The article “Unknown Plague Killing Sea Stars on West Coast” (June 30) reported that there is evidence of temperature sensitivity related to the die-off of sea stars along the West Coast.

With frequent examples of a changing climate popping up in the news, people who care about our progeny should start lining up now at the Federal Building in Pittsburgh for the July 31 U.S. Environmental Protection Agency hearing on carbon dioxide limits for power plants.

The 21st century has simply been hotter than the 20th. We are at an 800,000-year high for carbon dioxide levels in our atmosphere.

Finally, claims that President Barack Obama has waged a war on coal jobs are simply wrong. According to eia.gov/​coal/​annual/, in 2002 Pennsylvania employed 7,663 coal miners and hovered around the mid-7,000s for much of the George W. Bush administration. Pennsylvania employed 8,927 coal miners in 2012, 300 more than the year before. So an increase in jobs has occurred during the Obama administration.
