9:47 PM | How Hot Is Your City?
You’ve probably heard about the urban heat island effect, but I bet you do not realize is how much it affects your weather (and how much it costs you in cooling costs). The folks at Climate Central put out a report this month that breaks down how large the temperature differences are between some cities, and the rural areas surrounding them. The report makes it obvious that we are paying a …

3:02 PM | Yawning wolves, face-mites and space-based lasers to fight global warming
Who’d Have Thunk It? 31.08.14 Do you ever get annoyed at having to wait for ages at border immigration? Well it could be that the time-consuming checks are not totally effective at matching photos to faces: A study on passport officers in Australia found that there was a ‘14% acceptance rate of ‘fraudulent photos’. Perhaps…

8:34 PM | Obama May Use Executive Power to Forge International Climate Change Deal as U.N. Draft Report Paints Stark Climate Picture
A leaked draft of a report by the United Nations Intergovernmental Panel on Climate Change (IPCC) warns that global warming is already affecting all continents and that additional pollution from heat-trapping gases will worsen the situation. “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the…

7:42 PM | Reduce, Reuse and Re-(bi)cycle
Audra Stark plans to pedal 300 miles from New York City to Washington, D.C., from Sept. 20-24 to raise money for The Earth Institute and other organizations working on the issues of climate, environment and transportation. “Too often I’ve found myself and others complaining about and debating an issue without taking action in our daily lives," she said. "Joining Climate Ride is one more way I can act on my lifelong concern about climate change, and take a further step on my personal […]

5:44 AM | The Stochastic Resonance Program (Part 2)
guest post by David Tanzer Last time we introduced the concept of stochastic resonance. Briefly, it’s a way that noise can amplify a signal, by giving an extra nudge that helps a system receiving that signal make the jump from one state to another. Today we’ll describe a program that demonstrates this concept. But first, […]

7:31 AM | Ship Noise Makes Young Eels Stressed and Vulnerable to Predation
Noise pollution in the ocean isn’t just a nuisance; it has grave consequences for the survival of some marine organisms. A recent study reveals that ship noises make young eels stressed and when confronted with predators, they are less likely to fend off attacks due to impaired escape behaviors, known as antipredator responses.  During exposure […]

7:04 PM | The Energy to Fight Injustice
The enormity of these anti-nuclear policy decisions is difficult to exaggerate. Energy consumption is an inescapable requirement of development, and renewable energy sources alone cannot satisfy the energy demands of China and other developing nations. They now have no choice but to burn massive amounts of coal if they wish to raise their living standards.

Originally posted on Azimuth:? Why do ostriches stick their heads under the sand when they’re scared? They don’t. So why do people say they do? A Roman named Pliny the Elder might be partially to blame. He wrote that ostriches “imagine, when they have thrust their head and neck into a bush, that the…

12:48 PM | Reflections of a Changing North
No one ever leaves the field the same way they entered it. Yes there is a new layer of mud on equipment, the expected wear and tear on your personal gear and your physical being, but that is not what I am referring to. I am acknowledging the intangible shift in perspective from a deepened understanding and a broadened vision that has been provided by the experience, and beyond that the questions that drive the next field campaign.

9:40 PM | Does the motion of the solar system affect our climate?
The Earth’s climate is believed to be affected, not just by people driving Humvees, but by a series of complex cycles, which can occur over a few years (such as El Nino) or even tens of thousands of years (changes in the Earth’s axis of rotation). But another cycle which may have an effect, lasts…

1:24 PM | Rising Ocean Acidity Weakens Hunting Ability in Sharks
Sharks, the ocean’s top predators, renowned for their impressive hunting abilities, rely extensively on their keen sense of smell to hunt prey located miles away—earning themselves the label “swimming noses.” But a new study reveals that high levels of seawater acidity expected due to climate change can diminish their ability to track prey through sensing […]

6:07 AM | El Nino Project (Part 7)
So, we’ve seen that Ludescher et al have a way to predict El Niños. But there’s something a bit funny: their definition of El Niño is not the standard one! Precisely defining a complicated climate phenomenon like El Niño is a tricky business. Lots of different things tend to happen when an El Niño occurs. […]

9:28 PM | Profiles In Courage
Republicans and global warming: In stark contrast to their party’s public stance on Capitol Hill, many Republicans privately acknowledge the scientific consensus that human activity is at least partially responsible for climate change and recognize the need to address the problem. However, they see little political benefit to speaking out on the issue… Anthony Adragna, […]

7:17 PM | Studies Find Climate Change to Disrupt Antarctic and Tropical Ecosystems
A recent study finds that West Antarctica’s ecosystem is highly correlated to its climate. As a result, climate change will have a negative impact on its ecological relationships, from plankton to penguins. Antarctica isn’t alone - climate change will also affect tropical ocean ecosystems by causing mass coral bleaching.
