Joe Biden Delivers Delaware Commencement Speech

NEWARK, Del. (AP) — Today’s college graduates are stepping into a rapidly changing world that presents profound dangers and challenges as well as incredible opportunities, Vice President Joe Biden said Saturday in a commencement speech at his alma mater, the University of Delaware.

A sense of confidence and an optimistic attitude will enable the newest class of graduates not only to confront those challenges and make the most of them, just as previous generations of Americans have done, but “to bend history a little bit,” the vice president said.

“Once every couple of generations, a class enters a point in our history where they actually have a chance to change the trajectory of the country, an inflection point, where change is taking place,” Biden said.

Biden’s speech was his fourth commencement address at the university, from which he graduated in 1965 with a double major in history and political science. Today, just as when he graduated from the university, America is again at such a point of change, Biden asserted.

Whereas the nation in the 1960s was roiled by the nuclear arms race, the civil rights movement, political assassinations and the Vietnam War, the challenges today are different, but no less daunting, said Biden, ticking off a list that includes international terrorism, pandemic disease, climate change and global inequity.

“Today, stateless actors not only create a threat, but an opportunity. They’re bringing together civilized nations in a common cause to wipe them out,” he explained. “The effects of climate change are real and must be acted on. They’re generating phenomenal breakthroughs and rapid growth of renewable energy.”

Similarly, the fear of pandemic disease has led a generation of scientists and doctors to find new tools not just to prevent disease, but to cure illnesses once thought incurable, and medical and scientific advances continue at a breakneck pace, he said.

Meanwhile, America remains the world’s economic leader and a nation that embraces “equity, fairness and justice,” Biden noted.

“Consider the progress we’ve made just since you’ve been here in civil rights,” he said to the applause of graduates. “The right to marry the person you love. The right of a woman to make her own health care decisions. The right of millions of people living in the shadows to earn a pathway to citizenship.”

Biden urged graduates to embrace the future with a sense of confidence.

“You are citizens of the nation that is better positioned than any country in the world to lead the 21st century, economically, politically, socially,” he said. “…. Neither optimism nor pessimism enables you to predict your future, but I am absolutely confident that only confidence and an optimistic attitude will enable you to take a hand in shaping your future.”

Biden’s speech was his fourth commencement address at the university, from which he graduated in 1965 with a double major in history and political science. In 2011, he donated his senatorial papers to the school.

Obama gears up for his big climate move

Obama gears up for his big climate move

President Obama is about to launch the biggest climate change initiative of his presidency — the biggest in U.S. history — and it’s not because he’s a tree-hugging hippie. As he lays the groundwork for introducing landmark regulations on power-plant CO2 emissions on Monday, he “wants to shift the conversation from polar bears and melting glaciers to droughts in Iowa and more childhood asthma across the nation,” as Bloomberg reports.

He pushed that message home in his weekly video address on Saturday:

I’m here at Children’s National Medical Center in Washington, D.C., visiting with some kids being treated here all the time for asthma and other breathing problems. Often, these illnesses are aggravated by air pollution — pollution from the same sources that release carbon and contribute to climate change. And for the sake of all our kids, we’ve got to do more to reduce it. …

This week, we’re unveiling … proposed guidelines [that] will cut down on the carbon pollution, smog, and soot that threaten the health of the most vulnerable Americans, including children and the elderly. In just the first year that these standards go into effect, up to 100,000 asthma attacks and 2,100 heart attacks will be avoided — and those numbers will go up from there.

On Friday, Obama linked climate change to the storms and weather disruptions that Americans are already seeing in their hometowns, echoing the message of the big climate report that his administration put out in early May. During a meeting at the headquarters of the Federal Emergency Management Agency, or FEMA, he said:

The changes we’re seeing in our climate means that, unfortunately, storms like Sandy could end up being more common and more devastating. And that’s why we’re also going to be doing more to deal with the dangers of carbon pollution that help to cause this climate change and global warming.

Earlier in the week, in a big speech on his foreign policy agenda, the president warned that climate change is also “a creeping national security crisis.”

Yep, no polar bear mentions.

Obama has not gotten into specifics about the forthcoming regulations — we’ll have to wait for Monday for the details — but, in his address on Saturday, he did warn Americans not to believe the dirty-energy interests that are preemptively bashing the regs.

Now, special interests and their allies in Congress will claim that these guidelines will kill jobs and crush the economy. Let’s face it, that’s what they always say.

But every time America has set clear rules and better standards for our air, our water, and our children’s health — the warnings of the cynics have been wrong. …

These excuses for inaction somehow suggest a lack of faith in American businesses and American ingenuity. The truth is, when we ask our workers and businesses to innovate, they do. When we raise the bar, they meet it. …

In America, we don’t have to choose between the health of our economy and the health of our children. The old rules may say we can’t protect our environment and promote economic growth at the same time, but in America, we’ve always used new technology to break the old rules.

The fossil fuel industry and the U.S. Chamber of Commerce will paint the proposed regulations as environmental extremism run amuck. Obama and his allies will argue that climate action is needed to protect things mainstream Americans care about deeply — their health, the economy, national security, their very homes.

It’s not about dirty fucking hippies. It’s about organic apple pie.

Vintage Photos Of Apollo Astronauts Training In Hawaii Unearthed

HONOLULU (AP) — Before Apollo astronauts went to the moon, they went to Hawaii to train on the Big Island’s lunar landscapes.

Now, decades-old photos are surfacing of astronauts scooping up Hawaii’s soil and riding across volcanic fields in a “moon buggy” vehicle.

The Pacific International Space Center for Exploration Systems, a Hawaii state agency, is displaying the photos at its Hilo headquarters. Rob Kelso, the agency’s executive director, found the images at the Johnson Space Center in Houston.

Astronauts from Apollo missions 13 through 17 trained in Hawaii as did some back up crews, Kelso said.

Some training was on Mauna Kea volcano, where glacial runoff crushed and refined rock into powder. Astronauts also trained on recent lava flows.

Today, robots are tested on the Big Island for moon and Mars missions.

In recent years, engineers have tested technology to pull oxygen out of the island’s dirt, which is volcanic basalt like the Martian and lunar soil. Future missions could use this technology to extract oxygen from the land instead of taking it along. The oxygen could be used for breathing, to make fuel or for other purposes.

Kelso said scientists are also interested in testing robots at the Big Island’s lava tubes and lava tube skylight holes, which resemble similar formations recently spotted in high-definition images taken by satellites orbiting the moon, Mercury, Venus and Mars.

Lava tubes are tunnels made when lava forms a solid roof after flowing steadily in a confined area for hours. Skylight holes are formed when part of the tube breaks.
