Why University Research Is More Important Than Ever

A dangerous ideological current is coursing through the intellectual circuit, a political conviction dressed up as an empirical theory. Its proponents argue that public funding of basic scientific research is, at best, a waste of money and, at worst, an actively counterproductive endeavor that crowds out the private sector’s innovative instincts. And the institutions in the crosshairs of these broadsides are U.S. research universities, the country’s most valuable assets in a global economy driven by innovation. Read more »

Five Things I Learned About the Future of Solar Power and the Electricity Grid

Nestled in the foothills of the Rockies in Golden, Colorado, the Energy Department’s  National Renewable Energy Laboratory (NREL) was established in 1977 to help bring new energy technologies to market. Today it is one of seventeen national laboratories overseen by the Energy Department and the only one whose sole focus is renewable energy and energy efficiency research and development. I spent a full day touring the facilities and interviewing researchers working on a range of solar photovoltaic (PV) technologies and on integration of clean energy into the electricity grids of the future. Here’s what I learned: Read more »

To Succeed, Solar Perovskites Need to Escape the Ivory Tower

What will tomorrow’s solar panels look like? This week, along with colleagues from Oxford and MIT, I published a feature in Scientific American making the case for cheap and colorful solar coatings derived from a new class of solar materials: perovskites. In this post, I’ll critically examine prospects for commercialization of solar perovskites, building on our article’s claim that this technology could represent a significant improvement over current silicon solar panels. We argue: Read more »

Keystone, Science, and Politics

by Michael Levi

Jeff Tollefson has an excellent new piece in Nature exploring the debate within the scientific community over Keystone XL. It makes two things pretty clear. As a matter of substance, there’s pretty much no one beyond Jim Hansen willing to come close to endorsing the “game over” claim. Yet there’s still a ton division among scientists – it’s over political tactics instead. Ken Caldeira captures the situation well: “I don’t believe that whether the pipeline is built or not will have any detectable climate effect,” he tells Nature. Nonetheless, here’s his bottom line: “The Obama administration needs to signal whether we are going to move toward zero-emission energy systems or whether we are going to move forward with last century’s energy system”. That sort of sentiment is political– and there’s nothing wrong with it – but, as the Nature article nicely shows, it’s distinct from any scientific debate. Read more »

What the Higgs Boson Tells Us About Climate Skeptics

by Michael Levi

Scientists around the world are celebrating the discovery of the Higgs boson. Last December, researchers announced that they might have glimpsed the elusive particle, but refrained from declaring victory, since there was a one percent chance that their result was a fluke. Now they’re confident: the odds of error in the new calculations are less than one in three million. Read more »

Yellow Flags On A New Methane Study

by Michael Levi

A forthcoming paper in the influential Journal of Geophysical Research has measured concentrations of methane and other alkanes in air near oil and gas operations in Weld County, Colorado, and has used that to infer rates of methane leakage from natural gas production in the region. Their results, which were reported last week by Nature and the Associated Press, point to much higher methane emissions than consensus inventories have previously found. Indeed some have read the results as confirming the highly controversial estimates of methane leakage published last year by Cornell professor Robert Howarth and his colleagues. Read more »

An Important Report on Climate and Extreme Events

by Michael Levi

The IPCC has issued a special report on “Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation” (SREX). It’s an immensely useful document. Those of us whose research focuses on policy responses to climate change are bombarded daily with new studies that claim to have established that this or that cataclysmic outcome (devastating drought, mass species extinction, hurricanes galore) is a virtual certainty. But I’ve picked through too much bad climate-related work, including in top journals like Science and Nature, to simply accept every peer reviewed paper on faith. Indeed while these studies are often compelling, it’s difficult to separate those that are genuinely solid from ones that rest on less stable ground. That’s why institutions like the IPCC, and reports like this new one, are so valuable. Read more »

The Climategate Dud

by Michael Levi

Like most other climate change observers, I’ve been pretty convinced that “Climategate” – the publication of stolen e-mails from the University of East Anglia that showed climate scientists in an ugly light – has been a big contributor to American doubts about climate change. And those doubts are big: In a post earlier today, my colleague Jim Lindsay (bookmark his new blog on the domestic politics of U.S. foreign policy) flags an October Pew poll that showed only 59% of Americans believing that the earth is warming, and only 34% believing that warming is due to human activity. That’s down from 77% and 47%, respectively, in January 2007. Read more »
