If it seems like you're pulling more bass than trout out of Ontario's lakes this summer, you probably are.

Blame it on the ripple effect of climate change and warming temperatures. Birds migrate earlier, flowers bloom faster, and fish move to newly warmed waters putting local species at risk.

To mitigate the trend and support conservation efforts, scientists at the University of Toronto (U of T) are sharing a way to predict which plants or animals may be vulnerable to the arrival of a new species.

El condado rural de Tulare, California, está siendo llamado el epicentro de esta sequía.

Eso es porque al menos 1,300 pozos residenciales se han secado, lo que afecta al menos a 7.000 personas. Cuando sus grifos comienzan a entregar aire aquí, usted llama a Paul Boyer y su equipo.

Bajo un castigador sol de media tarde, Boyer descarga hasta cinco de estos tanques de agua de 200 litros de una plataforma. Él ayuda a ejecutar una organización no lucrativa local que está a cargo de la distribución de estos tanques de agua de 2,500 galones, a víctimas de la sequía.

According to a new study published in Nature Geoscience, the Greenland ice sheet has been shown to accelerate in response to surface rainfall and melt associated with late-summer and autumnal cyclonic weather events.

Samuel Doyle and an international team of colleagues led from Aberystwyth University's Centre for Glaciology combined records of ice motion, water pressure at the ice sheet bed, and river discharge with surface meteorology across the western margin of the Greenland ice sheet and captured the wide-scale effects of an unusual week of warm, wet weather in late August and early September, 2011.

A collection of fossilized owl pellets in Utah suggests that when the Earth went through a period of rapid warming about 13,000 years ago, the small mammal community was stable and resilient, even as individual species changed along with the habitat and landscape. By contrast, human-caused changes to the environment since the late 1800s have caused an enormous drop in biomass and “energy flow” in this same community, researchers reported today in Proceedings of the National Academy of Sciences.

Global air travel contributes around 3.5 percent of the greenhouse forcing driving anthropogenic climate change, according to the International Panel on Climate Change (IPCC). But what impact does a warming planet have on air travel and how might that, in turn, affect the rate of warming itself? A new study by researchers at the Woods Hole Oceanographic Institution and University of Wisconsin Madison found a connection between climate and airline flight times, suggesting a feedback loop could exist between the carbon emissions of airplanes and our changing climate. The study was published today in Nature Climate Change.

Una investigación de la University of British Columbia (UBC) muestra que las poblaciones de aves marinas monitoreadas en el mundo, han caído 70 por ciento desde la década de 1950, una indicación cruda de que los ecosistemas marinos no están bien.

Michelle Paleczny, estudiante de maestría de la UBC e investigadora en el proyecto Sea Around Us, y co-autores, recopilaron información sobre más de 500 poblaciones de aves marinas de todo el mundo, lo que representa 19 por ciento de la población global de aves marinas. Encontraron que, en general, las poblaciones habían disminuido en un 69,6 por ciento, lo que equivale a una pérdida de cerca de 230 millones de aves en 60 años.
