Decline in Species Shows Climate Change Warnings Not Exaggerated

One in 10 species could face extinction by the year 2100 if current climate change impacts continue.

This is the result of University of Exeter research, examining studies on the effects of recent climate change on plant and animal species and comparing this with predictions of future declines.

Published in leading journal Proceedings of the National Academy of Sciences, the study uses the well-established IUCN Red List for linking population declines to extinction risk. The research examines nearly 200 predictions of the future effects of climate change from studies conducted around the world, as well as 130 reports of changes which have already occurred. (more…)

Evaluation of Climate Policy Rocketing But in an Undeveloped and Unsystematic Way

*New research led by the University of East Anglia and the VU University Amsterdam shines new light on the little studied but politically vital practices of climate policy evaluation in Europe.*

Published in the international journal Policy Sciences, a meta-analysis by a team of researchers from across Europe offers the very first systematic cataloging of the emerging patterns of policy evaluation undertaken in different parts of the European Union.

In the last decade or so the politics surrounding the development of new policies has attracted unprecedented attention. Many new targets and policies have been adopted. But a lot less is known about what is being done to check that the resulting policies are actually delivering on their promises. (more…)

Where Have All the Flowers Gone?

*High-mountain wildflower season reduced, affecting pollinators like bees, hummingbirds*

It’s summer wildflower season in the Rocky Mountains, a time when high-peaks meadows are dotted with riotous color.

But for how long?

Once, wildflower season in montane meadow ecosystems extended throughout the summer months. But now scientists have found a fall-off in wildflowers at mid-season. (more…)

With Global Warming, Arctic Access Will Diminish By Land But Improve By Sea

Global warming over the next 40 years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others, a new UCLA study predicts.

“As sea ice continues to melt, accessibility by sea will increase, but the viability of an important network of roads that depend on freezing temperatures is threatened by a warming climate,” said Scott Stephenson, a UCLA graduate student in geography and the study’s lead author. (more…)

Clouds, a Weapon Against Climate Change?

University of Georgia researchers define a missing link in how clouds are formed

Some clouds cool the earth. But how are these clouds formed? How does the chemistry of the ocean affect their formation? Is this process affected by climate change? Can humans affect cloud formation to increase the cooling effect of clouds, having positive implications for the health of the planet? (more…)

Uncertain Future for Joshua Trees Projected with Climate Change

FLAGSTAFF, Ariz. — Temperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new study led by U.S. Geological Survey ecologist Ken Cole.

The research team used models of future climate, an analysis of the climatic tolerances of the species in its current range, and the fossil record to project the future distribution of Joshua trees. The study concludes that the species could be restricted to the northernmost portion of its current range as early as the end of this century. Additionally, the ability of Joshua trees to migrate via seed dispersal to more suitable climates may be severely limited. (more…)
