Researchers say cooling 13,000 years ago is coincident with major volcanic eruption.
Texas researchers from the University of Houston, Baylor University and Texas A&M University have discovered evidence for why the earth cooled dramatically 13,000 years ago, dropping temperatures by about 3 degrees Centigrade.
The evidence is buried in a Central Texas cave, where horizons of sediment have preserved unique geochemical signatures from ancient volcanic eruptions — signatures previously mistaken for extraterrestrial impacts, researchers say.
As earth becomes less habitable due to the climate emergency, The Astroland Agency are working out how humans could colonize Mars by 2035. Before the pandemic, we spent time with them to learn how that would work.

At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, mostly hidden from the prying eyes of humans, is a collection of swirling storms arranged in an unusually geometric pattern.
Since they were first spotted by NASA’s Juno space probe in 2019, the storms have presented something of a mystery to scientists. The storms are analogous to hurricanes on Earth. However, on our planet, hurricanes do not gather themselves at the poles and twirl around each other in the shape of a pentagon or hexagon, as do Jupiter’s curious storms.
Now, a research team working in the lab of Andy Ingersoll, Caltech professor of planetary science, has discovered why Jupiter’s storms behave so strangely. They did so using math derived from a proof written by Lord Kelvin, a British mathematical physicist and engineer, nearly 150 years ago.
Introduction: In recent years a futurist aesthetic movement has emerged in response to renewed public concern for the environment and a seeming lack of reflection of that concern in much contemporary art and design. Deriving its name from similar aesthetic movements such as Cyberpunk and Steampunk, its roots lay in various eco/climate science fiction and Post-Industrial futurist literature and is considered ‘punk’ in the sense that it is reactionary, and in opposition, to both the naive corporate utopianism that dominated the 20th century and the dystopianism that emerged in its wake by the end of that century, persisting to the present. We now live in an era where pragmatism is a radical stance. Thus Solarpunk seeks to cultivate a positive, hopeful, vision of a future rooted in technologies and culture of sustainability, yet in the context of what it acknowledges will be dramatic changes in our way of life due to Global Warming and the environmental malfeasance of the past, the transition to a renewables-based infrastructure, and the collapse of Industrial Age paradigms. A culture that has weathered the dramatic disruptions coming with the end of the Industrial Age, taken its sometimes bitter lessons from that, and found a way forward.
What makes Solarpunk ‘punk’ is an underlying activist/revolutionary narrative it shares with the earlier punk movements tracing its origins to the narrative of one of Science Fiction’s earliest ‘antiheroes’; Captain Nemo of Jules Verne’s 20,000 Leagues Under The Sea. Long mischaracterized in film, the original character of Nemo is an Indian victim of European colonialism who is radicalized by the murder of his family by colonialists. He then appropriates and improves upon the technology of the colonialist powers not just to fight against them but to create a model egalitarian society of the future in the secret haven of the underwater underworld, beyond the reach of those colonial powers. Thus he becomes the prototype tech-hero, turning the oppressors/dominators technology against them and repurposing it for the benefit of the rest of society.
A third — the most out-there among the three — is designed to seat 200 passengers. The concept merges the wings with the main body, creating a massive open space. “The exceptionally wide fuselage opens up multiple options for hydrogen storage and distribution, and for cabin layout,” an Airbus statement reads.
Airbus is hoping to drum up excitement around the idea of powering the planes of tomorrow using hydrogen gas. “The transition to hydrogen, as the primary power source for these concept planes, will require decisive action from the entire aviation ecosystem,” Airbus CEO Guillaume Faury said in the statement.
“I strongly believe that the use of hydrogen — both in synthetic fuels and as a primary power source for commercial aircraft — has the potential to significantly reduce aviation’s climate impact,” he added.
Discovering chemical substances as possible chemical markers of life existence in Venus’s atmosphere via remote astronomical observations cannot be considered objective evidence of life existence on the planet, says Roscosmos Executive Director for Science and Advanced Programs Alexander Bloshenko. ‘Credible scientific data on that matter can be obtained only via contact explorations of the planet’s surface and atmosphere,’ he added.
