Para fines de 2017, se prevé que las emisiones mundiales de dióxido de carbono procedentes de combustibles fósiles y de la industria aumentarán aproximadamente un 2% en comparación con el año anterior, con un rango de incertidumbre entre el 0,8% y el 3%. Las noticias surgen después de tres años de emisiones manteniéndose relativamente planas.
By the end of 2017, global emissions of carbon dioxide from fossil fuels and industry are projected to rise by about 2% compared with the preceding year, with an uncertainty range between 0.8% and 3%. The news follows three years of emissions staying relatively flat.
Exposure to air pollution is associated with osteoporosis-related loss of bone mineral density and risk of bone fractures, according to a new study by researchers at Columbia University’s Mailman School of Public Health. Their findings are published in The Lancet Planetary Health.
Songbirds exposed to widely used insecticides during migration pit stops on farmland could lose significant body weight and become disoriented, research by York University and the University of Saskatchewan (U. of S.) has found.
The researchers exposed white-crowned sparrows on spring migration to realistic doses of two different insecticides – imidacloprid, a neonicotinoid, and chlorpyrifos, an organophosphate – to see the effects on migratory activity, orientation and body mass.
Whilst it is widely accepted that sea level is rising because of the melting of the massive sheets covering Greenland and Antarctica, a new paper in the Journal of Geophysical Research: Oceans, by scientists at Bangor University in collaboration with Harvard and Oregon State Universities in the US, and McGill University in Canada, shows that the impact of the melting of these ice sheets will go far beyond just changing water levels. It could have further reaching impacts on global climate.
A targeted expansion of climate observing systems could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits, according to a new paper published today in the online journal Earth’s Future. Better observations would provide decision makers information they need to protect public health and the economy in the coming decades, the scientists say.
Venkatachalam Ramaswamy, director of NOAA’s Geophysical Fluid Dynamics Laboratory, said that improving our ability to predict and plan for droughts, floods, extreme heat events, famine, sea level rise and changes in freshwater availability is likely to yield significant savings each year.
