7 climate change projects that are changing the game
While there's plenty to be worried about, it's important to remember that we're making progress, too.
- If we do nothing, global temperatures could rise as high as 10 degrees Celsius by the end of the century.
- Fortunately, humanity is hard at work at keeping temperature increases below the 2 degrees Celsius mark.
- These 7 projects are just a snapshot of what humanity is collectively doing to fight back and beat climate change.
It's easy to feel hopeless when it comes to the climate. The news is full of stories on how the next century will see unbearable heat waves, impossibly strong hurricanes, flooded cities, an ice-free Arctic, and global temperatures reaching up to an average of 10 degrees Celsius hotter than they already are. But despite how terrible this feels, it's important to remember that the appropriate response is to leap into action, not to be paralyzed by despair. To supply some optimism and show that humanity isn't totally screwed, here are 7 climate change projects that are changing the game.
1. Carbon Engineering Ltd's negative-emissions plant
One of the biggest challenges to combatting climate change is the lack of incentive (aside from the destruction of the planet, that is). When looking at the astronomical profits of the oil and gas industries, it's clear that reducing humanity's reliance on oil and gas will take some serious incentivization.
That's where Carbon Engineering comes in. The Canadian company intends to build a commercial-scale negative-emissions facility using funding from a variety of investors, including Bill Gates. These people didn't invest entirely out of the goodness of their hearts; they did so to make a profit.
The facility will suck CO2 out of the atmosphere to either store it underground, where it can't affect the atmosphere anymore, or to convert it into carbon-neutral fuel. What's more, this will happen at a rate of $100 per ton of CO2, the benchmark at which negative-emissions technology is considered to be cost effective.
2. Disney's new solar facility
As one of the largest entertainment corporations in the world, Disney has set itself an impressive goal: It intends to half its emissions by 2020. When you're talking about the emissions produced by a corporation worth $171.7 billion, that's pretty significant.
As an initial step towards this goal, Disney recently opened a 270-acre, 50-megawatt solar facility in Florida. Disney expects that this plant will produce enough energy to operate two of its four theme parks in central Florida and cut its greenhouse gas emissions by 57,000 tons per year. As an industry leader, their solar plant is likely a harbinger of more facilities across the United States — and world, for that matter.
3. Harvard's SCoPEx project: Dimming the sun
Short for the Stratospheric Controlled Perturbation Experiment, SCoPEx's controversial goal is to spray calcium carbonate — the same stuff in your antacid tablets — into the sky to observe its effects in the stratosphere, with the ultimate goal of observing whether it can reflect sunlight back into space.
This might seem familiar for those of you who have watched the movie Snowpiercer. In that film, the fictional chemical CW-7 is sprayed into the atmosphere to reverse climate change, ultimately cooling the planet too much and sending it into an apocalyptic Ice Age.
Fortunately, the Harvard researchers don't plan on coating the planet in calcium carbonate — since this is real life, and not a film, they'll perform controlled experiments using just a few hundred grams of the material. There are still concerns about what effects there could be, however; for one, even if a large-scale deployment of calcium carbonate would effectively reflect sunlight and cool the planet, it would still be a temporary solution.
Still, plants would also receive less sunlight and since calcium carbonate just isn't present in the stratosphere, nobody can really predict what side effects it might cause up there. Nevertheless, it's a valuable experiment that may show us a promising — albeit last-ditch — solution.
4. The spread of electric cars
In the U.S., transportation accounts for 28 percent of the country's greenhouse gas emissions. But not only do most major car companies now offer electric vehicles as part of their product lines, Tesla and other companies are focusing solely on producing electric cars. In February of 2019, Amazon invested $700 million in a Tesla competitor called Rivian, which plans to commercially release electric pick-up trucks in 2020. Tesla, too, is planning a release for 2020: a fully electric semitractor trailer.
