‘Record-breaking’ floods leave Western Australia communities isolated, defence aircraft deployed for rescue

Record-breaking floods in Australia’s northwest have resulted in many communities getting isolated, Australia’s weather forecaster said on Sunday (January 8). Severe weather system Ellie has created an emergency situation in Kimberly, an area in the state of Western Australia which is about the size of California.

The town of Fitzroy Crossing, a community of around 1,300 people, has been among the worst hit, with supplies having to be airlifted in due to flooded roads.

The Bureau of Meteorology said on Sunday that rain had eased as the ex-cyclone shifted eastwards to the Northern Territory, but warned that “record breaking major flooding” continued in the Kimberley.

Overpopulation myth — Having kids will not destroy the planet. Perhaps it can even help

On January 2023, 60 minutes interviewed Paul Ehrlich, the author of the 1968 Population Bomb.

Although I agree with some of the points, like the destruction of habitat, and climate change, and those points indeed need addressing. the overpopulation arguments in the book and the interview have already been proven wrong, repeatedly.

The 18th century Malthusian catastrophe predictions never materialized. Thanks to modern technology, new clean energy sources, and modern agriculture, our planet doesn’t have an overpopulation problem despite having more people today than at ant time in history.

It’s okay to have more kids. Kids will not “destroy the planet”. They may actually help.

This video explain why.

Arctic Sinkholes I Full Documentary I NOVA I PBS

As the Artic warms permafrost (carbon frozen in time) is melting, what we once thought to be stable ground.

As the permafrost melts with warming temperatures sinkholes are on the rise which release methane gas.

What happens when methane gas is released into our atmosphere?

In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.

Happy holidays, you’re laid off: White-collar workers bear brunt of downturn

Senior corporate officers across the nation are wringing their hands. The 2023 economic climate is uncertain, but one thing is for sure—more layoffs are coming. In November 2022 alone, more than 80,000 layoffs were announced from tech giants like Meta, Amazon, and Twitter, as well as conventional companies like PepsiCo, Goldman Sachs, and Ford.

Downsizing is one of the most difficult things that leaders ever have to accomplish. How many should you let go? When should you do it? Who stays and who goes? What severance do you offer? How do you protect your diversity targets? How to maintain trust and productivity in those who get to stay?

Let too many go, too fast, and you could damage service and execution. Let too few go, too late, and you might lose money. Let the wrong people go and you may just create internal chaos. Getting this wrong can have enormous consequences on profitability, productivity, brand reputation, and stock price.

People may have crossed the Beringia much earlier than thought, new study claims

Bridge did not appear until roughly 35,700 years ago, fewer than 10,000 years before the last ice age peaked.

It is thought humans arrived in the Americas for the first time through the Bering Land Bridge. Now, researchers at the University of California Santa Cruz claim that Bering Land Bridge formed surprisingly late during the last ice age.

According to a recent study that reconstructs the history of water level at the Beringia, the Bering Land Bridge did not appear until roughly 35,700 years ago, fewer than 10,000 years before the last ice age peaked, as per the new study.

A comet not seen since 50,000 years will be visible again in early 2023

It’s called the C/2022 E3 (ZTF) comet.

A comet that last appeared in the night sky during the Ice Age will soon make a reappearance in February 2023, according to a NASA statement published last week. Called the C/2022 E3 (ZTF) comet, it orbits the sun every 50,000 years. It will now pass within 26 million miles of Earth on February 1st, 2023.

It could also be visible to the naked eye in mid-to-late January. The comet can be seen using binoculars and low-level telescopes when the skies are clear.

Using AI For Organizational Rightsizing: 5 Benefits For Decision Making

Senior corporate officers across the nation are wringing their hands. The 2023 economic climate is uncertain, but one thing is for sure—more layoffs are coming. In November 2022 alone, more than 80,000 layoffs were announced from tech giants like Meta, Amazon, and Twitter, as well as conventional companies like PepsiCo, Goldman Sachs, and Ford.

Downsizing is one of the most difficult things that leaders ever have to accomplish.

AI can offer objective performance evaluation to help managers decide who stays and who goes. AI software startups like GoFusion Perfacto and Entomo use data from employee productivity, attendance record, and other KPIs to help separate the star players from the rest on the basis of objective performance metrics.

This approach provides department heads a justification for their downsizing decisions, freeing both leaders and teams of the worst ills of purely subjective decision-making.

When put under pressure to downsize, it is human nature for managers to make decisions biased towards short-term needs. Retaining the talent most critically needed for your organization’s core business activities today makes sense in theory. But when that happens across the board, it can leave you unprepared to take on your most important future-facing strategic initiatives.

Native Americans Are Not Who We Thought They Were, Study Suggest

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.

MIT’s zero-electricity cooling system could tackle the hottest regions of the world

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.

The number of energy-intensive air conditioning systems is projected to quadruple to 14 billion by 2050, putting a strain on existing power grids. Better yet, the increase in cooling alone will account for a 0.5-degree Celsius rise in global temperatures, according to the World Economic Forum.
