El mes pasado, la concentración atmosférica de dióxido de carbono (CO2), medidas en la Isla de Amsterdam, en el sur del Océano Índico, superó por primera vez el valor simbólico de 400 ppm, o 0,04%. Las concentraciones de CO2 registradas en la estación de investigación de la Isla de Amsterdam son los más bajos en el mundo (excluyendo los ciclos estacionales), debido a la lejanía de la isla a partir de fuentes antropogénicas.
China tiene la oportunidad de aumentar masivamente su uso de energía eólica…si integra adecuadamente el viento en su sistema de energía existente, de acuerdo con un nuevo estudio. Las investigaciones pronostican que la energía eólica podría proporcionar el 26 por ciento de la demanda eléctrica proyectada de China en 2030, por encima del 3 por ciento del 2015.
By the 2080s, as many as 3,331 people could die every year from exposure to heat during the summer months in New York City. The high estimate by Columbia University scientists is based on a new model--the first to account for variability in future population size, greenhouse gas trajectories, and the extent to which residents adapt to heat through interventions like air conditioning and public cooling centers. Results appear online in the journal Environmental Health Perspectives.

A major climate event millions of years ago that caused substantial change to the ocean's ecological systems may hold clues as to how the Earth will respond to future climate change, a Florida State University researcher said.
In a new study published in Earth and Planetary Science Letters, Assistant Professor of Geology Jeremy Owens explains that parts of the ocean became inhospitable for some organisms as the Earth's climate warmed 94 million years ago. As the Earth warmed, several natural elements -- what we think of as vitamins -- depleted, causing some organisms to die off or greatly decrease in numbers.