These developments mean that the non-electric sectors of the transportation market are disappearing. Of course, none of this matters if there isn't the infrastructure there to support these cars. Fortunately, companies such as ChargePoint are installing charging stations across the country. As of this writing, ChargePoint has installed a little over 62,000 charging stations located across the globe.
5. The Environmental Business Initiative
It's rare that a big bank does anything as a force for good, but that's what Bank of America is doing with its Environmental Business Initiative. Part of what has made climate change projects so difficult to get going is the anxiety they produce in investors. This makes sense; a lot of climate change projects are new and use technologies not yet tested at large scales, risk factors that scare investment away. What's more, it's not always clear how an investor will make their money back.
Fortunately, Bank of America has invested $96 billion to date in a variety of sustainable businesses and promises to invest another $125 billion. The bank essentially invented the concept of green bonds, a type of security specifically reserved for climate and environmental projects.
6. The Green New Deal and growing political understanding
Addressing such a widespread and multifaceted threat like climate change will require a commensurately widespread and multifaceted climate policy. Although the Green New Deal was rejected in the U.S. Senate in March 2019, the mere fact that it existed at all is cause for optimism.
The future of climate change policy may not exactly match the ambitious Green New Deal, which aimed to make the U.S. energy system 100% renewable, to revamp the electrical grid into a "smart" grid, and overhaul the transportation system, among other goals. But it will certainly resemble it. Polls show that just 14.7 percent of Americans disagreed with the Green New Deal as a whole, a level of support that many politicians are responding to.
7. The promise of nuclear fusion
Tokamak Energy's fusion reactor
Nuclear power has always been a hot-button topic for environmentalists, and it was notably left out of the Green New Deal plan. If done right, nuclear fission plants can provide sustainable energy with minimal waste, but the problem is that they are not typically done right. Fission plants are expensive, complicated, and the repercussions of building a faulty one or failing to follow protocol are severe. Although the waste they do produce doesn't contribute to climate change, they are extremely toxic, must be carefully handled and stored, and can remain toxic for several thousands of years.
Nuclear fusion, on the other hand, doesn't carry the risk of a meltdown, produces waste whose radioactivity is short-lived, and it has the potential to produce unbelievable amounts of energy. Although fusion remains a hypothetical source of energy, we're getting closer and closer every year.
One nuclear fusion company, Tokamak Energy, recently heated hydrogen to 15 million degrees Celsius, briefly producing hydrogen plasma in a significant milestone on the way to fusion energy. Specifically, Tokamak Energy intends to heat hydrogen plasma to 100 million degrees Celsius in order to produce fusion energy. If its future ventures are successful, Tokamak Energy intends to deploy the world's first commercial nuclear fusion reactor by 2030. And they're not alone. Fusion experiments are taking place in countries such as France, Germany, and China, all of which have been making significant progress.
No one project will be the answer to the Earth's climate problems. But when taken together, they form a picture of the future that isn't quite so grim as we might believe today.

Richard Feynman once asked a silly question. Two MIT students just answered it.
Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.
But science loves a good challenge<p>The mystery remained unsolved until 2005, when French scientists <a href="http://www.lmm.jussieu.fr/~audoly/" target="_blank">Basile Audoly</a> and <a href="http://www.lmm.jussieu.fr/~neukirch/" target="_blank">Sebastien Neukirch </a>won an <a href="https://www.improbable.com/ig/" target="_blank">Ig Nobel Prize</a>, an award given to scientists for real work which is of a less serious nature than the discoveries that win Nobel prizes, for finally determining why this happens. <a href="http://www.lmm.jussieu.fr/spaghetti/audoly_neukirch_fragmentation.pdf" target="_blank">Their paper describing the effect is wonderfully funny to read</a>, as it takes such a banal issue so seriously. </p><p>They demonstrated that when a rod is bent past a certain point, such as when spaghetti is snapped in half by bending it at the ends, a "snapback effect" is created. This causes energy to reverberate from the initial break to other parts of the rod, often leading to a second break elsewhere.</p><p>While this settled the issue of <em>why </em>spaghetti noodles break into three or more pieces, it didn't establish if they always had to break this way. The question of if the snapback could be regulated remained unsettled.</p>
Physicists, being themselves, immediately wanted to try and break pasta into two pieces using this info<p><a href="https://roheiss.wordpress.com/fun/" target="_blank">Ronald Heisser</a> and <a href="https://math.mit.edu/directory/profile.php?pid=1787" target="_blank">Vishal Patil</a>, two graduate students currently at Cornell and MIT respectively, read about Feynman's night of noodle snapping in class and were inspired to try and find what could be done to make sure the pasta always broke in two.</p><p><a href="http://news.mit.edu/2018/mit-mathematicians-solve-age-old-spaghetti-mystery-0813" target="_blank">By placing the noodles in a special machine</a> built for the task and recording the bending with a high-powered camera, the young scientists were able to observe in extreme detail exactly what each change in their snapping method did to the pasta.

