Rafts of garbage, assembled by currents that swirl trash together, clog our oceans. But how did that material wind up adrift in the first place? A new study takes a look at the refuse that washes up on a remote island in the South Atlantic and arrives at a perhaps-unexpected answer: The trash is being dumped from ships. The findings, published Monday in the Proceedings of the…

Hot and dry. These are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, the hot and dry conditions in the atmosphere determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn. Since 1880,…

Explosive outbreaks of dengue fever have rapidly spread in countries across Asia, killing more than 1,000 people, infecting hundreds of thousands and straining hospitals packed with sick families. Images from Bangladesh show patients in teeming hospital wards, lying beneath mosquito nets under lurid electric strip lights. Mothers cool their children from the sticky summer heat with hand-held fans while others rest on hospital floors, holding drips, waiting…

Protecting the traditional knowledge and territories of indigenous peoples means helping achieve a sustainable, hunger-free world and contributing to the fight against deforestation and climate change. For years, the importance of indigenous peoples in the fight against deforestation, land degradation, and climate change was overlooked and even denied, to the detriment of the environment and the food systems on which we all depend. Thanks to the global advocacy of indigenous peoples and…

As scientists learn more about the importance of animals to nature’s carbon-sequestering capabilities, they’ve come to understand that extinctions and extirpations are climate issues. Two new studies add powerful detail to that insight. The first, led by ecologist Fabio Berzaghi of Italy’s University of Tuscia and published in Nature Geoscience, drew on 17 years of data on vegetation structure and species competition in northern Congo. With elephants…

Floating plastic garbage has swamped a remote Pacific island once regarded as an environmental jewel and scientists say little can be done to save it while a throwaway culture persists. Henderson Island is an uninhabited coral atoll that lies almost exactly halfway between New Zealand and Peru, with 5,500 kilometers (3,400 miles) of the ocean in either direction. Despite its extreme isolation, a freak confluence…

If Earth's resources were a bank account, today would mark the date we'd officially be in the red. As of July 29, humanity has officially used up more ecological resources this year than the Earth can regenerate by the end of the year. The occasion even has a name: Earth Overshoot Day. The Global Footprint Network, a sustainability organization which calculates the day, says humanity…

A new study from the World Bank and UN finds we’ll need ways to boost yields faster than ever before to prevent agricultural emissions from soaring. With the global population projected to increase by nearly 3 billion people by midcentury, demand for food—as well as the land and energy required to produce it—is to set to soar. If the world doesn’t figure out ways to…

As global temperatures reach record highs, providing cooling systems which are effective, sustainable and which do not harm the environment is increasingly essential for everyday life. That’s according to Rachel Kyte, Chief Executive Officer of Sustainable Energy for All, and Special Representative of the United Nations Secretary-General for Sustainable Energy for All (SEforALL). From the cold chain systems that maintain uninterrupted refrigeration during the delivery…

A new study released July 1 in Nature Climate Change gives hope for coral reefs. Launched by the nonprofit Coral Reef Alliance, with lead and senior authors at the University of Washington, the study is one of the first to demonstrate that management that takes evolution and adaptation into account can help rescue coral reefs from the effects of climate change. Importantly, the results show that by making…

WASHINGTON: Greenland’s ice sheet may have completely melted within the next millennium if greenhouse gas emissions continue at their current rate, according to a new study with implications for sea-level rise around the world. The Greenland ice sheet holds the equivalent of seven meters (yards) of sea level. “If we continue as usual, Greenland will melt,” said lead author Andy Aschwanden, a research associate professor…

Their favorite meal, herring, abounds, but climate change means both predator and prey must increasingly migrate further north. The clear and calm waters of Reisafjorden, in Norway’s Far North, have in recent years become the winter playground of the Scandinavian country’s killer whale population. At three degrees Celsius (37 Fahrenheit), the cold water is perfect for the herring which, ahead of the spawning…

Scientists at the US-based advocacy group the Environmental Defense Fund suggest the short-term warming impact of these additional gases in the atmosphere could be equivalent to 1,200 coal power plants. Considering the importance of rice as a staple food crop, providing more calories to the global population than any other food, the researchers have recommended ways to adapt farming practices and make its cultivation…

So far, advocates and politicians have tended to focus on reducing fossil fuel consumption through technology and/or policy, such as a steep carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions—71 percent of which are generated by just 100 fossil fuel companies. For this reason, fossil-fuel–related emissions reductions rightly figure heavily in the national climate commitments of the…

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 rates of return on investment range from 17 percent…

The Annual Meetings took place in the wake of a new report published by the Intergovernmental Panel on Climate Change in early October, which warned that governments have just 12 years to reduce global greenhouse (GHG) emissions by 45per cent to avert irreversible global warming and limit global average temperature rise to 1.5°C. Countries’ current Nationally Determined Contributions to the Paris Climate Agreement (NDCs) put…

Global heating and ocean acidification have already severely bleached 16 to 33% of all warm-water reefs, but the remainder is vulnerable to even a fraction of a degree more warming, said David Obura, chair of the Coral Specialist Group in the International Union for the Conservation of Nature. “It will be like lots of lights blinking off,” he told the Observer. “It won’t happen…

Since 2010, new plant varieties have been developed in molecular laboratories using new plant breeding techniques (NPBTs), including tilling, protoplast fusion, cisgenesis, oligonucleotide techniques, CRISPR-Cas9 and Talen, with CRISPR-Cas9 being more prominent than the rest. With these methods, there is no transfer of a gene from a foreign species like there is with GMOs. On the contrary, new varieties are created by silencing the target…

In Bangladesh, low-lying and vulnerable to yearly flooding, farmers are shifting from raising chickens to raising ducks. Ducks can swim. In the Philippines, where half the mangrove forests have been lost to development, biologists are replanting the trees to recreate nature’s protective coastal shield against deadly typhoons. The gnarled tangle of mangrove roots slows the movement of tidal…
