In order to be a champion musher, you need dogs, sleds, a sense of athletic adventure and — oh, yeah — snow. Getting three out of four might work in baseball or basketball, but it just doesn’t count when it comes to the Iditarod , the 975-mile race that traditionally tests human and animal against Alaska’s elements.
Meteorologists are blaming an especially warm January, the third-warmest in the 96 years of records. The warmth melted snow, and not even the cold temperatures of February were able to make things right, leaving patches a dirty brown, rather than white, wonderland. The warm-to-cold cycle also created nasty ice and debris problems.
Here's a list of the mentions of climate change in the 2014 Quadrennial U.S. Dept of Defense Review ›
The Dept of Defense releases this report every four years as a way of articulating its strategic direction.
On March 7, 2014, Secretary of State John Kerry issued instructions to all diplomats around the world on combating climate change. He stressed that success in this effort will require active leadership and participation from everyone in the State Department and at posts around the world.
Personal Message From Secretary Kerry:
The environment has been one of the central causes of my life. I was just 26 when I participated in the very first Earth Day at home in Massachusetts. It was an eye-opening immersion into the power of grassroots action to force an issue onto the national radar screen and demand change. More than 20 million Americans—fully one-tenth of our country’s population at the time — came together to express a wake-up call. And they didn’t stop there. They elected a Congress that passed the Clean Air Act and the Clean Water Act and the first wave of legislation that set us on a path to change the face of the planet we share with the rest of humanity.
We can transform challenges into opportunities. I’ve seen it happen long before I had a vote in the Senate or an office in Foggy Bottom, and it’s what I still believe. But I’m not just waxing nostalgic. Protecting our environment and meeting the challenge of global climate change is a critical mission for me as our country’s top diplomat. It’s also a critical mission for all of you: our brave men and women on the frontlines of direct diplomacy.
Here’s what this guidance means in practice:
I. Lead by example through strong action at home and abroad: Making significant progress in combating climate change through domestic actions within the Department and at the federal, regional, and local level.
II. Conclude a new international climate change agreement: Working through the UN Framework Convention on Climate Change to negotiate a new, ambitious international climate agreement applicable to all countries by 2015 to take effect in 2020.
III. Implement the Global Climate Change Initiative: Undertaking a pragmatic, whole-of-government approach to speed the transition to a low-carbon, climate-resilient future, including (1) promoting clean energy solutions; (2) slowing, halting, and reversing emissions from land use; and (3) helping the most vulnerable countries strengthen climate resilience.
IV. Enhance multilateral engagement: Helping lead efforts including the Major Economies Forum, Clean Energy Ministerial, Montreal Protocol, and the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants.
V. Expand bilateral engagement: Engaging more than 50 partner countries on clean energy, sustainable landscapes, and adaptation, including the largest greenhouse gas emitters in the developing world.
VI. Mobilize financial resources: Working to mobilize and leverage billions of dollars of funding to transform our energy economies and promote sustainable land use, as well as working to limit public incentives for high-carbon energy production and fossil fuels.
VII. Integrate climate change with other priorities: Better integrating climate solutions into cross-cutting challenges, including women’s empowerment, urbanization, conflict and national security, and our own management and operations.- See more at: State.gov
How our brains fool us on climate, creationism, and the vaccine-autism link.
Consider a person who has heard about a scientific discovery that deeply challenges her belief in divine creation—a new hominid, say, that confirms our evolutionary origins. What happens next, explains political scientist Charles Taber of Stony Brook University, is a subconscious negative response to the new information—and that response, in turn, guides the type of memories and associations formed in the conscious mind. “They retrieve thoughts that are consistent with their previous beliefs,” says Taber, “and that will lead them to build an argument and challenge what they’re hearing.”
In other words, when we think we’re reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we’re being scientists, but we’re actually being lawyers (PDF). Our “reasoning” is a means to a predetermined end—winning our “case”—and is shot through with biases. They include “confirmation bias,” in which we give greater heed to evidence and arguments that bolster our beliefs, and “disconfirmation bias,” in which we expend disproportionate energy trying to debunk or refute views and arguments that we find uncongenial.That’s a lot of jargon, but we all understand these mechanisms when it comes to interpersonal relationships. If I don’t want to believe that my spouse is being unfaithful, or that my child is a bully, I can go to great lengths to explain away behavior that seems obvious to everybody else—everybody who isn’t too emotionally invested to accept it, anyway.
TL;DNR, but looks interesting.
“A lot of the time climate change doesn’t really seem tangible,” said lead author Scott Taylor, a postdoctoral researcher at the Cornell Lab of Ornithology. “But here are these common little backyard birds we all grew up with, and we’re seeing them moving northward on relatively short time scales.”
The birds moved so fast the scientists had to add an extra study site partway through their project in order to keep up.
In Pennsylvania, where the study was conducted, the hybrid zone is just 21 miles across on average. Hybrid chickadees have lower breeding success and survival than either of the pure species. This keeps the contact zone small and well defined, making it a convenient reference point for scientists aiming to track environmental changes.
“Hybridization is kind of a brick wall between these two species,” said Robert Curry, a professor of biology at Villanova University, who led the field component of the study. “Carolina Chickadees can’t blithely disperse north without running into black-caps and creating hybrids. That makes it possible to keep an eye on the hybrid zone and see exactly how the ranges are shifting.”
The researchers drew on field studies, genetic analyses, and crowdsourced bird sightings. The data was matched with winter temperatures observations, and the scientists also closely studied the birds’ DNA to pinpoint the distribution of the two species.
I like the idea that climate change will create new species through hybrids.
"Officials canceled two Olympic test events last February in Sochi after several days of temperatures above 60 degrees Fahrenheit and a lack of snowfall had left ski trails bare and brown in spots. That situation led the climatologist Daniel Scott, a professor of global change and tourism at the University of Waterloo in Ontario, to analyze potential venues for future Winter Games. His thought was that with a rise in the average global temperature of more than 7 degrees Fahrenheit possible by 2100, there might not be that many snowy regions left in which to hold the Games. He concluded that of the 19 cities that have hosted the Winter Olympics, as few as 10 might be cold enough by midcentury to host them again. By 2100, that number shrinks to 6.
The planet has warmed 1.4 degrees Fahrenheit since the 1800s, and as a result, snow is melting. In the last 47 years, a million square miles of spring snow cover has disappeared from the Northern Hemisphere. Europe has lost half of its Alpine glacial ice since the 1850s, and if climate change is not reined in, two-thirds of European ski resorts will be likely to close by 2100.
The same could happen in the United States, where in the Northeast, more than half of the 103 ski resorts may no longer be viable in 30 years because of warmer winters. As far for the Western part of the country, it will lose an estimated 25 to 100 percent of its snowpack by 2100 if greenhouse gas emissions are not curtailed — reducing the snowpack in Park City, Utah, to zero and relegating skiing to the top quarter of Ajax Mountain in Aspen.” NYTimes

