The storm formerly known as tropical cyclone 15S, now called Tropical Cyclone Ernie continued to strengthen as NASA's Aqua satellite captured a visible image that showed the storm developed an eye.

Record New Renewable Power Capacity Added at Lower Cost

April 7, 2017 - 12:50pm
As the cost of clean technology continues to fall, the world added record levels of renewable energy capacity in 2016, at an investment level 23 per cent lower than the previous year, according to new research published today by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance.Global Trends in Renewable Energy Investment 2017 finds that wind, solar, biomass and waste-to-energy, geothermal, small hydro and marine sources added 138.5 gigawatts to global power capacity in 2016, up 8 per cent from the 127.5 gigawatts added the year before. The added generating capacity roughly equals that of the world's 16 largest existing power producing facilities combined.

Tropical lowland frogs at greater risk from climate warming than high-elevation species, study shows

April 7, 2017 - 10:55am
A new study of Peruvian frogs living at a wide variety of elevations—from the Amazon floodplain to high Andes peaks—lends support to the idea that lowland amphibians are at higher risk from future climate warming.

An afternoon rainstorm might seem like an inconvenience at times, but rainfall is an essential part of the world ecosystem. Most of us know this.

Satellites map carbon sequestered by forests, with accuracy of up to ten metres

April 7, 2017 - 10:40am
Led by VTT, the EU North State project has developed a new method of using satellite images to evaluate the forest carbon balance. The carbon balance indicates how much carbon is sequestered or released by forests each year. This enables the carbon balance to be displayed on digital maps, with an accuracy of up to ten metres.

Scientists uncover isotopic fingerprint of N2O emissions from Arctic tundra

April 7, 2017 - 10:33am
A new study from the University of Eastern Finland presents, for the first time, the isotopic fingerprint of nitrous oxide produced by Arctic soils. The finding opens new avenues for predicting future trends in atmospheric nitrous oxide as well as in identifying climate change mitigation actions in the Arctic, a region that is particularly sensitive to climate change.

When peaceful coexistence turns into concurrence

April 6, 2017 - 10:02am
To find out how rising temperatures could affect species diversity, biologists from the German Centre for Integrative Biodiversity Research (iDiv) and the Leipzig University have developed a simple experiment: they covered the bottom of different Petri dishes with litter material, then put in two species of springtails, that is, arthropods only a few millimetres in size, and then added mites feeding on springtails. Subsequently, for some of the Petri dishes they increased the ambient temperature from originally 13.5°C to 18.5°C and for some other Petri dishes to 23.5°C. In those Petri dishes, the temperatures were hence five, respectively ten degrees higher than the conditions to which the animals had been exposed to in long-term cultures over years. This created simplified miniature ecosystems under climate change conditions, in which the springtail species that peacefully coexist in the wild represented the prey, and the mites represented the predators. For two months, the researchers then observed how the interactions between the three species would develop with different temperatures.

Where the Jordan Stops Flowing

April 3, 2017 - 12:24pm
A new study conducted at Tel Aviv University and published in the journal Water Research argues that Israel's Jordan River may be a useful case study for the challenges facing stream restoration initiatives around the world. The Jordan River has been ravaged by unbridled population growth and defunct sewage treatment plants.

NASA Sees the Remnants of Tropical Cyclone Debbie Moving off Australia's East Coast

March 31, 2017 - 5:40pm
The remnant clouds and showers associated with Ex-Tropical Cyclone Debbie were slowly moving off the coasts of Queensland and New South Wales as NASA's Terra satellite passed overhead on March 31.On March 31 at 01:30 p.m. AEST/Queensland (March 30 at 11:30 p.m. / U.S.), the Moderate Resolution Imaging Spectroradiometer aboard NASA's Terra satellite captured a visible image of Debbie's remnants. The remnant clouds and showers were blanketing southeastern Queensland and northeastern New South Wales, Australia. The system appeared frontal in nature, stretching from north to south over the eastern Australian coast.

Some of Greenland's coastal ice will be permanently lost by 2100

March 31, 2017 - 5:12pm
The glaciers and ice caps that dot the edges of the Greenland coast are not likely to recover from the melting they are experiencing now, a study has found.Researchers report in the current issue of the journal Nature Communications that melting on the island passed a tipping point 20 years ago. The smallest glaciers and ice caps on the coast are no longer able to regrow lost ice.

