3. The government’s newest national assessment of climate change declares that increased global warming is affecting every part of the United States.
The report released Tuesday cites wide and severe impacts: more sea-level rise, flooding, storm surges, precipitation and heat waves in the Northeast; frequent water shortages and hurricanes in the Southeast and the Caribbean; and more drought and wildfires in the Southwest.
“For a long time, we have perceived climate change as an issue that’s distant, affecting just polar bears or something that matters to our kids,” said Katharine Hayhoe, a Texas Tech University professor and a co-author of the report. “This shows it’s not just in the future; it matters today. Many people are feeling the effects.”
The federal climate assessment — the third since 2000 — brought together hundreds of experts in academia and government to guide U.S. policy based on the best available climate science.
The authors of the more-than-800-page report said it aims to present “actionable science” and a road map for local leaders and average citizens to mitigate carbon and other gas emissions that warm the planet.
But the report ran immediately afoul of conservative critics who called it a political document, aimed at giving President Obama a leg up on regulating major polluters such as power plants. In their opinion, regulation costs jobs. Obama, who is increasingly focusing on climate change, spent part of the day talking about the report with television meteorologists from across the country.
