Rainfall changes for key crops predicted

Even if humans radically reduce greenhouse gas emissions soon, important crop-growing regions of the world can expect changes to rainfall patterns by 2040. In fact, some regions are already experiencing new climatic regimes compared with just a generation ago. The study, published March 11 in Proceedings of the National Academy of Sciences, warns that up

Research connects dots among ocean dynamics, drought and forests

In a time of drastic change, humans look for predictability. A recent study led by a University of Wyoming researcher found that even in dramatically changing climates, mechanisms can be found that predict how those changes will play out. The last ice age was 11,000 years ago and, since then, climates have continuously changed, triggering

Climate change is shifting productivity of fisheries worldwide

Fish provide a vital source of protein for over half the world's population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food. A team of scientists led by Christopher Free, a postdoctoral scholar at UC

Natural and industrial approaches to global decarbonization

In the fight to slow climate change, nature is a powerful weapon. In fact, natural climate solutions, such as reducing deforestation and changing farming practices, can soak up excess carbon in the atmosphere and prevent certain emissions so effectively that it might be tempting to think they can buy us time while we figure out

Climate change makes summer weather stormier yet more stagnant

Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new MIT study finds. Scientists report that rising global temperatures, particularly in the Arctic, are redistributing the energy

How small farmers could be leading the way towards sustainable agriculture

Agriculture is a leading cause of climate change, but it is also undeniably affected by it. Farming must therefore change in order to keep up with global demands, while reducing its environmental impact. Without these necessary changes, it’s estimated that by 2030, the impacts of climate change will be even worse, causing yields to decline

Asia faces contradictions with climate change

On Saturday climate change delegates concluded their latest round of negotiations on implementing the Paris agreement at the UN climate conference in Katowice, Poland. The delegates at COP24 worked to agree on a so-called "rule book" for the Paris agreement that spells out a cohesive set of standards and procedures for enacting emissions-reducing policies to be followed

National Climate Assessment Signals Big Impacts for Southeast

“Earth’s climate is now changing faster than at any point in the history of modern civilization, primarily as a result of human activities. The impacts of global climate change are already being felt in the United States and are projected to intensify in the future—but the severity of future impacts will depend largely on actions

Climate change in the US will hurt poor people the most..

Climate change will hit low-income communities the hardest as it takes a toll on the U.S. in general, says a blockbuster government report released on Friday. Low-income communities in both urban and rural areas will be disproportionately impacted by climate change relative to other communities, according to the assessment, which was created by a team

Farmers know climate change is real —

Craig Dunnum didn’t read the recently released National Climate Assessment (NCA), which predicts the nation’s farm commodity contribution to the economy — $136.7 billion in 2016, already low due to falling prices — will be increasingly vulnerable to droughts, floods, pests and disease. Instead, he lived it. The fourth-generation farmer in south-central Wisconsin has been

Humans may be reversing the climate clock, by 50 million years

In a study published Monday (Dec. 10, 2018) in the Proceedings of the National Academy of Sciences, researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it's taken just two centuries. By 2030, Earth's climate is expected to resemble that of the mid-Pliocene, going back more

Greenland ice sheet melt ‘off the charts’..

Surface melting across Greenland's mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research published Dec. 5, 2018, in the journal Nature. The study provides new evidence of the impacts of climate change on Arctic

World Bank promises $200 bn in 2021-25 climate cash

The World Bank on Monday unveiled $200 billion in climate action investment for 2021-25, adding this amounts to a doubling of its current five-year funding. The World Bank said the move, coinciding with a UN climate summit meeting of some 200 nations in Poland, represented a "significantly ramped up ambition" to tackle climate change, "sending

Extreme heat increasing in both summer and winter

A new study in the in Journal of Geophysical Research: Atmospheres, a publication of the American Geophysical Union, examined absolute extreme temperatures -- high temperatures in summer and low temperatures in winter -- but also looked at relative extreme temperature events -- unusually cold temperatures and unusually warm temperatures throughout the year. The new study

Climate Change Drives Up Rural Poverty in Latin America

Only 18 percent of the population of Latin America and the Caribbean live in rural areas, but these are increasingly hotbeds of poverty, and climate change is playing a major role in this phenomenon. Stories of extreme drought followed by flash floods that virtually destroy entire crops and wreak chaos abounded during the region’s first

How to Demand Action on Climate Change

Last week, the Intergovernmental Panel on Climate Change released a report—a klaxon, really—warning of the catastrophic consequences of climate change if global political leaders don’t take action right now. For people who’ve been sounding the alarm for decades now, this report is depressing but not surprising; for those of us who’ve not paid as much attention to

Climate change and the 75% problem

Quick: Think of some inventions that help fight climate change. What came to mind first? I bet you thought of solar panels and wind turbines. In my experience, that’s what people point to when they think about reducing greenhouse gas emissions. They’re not wrong. Renewables are getting cheaper and many countries are committing to rely

Role of “natural factors” on recent climate change underestimated, research shows

Pioneering new research has given a new perspective on the crucial role that ‘natural factors’ play in global warming. The study, by Dr Indrani Roy at the University of Exeter, suggests that the natural phenomena such as solar eleven-year cycles and strong volcanic explosions play important roles in recent climate change which has been ‘underestimated’.
