Today we’re releasing an important report on what the world’s largest emitters of greenhouse gases could do to reduce the global warming pollution released by their land sectors—that is, their agriculture and forests. It’s called Halfway There? What the Land Sector Can Contribute to Closing the Emissions Gap.

On Wednesday, the Obama Administration announced a new goal and course of action to cut methane emissions from the oil and gas industry by 40-45 percent from 2012 levels by 2025. It’s a sensible near-term target that helps address one of the most potent contributors to global warming. But will the measures the Administration plans to implement be enough to achieve the goal?

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.

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.”

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.

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

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