What possible application could this have?<p>The snapback effect is not limited to uncooked pasta noodles and can be applied to rods of all sorts. The discovery of how to cleanly break them in two could be applied to future engineering projects.</p><p>Likewise, knowing how things fragment and fail is always handy to know when you're trying to build things. Carbon Nanotubes, <a href="https://bigthink.com/ideafeed/carbon-nanotube-space-elevator" target="_self">super strong cylinders often hailed as the building material of the future</a>, are also rods which can be better understood thanks to this odd experiment.</p><p>Sometimes big discoveries can be inspired by silly questions. If it hadn't been for Richard Feynman bending noodles seventy years ago, we wouldn't know what we know now about how energy is dispersed through rods and how to control their fracturing. While not all silly questions will lead to such a significant discovery, they can all help us learn.</p>
The multifaceted cerebellum is large — it's just tightly folded.
- A powerful MRI combined with modeling software results in a totally new view of the human cerebellum.
- The so-called 'little brain' is nearly 80% the size of the cerebral cortex when it's unfolded.
- This part of the brain is associated with a lot of things, and a new virtual map is suitably chaotic and complex.
Just under our brain's cortex and close to our brain stem sits the cerebellum, also known as the "little brain." It's an organ many animals have, and we're still learning what it does in humans. It's long been thought to be involved in sensory input and motor control, but recent studies suggests it also plays a role in a lot of other things, including emotion, thought, and pain. After all, about half of the brain's neurons reside there. But it's so small. Except it's not, according to a new study from San Diego State University (SDSU) published in PNAS (Proceedings of the National Academy of Sciences).
A neural crêpe
A new imaging study led by psychology professor and cognitive neuroscientist Martin Sereno of the SDSU MRI Imaging Center reveals that the cerebellum is actually an intricately folded organ that has a surface area equal in size to 78 percent of the cerebral cortex. Sereno, a pioneer in MRI brain imaging, collaborated with other experts from the U.K., Canada, and the Netherlands.
So what does it look like? Unfolded, the cerebellum is reminiscent of a crêpe, according to Sereno, about four inches wide and three feet long.
The team didn't physically unfold a cerebellum in their research. Instead, they worked with brain scans from a 9.4 Tesla MRI machine, and virtually unfolded and mapped the organ. Custom software was developed for the project, based on the open-source FreeSurfer app developed by Sereno and others. Their model allowed the scientists to unpack the virtual cerebellum down to each individual fold, or "folia."

A complicated map
Sereno tells SDSU NewsCenter that "Until now we only had crude models of what it looked like. We now have a complete map or surface representation of the cerebellum, much like cities, counties, and states."
That map is a bit surprising, too, in that regions associated with different functions are scattered across the organ in peculiar ways, unlike the cortex where it's all pretty orderly. "You get a little chunk of the lip, next to a chunk of the shoulder or face, like jumbled puzzle pieces," says Sereno. This may have to do with the fact that when the cerebellum is folded, its elements line up differently than they do when the organ is unfolded.
