Dairy farming is predicted to lose up to 20 percent of its production by 2100 because of the effect of heat stress on cows. Crop yields have the potential to decrease by as much as 39 percent.
Our black cherry trees are in danger of losing their habitat. This loss would affect our timber and furniture-making industries.
In the past decade flooding caused $441.5 million in damage in southeastern Pennsylvania. In June 2006, severe flooding caused hundreds of thousands of people to evacuate regions of eastern Pennsylvania. Three thousand three hundred flood insurance claims were filed. An estimated $30 million worth of property damage occurred in Bucks County alone. In 2004 millions of dollars in damage was realized when more than 30,000 homes and businesses in western Pennsylvania were damaged by flooding from Hurricane Ivan.
Greater numbers of intense rainfalls and tornadoes are expected as temperatures rise.
Our signature maple/beech/birch forests are predicted to disappear by the end of the century. Our famed fall foliage displays, which attract annual tourists, will will go with them. Ecosystems and life forms in those forests will be forever altered, affecting our hunting industry.
Warmer weather means less snow for the ski industry. The Pennsylvania Ski Areas Association (PSAA) has realized the threat to its industry and is working to make changes and educate the public. Fewer cold water fisheries means that industry will suffer too. Predicted diminished stream and river flows and lower lake levels, particularly in drought-ridden summers, won't help the situation.
According to the Pennsylvania Fish and Boat Commission, recreational fishing has major positive economic impacts for Pennsylvania. Its overall contribution is conservatively estimated at $1.35 billion per year. It supports nearly 17,000 jobs and adds nearly $50 million per year to the Commonwealth's General Fund in the form of sales and income taxes. Global warming will significantly cut into those numbers.
The Stern Review on the Economics of Climate Change (2006) estimated that if we do nothing, global warming will cost the world at least five percent and as much as 20 percent of its Gross Domestic Product (GDP).
Numerous studies have concluded that a 25 percent by 2025 requirement for renewable energy is affordable, achievable and, most importantly, will create hundreds of thousands of clean energy jobs in every region of the U.S. A 2009 study by the Union of Concerned Scientists concluded 297,000 jobs in manufacturing, construction, operations, maintenance, agriculture, forestry and many other industries would be created.
A long-term commitment to renewable energy is critical to the global competitiveness of U.S. renewable energy component manufacturing and development. Without a strong national renewable electricity standard (RES), many states will actually lose clean energy jobs.
