The winds of climate change and migratory birds

Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers from the Cornell Lab of Ornithology came to this conclusion using data from 143 weather radar stations to estimate the altitude,…

Climate-proof farms have big upside

The study examines 10 major climate-related issues facing farmers in Africa, Asia and Latin America and proposes site-specific CSA remedies. These include rotating rice fields with peanuts in Vietnam, manual blight control for cacao in Nicaragua, and planting drought-tolerant varieties of beans and maize alongside each other in Uganda. Where additional investment is required, initial…

Greenland Is Melting Frighteningly Fast

In July 2012, a spate of warm weather caused nearly the entire surface of the Greenland ice sheet to begin melting, an event with no precedent in the satellite record. A new study shows this massive melt-out wasn’t just an anomaly compared with the last 40 years, but the last 350. Unfortunately, the study also…

Carbon emissions rising in wealthy nations

Carbon dioxide emissions from advanced economies will rise in 2018 for the first time in five years, the International Energy Agency reports, marking a setback for the global campaign to fend off the worst effects of climate change. Energy-related carbon emissions from North America, Europe and developed nations in the Asia-Pacific region are set to…

Citizen input to improve flood modelling

With increasing floods and flash floods in recent decades, researchers are working to develop improved methods for flood prevention and warning. A new Journal of Flood Risk Management study points to the potential of an approach that integrates water level data reported by citizens into flood forecasting models. The study found that although simple, the…

$200 Billion from World Bank to Fight Climate Change

“Climate change is an existential threat to the world’s poorest and most vulnerable. These new targets demonstrate how seriously we are taking this issue, investing and mobilizing $200 billion over five years to combat climate change,” World Bank Group President Jim Yong Kim said in a statement. “We are pushing ourselves to do more and…

8 steps to increase soil carbon 

In a commentary piece, Put More Carbon in Soils to Meet Paris Climate Pledges, published today by the journal Nature, climate change and agricultural scientists who serve on the science and technical committee of the organization 4 per 1000 describe a path for recuperating soil carbon stocks to mitigate climate change and boost soil fertility….

Risk of ‘extinction domino effect’

New research reveals the extinction of plant or animal species from extreme environmental change increases the risk of an ‘extinction domino effect’ that could annihilate all life on Earth. This would be the worst-case scenario of what scientists call ‘co-extinctions’, where an organism dies out because it depends on another doomed species, with the findings…

The Climate Apocalypse Is Happening to You

Fewer than half of Americans think climate change is a right-here, right-now problem. So it’s critical that a new report on the impact of climate change is about the present as much as the future. The topline results: 157 million more people experienced a heat wave in 2016 than in 2000—12.3 million Americans. That heat…

Triple efforts or face catastrophic climate change

Countries are failing to take the action needed to stave off the worst effects of climate change, a UN report has found, and the commitments made in the 2015 Paris agreement will not be met unless governments introduce additional measures as a matter of urgency. New taxes on fossil fuels, investment in clean technology and…
