Exploring the Runaway Greenhouse: Implications for Exoplanet Habitability

Posted by in categories: climatology, space, sustainability

Could Earth end up with a runaway greenhouse effect like Venus someday, and what could this mean for finding life on exoplanets? This is something a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers used a 3D global climate model to investigate if Earth is destined to develop a runaway greenhouse effect like the planet Venus, which precious studies speculate was once much like Earth long ago. This study holds the potential to bring awareness of the long-term consequences of climate change and what steps can be taken to mitigate the effects.

“Until now, other key studies in climatology have focused solely on either the temperate state before the runaway, or either the inhabitable state post-runaway,” said Dr. Martin Turbet, who is a research scientist at CNRS laboratories of Paris and Bordeaux and a co-author on the study. “It is the first time a team has studied the transition itself with a 3D global climate model and has checked how the climate and the atmosphere evolve during that process.”

Iceland volcano erupts near town after weeks of quake activity

Posted by in category: climatology

OSLO, Dec 18 (Reuters) — A volcano erupted late on Monday in southwest Iceland, spewing lava and smoke across a wide area after weeks of intense earthquake activity, the country’s Meteorological Office said, threatening a nearby town.

Fearing a significant eruption on the Reykjanes peninsula, authorities last month evacuated the nearly 4,000 inhabitants of the fishing town of Grindavik and closed the nearby Blue Lagoon geothermal spa.

“Warning: Eruption has started north of Grindavik by Hagafell,” the Met Office said on its website, noting that the eruption began only a few kilometres from the town and cracks in the ground stretched toward the village located about 40 km (25 miles) south-west of Iceland’s capital city Reykjavik.

Posted by in categories: climatology, governance, quantum physics, robotics/AI, sustainability

Juan Bernabé-Moreno is IBM’s director of research for Ireland and the United Kingdom. The Spanish computer scientist is also responsible for IBM’s climate and sustainability strategy, which is being developed by seven global laboratories using artificial intelligence (AI) and quantum computing. He believes quantum computing is better suited to understanding nature and matter than classical or traditional computers.

Question. Is artificial intelligence a threat to humanity?

Answer. Artificial intelligence can be used to cause harm, but it’s crucial to distinguish between intentional and malicious use of AI, and unintended behavior due to lack of data control or governance rigor.

AI Takes Over The Classroom: Alpha Helping Solve The Teacher Shortage

Posted by in categories: climatology, education, mathematics, robotics/AI

The teacher shortage crisis is a major concern, casting a shadow on educational quality across the globe. In this academic climate, the rise of AI in the classroom sparks both hope and skepticism. Alpha school is leading the way, devoid of traditional teachers and reliant on its AI-powered curriculum and “guide” system. This innovative approach offers a glimpse of a promising future where technology and human ingenuity merge to redefine education.

AI has become a game-changer in education by customizing learning experiences according to students’ individual learning styles and paces. Alpha’s app-based tutoring system is a prime example of this. It is personalized for each student’s strengths and weaknesses, a significant departure from the traditional “one-size-fits-all” classroom approach. For instance, consider a child who struggles with math concepts. AI can modify the exercises and explanations to suit their learning style, enabling them to understand the material better.

Moreover, this AI-driven education system offers instant and detailed feedback, which may be lacking in some schools. Such immediate response fosters a deeper understanding and encourages a more engaged learning process. This level of individualized attention is a powerful tool for enhancing knowledge and engagement.

The future of intelligence: artificial, natural, and combined

Posted by in categories: climatology, government, health, policy, Ray Kurzweil, robotics/AI, singularity, sustainability

Twenty-four years ago, Ray Kurzweil predicted computers would reach human-level intelligence by 2029. This was met with great concern and criticism. In the past six months technology experts have come around to agree with him. According to Kurzweil, over the next two decades, AI is going to change what it means to be human. We are going to invent new means of expression that will soar past human language, art, and science of today. All of the concepts that we rely on to give meaning to our lives, including death itself, will be transformed.\

Study reshapes understanding of mass extinction in Late Devonian era

Posted by in categories: climatology, existential risks, sustainability

Diverse and full of sea life, the Earth’s Devonian era—taking place more than 370 million years ago—saw the emergence of the first seed-bearing plants, which spread as large forests across the continents of Gondwana and Laurussia.

However, a near the end of this era has long been the subject of debate. Some scientists argue the Late Devonian mass extinction was caused by large-scale volcanic eruptions, causing global cooling. Others argue a mass deoxygenation event caused by the expansion of was to blame.

A recently published study in the journal Communications Earth & Environment led by researchers at IUPUI now posits that both factors played a role—and draws attention to the environmental tipping points the planet faces today.

Earth on verge of five catastrophic climate tipping points, scientists warn

Posted by in categories: biological, climatology, neuroscience

Recently, economists and behavioral scientists have studied the pattern of human well-being over the lifespan. In dozens of countries, and for a large range of well-being measures, including happiness and mental health, well-being is high in youth, falls to a nadir in midlife, and rises again in old age. The reasons for this U-shape are still unclear. Present theories emphasize sociological and economic forces. In this study we show that a similar U-shape exists in 508 great apes (two samples of chimpanzees and one sample of orangutans) whose well-being was assessed by raters familiar with the individual apes. This U-shaped pattern or “midlife crisis” emerges with or without use of parametric methods. Our results imply that human well-being’s curved shape is not uniquely human and that, although it may be partly explained by aspects of human life and society, its origins may lie partly in the biology we share with great apes. These findings have implications across scientific and social-scientific disciplines, and may help to identify ways of enhancing human and ape well-being.

Cooling Functions of Forests: Investigating Microclimate Mechanisms

Posted by in categories: climatology, sustainability

How do forests cool themselves during the summer? This is what a recent study published in Agricultural and Forest Meteorology hopes to find out as a team of international researchers investigated the forests cool themselves through water evaporation and shading. However, climate change could have drastic consequences towards this type of natural air conditioning, specifically from droughts that dry up the soil, disabling a forest’s ability to stay cool during hot months.

For the study, the researchers collected daily measurements over four straight summer seasons of soil moisture and air temperature across 54 sites in broadleaf forests throughout Central Europe. They discovered that shaded forests were typically 2 degrees Celsius (36 degrees Fahrenheit) cooler than temperatures outside the shaded forests. Additionally, they discovered that this cooling effect was driven by soil moisture with this cooling effect becoming less prevalent as soils become drier.

“The findings are alarming in the context of climate change as more frequent and more severe droughts may threaten the cooling functions of forests,” said Dr. Caroline Greiser, who is a landscape ecologist at Stockholm University and lead author of the study.
