Scientists peer into heart of hurricanes to improve intensity forecast

Posted by in category: climatology

AUSTIN, Texas (Reuters) — Despite advances in predicting where hurricanes are heading, forecasters are still struggling to determine a crucial factor in deciding emergency measures and evacuations: their intensity.

With a better way to predict a storm’s power, or intensity, people on the ground will be more prepared in knowing whether a hurricane headed their way will cause devastating floods and winds that can uproot trees like Maria, which devastated Puerto Rico last year, or just shake branches and rattle windows.

“The fact that we have a much better understanding of where these storms are going to go is a great first step. We sort of have half the circle filled in, and we need to get that other half filled in, which is that intensity component,” said Steve Bowen, director and meteorologist for insurer Aon Benfield’s Impact Forecasting team.

NASA director reverses on climate change, after 1 month

Posted by in categories: astronomy, climatology, education, environmental, ethics, existential risks, governance, government, lifeboat, science, space, sustainability

For millennia, our planet has sustained a robust ecosystem; healing each deforestation, algae bloom, pollution or imbalance caused by natural events. Before the arrival of an industrialized, destructive and dominant global species, it could pretty much deal with anything short of a major meteor impact. In the big picture, even these cataclysmic events haven’t destroyed the environment—they just changed the course of evolution and rearranged the alpha animal.

But with industrialization, the race for personal wealth, nations fighting nations, and modern comforts, we have recognized that our planet is not invincible. This is why Lifeboat Foundation exists. We are all about recognizing the limits to growth and protecting our fragile environment.

Check out this April news article on the US president’s forthcoming appointment of Jim Bridenstine, a vocal climate denier, as head of NASA. NASA is one of the biggest agencies on earth. Despite a lack of training or experience—without literacy in science, technology or astrophysics—he was handed an enormous responsibility, a staff of 17,000 and a budget of $19 billion.

In 2013, Bridenstine criticized former president Obama for wasting taxpayer money on climate research, and claimed that global temperatures stopped rising 15 years ago.

The Nuclear Reactor Renaissance: Space Exploration and National Security

Posted by in categories: climatology, nuclear energy, security, solar power, space travel, sustainability

The nuclear power sector is seeing a resurgence in innovation, supported by new policies and emerging technologies. The general public and various governments are starting to grasp the value of nuclear power as an alternative, sustainable energy source. Unlike renewables, such as wind and solar power, nuclear energy is not dependent on weather conditions for power generation, having a capacity factor of over 90 percent. Nuclear power is also more eco-friendly than natural gas and coal and its “carbon-free” attributes are seen as critical in the fight against climate change.

For decades, advancements in the nuclear power sector have been incremental and focused largely on making systems “walk away safe.” Today, the industry is pushing the boundaries and exploring applications for nuclear power in ways that have never before been considered.

BWXT is at the forefront of this nuclear renaissance. This 6,000-employee company operates on the model of letting capital drive strategy. BWXT is constantly evaluating new ways to ensure workers, funding, and policies are utilized in the most effective way possible. The company also analyzes the needs of numerous other industries to determine how nuclear power could provide innovative solutions.

Cooling buildings worldwide

Posted by in categories: climatology, health

About 40 percent of all the energy consumed by buildings worldwide is used for space heating and cooling. With the warming climate as well as growing populations and rising standards of living—especially in hot, humid regions of the developing world—the level of cooling and dehumidification needed to ensure comfort and protect human health is predicted to rise precipitously, pushing up global energy demand.

Much discussion is now focusing on replacing the greenhouse gases frequently used as refrigerants in today’s air conditioners. But another pressing concern is that most existing systems are extremely -inefficient.

“The main reason they’re inefficient is that they have two tasks to perform,” says Leslie Norford, the George Macomber (1948) Professor in Construction Management in the Department of Architecture. “They need to lower temperature and remove moisture, and doing both those things together takes a lot of extra energy.”

What if AI made actors immortal?

