Scientists are not exactly sure why the whales are dying, but in a newly released study, published in the journal Marine Ecology Progress Series, researchers conclude it is likely a result of starvation due lack of prey, perhaps caused by warming Arctic waters where they feed. If that’s true, the concern is that mass die-offs like this may become more frequent in the future as waters continue to heat up due to human-caused climate change.
A new report has found that the UK’s wildlife is continuing to crash, with hundreds of species now at risk of disappearing from our shores altogether.
Over the past 50 years, urbanisation, agriculture, pollution and climate change have all caused the nation’s plants and animals to dwindle – a trend that has continued unabated within the last decade despite efforts to reverse these losses.
The number of bee species recorded worldwide has been sharply decreasing since the 1990s.
Eduardo Zattara and Marcelo Aizen at the National University of Comahue in Argentina analysed how many wild bee species are observed each year as recorded in the Global Biodiversity Information Facility – a publicly available platform where researchers and citizens can record sightings of bee species.
In the 2015 international Paris Climate Agreement, nearly every country [see editor’s note] agreed to try and limit global warming to no more than 2 degrees Celsius (3.6 degrees Fahrenheit) and preferably closer to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial temperatures. Achieving these goals will require dramatic changes, as the world has already warmed 1 degree Celsius (1.8 degrees Fahrenheit), and temperatures, fossil fuel consumption, and carbon pollution all are continuing to rise.
Producers have limits on how far they can reduce impacts. Most strikingly, impacts of the lowest-impact animal products typically exceed those of vegetable substitutes, providing new evidence for the importance of dietary change.
