Flooding risk: America's most vulnerable communities

Earth & Climate - 星期三, 06/21/2017 - 23:40
Floods are the natural disaster that kill the most people. They are also the most common natural disaster. As the threat of flooding increases worldwide, a group of scientists have gathered valuable information on flood hazard, exposure and vulnerability in counties throughout the US.

Climate change label leads to climate science acceptance

Earth & Climate - 星期三, 06/21/2017 - 22:32
Labels matter when it comes to acceptance of climate science, suggests new research. For example, explain authors of a new report, the US public doubts the existence of 'global warming' more than it doubts 'climate change.'

Accelerating rate of temperature rise in the Pyrenees

Earth & Climate - 星期三, 06/21/2017 - 22:31
The Iberian Peninsula is undergoing climate change, with temperatures on the rise, and mountain ranges are not exempt from this trend. A team of scientists has analyzed regional climate series from the Central Pyrenees for 1910 to 2013 (the most extensive climate records to date for the area), concluding that temperatures have risen at an increasing rate since 1970, particularly in spring and summer.

New catalyst paves way for carbon neutral fuel

Earth & Climate - 星期三, 06/21/2017 - 22:31
Scientists have paved the way for carbon neutral fuel with the development of a new efficient catalyst that converts carbon dioxide (CO2) from the air into synthetic natural gas in a 'clean' process using solar energy.

Hot summer frequents Europe-west Asia and northeast Asia after the mid-1990s

Earth & Climate - 星期三, 06/21/2017 - 22:30
A recent research identifies a nonuniform warming pattern in summer after the mid-1990s over the Eurasian continent, with a predominant amplified warming over Europe-West Asia and Northeast Asia but much weaker warming over Central Asia. The study also implies that there will still be a strong warming over Europe-West Asia and Northeast Asia in the coming decade.

How phytoplankton rule the oceans

Earth & Climate - 星期三, 06/21/2017 - 02:30
Photosynthesis is a unique biological process that has permitted the colonization of land and sea by plants and phytoplankton respectively. While the mechanisms of photosynthesis in plants are well understood, scientists are only now beginning to elucidate how the process developed in phytoplankton.

Corn better used as food than biofuel, study finds

Earth & Climate - 星期三, 06/21/2017 - 02:29
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

Making waves with the hot electrons within Earth's radiation belts

Earth & Climate - 星期三, 06/21/2017 - 00:11
An international team of scientists recently discovered the role that hot electrons may play in the waves and fluctuations detected by satellites. The results are based on data collected by the Van Allen Probes, twin robotic spacecraft launched by NASA in 2012 to help scientists better understand these belt regions.

Wave beams mix and stir the ocean to create climate

Earth & Climate - 星期二, 06/20/2017 - 23:42
Waves deep within the ocean play an important role in establishing ocean circulation, arising when tidal currents oscillate over an uneven ocean bottom. The internal waves generated by this process stir and mix the ocean, bringing cold, deep water to the surface to be warmed by the sun. Investigators now explain how to tell which way internal waves will go. The proposed theory unifies several previously understood explanations of wave propagation.

Solar heating could cover over 80 percent of domestic heating requirements in Nordic countries

Earth & Climate - 星期二, 06/20/2017 - 23:41
By using suitable systems, more than 80 percent of heating energy for Finnish households could be produced using solar energy with competitive prices. This result is also valid for Sweden, Norway, Alaska, northern Canada and other locations at the same latitudes.

Future trucks fueled by hydrogen created with solar power: Exhaust? Pure water vapor

Earth & Climate - 星期二, 06/20/2017 - 21:45
Heavy-duty trucks will soon be driving around in Trondheim, Norway, fueled by hydrogen created with solar power, and emitting only pure water vapor as “exhaust”. Not only will hydrogen technology revolutionize road transport, it will also enable ships and trains to run emission-free.

Wet and stormy weather lashed California coast... 8,200 years ago

Earth & Climate - 星期二, 06/20/2017 - 21:32
An analysis of stalagmite records from White Moon Cave in the Santa Cruz Mountains shows that 8200 years ago the California coast underwent 150 years of exceptionally wet and stormy weather. This is the first high resolution record of how the Holocene cold snap affected the California climate.

Watching cities grow

Earth & Climate - 星期二, 06/20/2017 - 21:31
Three million measurement points in one square kilometer: a world record has now been set in information retrieval from satellite data. Thanks to new algorithms, the researchers succeeded in making four-dimensional point clouds of Berlin, Las Vegas, Paris and Washington, D.C. from images stacks of the TerraSAR-X radar satellite. Next the scientists plan to create four-dimensional models of all cities in the world.
