On a windswept Icelandic plateau, an international team of engineers and executives is powering up an innovative machine designed to alter the very composition of Earth’s atmosphere. If all goes as planned, the enormous vacuum will soon be sucking up vast quantities of air, stripping out carbon dioxide and then locking away those greenhouse gases […]

Angry Farmers Are Reshaping Europe
Gazing out from his 265-acre farm to the silhouetted Jura mountains in the distance, Jean-Michel Sibelle expounded on the intricate secrets of soil, climate and breeding that have made his chickens — blue feet, white feathers, red combs in the colors of France — the royalty of poultry. The “poulet de Bresse” is no ordinary […]
Read MoreAtmospheric observations in China show rise in emissions of a potent greenhouse gas
To achieve the aspirational goal of the Paris Agreement on climate change — limiting the increase in global average surface temperature to 1.5 degrees Celsius above preindustrial levels — will require its 196 signatories to dramatically reduce their greenhouse gas (GHG) emissions. Those greenhouse gases differ widely in their global warming potential (GWP), or ability […]

Nike’s competitive advantage is not in its products but in its brand. Nike spends most of its time and energy putting together ad campaigns featuring the swoosh. A generic gray shirt might sell for $10, but the same shirt made in the same factory with a swoosh printed on it sells for three times more. […]
Read MoreMIT-derived algorithm helps forecast the frequency of extreme weather
To assess a community’s risk of extreme weather, policymakers rely first on global climate models that can be run decades, and even centuries, forward in time, but only at a coarse resolution. These models might be used to gauge, for instance, future climate conditions for the northeastern U.S., but not specifically for Boston. To estimate […]
Read MoreArtificial reef designed by MIT engineers could protect marine life, reduce storm damage
The beautiful, gnarled, nooked-and-crannied reefs that surround tropical islands serve as a marine refuge and natural buffer against stormy seas. But as the effects of climate change bleach and break down coral reefs around the world, and extreme weather events become more common, coastal communities are left increasingly vulnerable to frequent flooding and erosion. An […]
Read MoreUnderstanding the impacts of mining on local environments and communities
Hydrosocial displacement refers to the idea that resolving water conflict in one area can shift the conflict to a different area. The concept was coined by Scott Odell, a visiting researcher in MIT’s Environmental Solutions Initiative (ESI). As part of ESI’s Program on Mining and the Circular Economy, Odell researches the impacts of extractive industries […]
Read MoreLessons from Fukushima: Prepare for the unlikely
When a devastating earthquake and tsunami overwhelmed the protective systems at the Fukushima Dai’ichi nuclear power plant complex in Japan in March 2011, it triggered a sequence of events leading to one of the worst releases of radioactive materials in the world to date. Although nuclear energy is having a revival as a low-emissions energy […]
Read MoreStudy finds lands used for grazing can worsen or help climate change
When it comes to global climate change, livestock grazing can be either a blessing or a curse, according to a new study, which offers clues on how to tell the difference. If managed properly, the study shows, grazing can actually increase the amount of carbon from the air that gets stored in the ground and […]
Read MoreReducing pesticide use while increasing effectiveness
Farming can be a low-margin, high-risk business, subject to weather and climate patterns, insect population cycles, and other unpredictable factors. Farmers need to be savvy managers of the many resources they deal, and chemical fertilizers and pesticides are among their major recurring expenses. Despite the importance of these chemicals, a lack of technology that monitors […]
Read MoreA new sensor detects harmful “forever chemicals” in drinking water
MIT chemists have designed a sensor that detects tiny quantities of perfluoroalkyl and polyfluoroalkyl substances (PFAS) — chemicals found in food packaging, nonstick cookware, and many other consumer products. These compounds, also known as “forever chemicals” because they do not break down naturally, have been linked to a variety of harmful health effects, including cancer, […]
