No institution or individual can stand on the sidelines in the fight against climate change
By Kristalina Georgieva – When I think of the incredible challenges we must confront in the face of a changing climate, my mind focuses on young people. Eventually, they will be the ones either to enjoy the fruits or bear the burdens resulting from actions taken today.
Our efforts to reduce greenhouse gas emissions through various mitigation measures—phasing out fossil fuels, increasing energy efficiency, adopting renewable energy sources, improving land use and agricultural practices—continue to move forward, but the pace is too slow. We have to scale up and accelerate the transition to a low-carbon economy. At the same time, we must recognize that climate change is already happening and affecting the lives of millions of people. There are more frequent and more severe weather-related events—more droughts, more floods, more heat waves, more storms.
Ready or not, we are entering an age of adaptation. And we need to be smart about it. Adaptation is not a defeat, but rather a defense against what is already happening. The right investments will deliver a “triple dividend” by averting future losses, spurring economic gains through innovation, and delivering social and environmental benefits to everyone, but particularly to those currently affected and most at risk. Updated building codes can ensure infrastructure and buildings are better able to withstand extreme events. Making agriculture more climate resilient means investing more money in research and development, which in turn opens the door to innovation, growth, and healthier communities.
The IMF is stepping up its efforts to deal with climate risk. Our mission is to help our members build stronger economies and improve people’s lives through sound monetary, fiscal, and structural policies. more>

A strategy to protect whales can limit greenhouse gases and global warming
By Ralph Chami, Thomas Cosimano, Connel Fullenkamp, and Sena Oztosun – When it comes to saving the planet, one whale is worth thousands of trees.
Scientific research now indicates more clearly than ever that our carbon footprint—the release of carbon dioxide (CO2) into the atmosphere where it contributes to global warming through the so-called greenhouse effect—now threatens our ecosystems and our way of life. But efforts to mitigate climate change face two significant challenges. The first is to find effective ways to reduce the amount of CO2 in the atmosphere or its impact on average global temperature. The second is to raise sufficient funds to put these technologies into practice.
Many proposed solutions to global warming, such as capturing carbon directly from the air and burying it deep in the earth, are complex, untested, and expensive. What if there were a low-tech solution to this problem that not only is effective and economical, but also has a successful funding model?
An example of such an opportunity comes from a surprisingly simple and essentially “no-tech” strategy to capture more carbon from the atmosphere: increase global whale populations. Marine biologists have recently discovered that whales—especially the great whales—play a significant role in capturing carbon from the atmosphere (Roman and others 2014).
The carbon capture potential of whales is truly startling. Whales accumulate carbon in their bodies during their long lives. When they die, they sink to the bottom of the ocean; each great whale sequesters 33 tons of CO2 on average, taking that carbon out of the atmosphere for centuries. A tree, meanwhile, absorbs only up to 48 pounds of CO2 a year.
Protecting whales could add significantly to carbon capture because the current population of the largest great whales is only a small fraction of what it once was. Sadly, after decades of industrialized whaling, biologists estimate that overall whale populations are now to less than one fourth what they once were. Some species, like the blue whales, have been reduced to only 3 percent of their previous abundance. Thus, the benefits from whales’ ecosystem services to us and to our survival are much less than they could be.
But this is only the beginning of the story. more>

By Tom Nichols – I’m used to people disagreeing with me on lots of things. Principled, informed arguments are a sign of intellectual health and vitality in a democracy. I’m worried because we no longer have those kinds of arguments, just angry shouting matches.
I fear we are moving beyond a natural skepticism regarding expert claims to the death of the ideal of expertise itself: a Google-fueled, Wikipedia-based, blog-sodden collapse of any division between professionals and laypeople, teachers and students, knowers and wonderers—in other words, between those with achievement in an area and those with none. By the death of expertise, I do not mean the death of actual expert abilities, the knowledge of specific things that sets some people apart from others in various areas.
There will always be doctors and lawyers and engineers and other specialists. And most sane people go straight to them if they break a bone or get arrested or need to build a bridge. But that represents a kind of reliance on experts as technicians, the use of established knowledge as an off-the-shelf convenience as desired. “Stitch this cut in my leg, but don’t lecture me about my diet.”
The larger discussions, from what constitutes a nutritious diet to what actions will best further U.S. interests, require conversations between ordinary citizens and experts. But increasingly, citizens don’t want to have those conversations. Rather, they want to weigh in and have their opinions treated with deep respect and their preferences honored not on the strength of their arguments or on the evidence they present but based on their feelings, emotions, and whatever stray information they may have picked up here or there along the way.
This is a very bad thing. more>

Tiny Vibration-Powered Robots Are the Size of the World’s Smallest Ant
By John Toon – Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
The prototype robots respond to different vibration frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long – about the size of the world’s smallest ant – the bots can cover four times their own length in a second despite the physical limitations of their small size.
“We are working to make the technology robust, and we have a lot of potential applications in mind,” said Azadeh Ansari, an assistant professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. “We are working at the intersection of mechanics, electronics, biology and physics. It’s a very rich area and there’s a lot of room for multidisciplinary concepts.”
A paper describing the micro-bristle-bots has been accepted for publication in the Journal of Micromechanics and Microengineering. The research was supported by a seed grant from Georgia Tech’s Institute for Electronics and Nanotechnology. In addition to Ansari, the research team includes George W. Woodruff School of Mechanical Engineering Associate Professor Jun Ueda and graduate students DeaGyu Kim and Zhijian (Chris) Hao. more>

Digitalize battery manufacturing for a greener future with electric vehicles
By Vincent Guo – The electrification of automobiles is gaining momentum globally as many countries have laid out plans to prohibit the sales of internal combustion engine (ICE) cars. The closing deadline is 2025 for the Netherlands and Norway, with Germany and India to be the next down the line in 2030, followed by UK and France in 2040. Other major economies in the world provide aggressive initiatives to push the electric vehicle (EV) to the market. For example, USA, China, Norway, Denmark, and South Korea have been implementing cash subsidiaries to EV buyers over $10,000 per vehicle, with Denmark and South Korea paying the consumer almost 20,000 Euro for each car purchased.
These incentive plans, however, also indicate that the price of EV is still high comparing to traditional cars. Independent research shows that the cost of the electrical powertrain is roughly 50% of the EV while, while the cost of the powertrain for ICE cars is only 16%. While it is largely true that the components of a car, whether it is an EV or ICE car, are largely similar except for the powertrain, the source of the difference in total cost is obviously the powertrain. The most expensive component is the battery pack, which accounts for roughly half of the powertrain and a quarter of the entire car.
Fortunately, the cost of the battery is going down steadily in the past 10 years. It is about to hit the point that the total cost of an EV is competitive to an ICE car and the point is about 125-150 USD/kWh.
As a result, battery manufacturing capacity has been ramping up quickly. Tesla is leading the way by its Gigafacotry in Nevada with target annual capacity of 35 GWh. Yet the race is tight as the battery manufacturing in Asia is catching up. CATL of China had recently announced a plan to boost its capacity in Germany to 100 GWh. more>
