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

Climate Change News - ENN - 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

Climate Change News - ENN - 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.

How Changes in Rainfall Impact the World Economy

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

Climate Change News - ENN - 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

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

Climate Change News - ENN - 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.

Lightform: The Magical Little Device That Transforms Whole Rooms Into Screens

Technology wants to disappear. In computing’s early days, the machines swallowed entire rooms. Today, we wear them on our wrists. Soon, they could vanish completely, their smarts embedding directly into our surroundings.

Buckle up! Climate Change to Increase Severe Aircraft Turbulence

Turbulence strong enough to catapult unbuckled passengers and crew around the aircraft cabin could become twice or even three times as common because of climate change, according to a new study from the University of Reading published in Advances in Atmospheric Sciences (AAS), an international journal published by Springer and hosted by the Institute of Atmospheric Physics, Chinese Academy of Sciences.

University Research Teams to Study Potential Aeronautical Innovations

Imagine an aircraft structure that can change its shape in flight to reduce the sonic boom noise produced by supersonics airplanes. Or imagine an airliner that can take-off and fly with a quiet and energy efficient electric propulsion system.

Tiny Whiteflies Provide Insight into Stabilizing Manmade Drones During Takeoff

When whiteflies take off, they don't just spread their wings and fly. Just .03 of an inch long, these tiny insects possess a variety of sophisticated techniques that provide them with exceptional stability in the air. Tel Aviv University researchers now say that they may hold the secret to stabilizing the take-off of small robotic manmade flyers such as miniaturized drones.

Potentially Explosive Methane Gas Mobile in Groundwater, Poses Safety Risk: Study

Potentially explosive methane gas leaking from energy wells may travel extensively through groundwater and pose a safety risk, according to a new study by University of Guelph researchers.

You Could Soon Print Out Simple Electronics With Your Deskjet

Computers used to require entire buildings to operate. Now they fit in our pockets. Similarly, factory-size electronics manufacturing is approaching a contraction. Want proof? Look at that $50 printer on your desk and imagine, instead of using it to spit out a hard copy of that thank-you note, that you used it to print some digital memory.

Where the Jordan Stops Flowing

Climate Change News - ENN - 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.

Exploring ocean waters to characterize atmospheric aerosols

Aerosols are collections of fine particles, either biological or of other types, in suspension in a gaseous medium. They play a major role in cloud formation and therefore have a strong impact on climate models. They are however extremely hard to study due to the small size and immense variety of their constituent particles. But researchers from the University of Geneva (UNIGE), Switzerland, members of the PlanetSolar Deepwater expedition, have now succeeded in linking the composition of marine biological aerosols - and therefore their influence on the climate - to that of bodies of water under them within the Atlantic Ocean, thereby paving the way to an indirect study of these aerosols through water analysis. This study, which has been published in Scientific Reports, will contribute to making climate models more accurate.

Battling nature's nasty side

When told the subject of her research has a bit of an alien predator vibe, Natacha Hogan is quick to agree.“Oh, I like that,” said the assistant professor in the Department of Animal and Poultry Science. “When you look at the structures of these mycotoxins, some really are scary looking. Many are very complex structures with multiple rings fused together and many functional groups hanging off the sides. They sort of look like spiders.”

London researchers enroll first Canadian patients in trial of tissue implant using patients' own cartilage cells

Dr. Alan Getgood and his team at Western University and Lawson Health Research Institute are the first in Canada to participate in an investigative trial to determine the safety and efficacy of using a patient’s own cartilage cells to repair knee cartilage injuries.

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

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.
