WATCH: One Year After Sandy, Breezy Point Rebuilds

| Mon Oct. 28, 2013 3:00 AM PDT

One year ago tomorrow, storm surge from Hurricane Sandy set off a fire in Breezy Point, Queens, that leveled more than 100 homes. Now, construction is underway to rebuild the community from the ground up. But in July 2012, Congress decided to slash subsidies for federal flood insurance, and many residents now worry that rising rates could soon make this quiet beachside neighborhood unaffordable.

CHARTS: US Carbon Emissions Are Dropping

| Tue Oct. 22, 2013 12:41 PM PDT

One of the next big items on President Obama's green agenda is a new set of caps on greenhouse gas emissions from power plants. Set to roll out over the next few years, the rules aim to slash the climate impact of the nation's biggest polluters. But statistics released yesterday from the federal Energy Information Administration show that even without these new caps, energy-related carbon emissions—those that come from powering factories, homes, cars, and businesses—dropped almost four percent between 2011 and 2012, marking the fifth out of the last seven years for these emissions to decline:

For Climate Scientists, Shutdown Casts Long Shadow

| Fri Oct. 18, 2013 8:00 AM PDT
Antarctic researcher Gretchen Hoffman, left, says consequences of the shutdown "could completely scuttle some projects."

The government shutdown might be over, but for some climate scientists the headache is just beginning. During the shutdown, National Science Foundation-funded research facilities in Antarctica—where some of the world's most important climate research takes place—were left with a skeleton staff at just the time of year they would normally be coming back to life after a long, dark winter.

On its first day back online, NSF released a statement saying it would salvage the research season "to the maximum extent possible," without giving a definite timeline. NSF warned that "certain research and operations activities may be deferred until next year's austral research season." For scientists studying everything from ocean acidification to earthquakes to seal pups, the 16 days of the shutdown were 16 missed opportunities to collect irreplaceable data.

One of those scientists was Gretchen Hofmann, a marine biologist at the University of California, Santa Barbara, who published a column today in Nature about her frustration with the shutdown and its long-term impacts on basic research. As Hofmann and her peers stand by for word from NSF, we spoke to her about how some of the worst pain from the last two weeks could be felt by the next generation of up-and-coming scientists.

Climate Desk: What have the last couple weeks been like for you?

Gretchen Hofmann: We have a research project that's funded to study ocean conditions and ocean acidification in the Southern Ocean, the area around McMurdo Sound. That project was supposed to start October 10, and we were going to deploy one of our field team members down there to go retrieve sensors from under the sea ice. The government shut down and we just sat there and thought, 'Well, I guess she's not going,' and sure enough 24 hours before Lydia Kapsenberg, my grad student, was supposed to deploy, her travel was canceled. A week earlier, my post-doc Amanda Kelley, an NSF funded research fellow, was supposed to go down; she flew down there, landed on the sea ice, and literally was told that the station had gone into caretaker mode. So right away, right in my face, front row center, I had two junior scientists that were really heavily impacted by this. Not only because they stand to lose to data and progress in their careers; it was also really upsetting. I mean, they felt really threatened and jeopardized.

"The shutdown, with respect to Antarctic science, was as poorly timed as you could possibly manage."

CD: You make the point that while there are impacts for everyone working down there, it's especially a problem for young scientists, post-docs and grad students. Explain why. What's different about being in that position that makes a missed opportunity like this even more problematic?

GH: The reason that it's a sensitive life history stage is because, if we talk about Dr. Kelley, she's a post-doc, and that's kind of like being an apprentice electrician: You already have your license, in this case a PhD, and she now comes to work with me to really learn about how to be a scientist. During that time, these jobs are really competitive, and you need to be productive. By that I mean you need to do experiments, you need to publish papers, you need to go to science meetings and get out there. And with no data, with a canceled field season, she will not have that. And so that puts her back incredibly.

And grad students, well, forget about it. Many of them have planned to be at McMurdo to do a specific thing that will give them their PhD or their masters degree. And that's been completely canceled. It's even worse sometimes for grad students because if they know they're going to do something down there, they might spend the whole year training to do that; frankly, they're not doing anything else. They spent a whole bunch of time getting ready to be there, and when that gets canceled, then they've got nothin'. And so a year of their life could be delayed, they might have to stay in school for another year, their advisor might not have funding for them, so it throws them into a really difficult situation that can also involve financial problems. I worry about this every day. People send you their children, and our country depends on this new talent. And so it's kind of like we're eating our young in the Antarctic science community if we can't rescue the field season.

"We're eating our young in the Antarctic science community if we can't rescue the field season."

Amanda Kelley is an unfortunate example of this. She has a two-year fellowship from NSF that just started this summer. She was supposed to work at McMurdo for the field season this October/November, and October/November, 2014, and that's all the money she has for those two years. And so now, if she loses this field season, she'll run out of money before she can get a full set of research done. And everyone [at NSF] will do their utmost to rectify the situation, but whereas I stand to lose some data and an instrument and that's a drag and sets my research back, you know, I'm protected, I'm tenured. And these guys are not.

Supreme Court to Take Up Greenhouse Gas Limits

| Tue Oct. 15, 2013 1:12 PM PDT

The Supreme Court announced today that it will take up the question of whether the Environmental Protection Agency can include greenhouse gas emission limits in permits it issues for new or expanding large polluters like refineries and power plants.

But perhaps even more significant was what the court chose not to consider: a challenge to the EPA's broader authority to regulate greenhouse gases as dangerous pollutants under the Clean Air Act, and a challenge to its authority to issue emission limits for cars, both of which have been upheld by lower courts and remained untouched today.

For now, the justices chose to leave intact the legal basis for greenhouse gas emissions limits on new and existing power plants the EPA is expected to roll out over the next several years. Those limits could shutter many of the nation's coal plants and discourage others from opening. Today's announcement also preserves the Obama administration's plan to slash climate change-causing pollutants from cars.

The justices' decision "means that EPA's legal and scientific findings that greenhouse gases harm health and the climate remains the law of the land," said Natural Resources Defense Council senior attorney John Walke.

"The EPA's findings that greenhouse gases harm health and the climate remains the law of the land."

The question the court will consider is whether the EPA can use greenhouse gas emissions as a criteria, like it does with smog and soot limits, to determine whether large industrial polluters receive permits to build new facilities or expand existing ones. But even if the justices disallow such a permitting criteria, the EPA would still retain the authority to set greenhouse gas emissions limits for these polluters—just not written into the permits, per se.

The petition behind the permitting issue was brought by a coalition of industry groups, including the National Association of Manufacturers, which in a statement today said "stringent permitting requirements" would "impact every aspect of our economy."

But Walke stressed that the permitting program "is not necessary to establish or enforce" greenhouse gas emission standards for power plants, like those proposed in September that are a signature product of new EPA administrator Gina McCarthy.

WATCH: Drought-Hardy Barley Could Save Your Beer

| Mon Oct. 14, 2013 3:00 AM PDT

Raise a glass to these German scientists, who are working out a way to protect a key beer ingredient from climate change. As Oktoberfest rages on, geneticist Nils Stein is deciphering the genome of barley, looking for genes that could help the plant survive through droughts. The study's implications go beyond these beer tents. Barley is the fourth most produced cereal in the world; a recent drought in Russia that hurt barley production led to a global price spike. And a drought that devastated Syria's barley crop contributed to that country's civil war.
