Slow earthquakes occur continuously in the Alaska-Aleutian subduction zone

Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that “slow earthquakes” are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the boundary between tectonic

London startup Bulb to convince people to switch to renewable energy

London startup Bulb has a bigger aim than trying to convince people to download an app: It's trying to rethink how energy suppliers work. Bulb is a green energy supplier, with all of its electricity and 10% of its gas coming from renewable sources. The company says it now has 70,000 customers. Cofounder Hayden Wood

Disappearance of species tells only part of the story of human impact

In the first such global evaluation, Stanford biologists found more than 30 percent of all vertebrates have declining populations. They call for curbs on the basic drivers of these losses. See video here. By Rob Jordan No bells tolled when the last Catarina pupfish on Earth died. Newspapers didn’t carry the story when the Christmas

Climate change to deplete some US water basins used for irrigation

A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation. The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this

Climate inequalities are moving from North-South to urban-rural

Cities have been recognized as key drivers toward the successful governance of resources and as the front line in combating climate change. But the economic divide between the Global North and South that historically has shaped debates on urbanization and climate change could soon be overshadowed by inequalities related to a potentially stronger disparity between

Climate change could exacerbate economic inequalities in the U.S.

Climate change may make the rich richer and the poor poorer in the United States. Counties in the South face a higher risk of economic downturn due to climate change than their northern counterparts, a new computer simulation predicts. Because southern counties generally host poorer populations, the new findings, reported in the June 30 Science,

Solar paint offers endless energy from water vapor

Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen – the cleanest source of energy. The paint contains a newly developed compound that acts like silica gel, which is used in sachets to absorb moisture and keep food, medicines and electronics fresh and dry. But unlike silica

Reconciling predictions of climate change

Harvard University researchers have resolved a conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere. That conflict -- between temperature ranges based on global climate models and paleoclimate records and ranges generated from historical observations -- prevented the United Nations' Intergovernmental Panel on

Fundraising for Renewable Resources Exceeds Conventional Energy

Investor interest in renewable energy is swelling less than two years after the Paris Agreement was signed to protect the environment globally. Renewables-focused funds have raised $5 billion this year, outstripping fundraising targeting conventional energy for the first time, according to a Preqin report Wednesday. Fundraising for conventional energy has fallen significantly from its $38

Exposure to neonic pesticides results in early death for honeybee workers and queens

Worker and queen honeybees exposed to field realistic levels of neonicotinoids die sooner, reducing the health of the entire colony, biologists have found. The researchers were also surprised to find that the neonicotinoid contaminated pollen collected by the honeybees came not from crops grown from neonicotinoid treated seeds, but plants growing in areas adjacent to

Tiny “motors” are driven by light

Science fiction is full of fanciful devices that allow light to interact forcefully with matter, from light sabers to photon-drive rockets. In recent years, science has begun to catch up; some results hint at interesting real-world interactions between light and matter at atomic scales, and researchers have produced devices such as optical tractor beams, tweezers,

Future of impact, climate investor one, India’s development impact bond, Big Renewables

‘Future of impact’ requires investment, philanthropy — and business as a force for good. As Bill Gates says, “We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten.” For its 10th anniversary last month, Liquidnet For Good hosted “The Future of Impact” forum to

Air pollution casts shadow over solar energy production

Global solar energy production is taking a major hit due to air pollution and dust. According to a new study, airborne particles and their accumulation on solar cells are cutting energy output by more than 25 percent in certain parts of the world. The regions hardest hit are also those investing the most in solar

New Evidence for Past Large Earthquakes in the Eastern Tennessee

The Eastern Tennessee Seismic Zone (ETSZ), a zone of small earthquakes stretching from northeastern Alabama to southwestern Virginia, may have generated earthquakes of magnitude 6 or greater within the last 25,000 years, according to a study published in the Bulletin of the Seismological Society of America.The ETSZ is the second-most active natural seismic zone in

New Danish Invention Cleans Water with Sunlight

Two Danish students have developed “SolarSack” for inexpensive and environmentally friendly water purification. The concept was tested in villages, refugee camps and slums in East Africa where it will be marketed. Anders Løcke and Louise Ullmann, who study Architecture and Design at Aalborg University (AAU), have designed a better and cheaper system for purifying drinking

New Flood Study Reveals America’s Most Vulnerable Communities

BATON ROUGE – 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 at LSU have gathered valuable information on flood hazard, exposure and vulnerability in counties throughout the U.S. They studied development trends from 2001

How the climate can rapidly change at tipping points

During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland – as indicated by new climate calculations from researchers at the Alfred Wegener Institute and the University of Cardiff. Their study is the