Energy Storage Solutions will help tackle Climate Change

March 31, 2017 - 10:51am
The UK is placing energy storage at the heart of its new Modern Industrial Strategy, due to its potential to support smart energy systems and the automotive sector. As the energy industry moves away from carbon-heavy production, the twin-approach of renewable energy and storage will be critical for delivering on the demand while securing the future of UK energy.

Why You Should Put Your Supercomputer in Wyoming

March 31, 2017 - 10:41am
Travel just few miles west of bustling Cheyenne, Wyoming, a you’ll find yourself in big-sky country. Tall-grass plains line the highway, snow-packed peaks pierce the sky, and round-edged granite formations jut out of the ground. But in this bucolic scene sits an alien building: a blocky, almost pre-fab structure with a white rotunda, speckled with dozens of windows that look out onto the grounds. Inside, it’s home to two supercomputers that focus on the vast landscape above.

Climate seesaw at the end of the last glacial phase – A warmer Europe cools down East Asia

March 31, 2017 - 10:34am
The climate of the Earth follows a complex interplay of cause-and-effect chains. A change in precipitation at one location may be caused by changes on the other side of the planet. A better understanding of these “teleconnections” – the linkages between remote places – may help to better understand local impacts of future climate change. A look into the climate of the past helps to investigate the teleconnections. An international team of Japanese, British, Australian, and German scientists, with the participation of the GFZ German Research Centre for Geosciences, now investigated Japanese lake sediments to decipher the interplay between local climate changes on the northern hemisphere about 12.000 years ago. Their results, now published as Nature Scientific Report, show that a regional warming in Europe caused a cooling and an increase in snowfall in East Asia.

Melting sea ice may lead to more life in the sea

March 30, 2017 - 6:26pm
When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, there are more and larger melt ponds.

Even short-duration heat waves could lead to failure of coffee crops

March 30, 2017 - 5:56pm
"Hot coffee" is not a good thing for java enthusiasts when it refers to plants beset by the high-temperature stress that this century is likely to bring, research at Oregon State University suggests.A study by OSU’s College of Forestry showed that when Coffea arabica plants were subjected to short-duration heat waves, they became unable to produce flowers and fruit.

NASA Examines the Rainfall Left Behind from Ex-Tropical Cyclone Debbie

March 30, 2017 - 5:46pm
Tropical Cyclone Debbie generated a lot of rainfall before and after it made landfall in Queensland, Australia, and NASA analyzed how much rain fell from a vantage point of space. NASA's Terra satellite provided a look at the remnants early on March 30 is it lingered near Australia's Gold Coast.

Emissions from the edge of the forest

March 30, 2017 - 5:08pm
When talk is of important ecosystems, tropical forests are top of the list. After all, half of the carbon stored in all of the Earth's vegetation is contained in these ecosystems. Deforestation has a correspondingly fatal effect. Scientists estimate that this releases 1000 million tonnes of carbon every year, which, in the form of greenhouse gasses, drives up global temperatures. That is not all, however, reveals a new study by the Helmholtz Centre for Environmental Research (UFZ) and the University of Maryland. A team of scientists has discovered that fragmentation of formerly contiguous areas of forest leads to carbon emissions rising by another third. Researchers emphasise in the scientific journal Nature Communications that this previously neglected effect should be taken into account in future IPCC (Intergovernmental Panel on Climate Change) reports.

A superbloom of wildflowers overtakes California's southeastern deserts in March 2017

March 30, 2017 - 9:22am
After five years of exceptional drought, desert landscapes across southern California exploded with “superblooms” of wildflowers this March following ample winter precipitation. According to local news reports, it’s the most spectacular display some locations have seen in more than two decades.

Tackling resilience: Finding order in chaos to help buffer against climate change

March 29, 2017 - 5:16pm
"Resilience" is a buzzword often used in scientific literature to describe how animals, plants and landscapes can persist under climate change. It’s typically considered a good quality, suggesting that those with resilience can withstand or adapt as the climate continues to change.But when it comes to actually figuring out what makes a species or an entire ecosystem resilient ― and how to promote that through restoration or management ― there is a lack of consensus in the scientific community.
