Great post today by a top environmental economist on how government is needed to let marketplace solutions work out. In other words, even libertarian economic theory doesn't suggest that destroying the EPA is a good idea.
In other news, environmental monitoring has revealed that although carbon dioxide emissions are declining, methane is actually up. This is really bad: methane does much more damage than CO2 once it's out there. The question now is where all that methane is coming from: some say it might be from emissions related to fracking, while others blame increased agriculture and increased livestock production. Undoubtedly both matter, and the question is how to make things better. Here in the US a good place to start would be by being a little more careful in our fracking: using natural gas is supposed to be less environmentally damaging than coal, but if we don't capture all the emissions done when we frack for gas, we could end up making things worse.

Electric cars
The need to gird ourselves for a Battle Royale on the environmental front makes me want to hide anything that might possibly be used by the other side, but that's not a useful impulse. As an academic it's my job to continue to evaluate the evidence fairly, and as the Guardian points out today, there are some flaws with the existing infrastructure behind electric cars.
First, they will only be as environmentally friendly as their fuel. If coal is burned to produce energy used to run a Tesla, it might as well be driving on gas (well, almost). Elon Musk's long-term plan for his vehicles includes solar-powered charging for the vehicles, but other electric vehicles aren't taking any such steps.
Second, making batteries can be rather nasty for the environment, imposing an additional burden.
If you start off at a deficit and don't get yourself out, you don't end up ahead. We need to take care that electric cars don't end up in that position!

EPA
I don't have the stomach to write much about this- I am literally nauseous- but the choice to run the EPA is profoundly disturbing. With no background in science, no background in economics, Scott Pruitt has spent his career fighting medical care for the poor, undermining same-sex marriage, advocating for environmental damage, and of course most prominently declaiming against climate change, in spite of the work of thousands of scientists.
While our society needs energy, we must also take into account cleanliness and safety in thinking about how we get it. Air pollution kills. Fracking in Oklahoma has caused earthquakes, damaging homes and property, The potential damage of climate change includes droughts, heat waves, more intense hurricanes and other major storms, and rising sea levels, damaging agriculture, infrastructure, insect outbreaks, wildfires, loss of species, and human health impacts.
I'm just stunned that all of those concerns are going to be ignored. I guess the rich will be less affected by all of those things, so why worry?

and... steps backwards on climate
The next four years are going to be... something. Here's Trump's energy policy.
...
One faint bit of good news is that the prices of oil and coal are really low right now, limiting the attractiveness of newly opened lands to mining and drilling. Hopefully Elon Musk can keep driving down the cost of solar power and electric vehicles so there is even less interest in burning coal or drilling oil.
We are in for a bumpy ride.

Progress on Climate
You probably heard that the Paris Agreement has come into effect, and you may have heard that the 22nd Conference of the Parties (COP) is starting today. It seems like the world is taking steps- small steps, and much later than they should have been taken- but still, it's reason for optimism.
One particularly appealing prospect is that of saying "yes" to more forests rather than just "no" to coal, fossil-fuel powered vehicles, etc. This writer thinks that forest development should be the heart of any strategy against climate change. Obviously pro-forest policies are costly too- preventing someone from developing their land keeps them from becoming richer, and people living near restricted land might have a hard time, say, getting access to electric power. Clearly the goal is not to keep people in the dark ages!

Rebound effect: death prevention version
One reason energy-saving technologies don't always make as much a difference as expected is the "rebound effect" (WikiLink)- if something becomes easier/ cheaper/ safer, people will do more/ spend more/ take more risks. If cars use less gas, people may drive farther, since it has become cheaper to travel. People don't feel bad about eating a whole pack of cookies as long as they are "low-calorie" cookies.
The scariest version I've seen of this is right here. Since paramedics have really good medicine to help save people from overdoses, drug users may feel safer in shooting up, putting their lives at risk assuming that paramedics will reach them in time. Alternatively, drug users may mix narcotics with the life-saving substance to do "yo-yoing": shooting up to a high and bouncing back down as the other drug in the cocktail (hopefully) brings you back.
Scary stuff!

GMO's are worthless
That's what the NYT would have you believe. They compare US productivity against European productivity, noting that GMOs are rare in the EU but productivity levels are similar. (This is attributed to "European anger at the idea of fooling with nature.") They do note that no health concerns have been convincingly shown: GMOs are as healthy as any other crop variants.
Further, they contend that GMOs haven't curbed insecticide use, and they have increased herbicide use. The latter claim is almost certainly true: some GMO crops are designed to encourage use of herbicides. Why would anyone want to plant those crops? Well, every farmer has to deal with weeds, and think about how nice it would be to just spray chemicals that know to kill every plant except the good ones. That's what this GMO seed is: the plant isn't affected by the herbicide, so farmers can spray with impunity.
Leaving aside the question of what it means to "fool with nature" (for example, is a human artificially putting a seed into the ground "fooling with nature"? How about killing the bugs that eat the plants?), a few shortcomings of this analysis are apparent.
1) I think most advocates of GMOs would contend that GMOs improve "total factor productivity" whether or not they improve yields. In other words, you might not get more grain per acre of land, but you might get more grain per ton of fertilizer applied, or more grain per hour of human time invested. I don't have any numbers off the top of my head, but these are questions the article doesn't address.
2) Herbicide use is bad, but the alternative is watching your soil be carried down the river. While that sounds like a disaster for the environment, consider this: the other way that people fight weeds is by plowing the land, tearing plants up and driving parts of them underground. this has the effect of facilitating soil runoff. I'm as unhappy about chemicals being sprayed on the land as the next person, but I'm also unhappy when I see the Mississippi River Delta expanding every year because of all the soil carried down the river. Losing soil is a real problem, potentially threatening agriculture itself, and applying herbicides slows the rate of soil loss. (Also, saving soil prevents the release of carbon into the atmosphere, slowing climate change.)
3) Take a look at my former professor David Zilberman's ode to Monsanto, describing his very positive view of the company. His research has shown that skepticism of GMOs has cost the world hundreds of billions of dollars in value... as well as millions of people's eyesight lost due to short-sighted (yuk) resistance to Golden Rice, a genetically engineered product designed to get vitamin A to populations who normally don't get enough, and who often lose their eyesight because of it.
