in places where the weather is near the temperature at which water freezes. A warming climate also increases the area where certain infectious diseases might occur. Vector, borne diseases, crop failure, coastal erosion and heat stress are all serious threats related to climate change and global warming. There are things people and governments can do to make themselves better able to tackle climate change.
Sweltering summer heat waves are on the rise across the Northern Hemisphere. Scientists spotted a decline in the strength of summer storms. Wind pattern changes brought on by the rapidly warming Arctic weakened summer storms. The researchers described their findings online March 13 in Science. Fewer storms boost the risk that summers in the Northern Hemisphere will become dangerously warm.