A warmer Arctic could permanently affect the pattern of the high-altitude polar jet stream, resulting in longer and colder winters over North America and northern Europe, US scientists say. The jet stream, a ribbon of high altitude, high-speed wind in northern latitudes that blows from west to east, is formed when the cold Arctic air clashes with warmer air from further south. The greater the difference in temperature, the faster the jet stream moves.
According to Jennifer Francis, a climate expert at Rutgers University, the Arctic air has warmed in recent years as a result of melting polar ice caps, meaning there is now less of a difference in temperatures when it hits air from lower latitudes. “The jet stream is a very fast moving river of air over our head, but over the past two decades the jet stream has weakened. This is something we can measure,” she said Saturday at a meeting of the American Association for the Advancement of Science. As a result, instead of circling the earth in the far north, the jet stream has begun to meander, like a river heading off course. This has brought chilly Arctic weather further south than normal, and warmer temperatures up north. Perhaps most disturbingly, it remains in place for longer periods of time.

I have a feeling this was taken out of context.
President Obama’s new Executive Order, “Preparing the United States for the Impacts of Climate Change,” and recent Climate Action Plan directs federal agencies to ask the Climate Question and provide policy support and technical assistance to help federal, state and local governments, and private companies answer both parts of the Question — mitigation and adaptation.
The nexus between adapting to a changing climate and reducing GHGs is rarely approached in an integrated fashion. Many climate adaptation measures have GHG mitigation benefits and vice versa, yet too often the synergies only receive cursory attention. CCAP sees great opportunities in focusing on that sweet spot in the center of the Venn diagram.
The European Union, which for years has sought to lead the world in addressing climate change, is tempering its ambitions and considering turning mandatory targets for renewable energy into just goals.
The union’s policy-making body is also unlikely to restrict exploration for shale gas using the disputed technique known as hydraulic fracturing.
A deep and lasting economic slowdown, persistently high prices for renewable energy sources and years of inconclusive international negotiations are giving European officials second thoughts about how aggressively to remake the Continent’s energy-production industries.
The details are still being negotiated in Brussels, but officials said the European Commission’s energy and climate proposal will probably include a binding target of reducing emissions by 35 percent to 40 percent by 2030. Some officials wanted to make the new targets for renewable energy nonbinding. But opposition this week appears to have turned the tide in favor of having a binding renewable target — although it would be applied across the European Union rather than to individual nations, according to an official briefed on the negotiations.
There is absolutely no way to reasonably stop countries from emitting carbon and GHGs.
Pretty good overview. Has nice charts.

Wielicki noted that coastal areas are particularly vulnerable because of rising sea levels. Yet, the coastal population is increasing by 1,000,000 people per year. Many of these areas have key infrastructure such as ports, military bases, power plants and tourism.
- The U.S. average temperature has increased by about 1.5 degrees Fahrenheit since 1895, with more than 80 percent of the increase occurring since 1980.
- Extreme weather and climate events have risen in recent decades, with “new and stronger evidence” that many of these increases are related to human activities.
- Climate change impacts already are evident and expected to become “increasingly challenging” across the U.S. through this century and beyond.
- Climate change threatens human physical and mental health in many ways due to rising extreme weather events, wildfires, degrading air quality, disease transmitted by insects, food and water.
