Tim McDonnell joined Climate Desk after stints at Mother Jones and Sierra magazine. He remains a cheerful guy despite covering climate change all the time. Originally from Tucson, Tim loves tortillas and epic walks.
The US Navy base in Norfolk, Va., is a key piece of military infrastructure threatened by climate change.
President Barack Obama listed climate change alongside international terrorism, weapons of mass destruction, and infectious disease in a new national security strategy plan released today. The plan called climate change "an urgent and growing threat to our national security" and also called for the United States to diversify its energy sources to insulate the country from disruptions to foreign fossil fuel markets.
This isn't the first time the Obama administration has singled out climate as a major national security risk: A Pentagon report in October said global warming has become a short-term priority for strategic military planning. But the issue gets much more airtime in today's strategy than it did in the administration's first, issued back in 2010, where it merited just a few passing references. Overall, the document is in line with the more aggressive climate message that has emerged this year from the White House. You can read it below:
This morning Bloomberg New Energy Finance released a fat report on the state of US energy, and it's chock-full of kickass facts and figures that reveal real, tangible progress on reversing the habits that cause climate change. Here are just a few of the most salient bits:
The US is getting way more efficient. It used to be that electricity demand rose and fell roughly in line with economic productivity. That's no longer the case: Thanks to massive gains in energy efficiency in everything from home appliances to factory lines, energy demand is now less tied to economic growth than ever before. In fact, since 2007, electricity demand hasn't grown at all, the report finds. Zero. Another way to say that is that the US is becoming more "energy productive," meaning the US is using fewer units of energy for every unit of GDP. Energy productivity has increased 54 percent since 1990:
Since energy makes up about 83 percent of America's total carbon footprint, those gains in efficiency (along with big shakeups in where our energy comes from, which I'll get to shortly) have helped drive total carbon emissions down 9.2 percent from their 2007 all-time peak:
Coal is getting the boot. Coal used to provide half or more of the country's electricity. Now, that number is down to 39 percent, thanks largely to increasing reliance on natural gas made plentiful and cheap by the fracking boom. Both production and consumption of natural gas were at all-time highs in 2014:
Renewable energy is blowing up. Natural gas isn't the only big winner: Renewables are skyrocketing too. Solar and wind production have more than tripled since 2008. The share of all renewable energy sources combined (including large hydropower dams) in the US energy mix has nearly doubled since 2008, from 8 percent to 13 percent. This chart shows how much new capacity of each energy source was added in each year; the grey is natural gas and the light blue is renewables:
As we've reported before, solar is going gangbusters; the bars below show how much rooftop solar was added each year, and the red line represents the cumulative total:
Behind that trend is an ongoing freefall in the cost of solar panels. This chart shows how the more solar that gets installed, the cheaper each unit of it becomes, thanks to technology improvements and breakneck production at Chinese factories. The two lines are for different types of modules, but the important thing is that they're both headed downhill:
Cars are cleaner, and we're using them less. Gasoline consumption is down 8.6 percent from 2005, which the report attributes to "increasing vehicle efficiency prompted by federal policy, increasing consumer preference for less thirsty vehicles, changing driving patterns (declining number of vehicles on the road, declining miles per vehicle), and increasing biofuel blending." The relative climate benefits of biofuels are still being hotly debated, but the rest of those trends are pretty objectively awesome. The trend for electric vehicles is less impressive. Although the number of public electric vehicle charging stations has exploded 470 percent since 2011, sales are pretty ho-hum. The report blames low oil prices:
Earlier today the Environmental Protection Agency released a letter that one of its top officials sent yesterday to the State Department, weighing in on the debate over the Keystone XL pipeline. The letter is part of a last round of comments from federal agencies before the Obama administration makes a final decision about whether to approve the pipeline, and environmentalists had hoped that it would spell out the threat the project could pose to the climate.
They weren't disappointed. The EPA letter argues that the recent drop in oil prices means that Keystone XL could come with a major carbon footprint. This is an argument environmentalists like Bill McKibben have been pushing for years. And it's a big deal—President Barack Obama has said that the pipeline will be approved only if it won't increase overall greenhouse gas emissions.
