As the planet warms faster, more species will be increasingly at risk
Apr 21st
The acceleration of change means that the species inhabiting each zone have less time to adapt to the climatic changes, said lead author Irina Mahlstein, a CIRES scientist who works at NOAA’s Earth System Research Laboratory in Boulder, Colo. “The warmer the climate gets, the faster the climate zones are shifting. This could make it harder for plants and animals to adjust.”
The study is the first to look at the accelerating pace of the shifting of climate zones, which are areas of the Earth defined by annual and seasonal cycles of temperature and precipitation, as well as temperature and precipitation thresholds of plant species. Over 30 different climate zones are found on Earth; examples include the equatorial monsoonal zone, the polar tundra zone and cold arid desert zone.
“A shift in the climate zone is probably a better measure of ‘reality’ for living systems, more so than changing temperature by a degree or precipitation by a centimeter,” said Mahlstein.
The scientists used climate model simulations and a well-known ecosystem classification scheme to look at the shifts between climate zones over a two-century period, 1900 to 2098. The team found that for an initial 3.6 degrees Fahrenheit of warming, about 5 percent of Earth’s land area shifts to a new climate zone.
The models show that the pace of change quickens for the next 3.6 F of warming as an additional 10 percent of the land area shifts to a new climate zone. The paper was published online in the journal Nature Climate Change on April 21.
Certain regions of the globe, such as northern middle and high latitudes, will undergo more changes than other regions, such as the tropics, the scientists found. In the tropics, mountainous regions will experience bigger changes than low-altitude areas.
In the coming century, the findings suggest that frost climates — the coldest climate zone of the planet — will largely decrease. In general, dry regions in different areas of the globe will increase, and a large fraction of land area will change from cool summers to hot summers, according to the study.
The scientists also investigated whether temperature or precipitation had a greater impact on how much of the land area changed zones. “We found that temperature is the main factor, at least through the end of this century,” said Mahlstein.
John Daniel at the NOAA Earth System Research Laboratory and Susan Solomon at the Massachusetts Institute of Technology co-authored the study.

Boulder County: There’s still $$$ available to help with heating bills
Mar 29th
More may be eligible, with the expansion of heating assistance program , but applications are due by the end of April.
There is still time for Boulder County residents to apply for winter heating assistance through the Low-Income Energy Assistance Program (LEAP),
LEAP helps low-income residents who meet income criteria and other eligibility factors pay their winter heating bills. The program is designed to pay the highest benefit to households with the highest heating costs.
“Energy costs have continued to increase throughout the recent economic downturn,” said Theresa Kullen, an eligibility manager with Boulder County Department of Housing and Human Services (BCDHHS). “We want to make sure that people know this help is available, because it can make the difference between whether or not someone can also afford groceries or a visit to the doctor in a given month.”
In addition, Boulder County residents who may not have previously qualified for heating assistance may now be eligible. The Boulder County Department of Housing and Human Services (BCDHHS) continues to oversee local expansions of the Heating Assistance Program and can provide help for households with income limits higher than those in LEAP.
Boulder County residents who were previously ineligible for LEAP due to income limit reductions may now qualify for help with heating bills through the Heating Plus program. This new program has gross monthly income limits of 185 percent of the Federal Poverty Level (for a family of three, this amounts to about $3,000 per month).
Those who want to find out more about whether they qualify or want to apply for the assistance should email Erica Penz at Boulder County LEAP, or call 303-682-6783. Boulder County will continue to accept applications through April 30, 2013.

CU Boulder study: More power leads to more dehumanization (No sh*t, Sherlock)
Mar 6th
“I think a lot of us have the intuition that some powerful people can be pretty dehumanizing,” said Jason Gwinn, a doctoral student in the Department of Psychology and Neuroscience and lead author of the study. “But our goal was to test if power, when randomly assigned to ordinary students, would have that effect. That would say something about power itself rather than about the sort of people who have the drive to take power.”
The researchers enlisted about 300 CU-Boulder students taking an introductory psychology course to participate in two experiments. In the first experiment, students were assigned to be either a manager or an assistant for a mock hiring task. The assistants were asked to review resumes for an open job and then list the strengths and weaknesses of each applicant. The managers then reviewed the list made by their assistants and made a final decision about whom to hire.
In the second experiment, participants were asked to play a game and were assigned to be either an allocator or a recipient. For the game, one allocator and one recipient were tasked with splitting a pot of money. The allocator, the higher-power role, made the first offer, suggesting how the money be split. If the recipient, the lower-power role, accepted the offer, both people received their share of the money. If the recipient declined the offer, neither person received any of the money.
At the end of each experiment, the participants were asked to rate each other on 40 traits. The result was that students in higher-power roles assigned fewer uniquely human traits to the students in lower-power roles than vice versa. Examples of traits considered to be more uniquely human, as defined and tested in a 2007 Australian study, include being ambitious, imaginative, frivolous and insecure. Examples of traits that are less uniquely human — those that could be used to describe a pet as well as a friend, for example — include being passive, timid, friendly and shy.
The question of whether power leads to dehumanization has part of its roots in the renowned Stanford Prison Experiment conducted in 1971. Twenty-four male students were randomly assigned to play the role of either inmate or guard in a mock prison in the basement of the Stanford psychology building. During the study, the guards were psychologically abusive to the prisoners, many of whom passively accepted the abuse, despite the fact that the participants knew that they were all students at the same elite university.
Though the guards were described as dehumanizing the prisoners, the term “dehumanization” was well defined at the time and the experiment was not designed to allow the researchers to confidently state that it was the increase in power that lead to the dehumanization. By contrast, Gwinn’s study, now available online, was designed specifically to test the relationship between power and dehumanization.
Gwinn cautions that the researchers cannot yet say whose perspective is being changed by the power differential imposed on participants in the CU study. It’s possible that being in a position of less power makes a person see those in power as more human rather than the other way around, or that both people are affected.
“We haven’t pinned down why this happens,” Gwinn said. “We don’t know whose perception is being affected.”