It seems the folded structure of the cerebellum is a configuration that facilitates access to information coming from places all over the body. Sereno says, "Now that we have the first high resolution base map of the human cerebellum, there are many possibilities for researchers to start filling in what is certain to be a complex quilt of inputs, from many different parts of the cerebral cortex in more detail than ever before."
This makes sense if the cerebellum is involved in highly complex, advanced cognitive functions, such as handling language or performing abstract reasoning as scientists suspect. "When you think of the cognition required to write a scientific paper or explain a concept," says Sereno, "you have to pull in information from many different sources. And that's just how the cerebellum is set up."
Bigger and bigger
The study also suggests that the large size of their virtual human cerebellum is likely to be related to the sheer number of tasks with which the organ is involved in the complex human brain. The macaque cerebellum that the team analyzed, for example, amounts to just 30 percent the size of the animal's cortex.
"The fact that [the cerebellum] has such a large surface area speaks to the evolution of distinctively human behaviors and cognition," says Sereno. "It has expanded so much that the folding patterns are very complex."
As the study says, "Rather than coordinating sensory signals to execute expert physical movements, parts of the cerebellum may have been extended in humans to help coordinate fictive 'conceptual movements,' such as rapidly mentally rearranging a movement plan — or, in the fullness of time, perhaps even a mathematical equation."
Sereno concludes, "The 'little brain' is quite the jack of all trades. Mapping the cerebellum will be an interesting new frontier for the next decade."
What happens if we consider welfare programs as investments?
- A recently published study suggests that some welfare programs more than pay for themselves.
- It is one of the first major reviews of welfare programs to measure so many by a single metric.
- The findings will likely inform future welfare reform and encourage debate on how to grade success.
Welfare as an investment<p>The <a href="https://scholar.harvard.edu/files/hendren/files/welfare_vnber.pdf" target="_blank">study</a>, carried out by Nathaniel Hendren and Ben Sprung-Keyser of Harvard University, reviews 133 welfare programs through a single lens. The authors measured these programs' "Marginal Value of Public Funds" (MVPF), which is defined as the ratio of the recipients' willingness to pay for a program over its cost.</p><p>A program with an MVPF of one provides precisely as much in net benefits as it costs to deliver those benefits. For an illustration, imagine a program that hands someone a dollar. If getting that dollar doesn't alter their behavior, then the MVPF of that program is one. If it discourages them from working, then the program's cost goes up, as the program causes government tax revenues to fall in addition to costing money upfront. The MVPF goes below one in this case. <br> <br> Lastly, it is possible that getting the dollar causes the recipient to further their education and get a job that pays more taxes in the future, lowering the cost of the program in the long run and raising the MVPF. The value ratio can even hit infinity when a program fully "pays for itself."</p><p> While these are only a few examples, many others exist, and they do work to show you that a high MVPF means that a program "pays for itself," a value of one indicates a program "breaks even," and a value below one shows a program costs more money than the direct cost of the benefits would suggest.</p> After determining the programs' costs using existing literature and the willingness to pay through statistical analysis, 133 programs focusing on social insurance, education and job training, tax and cash transfers, and in-kind transfers were analyzed. The results show that some programs turn a "profit" for the government, mainly when they are focused on children:
This figure shows the MVPF for a variety of polices alongside the typical age of the beneficiaries. Clearly, programs targeted at children have a higher payoff.
Nathaniel Hendren and Ben Sprung-Keyser<p>Programs like child health services and K-12 education spending have infinite MVPF values. The authors argue this is because the programs allow children to live healthier, more productive lives and earn more money, which enables them to pay more taxes later. Programs like the preschool initiatives examined don't manage to do this as well and have a lower "profit" rate despite having decent MVPF ratios.</p><p>On the other hand, things like tuition deductions for older adults don't make back the money they cost. This is likely for several reasons, not the least of which is that there is less time for the benefactor to pay the government back in taxes. Disability insurance was likewise "unprofitable," as those collecting it have a reduced need to work and pay less back in taxes. </p>
