Al Rokerhas trekked to the Arctic yet again — this time for a NASA mission in Greenland to study the effects of climate change on the rapidly melting glaciers, and how sea levels are rising as a result.

Months after traveling to Alaska to study the effects of climate changeon the northernmost part of the United States,Today’slongtime weather anchor flew in August with NASA scientists on their first-everOceans Melting Greenland/OMGNASAmission to study just how fast the warming ocean is melting the region’s massive ice sheets.

The intrepid Today feature anchor and co-host of the morning show’s third hour will go in-depth about his thought-provoking trip next week as part of NBC News and MSNBC’s new, weeklongClimate in Crisisseries.

Starting Sunday, NBC News, MSNBC, Telemundo and NBC News Digital will dedicate the entire week’s programming to the climate crisis, showing howrapid changes in our environmentare affecting us here in the U.S. and in the rest of the world.

Roker isn’t the only one traveling the globe to report on theeffects of climate changefrom the ground.

During the series, NBC Nightly News anchor Lester Holt will report from Alaska, where he lived as a child while his father served in the U.S. Air Force. He will show howwarming temperaturesare melting the state’s famed Portage Glacier and thawing the permafrost, which countless communities depend on to survive.

“We’re seeing a shift in our very way of life because of climate change,” Roker, 65, tells PEOPLE. “We’re not trying to frighten people. We’re trying to show people how this affects your everyday life and in ways big and small.”

Trapped fossil fuel emissions are heating up the Earth’s atmosphere and causing Greenland’s ice sheets to melt at a rapid pace.

This “is important for us to see it firsthand” with some of the world’s most renowned scientists, he says.

“We were out with folks who had been on a glacier that was retreating at the rate of 10 to 15 feet a week,” he says.

During one point of his Arctic adventure, he says, “We were watching the glacier calve off.”

Greenland’s massive ice sheet melt wasn’t supposed to happen for many decades, according to scientists.

During his one-of-a-kind trip, Roker also flew with NASA in a DC-3 over Greenland’s shoreline, where he saw ice floes dotting the landscape.

While this is customary in summer, scientists are “seeing more (ice) break up, more quickly, over a wider expanse of time.”

As part of theClimate in Crisisseries, MSNBC’s Chris Hayes and Ali Velshi will moderate Climate Forum 2020, a two-day event where U.S. presidential candidates talk with young voters about their plans to lead the country — and the world — into an uncertain future.

The forum will live-streamed in part on NBC News Now and Telemundo and featured on MSNBC programming on Sept. 19 and 20.

Why?

“It’s the most important issue that human civilization has arguably ever faced — and certainly of the most important issues we face now,” says Hayes, 40.

Velshi, 49, says he wants to help viewers gain a more sophisticated understanding of where the candidates stand on the climate crisis. He also wants to ask the candidates what they think the world will look like in 2030 or 2050.

“In other words, how seriously do you take this?” he says. “There are implications in healthcare, in immigration, in national security, in nutrition — everywhere about this. I want to get a sense from these candidates about how they see it and more importantly, how do you convince people for whom climate change might be a fact but it’s not a priority?”

“I’ve covered a lot of hurricanes and I’ve seen a lot of devastation,” he says. “But this was like a hurricane and a tornado and an earthquake. It wasn’t the normal pattern of destruction that you see in a hurricane.”

Based on his discussions with climate experts over the years, he says, “We might be seeing a lot more of this.”

All the more reason to learn more about the climate crisis, Velshi says.

He says he hopes the forum “causes people to engage in the climate discussion to understand it better, regardless of what the political outcome is.”

“I also hope the viewer gets to understand where climate should be in their hierarchy of choice for a presidential candidate and what these presidential candidates will actually do about climate change.”

During the series, Hayes will also host a special live hour of MSNBC’sAll in with Chris Hayes, devoted exclusively to climate.

“To me, the biggest thing is conveying the urgency and the stakes, which are dire, without pushing people into a feeling of panic and impotence,” he says.
