Can Science Survive the Death of the Universe?

Posted by in categories: biotech/medical, climatology, cosmology, ethics, neuroscience, particle physics, science, sustainability

Let me back up a moment. I recently concurred with megapundit Steven Pinker that over the last two centuries we have achieved material, moral and intellectual progress, which should give us hope that we can achieve still more. I expected, and have gotten, pushback. Pessimists argue that our progress will prove to be ephemeral; that we will inevitably succumb to our own nastiness and stupidity and destroy ourselves.

Maybe, maybe not. Just for the sake of argument, let’s say that within the next century or two we solve our biggest problems, including tyranny, injustice, poverty, pandemics, climate change and war. Let’s say we create a world in which we can do pretty much anything we choose. Many will pursue pleasure, finding ever more exciting ways to enjoy themselves. Others may seek spiritual enlightenment or devote themselves to artistic expression.

No matter what our descendants choose to do, some will surely keep investigating the universe and everything in it, including us. How long can the quest for knowledge continue? Not long, I argued 25 years ago this month in The End of Science, which contends that particle physics, cosmology, neuroscience and other fields are bumping into fundamental limits. I still think I’m right, but I could be wrong. Below I describe the views of three physicists—Freeman Dyson, Roger Penrose and David Deutsch—who hold that knowledge seeking can continue for a long, long time, and possibly forever, even in the face of the heat death of the universe.

High-speed internet could be coming to Antarctica

Posted by in categories: climatology, education, internet

The proposed fiber optic cable could advance climate research and education.


The US National Science Foundation is proposing a fiber optic cable for their Antarctic research station, McMurdo. The cable which could potentially integrate with other research technology, could impact research and overall well-being of McMurdo’s visitors.

Trees found to reduce land surface area temperatures in cities up to 12°C

Posted by in categories: climatology, satellites

A team of researchers with the Institute for Atmospheric and Climate Science, ETH Zurich, has found evidence that indicates that stands of trees can reduce land surface area temperatures in cities up to 12°C. In their paper published in the journal Nature Communications, the group describes how they analyzed satellite imagery for hundreds of cities across Europe and what they learned.

Prior research has suggested that adding to cities can help reduce high air temperatures during the warm months—cities are typically hotter than surrounding areas due to the huge expanses of asphalt and cement that absorb heat. In this new effort, the researchers looked at possible impacts on land surface areas instead of air temperatures. Such temperatures are not felt as keenly as air temperatures by people in the vicinity because it is below their feet rather than surrounding them.

The work by the team involved analyzing data from satellites equipped with land surface temperature sensors. In all, the researchers poured over data from 293 cities across Europe, comparing land surface temperatures in parts of cities that were covered with trees with similar nearby urban areas that were not covered with trees. For comparison purposes, they did the same for rural settings covered in pastures and farmland.

Could Luxury Submarine Trips Thrive as an Alternative to Space Tourism?

Posted by in categories: climatology, space travel, sustainability

Deepsea submersible diving could compete with space tourism.

A form of luxury tourism is hitting the deep sea thanks to a small handful of firms providing state-of-the-art private submersibles to high-paying customers.

Accelerated renewables-based electrification paves the way for a post-fossil future

Posted by in categories: climatology, innovation

Cost-slashing innovations are underway in the electric power sector and could give electricity the lead over fossil-based combustion fuels in the world’s energy supply by mid-century. When combined with a global carbon price, these developments can catalyze emission reductions to reach the Paris climate targets, while reducing the need for controversial negative emissions, a new study finds.

“Today, 80 percent of all energy demands for industry, mobility or heating buildings is met by burning—mostly fossil—fuels directly, and only 20 percent by electricity. Our research finds that relation can be pretty much reversed by 2050, making the easy-to-decarbonise electricity the mainstay of global energy supply,” says Gunnar Luderer, author of the new study and researcher the Potsdam Institute for Climate Impact Research. “For the longest time, fossil fuels were cheap and accessible, whilst electricity was the precious and pricier source of energy. Renewable electricity generation—especially from solar photovoltaics—has become cheaper at breath-taking speed, a pace that most climate models have so far underestimated. Over the last decade alone prices for solar electricity fell by 80 percent, and further cost reductions are expected in the future. This development has the potential to fundamentally revolutionize energy systems.

The UN Is Engineering a Floating City. To Withstand a Category 5 Hurricane?

Posted by in categories: climatology, engineering, governance, habitats, sustainability

Because global warming and its associated risks are here to stay.

Global warming is causing many physical risks such as droughts, wildfires, and floods. According to the Intergovernmental Panel on Climate Change, global warming is essentially irreversible, which means these dangers will keep coming up. Luckily, some countries have started planning ahead.

The Busan Metropolitan City of the Republic of Korea, the UN-Habitat, and OCEANIX have joined forces to build the world’s first prototype sustainable floating city in order to get ahead of physical risks.

What’s in a flame? The surprising mystery of how soot forms

Posted by in categories: biological, climatology, health, particle physics, solar power, sustainability

Soot is one of the world’s worst contributors to climate change. Its impact is similar to global methane emissions and is second only to carbon dioxide in its destructive potential. This is because soot particles absorb solar radiation, which heats the surrounding atmosphere, resulting in warmer global temperatures. Soot also causes several other environmental and health problems including making us more susceptible to respiratory viruses.

Soot only persists in the atmosphere for a few weeks, suggesting that if these emissions could be stopped then the air could rapidly clear. This has recently been demonstrated during recent lockdowns, with some major cities reporting clear skies after industrial emissions stopped.

But is also part of our future. Soot can be converted into the useful carbon black product through thermal treatment to remove any harmful components. Carbon blacks are critical ingredients in batteries, tires and paint. If these carbons are made small enough they can even be made to fluoresce and have been used for tagging , in catalysts and even in solar cells.

Weather Warfare: Weather Modification Technology in Warfare

Posted by in categories: climatology, geoengineering, military

As the world becoming aware of the environment’s brittleness, more diversified and complex ways have been devised to modify it as a weapon of warfare. Now a new class of weapons more disastrous than nuclear warfare is on the horizon. For altering the environment, weather and climate modification technologies, are the methods that may be used to convert climate and weather systems into weapons of war. It refers to Operation Popeye, which aimed to extend the monsoon season in Southeast Asia.

Captain Orville had cautioned that “if an enemy nation solves the problem of weather control and gets into the position of controlling large-scale weather patterns before we can, the effects might be even more devastating than nuclear conflict”. In this article, we have discussed in-depth Weather Modification Technology in Warfare, and how this method of modern warfare can be used to destroy any country economically, Tactically, Strategically, and Covertly.
