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>

Well control equipment: Metal hat, Fireproof coveralls… CFD
By Gaetan Bouzard – In the Oil & Gas industry, the integration of possible risk linked with well control — such as subsea plume, atmospheric dispersion, fire and explosion — is critical for minimizing impact on the entire system or on operations efficiency, and for ensuring worker health and safety. Risk to system integrity must be prevented at the design phase, but also addressed in case hazards happen along equipment lifetime or system in operation.
Last September 25th, Mr. Alistair E. Gill, from company Wild Well Control demonstrates the value of advanced structural and fluid dynamics mechanics simulation for well controls, emergency response and planning, as part of a Live Webinar organized by Siemens and Society of Petroleum Engineers. In this article I will try to summarize his presentation. To have more insights feel free to watch our On-Demand Webinar.
To be honest when talking about well control for Oil & Gas industry, people usual conception is that some disaster happened and guys wearing protections are trying to light off a big fire. Actually companies such as Wild Well Control are using modern and innovative techniques as Computational Fluid Dynamics (CFD) simulation to support practical team on a well control incident trying to keep asset integrity at the same time.
Mr. Gill provides several examples to demonstrate simulation techniques that were used from
- Subsea plume and gas dispersion modeling to understand where hydrocarbons go in the event of a blow out
- Radiant heat modeling in case of a fire
- Erosion modeling
- Thermal as well as Structural analysis
There is basically three major categories of simulation used, starting with everything related to the flow within the well bore, looking at kick tolerance, dynamic kill or bull heading; next anything to do with 3D flow using CFD simulation which is the main focus of this article; finally structural analysis using Finite Element modeling. more>

Signals from Distant Lightning Could Help Secure Electric Substations
By John Toon – Side channel signals and bolts of lightning from distant storms could one day help prevent hackers from sabotaging electric power substations and other critical infrastructure, a new study suggests.
By analyzing electromagnetic signals emitted by substation components using an independent monitoring system, security personnel could tell if switches and transformers were being tampered with in remote equipment. Background lightning signals from thousands of miles away would authenticate those signals, preventing malicious actors from injecting fake monitoring information into the system.
The research, done by engineers at the Georgia Institute of Technology, has been tested at substations with two different electric utilities, and by extensive modeling and simulation. Known as radio frequency-based distributed intrusion detection system (RFDIDS), the technique was described February 26 at the 2019 Network and Distributed System Security Symposium (NDSS) in San Diego.
“We should be able to remotely detect any attack that is modifying the magnetic field around substation components,” said Raheem Beyah, Motorola Foundation Professor in Georgia Tech’s School of Electrical and Computer Engineering and co-founder of Fortiphyd Logic, Inc. “We are using a physical phenomenon to determine whether a certain action at a substation has occurred or not.”
Opening substation breakers to cause a blackout is one potential power grid attack, and in December 2015, that technique was used to shut off power to 230,000 persons in the Ukraine. Attackers opened breakers in 30 substations and hacked into monitoring systems to convince power grid operators that the grid was operating normally. Topping that off, they also attacked call centers to prevent customers from telling operators what was happening. more>
