The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.
Climate change could decrease the yield of some crops in California by up to 40 percent by 2050. That’s a big deal for farmers in the state, which provides about two-thirds of the nation’s produce.
California farmers grow more than 400 commodity crops. Tapan Pathak, a University of California Cooperative Extension specialist based in California’s Central Valley, and his research team analyzed 89 studies on climate change and discovered that warming temperatures may alter where crops grow across the state. Their findings were published in the journal Agronomy.
“In order to make California agriculture more sustainable, we have to act now,” Pathak says.
The Arctic spring is arriving 16 days earlier than it did a decade ago, according to a new study which shows climate change is shifting the season earlier more dramatically the further north you go.
The research, published on Friday in the journal Scientific Reports, comes amid growing concern about the warming of Greenland, Siberia, Alaska and other far northern regions, which have recently experienced unusually prolonged and frequent midwinter temperature spikes.
As the price of renewable energy drops, more cities are cutting the cord with fossil fuel-based electricity.
A new report released Tuesday by the environmental group CDP finds that more than 100 cities worldwide now get the majority of their power—70 percent or more—from renewables. That’s up from 42 in 2015, when countries pledged to cut greenhouse gas emissions in the Paris climate agreement.
CDP notes that more than 40 of those cities are now powered entirely by renewables, including Burlington, Vermont, which gets its electricity from a combination of wind, solar, hydro and biomass. Burlington will have more company within the next 20 years—58 U.S. cities, including Atlanta and San Diego, having announced plans to do the same.
While the Eastern United States simmered in some of its warmest February weather ever recorded Tuesday and Wednesday, the Arctic is also stewing in temperatures more than 45 degrees above normal. This latest huge temperature spike in the Arctic is another striking indicator of its rapidly transforming climate.
On Monday and Tuesday, the northernmost weather station in the world, Cape Morris Jesup at the northern tip of Greenland, experienced more than 24 hours of temperatures above freezing according to the Danish Meteorological Institute.
“How weird is that?” tweeted Robert Rohde, a physicist and lead scientist at Berkeley Earth, a non-profit organization that conducts analyses of the Earth’s temperature. “Well it’s Arctic winter. The sun set in October and won’t be seen again until March. Perpetual night, but still above freezing.”
On a sunny day this past October, three dozen people file into a modest, mint-green classroom at Montana State University (MSU) in Bozeman to glimpse a vision of the future. Some are scientists, but most are people with some connection to the land: extension agents who work with farmers, and environmentalists representing organizations such as The Nature Conservancy. They all know that climate change will reshape the region in the coming decades, but that’s not what they’ve come to discuss. They are here to talk about the equally profound impacts of trying to stop it.
Paul Stoy, an ecologist at MSU, paces in front of whiteboards in a powder blue shirt and jeans as he describes how a landscape already dominated by agriculture could be transformed yet again by a different green revolution: vast plantations of crops, sown to sop up carbon dioxide (CO2) from the sky. “We have this new energy economy that’s necessary to avoid dangerous climate change, but how is that going to look on the ground?” he asks.
At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
