Scientists counter climate change skeptic
Paula Jasinski knows the science behind climate change isn’t bulletproof.
Yet she thinks there is overwhelming evidence that mankind — not Mother Nature — is chiefly responsible for increasing temperatures that are causing sea levels to rise and other changes to the planet.

Her opinion matches that of most climate scientists, who argue that power plants, motor vehicles and other conveyances are polluting Earth’s atmosphere and causing the planet to warm.
It contrasts with former NASA scientist Roy W. Spencer, who suggested to several hundred conference attendees on Tuesday that rising temperatures are part of Earth’s natural cycle. Spencer was invited to speak by Gov. Bob McDonnell’s administration, which is fighting federal efforts to counteract global warming.
