Another Plan to Save the Planet Hits Rock Bottom

A promising way to rid Earth’s atmosphere of excess carbon dioxide runs into a major stumbling block.

It’s always frustrating when scientists come up with some neat-o way to save the earth from the ravages of man, only to later decide it might not actually work.

Climate change 101: excess carbon dioxide in the air is not good. You want some CO2 in the air to regulate the temperature, but the fact that CO2 was 280 ppm (parts per million) at the start of the Industrial Revolution and is now 395 ppm (thanks mainly to the burning of fossil fuels), does not rest easy in the mind. So some scientists came up with an ingenious way of dealing with this: inject the gas 7,000 feet deep below the Earth’s surface, where it will turn to rock and stay there. So we could just make all the CO2 we wanted and then turn it into rock? Wow. Where do we sign up?

Well, right now, nowhere. Because scientists are discovering that only a fraction of this injected CO2 turns to rock. The issue, put very, very simply, is that once some of the CO2 reacts with the chemicals in the environment its injected into, it turns solid—like it is supposed to—but then that mass creates a block, which the remaining CO2 injected along with it can’t get past. So the CO2 just hangs out there in gas or liquid form, and then, eventually, makes its way back into the atmosphere, putting everyone, more or less back at square one.

Scientists pioneering this solution are not giving up, trying to find ways to solve or get around the clogging problem. In the meantime, CO2 levels are rising about 2 ppm a year.

Young leaders from around the world are gathering at the United Nations Headquarters in New York Saturday to address arguably the most urgent issue of our time. The Youth Climate Summit comes on the heels of an international strike spearheaded by Greta Thunberg, the 16-year-old climate activist from Sweden, who arrived in New York via emissions-free sailboat earlier this month.

Translated from Swedish, "berg" means "mountain," so it may feel fated that a young woman with Viking blood in her veins and summit in her name would be at the helm. But let's go out on a limb and presume Thunberg, in keeping with most activists, would chafe at the notion of pre-ordained "destiny," and rightly so. Destiny is passive — it happens to you. It's also egomaniacal. Change, on the other hand, is active; you have to fight. And it is humble. "We need to get angry and understand what is at stake," Thunberg declared. "And then we need to transform that anger into action."

This new generation of activists' most pernicious enemy is denial. The people in charge — complacent politicians and corporation heads who grossly benefit from maintaining the status quo — are buffered from real-life consequences of climate change. But millions of people don't share that privilege. For them, climate change isn't an abstract concept, but a daily state of emergency, whether it comes in the form of "prolonged drought in sub-Saharan Africa…devastating tropical storms sweeping across Southeast Asia, the Caribbean and the Pacific…[or] heatwaves and wildfires," as Amnesty International reportsare all too real problems people are facing on a regular basis.

Millions of people in over 150 countries across the globe marched for lawmakers and corporations to take action to help stop climate change on Friday, September 20.

The Climate Strikes were organized by children around the world as an extension of the of the "Fridays for Future" campaign. Students have been walking out of classrooms on Fridays to speak out about political inaction surrounding the climate crisis.

"We need to act right now to stop burning fossil fuels and ensure a rapid energy revolution with equity, reparations and climate justice at its heart," organizers say.

There's no doubt the visual images from the marches send a powerful message to those on the ground but especially those watching from around the world. GOOD's own Gabriel Reilich was on the scene for the largest of the Climate Strikes. Here are 18 of the best signs from the Climate Strike march in New York City.

September 20th marks the beginning of a pivotal push for the future of our planet. The Global Climate Strike will set the stage for the United Nations Climate Action Summit, where more than 60 nations are expected to build upon their commitment to 2015's Paris Agreement for combating climate change.

Millions of people are expected to take part in an estimated 4,000 events across 130 countries.

When the iPhone 11 debuted on September 10, it was met with less enthusiasm than the usual iPhone release. A lot of techies are holding off purchasing the latest gadget until Apple releases a phone with 5G technology.

Major US phone carriers have yet to build out the infrastructure necessary to provide a consistent 5G experience, so Apple didn't feel it necessary to integrate the technology into its latest iPhone.

A dramatic new feature on the iPhone 11 Pro is its three camera lenses. The three lenses give users the the original wide, plus ultrawide and telephoto options.

We often dismiss our dreams as nonsensical dispatches from the mind while we're deep asleep. But recent research proves that our dreams can definitely affect our waking lives.

People often dream about their significant others and studies show it actually affects how we behave towads them the next day.

"A lot of people don't pay attention to their dreams and are unaware of the impact they have on their state of mind," said Dylan Selterman, psychology lecturer at the University of Maryland, says according to The Huffington Post. "Now we have evidence that there is this association."