Notably, the USSR was the only country to conduct regular explorations of Venus using on-planet stations. The first ever soft landing on another planet’s surface in the Solar system was performed in 1970 by the Venera-7 descent module. Several orbital missions and landings provided detailed data on the Venerian climate, soil and atmosphere composition. The Soviet Venera-13 spacecraft still holds the record as the longest active spacecraft on Venus remaining operational for 127 minutes.
A huge breakaway of the Soviet Union from its competitors in exploration of Venus contributed to the fact that USA called Venus a ‘Soviet planet’. Having recently analyzed the pictures of Venus captured by Soviet missions, scientists of the Russian Academy of Sciences claimed they discovered moving objects and even might be living. And it remains to be seen, whether these guesses are true.
Today, a program of complex exploration of Venus has been developed by Roscosmos in cooperation with the Russian Academy of Sciences. The program consists of several missions. Moreover, a decision was taken to implement the previously planned Venera-D mission including orbital and landing modules, as a national project without involving wide international cooperation. The complex explorations will also include soil and atmosphere samples, as well as exploring evolution processes on Venus that has purportedly suffered a climatic disaster connected with greenhouse effect that is much discussed on Earth today.
While the future of the clean energy proposal remains uncertain, the majority of Americans have been reading from the same page regarding what needs to be done: Dramatically cutting down the country’s reliance on fossil fuels over the next two decades is critical to lowering greenhouse gas (GHG) emissions and address climate change, with six in 10 U.S. adults saying they would favor policies with this energy goal. Thankfully, scientists have been researching alternative energy solutions like wind and solar power for decades, including lesser-known sources that may seem a little unusual or even downright ridiculous and unrealistic.
You can chalk up harvesting energy from blackholes to the latter category.
Fifty years ago, British mathematical physicist, Roger Penrose, proposed a seemingly absurd idea how an alien society (or future humans) could harvest energy from a rotating black hole by dropping an object just outside its sphere of influence also known as the ergosphere where it could gain negative energy. Since then, nobody has been able to verify the viability of this seemingly bizarre idea— that is until now.

How cool would it be if we could one day regulate our atmosphere, control the climate and maybe even blast threatening asteroids into stardust? Well, to do those things would require A LOT of energy. Essentially, we’d have to be able to harness all the power from the Sun. According to the Kardashev scale that ranks planets according to their ability to harness the energy from their star and even their galaxy, that would make Earth a Type II civilization. What does that mean and how far away are we from achieving that level of uber energy capacity? You’ll have to tune in to find out as Peter and Richard welcome back Michio Kaku, physicist and science communicator extraordinaire to help us better understand “What If we became a type II civilization?”

The coronavirus is a stark reminder of the devastating damage that could be inflicted by cyberattacks, superbugs, freak weather and a variety of other threats. These wild cards are in addition to the existential challenge posed by climate change, gross inequality, financial meltdowns, autocratic governments, terrorism and other massive problems collectively called the Global MegaCrisis.
I sense the world is so frightened by recent disasters that people are searching for new solutions. They seem ready to break from the past that is no longer working. Climate change is starting to bite, for instance, and there is a growing consensus that the status quo is no longer sustainable.
I have studied this dilemma for decades, and I think it can be best understood as a transition to the next stage of social evolution. The Knowledge Age that dominated the last two decades is fading into the past as AI automates knowledge, forcing us to move beyond knowledge and develop a global consciousness able to resolve the MegaCrisis.
Yes, I know this is a bold claim, but that is how the shift to a world of knowledge looked 40 years ago. When computers filled rooms, I recall telling people that we were entering a world of personal computers. The typical response was “Why would anyone want a personal computer?”
Just so, today’s post-factual era illustrates how the smart phone, social media, and autocrats like Trump have moved public attention beyond knowledge and into a world of values, emotions and beliefs. Now the challenge is to use these new powers of social media to shape a global consciousness, or face disaster. While this may seem impossible, that is always the case before major upheavals. Nobody thought the USSR would collapse up until its very end.
