Los parques eólicos marinos que van a ser construidos en aguas de todo el Reino Unido podrían suponer una amenaza mayor de lo que se pensaba para las poblaciones protegidas de alcatraces, según una investigación dirigido por la Universidad de Leeds.

Antes se pensaba que los alcatraces, que se reproducen en el Reino Unido entre abril y septiembre de cada año, por lo general volaban muy por debajo de la altura mínima de 22 metros sobre el nivel del mar barridas por las aspas de las turbinas eólicas en el mar.

The revelations that Volkswagen, the world's second largest car manufacturer, had routinely gamed US emissions testing has thrown the spotlight on the environmental and health impact of cars.

EPA today confirmed that New Englanders experienced a slight increase in the number of unhealthy air quality days this year, compared to 2014 and 2013.

Based on preliminary data collected between April and September 2015, there were 24 days when ozone monitors in New England recorded concentrations above levels considered healthy. By contrast, in 2014 there were a total of 9 unhealthy ozone days, and in 2013 there were a total of 20 such days.

The number of unhealthy ozone days in each state this summer is as follows:
- 22 days in Connecticut (compared to 8 in 2014, and 18 in 2013)
- 4 days in Rhode Island (0 in 2014, and 7 in 2013)

Offshore wind farms which are to be built in waters around the UK could pose a greater threat to protected populations of gannets than previously thought, research led by the University of Leeds says.

It was previously thought that gannets, which breed in the UK between April and September each year, generally flew well below the minimum height of 22 metres above sea level swept by the blades of offshore wind turbines.