Posted by in categories: climatology, life extension, policy, robotics/AI

I’m not that interested in this on the movie end, because i think most movies already suck, and couldnt really get any worse.


AUDREY HEPBURN DIED in 1993, but in 2013 she nevertheless starred in an advertisement for Galaxy, a type of chocolate bar. She was shown riding a bus along the Amalfi coast before catching the eye of a passing hunk in a convertible. In 2016 Peter Cushing, who died in 1994, reprised his role as the villainous Grand Moff Tarkin in the Star Wars film “Rogue One”. Such resurrections are not new, but they are still uncommon enough to count as news. Yet advances in special effects—and, increasingly, in artificial intelligence (AI)—are making it ever easier to manufacture convincing forgeries of human beings.

In recent months this has led to concern that propagandists will use the technology to generate videos in which political figures appear to say compromising things. A video created by BuzzFeed, a news website, in April shows Barack Obama apparently saying “We’re entering an era in which our enemies can make it look like anyone is saying anything at any point in time,” for example. In May a Belgian political party produced a fake video of Donald Trump saying implausible things about Belgium’s climate policy. In both cases the video looks slightly off, and the voice is provided by an impersonator. But the technology is improving fast, prompting a dozen AI researchers to place bets on whether a fake video will disrupt America’s midterm elections later this year. (Tim Hwang, a Harvard academic, is overseeing the wager.)

The human physiological impact of global deoxygenation

Posted by in categories: climatology, existential risks, health, sustainability

Article (2017) about oxygen depletion. “There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We discuss the impact that global deoxygenation, over hundreds of generations, might have on human physiology. Exploring the changes between different native high-altitude populations provides a paradigm of how humans might tolerate worsening hypoxia over time. Using this model of atmospheric change, we predict that humans may continue to survive in an unprotected atmosphere for ~3600 years. Accordingly, without dramatic changes to the way in which we interact with our planet, humans may lose their dominance on Earth during the next few millennia.”

Biotic replacement and evolutionary innovation as a global catastrophic risk

Old, but excellent post:

Several times in evolutionary history, the arrival of an innovative new evolutionary strategy has lead to a mass extinction followed by a restructuring of biota and new dominant life forms. This may pose an unlikely but possible global catastrophic risk in the future, in which spontaneous evolutionary strategies (like new biochemical pathways or feeding strategies) become wildly successful, and lead to extreme climate change and die-offs. This is also known as a ‘biotic replacement’ hypothesis of extinction events.

Ocasio-Cortez’s climate plan is the only one that matches scientific consensus on the environment

Posted by in categories: climatology, economics, government, sustainability

Ocasio-Cortez’s 100%-renewable plan puts her in agreement with a coalition of US mayors who have committed to the goal of complete decarbonization within their own cities. But Ocasio-Cortez, who has an economics degree, also couples that plank with an economic plan she is calling the Green New Deal.


In a major upset on Tuesday night, Alexandria Ocasio-Cortez, a 28-year-old Latina democratic socialist from the Bronx, beat out the longtime US representative Joe Crowley in the New York primaries. In the overwhelmingly Democratic district, she is practically certain to win a seat in Congress during the general election in November.

Ocasio-Cortez’s climate-change platform would become the most progressive of that of any sitting Congressperson in the Democratic party—and her primary victory catapults that platform into the mainstream.

Chandra Space Telescope: Revealing the Invisible Universe

Posted by in categories: climatology, cosmology

The Chandra X-Ray Observatory is a NASA telescope that looks at black holes, quasars, supernovas, and the like – all sources of high energy in the universe. It shows a side of the cosmos that is invisible to the human eye.

After more than a decade in service, the observatory has helped scientists glimpse the universe in action. It has watched galaxies collide, observed a black hole with cosmic hurricane winds, and glimpsed a supernova turning itself inside out after an explosion.

The telescope – billed as one of NASA’s Great Observatories along with the Hubble Space Telescope, Spitzer Space Telescope and the Compton Gamma Ray Observatory – has been a public relations tool for the agency, as well. Its pictures are frequently used by NASA in press releases.