In fact, the Business Roundtable’s recent announcement that business should move beyond the bottom line to include the interests of all stakeholders is revolutionary. It has now been promulgated by the World Economic Forum and other influential bodies. The gravity of this change is such that business is now being told to help resolve the climate crisis. Larry Fink, who runs the biggest investment firm in the world (Black Rock), directed the companies he owns to help address climate costs in their operations; within days, many firms announced climate plans.
This historic shift in consciousness could make corporations models of cooperation for society at large. In short, I think the world is heading toward some type of historic shift in consciousness, a collective epiphany, a code of global ethics, a spiritual revolution, a political paradigm shift or a new mindset. Without a consciousness based on global unity, cooperation and other essential beliefs, there seems little hope. And with a shift to global consciousness, it all seems possible.
Toward a Global Consciousness
The governing ideas inherited from the industrial past are outdated and heading toward disaster. It is a collapse of today’s reigning “materialist” ideology of Capitalism, economic growth, money, power, self-interest, rationality, knowledge, etc. These values remain valid and useful, of course, but they are now badly limited. Prevailing practices in the US, as the most prominent example, are failing to address the climate crisis, low wage employee welfare, universal health care, women’s rights, political gridlock, aging infrastructure and other social issues that lie beyond sheer economics.
This could become a “Collapse of Capitalism” roughly equivalent to the “Collapse of Communism” in the 1990s, and it stems from the same fatal flaw – failure to adapt to a changing world. Communism could not meet the complex demands of the Information Revolution, and now Capitalism seems to be failing to adapt to a unified globe threatened by pandemics, climate change and the other threats making up the MegaCrisis.
The big question remaining is, “What should be the new vision, values, principles, and policies?” At the risk of appearing pedantic, I integrate what has been learned above and my forthcoming book, Beyond Knowledge, to outline five principles of what I consider “global consciousness.”
1. Treat the planet and all life forms as sacred. The Fermi Paradox notes that no other civilizations have been detected after decades of SETI searching. This rarity of life reminds us what a miracle plant Earth really is, and that we are responsible for its well-being.
2. Govern the world as a unified whole. Nations remain the major players in this global order, but they should be lightly governed by some type of global institution like the UN and other international bodies. Individuals should continue to be loyal to their nations and local institutions, but they should also accept their role as global citizens.
3. Collaborate With All Stakeholders. Free enterprise is the basis of society, and the good news is that business is on the verge of becoming cooperative. The Business Roundtable announcement that all stakeholders should be treated equally with investors seems an historic breakthrough. This move to a quasi-democratic form of enterprise could set a new standard for collaborative behavior and human values throughout modern societies. One of the benefits from a tragedy like this crisis may be a loss of faith in the status quo and an urge to cooperate. I see it everywhere, and it is a blessing in disguise emerging out of chaos.
4. Embrace diversity as an asset. Rather than becoming a uniform pallid bureaucracy, a unified world should embrace the wondrous diversity of cultures and individuals. Working across such differences poses a challenge, naturally, but differences are also a source of new knowledge, talents and human energy.
5. Celebrate Community. Any society needs frequent opportunities to gather together in good spirit, enjoy differences and commonalities, and to simply celebrate the glory of life. The World Olympics Games, for instance, are special because they provide a rare feeling of global community. We could witness a flowering of celebratory events over the coming years to nourish the global soul.
Shaping Consciousness
This is only one small study, of course, but I hope it provokes thinking toward a widely held vision for planet Earth at a time of crisis. An historic change in consciousness is hardly done overnight, and the obstacles posed by the status quo are formidable. But the Information Revolution provides a powerful method for shaping consciousness by using the Internet and public media. Think of the explosion of ideas, hatred and forbidden desires released by billions of people blasting into loudspeakers like Facebook and Twitter. Anybody can use the media to shape public opinion instantly, for better or worse.
The task we face is to shape a unified consciousness out of this morass of differences to solve the global crises that loom ahead. Today’s threats to reason is challenging us to counter wrongheaded beliefs and to provide more attractive visions, such as the principles for global consciousness outlined here. I suggest the place to begin is by discussing these ideas as widely as possible, and to shape public opinion roughly along these lines.