Here's the logic: A pipeline is the cheapest way to move oil; trucks and trains are much more expensive. Canadian tar sands oil is especially expensive to produce. When the price of oil is high, it makes economic sense to export it with trucks and trains. This is the line of reasoning the State Dept. has used to argue that approving the pipeline won't contribute to climate change: The oil is going to get burned with or without Keystone XL, because producers will just send it out some other way. Republicans in Congress have cited that same State Dept. analysis as evidence that Keystone XL isn't the climate-killing monster environmentalists make it out to be.
But when the price of oil is so low, that calculus gets turned upside down. According to State's own analysis, the economic rationale for using trucks and trains starts to erode once the price of oil dips much below $75 per barrel. Right now, oil is hovering around $50 a barrel. So if prices stay low and the if the pipeline isn't built, that oil might actually stay buried—where many climate scientists have said it needs to stay if we're to avoid disastrous levels of global warming.
You can read the full EPA letter below. Here's the key line:
"At sustained oil prices within this range, construction of the pipeline is projected to change the economics of oil sands development and result in increased oil sands production, and the accompanying greenhouse gas emissions, over what would otherwise occur."
Some energy analysts disagree, arguing that oil prices would have to drop much further than current levels to have an impact on tar sands production. And even though there's reason to think oil could be cheap for a while, energy companies don't tend to make big expensive decisions about where and how to drill based on short-term market trends. So there's still room for debate on the EPA's take here.
The EPA letter is likely to become a centerpiece of the pipeline debate as Congress continues to wrangle over the issue. (A bill to approve the pipeline passed the Senate last week, and next week the House is expected to take it up once again. President Obama has promised to veto the bill.) But the more important thing to watch is whether it changes any minds in the Obama administration, which is nearing a final decision on whether the pipeline will be built.
Jeremy the koala in rehab after burning his paws. He was released back to the wild today.
After a series of devastating bushfires ripped through Australia earlier this month, volunteers across the world quickly came to the rescue with custom-knitted mittens for the burned paws of koalas (way too many volunteers, it turns out). The poster koala that sparked the movement was Jeremy, whose heart-rending hospital room portrait quickly went viral.
Good news! Jeremy is fully recovered and back in the wild. From the BBC:
He has since made a complete recovery, says Aaron Machado, who operates the clinic that treated the animal... "The only thing he has to do now is get used to not having any more room service," Mr Machado told the BBC.
At Ibrahim Mohammed's fish stall, business is slow.
He's sitting behind a wooden table piled with a dozen tilapia and Nile perch at the market in Katoro, a roadside town in northern Tanzania. The fish—a staple of the Tanzanian diet—came in that morning from Lake Victoria, an hour's drive north. Around us, hundreds of shoppers are snatching up pineapples, textiles, and motorcycle parts. But Mohammed explains that basic economics is keeping customers away from his fish.
"There's less fish," he says. "So the price goes up, so customers can't afford to buy."
In the two years Mohammed has operated this stall, the retail price for both species has doubled. An average Nile perch has gone from roughly $2 to $4; tilapia from $4 to $8. That's far above the overall rate of inflation.
Nile perch makes up the majority of the catch. An invasive species that has dominated the lake for half a century, it's driven many of the native fish to extinction, earning it a reputation as an ecological disaster. For fishermen, though, it has become a cornerstone of the economy.
Overfishing and climate change, O'Reilly says, are "the perfect storm."
But over the last several years, locals here say, fish yields have begun to drop. The culprit: a worrisome combination of overfishing and climate change.
Hard statistics are notoriously difficult to come by, as the resource-strapped federal fisheries agency struggles to keep tabs on an industry composed almost entirely of small-scale, informal operators. But a 2013 government audit painted a disturbing picture. Between 2009 and 2011, according to the audit, yields of Nile perch on Lake Victoria fell about 5 percent.
