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.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges $1 Trillion to Curb Climate Threat
By Julia Conley
Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged more than $1 trillion over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
‘Plastic Is Lethal’: Groundbreaking Report Reveals Health Risks at Every Stage in Plastics Life Cycle
With eight million metric tons of plastic entering the world's oceans every year, there is growing concern about the proliferation of plastics in the environment. Despite this, surprisingly little is known about the full impact of plastic pollution on human health.
But a first-of-its-kind study released Tuesday sets out to change that. The study, Plastic & Health: The Hidden Costs of a Plastic Planet, is especially groundbreaking because it looks at the health impacts of every stage in the life cycle of plastics, from the extraction of the fossil fuels that make them to their permanence in the environment. While previous studies have focused on particular products, manufacturing processes or moments in the creation and use of plastics, this study shows that plastics pose serious health risks at every stage in their production, use and disposal.
Air pollution within the home causes 3.8 million deaths a year, according to the World Health Organization. A recent University of Colorado in Boulder study reported by The Guardian found that cooking a full Thanksgiving meal could raise levels of particulate matter 2.5 in the house higher than the levels averaged in New Delhi, the world's sixth most polluted city.
