Renewable energy investment and deployment is paying off, and in spades, when it comes to addressing a basic issue plaguing developed and developing countries alike: an inability to generate jobs that pay a good living wage. Around the world, renewable energy job creation continues to far outpace that for economies overall. Some 7.7 million people are now employed across the global renewable energy value chain, according to the International Renewable Energy Agency (IRENA). That’s up 18 percent from 6.5 million in 2014, the agency noted in its 2015 Renewable Energy and Jobs Annual Review.

Will climate change make the U.S. Midwest drier or wetter during the summer growing season? A new Dartmouth-led study finds that the answer remains uncertain.

The findings are important given the Midwest's agricultural output is critical to the U.S. economy and global food security.

The study appears in the journal Water Resources Research. The study included researchers from Dartmouth College, Columbia University, National University of Singapore and Massachusetts Institute of Technology.

Iniciado en 2006, el Día de las Especies en Peligro de Extinción es "una celebración de la vida silvestre y los lugares salvajes" con la intención de promover la "importancia de la protección de las especies en peligro de extinción y las acciones de todos los días que la gente puede tomar para ayudar a protegerlos".

Cada año, el tercer viernes de mayo, y durante todo el mes, zoológicos, acuarios, parques, jardines botánicos, refugios de vida silvestre, museos, escuelas, centros comunitarios, grupos conservacionistas y otras organizaciones tienen excursiones, presentaciones de conferencistas, exposiciones para niños y más para conmemorar el Día.

U.S. residents' exposure to extreme heat could increase four- to six-fold by mid-century, due to both a warming climate and a population that's growing especially fast in the hottest regions of the country, according to new research. The study, by researchers at the National Center for Atmospheric Research (NCAR) and the City University of New York (CUNY), highlights the importance of considering societal changes when trying to determine future climate impacts.

The last several decades have brought a global explosion of electronics with a huge impact on quality of life and communications, as well as the world economy.

But, like most big human-induced changes, there were unintended consequences, primarily in the form of the mountains of waste that resulted as products quickly became obsolete and tossed out only to be replaced by others with an equally short lifespan. (One study showed that 25 percent of electronic devices were used less than 500 hours before being discarded.) This is exacerbated by the fact that electronic waste can contain dangerous materials including lead, mercury and cadmium.
