Self-powered movable seawall for tsunami protection and emergency power generation      (via sciencedaily.com)     Original source 

A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in natural disasters. This innovative system integrates disaster prevention with the use of renewable energy.

Global warming has a bigger effect on compact, fast-moving typhoons      (via sciencedaily.com)     Original source 

A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.

Ancient brown bear genomes sheds light on Ice Age losses and survival      (via sciencedaily.com)     Original source 

The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?

New tool predicts flood risk from hurricanes in a warming climate      (via sciencedaily.com)     Original source 

A new method predicts how much flooding a coastal community is likely to experience as hurricanes evolve due to climate change. Using New York as a test case, the model predicts Hurricane Sandy-level flooding will occur roughly every 30 years by 2099.

Ice age could help predict oceans' response to global warming      (via sciencedaily.com)     Original source 

A new way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age could help explain the role oceans played in past glacial melting cycles and improve predictions of how ocean carbon cycles will respond to global warming.

Wobbling particles in the sky      (via sciencedaily.com)     Original source 

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.

Climate change linked to spread of diarrheal illness      (via sciencedaily.com)     Original source 

Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.

Butterflies could lose spots as climate warms      (via sciencedaily.com)     Original source 

Female meadow brown butterflies have fewer spots if they develop in warmer weather -- so climate change could make them less spotty, new research shows.

The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance      (via sciencedaily.com)     Original source 

Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.

Climate change isn't producing expected increase in atmospheric moisture over dry regions      (via sciencedaily.com)     Original source 

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected.

Stalagmites as climate archive      (via sciencedaily.com)     Original source 

When combined with data from tree-ring records, stalagmites can open up a unique archive to study natural climate fluctuations, a research team has demonstrated. The researchers analyzed the isotopic composition of oxygen in a stalagmite formed from calcareous water in a cave in southern Germany. In conjunction with the data acquired from tree rings, they were able to reconstruct short-term climate fluctuations over centuries and correlate them with historically documented environmental events.

Key moment in the evolution of life on Earth captured in fossils      (via sciencedaily.com)     Original source 

New research has precisely dated some of the oldest fossils of complex multicellular life in the world, helping to track a pivotal moment in the history of Earth when the seas began teeming with new lifeforms -- after four billion years of containing only single-celled microbes.

Thermal vision shows endangered numbats feel the heat of warming climate      (via sciencedaily.com)     Original source 

Research using thermal imaging of numbats in Western Australia has found that during hot weather the endangered animals are limited to as little as ten minutes of activity in the sun before they overheat to a body temperature of greater than 40 C.

The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years      (via sciencedaily.com)     Original source 

Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time capsule, allowing scientists and historians to link Earth's history with that of human societies. In a new study, ice cores from Antartica show that lead and other toxic heavy metals linked to mining activities polluted the Southern Hemisphere as early as the 13th century.
