What Does the Pope’s Climate Encyclical Mean?

Pope Francis released his much-anticipated encyclical on humans’ stewardship of our planet earlier today. While my colleagues and I spend most of our time talking about science and policy, the pope’s message has given us an opportunity to reflect on our own moral reasoning around climate and energy issues as well as the intersection of faith and science.

Update, June 23: My colleague Mike Jacobs, a senior energy analyst, added his thoughts in a separate post about Pope Francis’s plug for electric co-cops and other clean energy issues in the encyclical. Read More

Was There No Global Warming Slowdown? A New Paper Challenges the Theory

NOAA scientists released a study last week in Science magazine detailing how new updates on observations show there has been no global warming slowdown.

In science we are always looking for more data to validate results. It is a bit like being a detective: the more information you have, the better the case. For global warming it is meteorological stations overland and buoys and ship data over the ocean. Read More

Land-Sector Actions in U.S. Climate Policy—and at the UNFCCC

In early April I wrote a blog post on the U.S. INDC (“Intended Nationally Determined Contribution”) which was submitted to the UN Framework Convention on Climate Change (UNFCCC). I focused on how it treated the land sector (agriculture and forests). In mid-April this analysis, along with similar consideration of the INDCs of Mexico and the European Union, was written up in a White Paper, and a few days ago we presented the results of this White Paper at a UNFCCC side event in Bonn.

Later in April, U.S. Secretary of Agriculture Tom Vilsack and Senior Presidential Advisor Brian Deese announced the Department of Agriculture’s Building Blocks for Climate Smart Agriculture and Forestry. In this blog post I’ll describe those building blocks, as well as the elements of the President’s Climate Action Plan (released in June 2013) that relate to the land sector.

Jeb Bush on Climate Change: What Do We Really Want Politicians to Debate?

Former Florida Governor Jeb Bush (R) described the certainty of scientific knowledge on climate change as “convoluted” yesterday. Specifically, he said that it’s unclear “what percentage is man-made and what percentage is natural.”

He also claimed that people who say the science is “decided on” are “arrogant.” Read More

CNN Just Went a Full Year without Debating the Reality of Climate Change

It’s been exactly a year since CNN hosted a misleading debate about established climate science. I hope it was the last one for the network and that CNN and other news outlets can move on to debates about how society is responding to climate risks. Read More

Dear Humans: Industry is Causing Global Warming, Not Your Activities

Scientists and climate policy wonks usually say global warming is caused by “human activities.” This shorthand obscures an important point: while we humans are certainly responsible for climate change on some level, just a few of us – particularly in industry and government – are a lot more responsible than the rest of us.

After all, I like humans. I like activities, too. And it’s industry practices and government policies that largely determine how much heat-trapping emissions our human activities produce. Read More

Forests, Agriculture, and Climate Change: Why the U.S. Needs Action, Not Just Accounting, in its INDC

The United States has now told the world what it intends to do about climate change in the 2020s, by submitting its INDC (“Intended Nationally Determined Contribution”) to the United Nations. As we found in our report Halfway There? in January, the U.S.’ land sector – agriculture and forests – could be a big deal for the climate negotiations in Paris next December. Of course, our actions to reduce fossil fuels will be critical, but land use is important both as a source of global warming pollution and a way to take it back out of the atmosphere. Read More

Testifying about Sustainability and the American Diet

The day before yesterday, together with my UCS colleagues Lindsey Haynes-Maslow and Deborah Bailin, I went to the National Institutes of Health to testify on the Scientific Report of the 2015 Dietary Guidelines Advisory Committee. This report, prepared by a committee of experts every five years, provides the basic information for federal food programs such as school lunches and SNAP (formerly called food stamps), and is used to create the official U.S. Dietary Guidelines that are the basis for the MyPlate graphics.

Lindsey, Deborah and I testified about different aspects of the DGAC report, and they have already put their testimony up on their blogs. Here is mine, which focuses on food sustainability issues such as the climate impacts of the American diet.

Making Room for Renewables: Grid Integration Solutions for California’s Clean Energy Future

I’ve blogged many times about the clean energy policies California has in place that have made it a leader. The state is well on its way to supplying 33 percent of its electricity from renewable sources by 2020 and now, in a visionary step to dramatically reduce global warming emissions, is considering ways to increase that amount to 50 percent by 2030.

Book Review: How Culture Shapes the Climate Change Debate by Andrew Hoffman

A few years ago, my colleagues and I worked with Andrew Hoffman, the director of the Erb Institute for Global Sustainable Enterprise at the University of Michigan, to host a forum on increasing public understanding of climate change. The event sticks with me because the participants came from so many different backgrounds: environmental justice, Creation care, energy production, social science, media, climate science, and service in Congress.

Hoffman has condensed the myriad approaches to climate communication we discussed that day — and much more — into an indispensable guide. At a slim 100 pages, Hoffman’s book offers a fine distillation of the growing body of social science that explains our curious and conflicting approaches to climate issues. In addition to identifying the problematic ways we often approach climate change, he also suggests several potential ways forward that can restore the climate debate to what he calls a “more civilized plane.” Read More
