Stephen Hawking's Final Warnings Urged World to Halt Climate Change

Stephen Hawking, one of the greatest minds on Earth, died peacefully at his home in Cambridge on Wednesday at the age of 76.

As well as being a renowned physicist whose groundbreaking theories helped us understand the complexities of space, time and the universe, the British professor also taught us about our home planet.


In his last years, Hawking used his platform to warn that human activity is causing irreversible planetary damage and that we must take action to halt climate change.

"Climate change is one of the great dangers we face, and it's one we can prevent," Hawking said in May.

Hawking frequently denounced climate change deniers, and even offered to pay their trip to Venus to illustrate the impact of greenhouse gases on a habitable planet. The global thinker also warned that the Brexit vote would damage scientific research in Britain and criticized President Donald Trump's decision to withdraw the U.S. from the Paris agreement.

"I am not denying the importance of fighting climate change and global warming, unlike Donald Trump, who may just have taken the most serious, and wrong, decision on climate change this world has seen," Hawking said last year about the Paris withdrawal.

In a 2016 lecture, he predicted that humanity has only 1,000 years left on Earth and we must find another planet to live on.

"[W]e must ... continue to go into space for the future of humanity," Hawking said. "I don't think we will survive another 1,000 years without escaping beyond our fragile planet."

According to Hawking, Earth and its inhabitants could soon be doomed. But, as he wrote in 2016, he's actually an "enormous optimist" for our future—that is, if we can learn to work together.

"Perhaps in a few hundred years, we will have established human colonies amid the stars, but right now we only have one planet, and we need to work together to protect it," he wrote. "To do that, we need to break down, not build up, barriers within and between nations."

"We can do this, I am an enormous optimist for my species; but it will require the elites, from London to Harvard, from Cambridge to Hollywood, to learn the lessons of the past year. To learn above all a measure of humility."

Hawking died from complications of Lou Gehrig's disease, which he suffered from since he was 20.

Land Use and Pollution Lead to More Male Snapping Turtle Babies, Researchers Find

The sex of reptiles like snapping turtles is determined by the temperature of the nest, with warmer temperatures leading to female births and colder temperatures leading to male babies. Because of this, climate change is projected to increase the number of female turtle births. However, scientists have discovered that other human impacts on the environment are leading to conditions that actually produce more males.

Organic Agriculture Is Going Mainstream, But Not the Way You Think It Is

By Jeremy L. Caradonna

One of the biggest knocks against the organics movement is that it has begun to ape conventional agriculture, adopting the latter's monocultures, reliance on purchased inputs and industrial processes.

‘Business Unusual’ Must Be the Mantra in Bonn as UN Climate Talks Resume Next Week

As the 2018 climate talks kick off under the auspices of the UN next week, "business unusual" must be the mantra delegations need heard resoundingly in Bonn, said the World Wildlife Fund (WWF).

Speaking ahead of the start of the meeting, Manuel Pulgar-Vidal, WWF's global climate and energy programme leader, said the window of opportunity to keep global temperature rise below 1.5°C is fast closing.

Climate Is a 'Threat Multiplier' But Not Primary Cause of East African Conflict and Displacement, Study Finds

While there are predictions that climate change will displace masses of people in the near future—an Environmental Justice Foundation study reported on by The Guardian put the number in the tens of millions within the next decade—some have indicated that the climate refugee crisis has already begun.

The Syrian civil war has been linked to a massive drought in the region, and former UN Secretary General Ban Ki-moon called the conflict in Darfur one of "the first climate wars" in 2007.

Did the Polio Vaccine Cause Cancer?

By Vanessa Schipani, FactCheck.org

Q: Did people develop cancer because of the polio vaccine?

A: There are no known cases, and it's very unlikely. In the 1950s and 1960s, people did receive polio vaccines contaminated with a virus that causes cancer in rodents. But research suggests this virus doesn't cause cancer in humans.

'Nowhere Is Immune': Researchers Find Record Levels of Microplastics in Arctic Sea Ice

Scientists found record levels of microplastics in Arctic sea ice, a study published Tuesday in Nature Communications revealed.

Researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) sampled ice from five Arctic Ocean regions and found up to 12,000 microplastic particles per liter (approximately 1.06 liquid quarts) of ice, an AWI press release reported.
