RT @: Top climate scientist on monster tornadoes: ‘It’d be irresponsible not to mention climate change’

Throughout human history, the climate system has been a source of life and death, the sun and rain capable of feeding our crops and bringing us comfort, or unleashing terrible devastation in wind, fire, drought, storm, and flood. Each tragedy that occurs -- such as the terrible outbreak of tornadoes and flooding storms last week in the South -- reminds us of that awesome power, which is beyond our control and at the limits of our comprehension. We have also learned that humanity is meddling with that power, primarily through the burning of coal and oil that increases the amount of heat trapped in the atmosphere and oceans. Scientists have been warning our leaders for decades that this interference with the climate system is dangerous, and have worked tirelessly to explain how these threats are now coming to pass.

However, the Republican Party is now dominated by ideologues who deny the threat of polluting our climate, even when faced with direct evidence of what the climate system can do to the people they are sworn to protect.

Conservatives attack any discussion of climate policy within the context of the killer tornadoes as "grotesque," saying that to do so is blaming the victims.
