Effect of climate change on human morbidity and mortality and sea levels
by Sarah Stephen in An ecological oratorio
Climate change has been resulting in quite a many detrimental manifestations which tend to have a domino effect: fluctuations in temperature and precipitation (resulting in climate variability), as well as extreme manifestations such as drought, storms, rise in sea levels, and frequent severe weather events.Consider the research by Grinsted et al (2009) who used a ‘physically plausible four parameter linear response equation’ to relate nearly 2,000 years of global temperatures and sea level.........

Ecosystem functions breaking down from climate change
by CJA Bradshaw in ConservationBytes
I’m particularly proud to present to ConservationBytes.com readers a new paper we’ve just had published online in Journal of Animal Ecology: Mechanisms driving change: altered species interactions and ecosystem function through global warming (Lochran Traill, Matt Lim, Navjot Sodhi and me). It wasn’t easy to write a review discussing climate change effects on biodiversity, mainly [...]... Read more »

Climate change drying up streams, reducing the reproductive success of bats in the Rockies
by Jeremy in Voltage Gate
Bats, as this article in Ecology explains, are particularly sensitive to these changes and, due to their enormous numbers, are integral to food webs as predator and prey. They may be that indicator ecologists are looking for.... Read more »

Laser guide stars as magnetometers
by sarah in SarahAskew
In a nice piece of cross-pollination between disciplines, scientists have proposed a new method for measuring the Earth’s magnetic field strength using technology developed for ground-based observational astronomy. As it turns out, the laser guide stars astronomers use to sense the turbulence high up in the atmosphere can be used as cheap and efficient magnetometers.
To [...]... Read more »

The link between rainfall intensity and global temperature
by Dr Dave in Dave's Landslide Blog
The aftermath of a landslide in Taiwan caused by very heavy rainfallOne of the most interesting aspects of the global landslide database that we maintain at Durham is the way in which it has highlighted the importance of rainfall intensity in the triggering of fatal landslides. Generally speaking, to kill people a landslide needs to move quickly rapid, and rapid landslides appear to be primarily (but note not always) triggered by intense rainfall events (indeed in the reports the term "cloudbur........

How Big (Dead) Mammals Respond(ed) to Global Warming: Paleontology and Our Climate Crisis
by Andrew Farke in The Open Source Paleontologist
After all of the commotion over "Ida," I'm happy to point out a new, thought-provoking paper in PLoS ONE that perhaps has more relevance to modern humans than any old primate of debated affinity. This new contribution ties two rather cool issues together: charismatic megafauna and global warming. And what might they have to do with each other?Within the scientific community, our current cycle of climate change ("global warming") is pretty well-supported by numerous lines of evidence. In light of........ Read more »

Fire and the changing world
by Marc Cadotte in The EEB and flow
This is probably the most appropriate blog I have ever written. My family and I were evacuated two weeks ago because of the Jesusita fire in Santa Barbara, and several homes in our neighborhood were lost. Here in Santa Barbara we have experienced multiple years of extremely large fires, with this last one occurring much earlier than previous fires.Wildfires have been a part of the Earth’s biota likely since organisms first died and dried on land. Ecosystems have been shaped by fire, numerous o........ Read more »

Seabirds: ‘Climate change is here’
by Katie Kline in EcoTone
To convince naysayers that climate change is real, maybe all we need to tell them is to look up in the sky - or down into the ocean. Two recent studies show that seabirds can be important sentinels of a changing climate.
Says Dee Boersma, University of Washington ecologist and one of the world’s penguin experts, [...]... Read more »

Salamaders and climate change -impending extinctions?
by Marc Cadotte in The EEB and flow
By the now the evidence of a global frog decline, perhaps even an extinction crisis, has been well documented. But what about salamanders? They are normally less abundant and less-studied compared to frogs, but is there evidence of the same general pattern of declining population sizes? According to Sean Rovito and colleagues, the answer is unfortunately yes. They repeated a plethodontid (lungless) salamander survey done in the 1970’s in Central America and found that many species have decline........ Read more »

We can make it better
by Kent in Uncommon Ground
The news on climate change is more than a little depressing. The IPCC Synthesis Report projects that by 2100 the global average temperature will be at least 2.5°F higher than in 1980-1999, and the most likely outcome is for 3.5°-7.0°F...... Read more »
