For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable data on how polar ice is changing in a warming world. Now, for the first time, the campaign will expand its reach to explore the Arctic’s Eurasian Basin through two research flights based out of Svalbard, a Norwegian archipelago in the northern Atlantic Ocean.

Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.

It is rare in biology that a single trait can answer questions spanning several fields of research. One such trait is plant biology’s “leaf mass per area,” a simple measurement calculated by weighing a dried leaf and dividing by its original fresh area. Leaf mass per area, or LMA, which has been measured in thousands of studies, is used in nearly every field of plant biology to make predictions of many processes and properties such as leaf photosynthetic rates, nitrogen content and plant environmental preferences.

Climate projections for West Africa show that crop yields and grass for livestock grazing are likely to decline in the future. But a new study in the journal Global Environmental Change shows that when ineffective institutions and political instability limit investment in agriculture climate change would have greater impacts on regional food security.

West Africa is a major producer of crops such as cassava, millet, and sorghum but in the future, regional production may not be able to meet the growing demand for food and livestock feed. “How and to what extent the region’s agricultural sector develops in the future will have profound implications for the livelihoods of millions of people,” says IIASA researcher Amanda Palazzo, who led the study.

Iran can transition to a fully renewable electricity system and financially benefit from it by 2030. Researchers at Lappeenranta University of Technology (LUT) show that major oil-producing countries in the Middle East and North Africa (MENA) region could turn their abundant renewable energy resources into lucrative business opportunities in less than two decades.

Plants are blooming early across the country as a result of this winter’s ongoing record warmth, which many connect to climate change. And some fear that an impending freeze could destroy countless fruit flowers and wreak havoc on the industry.

Chicago—a city well known for its windy and snowy winters—is experiencing some unusually warm weather. For the first time in 146 years, there was no documented snow on the ground in January and February, according to the local National Weather Service.

Scientists have long suspected that ice caps formed repeatedly in the tropical Andes during the late Pliocene, but only evidence of a single glaciation was known until now.

Despite recent changes to the growing season for plants in the Arctic, Alaska, caribou appear to have remained in sync with these changes over the last 30 years. 

You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care.

As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.
