A widely believed theory about the origins of Native Americans has been dealt a huge blow by a new genetic analysis of ancient teeth, implying the ancient inhabitants of what is now America were not who we thought they were.

The theory, largely based on archaeological evidence found at Native American sites, claims that the First Peoples came to the continent from Japan around 15,000 years ago. Stone tools and other stone artifacts used by Native Americans show similarities to those of the Jōmon people, a diverse hunter-gatherer people who lived in ancient Japan from around 14,000–300 BCE.

Based on this and analysis of their migration across the continent, it’s been suggested that Native Americans made their way across the northern rim of the Pacific Ocean, across the Bering Land Bridge – dry land that connected Siberia and Alaska during the last ice age – until they reached the northwest coast of North America.

Claiming 3rd place, we look at how a zero-electricity cooling system could meet the world’s growing AC needs.

The fact that as the Earth warms, the technology needed by humans to stay cool will only make the environment hotter is one of the great ironies of climate change.

Here’s where a novel device unveiled by MIT researchers in October comes in.

In theory, it could mitigate the effects of global warming; but experts are wary.

Make Sunsets, a California-based startup, released weather balloons that carried sulfur particles into the stratosphere which possibly burst there, releasing the chemical, MIT Technology Review.

Turning astrophysical data into audio has led to all sorts of surprising discoveries, from micrometeoroids bombarding spacecraft to lightning on Saturn. Now, there is a push to get more astronomers to use sonification.

Recently, a start-up company called Make Sunsets has begun releasing chemicals into the stratosphere as a form of geoengineering that is intended to help climate change. However, many are very hesitant about the startup and the result of what they are doing.

For perspective, geoengineering is when chemical particles are released into the stratosphere to manipulate the weather or climate. The theory is that when sulfur is released into the atmosphere that it mimics a natural process that occurs after volcanoes and that by doing this intentionally, we could ease global warming.

While it isn’t difficult to do this, it is very controversial. The reason for this is that it could potentially have dangerous side effects. Additionally, because some regions could endure worse side effects, it could cause issues across international lines.

The Royal Meteorological Society, which runs the Weather Photographer of the Year competition, has posed an intriguing question: Can artificial intelligence (AI) win a photography competition?

To answer this, the Society drew up a Turing test in which the viewer is invited to guess which is an AI image and which is an actual award-winning photo.

The Turing test, created by Alan Turing in 1950, is a test of a machine’s ability to exhibit intelligent behavior indistinguishable from a human.

While significant parts of the globe are already facing significant freshwater scarcity, the need for more freshwater is projected to increase in order to sustain the increasing global population and economic growth and adapt to climate change.

An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped. Now, researchers at the University of Illinois Urbana-Champaign (UIUC) have proposed a new infrastructure capable of harvesting oceanic water vapor as a solution to limited supplies of fresh water in various locations around the world.

The study evaluated 14 water-stressed locations across the globe for the feasibility of a hypothetical structure capable of capturing water vapor from above the ocean and condensing it into fresh water – and doing so in a manner that will remain feasible in the face of continued climate change.

Make Sunsets is already attempting to earn revenue for geoengineering, a move likely to provoke widespread criticism.

What Will A Future Climate Conference in 2051 Talk About, A Year After Net Zero?

COP27 just ended in Egypt. Will what was accomplished there impact the world and be reflected in conversations at conferences in 2051?
