There is no disputing that the world is facing an energy crisis of vast proportions. But this could have been avoided. For more than five decades, scientists, engineers, energy planners, policy makers, and, at times, even the public at large, have known what the ultimate alternative is to our finite energy resources–nuclear fusion. This energy, which powers the Sun and all of the stars, and can use a virtually unlimited supply of isotopes of hydrogen,available from sea water, has been visible on the horizon for years, but seemingly never close at hand. Why?
Legend has it that there are more problems in attaining controlled nuclear fusion than scientists anticipated, a nd that little progress has been made. “Fusion is still fifty years away, and always has been” has become the common refrain of skeptics. But the reason that we do not have commercially available fusion energy is not what is commonly believed.
A Cambridge University professor has been accused of “crying wolf” by predicting the imminent disappearance of Arctic ice.
Peter Wadhams has been criticised by scientists who fear that he could undermine the credibility of climate science by making doom-laden forecasts. He repeatedly predicted that the Arctic would be “ice-free” by last summer, by which he meant it would have less than one million sq km of ice. His forecasts, reported around the world, turned out to be wrong.
Russian officials announced a pair of major technological breakthroughs that will turn spent nuclear waste into fuel for reactors. If true, the new technology could change the world’s energy landscape in the next decade.
Testing has already begun on components needed to reprocess waste into fuel, as has the construction of reactors to use it. The first of the new reactors should be completed by 2025.
Russia’s new reactors are theoretically capable of eliminating the production of radioactive waste, achieving a “closed loop” of nuclear power generation where waste would fuel other reactors. The country currently operates 35 nuclear reactors, getting about 19 percent of its electricity from them. The country already planned to build 20 new reactors and sell many more to other countries, according to the World Nuclear Association. The new breakthrough caused the Russian government to announce plans to build another 11 reactors.
Paper Reviewed: Wang, J., Liu, X., Zhang, X., Smith, P., Li, L., Filley, T.R., Cheng, K., Shen, M., He, Y. and Pan, G. 2016. Size and variability of crop productivity both impacted by CO2 enrichment and warming – A case study of 4 year field experiment in a Chinese paddy. Agriculture, Ecosystems and Environment221: 40-49.
Providing the rationale for their study, Wang et al. (2016) write that few studies have focused on the interaction between atmospheric CO2 enrichment and warming on crop growth, such that the combined effects of these two important variables “are still not well understood.” In an effort to advance our understanding in this area, the ten-member research team conducted an experiment examining the effects of these two variables on two important food crops: wheat and rice.

Behavioral plasticity is the ability of a species to alter its behavior in response to changes in climate. It is an adaptive mechanism that allows species to persist in regions outside their normal climate envelope to which they are generally constrained and therefore represents a means by which they might persist in the face of ongoing climate change. However, behavioral plasticity is an understudied subject and there is much that remains to be learned about this topic.
Finally, expert climate modelers are “surprised” to discover this:
“…their study had detected warming in the Arctic and tropical oceans from around the 1830s, just 80 years after the Industrial Revolution started in England. “It was an extraordinary finding,” she said. “It was one of those moments where science really surprised us. But the results were clear. The climate warming we are witnessing today started about 180 years ago.”
How many grant dollars did it take to figure out what skeptical scientists have been saying for years?

It’s not very often we get to talk about a revolution in understanding and treating depression and yet now doctors are talking about “one of the strongest discoveries in psychiatry for the last 20 years”.
It is based around the idea that some people are being betrayed by their fiercest protector. That their immune system is altering their brain. The illness exacts a heavy toll on 350 million people around the world, among them Hayley Mason, from Cambridgeshire:
“My depression gets so bad that I can’t leave the bed, I can’t leave the bedroom, I can’t go downstairs and be with my partner and his kids.

In this intriguing new study, Viterito (2016) shows that increasing seismic activity of the globe’s high geothermal flux areas (HGFAs) — which is indicative of increasing geothermal forcing — is “highly correlated with average global temperatures from 1979 to 2015,” while “the correlation between carbon dioxide loading and global temperatures for the same period is lower.” And he thus notes that “HGFA seismicity is a significant predictor of global temperatures.”
Dr. Roger Pielke Jr. has a message for anyone linking #Climate Change with the Louisiana floods: it’s irresponsible and not based on #Science. He even produced multiple graphs showing a downward trend for these heavy precipitation events.
A professor in the Environmental Studies Program at the University of Colorado, Pielke has been at the forefront of the global warming debate for over a decade. As a climate expert, he’s even testified before Congress on extreme weather events and written a book on disasters and climate change.
Russia has reached two more milestones in its endeavour to close the nuclear fuel cycle. Mashinostroitelny Zavod (MSZ) – part of Russian nuclear fuel manufacturer TVEL – has completed acceptance tests of components for its ETVS-14 and ETVS-15 experimental fuel assemblies with mixed nitride fuel for the BREST and BN fast neutron reactors. MSZ has also announced the start of research and development work on the technical design of the “absorbent element” of the core of the BREST-OD-300 reactor.

NASA is reconsidering whether tank foam debris caused the Columbia disaster. That’s quite a shift from days earlier when the foam was the “leading candidate” — an explanation that quickly became embarrassing.
We may never know precisely what happened to Columbia, but one thing should be clear — NASA should not be in charge of investigating itself.
A chunk of foam insulation broke off the external fuel tank during launch, perhaps damaging Columbia’s heat-protecting tiles. “We’re making the assumption that the external tank was the root cause of the accident,” said shuttle program manager Ron Dittemore in the immediate aftermath.
Modern science rests upon “a bald-faced but beautiful lie” from which it draws its “political and cultural power.” That is how Dan Sarewitz describes the myth that underpins modern science.
That lie holds that scientists following their curiosity, motivated by little else and certainly not political considerations, advance understandings and thus our ability to make wise decisions. THB is also an effort to critique this “beautiful lie.”
A key element in that lie is that scientists are neutral arbiters of truth, who sit above the rough and tumble of political debates. Like philosopher kings, their neutrality should be used to arbitrate our difficult debates. Sounds great. Most myths do.
Science, pride of modernity, our one source of objective knowledge, is in deep trouble. Stoked by fifty years of growing public investments, scientists are more productive than ever, pouring out millions of articles in thousands of journals covering an ever-expanding array of fields and phenomena. But much of this supposed knowledge is turning out to be contestable, unreliable, unusable, or flat-out wrong. From metastatic cancer to climate change to growth economics to dietary standards, science that is supposed to yield clarity and solutions is in many instances leading instead to contradiction, controversy, and confusion. Along the way it is also undermining the four-hundred-year-old idea that wise human action can be built on a foundation of independently verifiable truths. Science is trapped in a self-destructive vortex; to escape, it will have to abdicate its protected political status and embrace both its limits and its accountability to the rest of society.
From climate doomsters to media politicos, the world is being bombarded with mis-constructs, unfounded claims and outright lies. Some listeners and readers may fall for such deceits but many others are thinking to themselves and quietly walking away.
Time and again, I have experienced that phenomenon after giving a talk to (mostly) retired professionals from a variety of disciplines. They approach me in private with statements like “fully agree with you but am afraid to speak out.” Too few speak up in public – though they may voice their views indirectly at the ballot box.
However, times are slowly changing. Many people have become dissatisfied with main stream media reports and become more willing to stand up against misleading advertising, destructive policies and rapidly rising costs. In my perception, the recent Brexit vote is a harbinger of more of such “rebellions” to come, some likely to be equally surprising.
