Changes in rainfall have already impacted water quality

Changes in temperature and precipitation have already impacted the amount of nitrogen introduced into U.S. waterways, according to new research from a team of three Carnegie ecologists published this week in Environmental Science & Technology. Nitrogen from agriculture and other human activities washes into waterways, which, in excess, creates a dangerous phenomenon called eutrophication. This

The shockingly simple way to make packaging more sustainable

If you quickly scan through the products under your sink–counter spray, window cleaner, dish soap–they all have one thing in common: Water is their main ingredient. Until now, few consumers thought this was a problem. But as a growing number of people become increasingly aware of both climate change and plastic pollution, the outsize environmental impact

Climate change to blame for Hurricane Maria’s extreme rainfall

Hurricane Maria dropped more rain on Puerto Rico than any storm to hit the island since 1956, a feat due mostly to the effects of human-caused climate warming, new research finds. A new study analyzing Puerto Rico's hurricane history finds 2017's Maria had the highest average rainfall of the 129 storms to have struck the

New research reveals evidence of climate change in the Yukon

A study from U of T Mississauga uses new research techniques to reveal alarming information about climate change in Canada’s north. A study published in Nature Communications confirms that recent climate warming in the central Yukon region has surpassed the warmest temperatures experienced in the previous 13,600 years, a finding that could have important implications in the

Global warming disrupts recovery of coral reefs

The damage caused to the Great Barrier Reef by global warming has compromised the capacity of its corals to recover, according to new research published today in Nature. "Dead corals don't make babies," said lead author Professor Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU).

Humanitarian crises and climate change—

Burundi, Chad and Sudan are home to some of the world’s largest displaced populations and vulnerable communities. Burundi’s Gitega Province, which has one of the country’s highest population densities, hosts several thousands of people in refugee settlements and camps. About 96 per cent of families use fuelwood as a primary energy source for cooking. In

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

Sustainable Finance Is Growing in the World’s Worst-Polluting Country

Tao Zhang is bullish on sustainability in China—especially when it comes to livestock emissions. The founder of U.S.-China impact investing consortium Dao Ventures has spent much of the past year looking to accelerate investment in more environmentally friendly plant-based or lab-grown meat for Chinese consumers through a new company, Dao Foods. Climate change activists are

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

5 Sustainable Investing Trends From 2018

1. Growing Climate Risk The biggest sustainability challenge the world faces today is global warming, and two reports released this fall underscored its magnitude. The report of the Intergovernmental Panel on Climate Change, written by scientists convened by the United Nations and released in October, finds that the world is currently on a path to warm by

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
