What NASA's 20-year time-lapse of Earth shows

  What NASA's 20-year time-lapse of Earth shows Unprecedented space-based view sheds light on global warming and shows the planet literally "breathing.""It's one of a kind. It's never been done before and so being able to capture land, ocean, atmosphere, ice, over 20 years together -- it's insanely cool," NASA oceanographer Dr. Jeremy Werdell told CBS News correspondent Chip Reid.

America Recycles Day is on Wednesday, and the green holiday exists for good reason: Recycling helps keep rubbish off the roads, reduces the need for Earth-scarring metal-mining operations, and fuels industry jobs.

The practice also keeps planet-warming carbon dioxide out of the air. Every ton of recycled aluminum cans (about 625 of them), in fact, keeps 10 tons of CO2 out of the atmosphere, according to Popular Mechanics.

Recycling is no panacea, though. An ever better idea is to curb carbon emissions, though President Donald Trump has vowed to withdraw the US from the Paris climate accord.

This is what the Earth could look like within 100 years if we succeed in curbing climate change with international agreements like the Paris climate accord (barring huge leaps in renewable energy or carbon-capture technology).

That globally denounced decision came on the heels of the hottest year the world has seen since 1880 — when scientists started keeping global temperature logs — and the fifth annual heat record of the past dozen years. In 2016, planet Earth's temperature averaged 2.3 degrees Fahrenheit (1.26 degrees Celsius) above preindustrial averages, which is dangerously close to the 1.5-degree-Celsius limit set by international policymakers.

"There's no stopping global warming," Gavin Schmidt, a climate scientist who is the director of NASA's Goddard Institute of Space Studies, previously told Business Insider. "Everything that's happened so far is baked into the system."

That means that even if carbon emissions were to drop to zero tomorrow, we'd still be watching human-driven climate change play out for centuries. And we all know emissions aren't going to stop immediately. The key thing now, Schmidt said, is to slow climate change down enough to allow us to adapt as painlessly as possible.

Bizarre Lava-Covered Planet's Air Could Support Life

  Bizarre Lava-Covered Planet's Air Could Support Life But don't book your tickets yet—this place is definitely too hot to handle.That distant planet, known as 55 Cancri e, has been entrancing scientists since they first spotted it in 2004. It's skewed with respect to its star, its core may be basically a giant diamond, and its surface is covered in lava. It's pretty hard to turn away from a combination like that.

This is what the Earth could look like within 100 years if we succeed in curbing climate change with international agreements like the Paris climate accord (barring huge leaps in renewable energy or carbon-capture technology).

"I think the 1.5-degree [2.7-degree F] target is out of reach as a long-term goal," Schmidt said. He estimated that we will blow past that by about 2030.

But Schmidt is more optimistic about keeping temperatures from rising more than 3.6 degrees F, or 2 degrees C. That's the increase the UN hopes to avoid.

Let's assume that we land somewhere between those two targets. At the end of this century, we'd be looking at a world that is on average about 3 degrees Fahrenheit above where we are now.

But average surface temperature alone doesn't paint a full picture. Temperature anomalies — how much the temperature of a given area deviates from what would be "normal" in that region — will swing wildly.

For example, the temperature in the Arctic Circle soared above freezing for one day in 2016 — that's extraordinarily hot for the arctic. Those types of abnormalities will start happening a lot more.

That means years like 2016, which had the lowest sea-ice extent on record, will become more common. Summers in Greenland could become ice-free by 2050.

In the summer of 2012, 97% of the Greenland Ice Sheet's surface started to melt. That's typically a once-in-a-century occurrence, but we could see extreme surface melt like that every six years by end of the century.

On the bright side, ice in Antarctica will remain relatively stable, making minimal contributions to sea-level rise.

However, unexpected ice shelf collapses could surprise researchers with extra sea-level rise.

Even in our best-case scenarios, oceans are on track to rise 2 to 3 feet by 2100. That could displace up to 4 million people.

Oceans absorb about one third of all carbon dioxide in the atmosphere, causing them to warm and become more acidic. Rising temperatures will therefore cause oceans to acidify more around the globe.

In the tropics, that means nearly all coral reef habitats could be devastated. Under our best-case scenario, half of all tropical coral reefs are threatened.

And even if we curb emissions, summers in the tropics could see a 50% increase their extreme-heat days by 2050. Farther north, 10% to 20% of the days in a year will be hotter.

Without controlling our emissions (a business-as-usual scenario), the tropics would stay at unusually hot temperatures all summer long. In the temperate zones, 30% or more of the days would have temperatures that we currently consider unusual.

Even a little bit of warming will likely strain water resources. In a 2013 paper, scientists projected that the world will start to see more intense droughts more often. Left unchecked, climate change may cause severe drought across 40% of all land — double what it is today.

And then there's the weather. If the extreme El Niño event of 2015-2016 was any indication, we're in for more natural disasters — storm surges, wildfires, and heat waves are on the menu for 2070 and beyond.

Newly discovered nearby planet could support life

  Newly discovered nearby planet could support life Ross 128 b is a newly discovered exoplanet, the second-closest found to our solar system, only 11 light-years away. And it could support life. Announcements about exoplanets, those found outside our solar system, seem almost commonplace in this golden age of discovery for astronomers. So why is Ross 128 b unique -- apart from its rather human-sounding name? The planet is about the same size as Earth, and it may have a similar surface temperature, making it a temperate world that could support life. Every 9.

President Donald Trump on Thursday announced his intent to withdraw the US from the Paris climate accord. " We ' re getting out, but we will start to negoatiate to see if we can make a deal that is fair," Trump claimed during a televised briefing from the White House. Trump' s widely denounced.

Right now, humanity is standing on a precipice. If we ignore the warning signs, we could end up with what Schmidt envisions as a "vastly different planet" — roughly as different as our current climate is from the most recent ice age.

Or we can innovate. Many best-case scenarios assume we'll reach negative emissions by 2100 — that is, absorb more than we emit through carbon-capture technology.

Schmidt says the Earth in 2100 will be somewhere between "a little bit warmer than today and a lot warmer than today." On a planet-wide scale, that difference could mean millions of lives saved, or not.
