"Ongoing climate change can alter conditions for plant growth, in turn affecting ecological and social systems. While there have been considerable advances in understanding the physical aspects of climate change, comprehensive analyses integrating climate, biological, and social sciences are less common. Here we use climate projections under alternative mitigation scenarios to show how changes in environmental variables that limit plant growth could impact ecosystems and people. We show that although the global mean number of days above freezing will increase by up to 7% by 2100 under “business as usual” (representative concentration pathway [RCP] 8.5), suitable growing days will actually decrease globally by up to 11% when other climatic variables that limit plant growth are considered (i.e., temperature, water availability, and solar radiation). Areas in Russia, China, and Canada are projected to gain suitable plant growing days, but the rest of the world will experience losses. Notably, tropical areas could lose up to 200 suitable plant growing days per year. These changes will impact most of the world’s terrestrial ecosystems, potentially triggering climate feedbacks. Human populations will also be affected, with up to ~2,100 million of the poorest people in the world (~30% of the world’s population) highly vulnerable to changes in the supply of plant-related goods and services. These impacts will be spatially variable, indicating regions where adaptations will be necessary. Changes in suitable plant growing days are projected to be less severe under strong and moderate mitigation scenarios (i.e., RCP 2.6 and RCP 4.5), underscoring the importance of reducing emissions to avoid such disproportionate impacts on ecosystems and people."

"Going “over the river and through the woods to Grandmother’s house” this holiday season could require a significant amount of gasoline if you’re traveling by car. Before you hit the road to visit relatives or friends, you’ll probably stop at the gas station to fuel up. The Energy Department’s Bioenergy Technologies Office invests in research and development to help commercialize biofuels—liquid fuels produced from plant sources—to reduce America’s dependence on foreign oil, build the economy, and reduce greenhouse gas emissions."
"Alaska Airlines is to purchase renewable jet fuel from Gevo and fly the first-ever commercial alcohol-to-jet fuel (ATJ) flight, after the two companies signed a strategic alliance agreement."
"The SUN Day Campaign’s Ken Bossong, has noted once again that renewable energy sources are dominating the new energy landscape according to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects. The reports shows wind and solar accounted for all new generating capacity placed in-service in April. For the month, two “units” of wind (the 300 MW Hereford-2 Wind Farm Project in Deaf Smith County, TX and the 211 MW Mesquite Creek Wind Project in Dawson County, TX) came on line in addition to six new units – totaling 50 MW – of solar."
"The world's seas are rising faster than previously thought, offering stark evidence that global warming is posing dire challenges to coastal communities around the world."
"US ethanol production averaged 927,000 b/d in April, according to the Energy Information Administration, with full-year 2015 production expected to average 936,000 b/d, or 14.35 billion total gallons.
US biodiesel output will average 81,000 b/d in 2015, or 1.24 billion total gallons, the EIA said in its May Short-Term Energy Outlook."
"Forests could save the planet, we all know that. But a new United Nations-backed report on the link between forests and food production and nutrition says that woodlands could be the key to ending hunger and will be intimately linked to the global fight against climate change."
"Carbon negative options have been studied for years. However, today biomass plantations and biochar can easily be a part of any project aiming to mitigate climate change.
In California, a new UC Berkeley study shows that if biomass electricity production is combined with carbon capture and sequestration in the western United States, by 2050 power generators could reduce emissions up to 145 percent from 1990 levels, even while retaining gas- or coal-burning plants. Such reductions can occur with as little as 7 percent of the power coming from “Bioenergy combined with Carbon Capture & Sequestration”, also known as BECCS."
"In California, if advanced biofuels are to replace gasoline, diesel and jet fuel on a gallon-for-gallon basis at competitive pricing, we’re going to need a new generation of fuel crops – plants designed specifically to serve as feedstocks for fuels."
