Si los cientÃficos quieren que el público confÃe en sus sugerencias de investigación, es posible que quieran parecer un poco más "cálidos", según un nuevo estudio publicado por la Escuela Woodrow Wilson de Asuntos Públicos e Internacionales de la Universidad de Princeton, EEUU. El estudio, publicado en las Actas de la Academia Nacional de Ciencias (PNAS), muestra que mientras los estadounidenses ven a los cientÃficos como competentes, creen que no son de confianza por completo. Esto puede ser debido a que no se perciben como amables o cálidos.

A global low-carbon energy economy is not only feasible - it could actually double electricity supply by 2050, while also reducing air and water pollution, according to new research. Even though photovoltaic power requires up to 40 times more copper than conventional power plants, and wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy. These positive findings are published in the Proceedings of the National Academy of Sciences by Edgar Hertwich and Thomas Gibon, of the Norwegian University of Science and Technology Department of Energy and Process Engineering.

Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.
