Milder winters have led to earlier growing seasons and noticeable effects on the breeding habits of some predatory birds, according to research by Boise State biologists Shawn Smith and Julie Heath, in collaboration with Karen Steenhof, and The Peregrine Fund’s Christopher McClure. Their work was recently published in the Journal of Animal Ecology under the title “Earlier nesting by generalist predatory bird is associated with human responses to climate change.”

It turns out bird poop helps cool the Arctic.

That’s according to new research from Colorado State University atmospheric scientists, who are working to better understand key components of Arctic climate systems.

Rudy Boonstra has been doing field research in Canada’s north for more than 40 years.

Working mostly out of the Arctic Institute’s Kluane Lake Research Station in Yukon, the U of T Scarborough biology professor has become intimately familiar with Canada’s vast and unique boreal forest ecosystem.

But it was during a trip to Finland in the mid-1990s to help a colleague with field research that he began to think long and hard about why the boreal forest there differed so dramatically from its Canadian cousin. This difference was crystallized by follow-up trips to Norway.

Heartbreaking stories of seabirds eating plastic — and the accompanying horrible images— are everywhere, but now scientists are an important question: Why do seabirds eat plastic in the first place? And why are some more likely to have bellies full of plastic than others?

The answer, it turns out, lies in a compound called dimethyl sulfide, or DMS, which emits a “chemical scream” that some birds associate with food. When seabirds find chunks of plastic bobbing in the water, they gobble them up, not realizing that they’ve just consumed something very dangerous.

Most studies of global climate change attempt to predict what might happen to the Earth as temperatures rise in future.  A new study representing an international collaboration by ecologists and conservation biologists shows that global changes in climate have already impacted every aspect of life on Earth, from genes to entire ecosystems. It was published in the prestigious journal Science on November 10, 2016. 

The research team, led by the University of Florida and with participation from the University of Hong Kong, showed that of a total of 94 ecological processes evaluated globally, 82% of them showed evidence of impact from climate change.  Land, freshwater and marine ecosystems and species have all been all affected, and consequential impacts on people could range from increased pests and disease outbreaks, to unpredictable changes in fisheries and decreasing agriculture yields. 

Climate change has already impacted nearly every aspect of life on earth, according to a new study in the journal Science. Warming global temperatures have altered everything from entire ecosystems down to the individual genes of species. 

New findings suggest the rate at which CO2 is accumulating in the atmosphere has plateaued in recent years because Earth’s vegetation is grabbing more carbon from the air than in previous decades.

That’s the conclusion of a multi-institutional study led by a scientist from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). It’s based on extensive ground and atmospheric observations of CO2, satellite measurements of vegetation, and computer modeling. The research is published online Nov. 8 in the journal Nature Communications.

The hottest year on record globally in 2015 could be an average year by 2025 and beyond if carbon emissions continue to rise at the same rate, new research has found.

Lead author Dr Sophie Lewis from the ANU Fenner School of Environment and Society said human activities had already locked in this new normal for future temperatures, but immediate climate action could prevent record extreme seasons year after year.

Could birdwatching or monitoring tree blossoms in your community make a difference in global environmental research? A new study says yes: citizen scientists have a vital role to play.

Citizen scientists are already providing large amounts of data for monitoring biodiversity, but they could do much more, according to a new study published in the journal Biological Conservation, which suggests that citizen science has the potential to contribute much more to regional and global assessments of biodiversity. Citizen scientists are regular people who provide data or input to science, for example by monitoring species in their community or examining satellite imagery for evidence of deforestation or land use change. 

“Citizen scientists are already contributing enormously to environmental science,” says IIASA researcher Linda See. “For example, a huge amount of species occurrence data is provided by members of the interested public. The question we addressed was, where are citizens contributing and where are they not, and how can we draw on this phenomenon to help fill the gaps in science?”

Have you noticed fewer butterflies floating this year? Researchers in the UK think they know the culprit for the population decline: extreme weather conditions.
