U.S. Lightning Strikes May Increase 50% Due to Global Warming
By: Dr. Jeff Masters
Published: 14 novembre 2014
A warmer world will have much more dangerous cloud-to-ground lightning capable of igniting more forest fires, according to a study published Thursday in the Journal Science. The research found that for each degree Centigrade of global warming, lightning in the U.S. is expected to increase by 12%, resulting in about a 50% increase in lightning by the year 2100.

Stunning and welcome climate change news came out of China on Tuesday, when President Obama and Chinese President Xi Jinping announced a historic joint climate commitment. The U.S. pledged to cut greenhouse gas emissions by 26 - 28% by 2025, compared with 2005 levels. In turn, China agreed to peak its greenhouse gas emissions by 2030, and to get 20% of its energy from non-fossil fuel sources by 2030.
IPCC Final Report: We've Blown Two-Thirds of Our Carbon Budget

Published: 2 novembre 2014
"Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems", said the Nobel Prize-winning Intergovernmental Panel on Climate Change (IPCC) today, in the final installment of their once-every-seven-year report on the climate.
Wunderground's Climate Change Position
Based on the evidence, more than 97% of climate scientists have concluded that human-caused climate change is happening. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.

October 2014: Earth's Third Consecutive Warmest Month on Record

October 2014 was the warmest October on record, and the year-to-date-period January - October was Earth's warmest such period since record keeping began in 1880, said NOAA. They also rated the past 12 months--November 2013 through October 2014--as the warmest consecutive 12-month period among all months since records began in 1880; 2014 will be the warmest calendar year on record if global temperatures in November and December merely match their average values recorded since 2000.
