Scientists generate heat over 1,000 degrees Celsius with solar power instead of fossil fuel      (via sciencedaily.com)     Original source 

Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000 C (1,832 F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.

The case for sharing carbon storage risk      (via sciencedaily.com)     Original source 

Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.

90% of Floridians believe climate change is happening      (via sciencedaily.com)     Original source 

The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.

Transforming waste carbon dioxide into high-value chemicals with a cost reduction of about 30%      (via sciencedaily.com)     Original source 

A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional approach of using high-purity CO2 for electrochemical reduction processes, achieving significant cost savings of about 30%.

Researchers discover the universe's oldest stars in our own galactic backyard      (via sciencedaily.com)     Original source 

Astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way's 'halo' -- the cloud of stars that envelopes the entire main galactic disk -- and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape.

Island birds more adaptable than previously thought      (via sciencedaily.com)     Original source 

The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.

The price tag of phasing-out coal      (via sciencedaily.com)     Original source 

Coal phase-out is necessary to solve climate change, but can have negative impacts on workers and local communities dependent on coal for their livelihoods. Researchers have studied government plans for coal phase-out around the world and discovered that more than half of such plans include monetary compensation to affected parties. This planned compensation globally amounts to USD 200 billion, but it excludes China and India, the two largest users of coal that currently do not have phase-out plans. The study shows that if China and India decide to phase out coal as fast as needed to reach the Paris climate targets and pay similar compensation, it would cost upwards of USD 2 trillion.
