This is one of those climate videos you’re likely to remember, have a hard time putting out of your thoughts.

That applies in particular to 16-year-old Swede Greta Thunberg, who virtually stole the show and left some in the audience at a recent World Economic Forum meeting deeply moved, some verging on tears.

Responding to adults’ always wanting to give youths reasons to be hopeful, Thunberg told the January meeting in Davos, Switzerland, “I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day.

“And then I want you to act. I want you to act as you would act in a crisis. I want you to act as if the house was on fire. Because it is.”

Weather Underground founder Jeff Masters warns in the video that serious risks will arise when “major droughts are affecting two major grain producing areas simultaneously.” The likely result? He anticipates rioting, mass starvation in some parts of the world, governments “going down,” and refugee crises as a result of millions of people being forced from their homes.

Two Europe-based climate scientists also chime in on the serious risks they see posed by climate change, and a CBS meteorologist points to an increasing number of wildfires and says the fire season in California is three to four months longer than in the 1970s.

NBC News reporter Katy Tur says governments worldwide “have either turned away or ignored the problem.

“It has been going on for decades, and it’s getting worse today,” she said in an NBC broadcast excerpted in the video, produced by videographer Peter Sinclair.

“How pointless is my life, and how pointless are the decisions I am making on a day-to-day basis, when we are not focused on climate change every day, when it’s not leading every one of our newscasts?” Tur asks rhetorically.

“Yes, we are failing, but we can still turn this around,” Thunberg concludes. “We can still fix this. We still have everything in our own hands.”

“We have not come here to beg world leaders to care,” she says. “You have ignored us in the past, and you will ignore us again. We have run out of excuses and we have run out of time. We have come here to let you know that change is coming, whether you like it or not. The real power belongs to the people.”
