Amazon Deforestation in Brazil: New Numbers, Better Understanding

The new annual data on Amazon deforestation in Brazil has just come out, and it’s good news. For the latest year—August 2013 through July 2014—the annual total was 4,848 square kilometers. That’s 18 percent less than in the previous year, and the second-lowest figure ever. Read More

How to Talk About Climate Change at Thanksgiving: Recipes for Good Conversations

My mother’s family is politically diverse. And opinionated. As my grandmother tells it, the last time she and my grandfather voted for the same president was Eisenhower. Like a lot of families, our discussions around the holidays can veer into national issues and politics. Sometimes those discussions are enlightening, but they can also devolve into arguments.

2014 on Track to be Hottest Year on Record

Today, NOAA announced another startling record-breaking month of elevated global temperatures. We have just experienced the  hottest October since record keeping began 135 years ago. This year, May, June, August, September and now October – half the months so far – all smashed previous records for global land and ocean temperatures.

According to NOAA, “The January–October combined global land and ocean average surface temperature was the warmest such period on record, surpassing the previous record set in 1998 and 2010.”

Out of Facts, Climate Contrarians Seek to Intimidate

Last week, my colleague Dr. Brenda Ekwurzel gave a talk alongside Dr. Michael Mann, a Penn State professor who has faced constant harassment from politicians and groups that don’t accept mainstream climate science.

The event received an outsize amount of scrutiny from climate contrarians, including some misleading and forceful demands directed at Dr. Mann and the event organizers. Read More

Six Candidates, Three Debates, ZERO Arguments About Climate Science

There was a slight thaw in the climate change debate this month. Six candidates for high office – three Republicans and three Democrats – publicly debated what to do about climate change instead of arguing about the science. Read More

Who’ll Plant the Trees for Our Grandchildren to Use?

Thinking about trees often makes you think about your grandchildren. Both start small, can live for many decades, and will grow old in a world very different from ours today. And they’re connected. I expect that my granddaughter Esme, who just turned 1 ½, will probably live in a house made of wood, will write on paper, and perhaps will keep her house warm in the winter, as my wife and I do, with a wood stove. Have we thought about what trees that wood will come from? Read More

Charles Mann and The Atlantic Miss The Mark in a Confused Climate Change Piece

A recent climate change article by Charles C. Mann in The Atlantic left me scratching my head. The title, “How to Talk About Climate Change So People Will Listen” piqued my interest. It’s something I grapple with every day. But instead of focusing on how our public conversations about climate change are shifting, he lingers on what he sees as failed efforts to enact national climate policy. Mann is a serious and respected writer — who happens to work with some of my favorite magazines — so this piece felt like a missed opportunity. Read More

Hot Models Try to Forecast CO2 Reductions

A hot chase over models began soon after the Environmental Protection Agency (EPA) released draft CO2 rules June 2. Reducing CO2 (carbon-dioxide, the climate-altering pollution) in the electricity sector is not a mystery, but expecting too much from a model can be frustrating. With the CO2 rules, we have entered a new era, triggering a great clamoring amongst policymakers and advocates to get comfortable with the models. Temperatures are rising, and it is not just the hot summer weather. Read More

CNN’s Climate Coverage Shows Signs of Improvement

Earlier this year, we released an analysis that examined cable news climate coverage from the top three networks. In 2013, CNN aired inaccurate statements about the science in 30 percent of its climate-change-related segments. Such misleading statements usually took place during debates about established science. Guests, including politicians and commentators, also made inaccurate statements about climate science that often went unchallenged. Read More
