"In both cases, its just empty words", she said to a roaring crowd in Montreal Friday afternoon.
While many were able to appreciate the joke, Thunberg's United Nations speech and her "Fridays for future" movement has been taken very seriously by both the establishment and the mass media, as well as plenty of her followers.
Without naming the United States president, Thunberg said she didn't "understand why grown-ups would choose to mock children and teenagers for just communicating and acting on the science when they could do something good instead".
Daphnee Choquette said she came out for her baby girl, whom she carried with her. This is an emergency, and we will not be bystanders. "We will not be bystanders". Included among them are Dawson College and John Abbott College. From babies to baby boomers, grandkids to grandparents, they filled parks and the lawns of legislatures and Parliament, toting papier-mache Earths and trees, some with full potted plants on their backs.
"I'm really frustrated at the inaction of our leaders", said Madeline Smith. "This is not only a flagrant disregard of science, but also of his responsibilities to future generations". "And that's not fun". In Toronto, thousands filled the front lawn of the provincial legislature and the streets around it. Over the past year, Greta Thunberg has arguably done more to galvanise global action on climate than any other single individual. "She is the face of new activism". Tens of thousands of students kicked things off in New Zealand.
"Honestly there's no point in saving for the future if we don't save the future", she said. After the meeting, the activist said that she told Trudeau he was not doing enough to respond to the climate crisis, though she clarified that it was the same message she conveys to all political leaders.
"I don't understand why grown-ups would choose to mock children and teenagers for just communicating and acting on the science when they could do something good instead", Thunberg said.
IPCC report: Fish haul could drop more than 20%
Smaller glaciers across the world are estimated to lose over 80 percent of the present ice bulk by 2100 if emissions are not cut. They could be happening at a rate 20 times higher with 2C of warming - or 50 times higher if emissions kept climbing.
Thunberg's message has been so effective because, in part, there's a reluctance to it that many of us can relate to.
The grassroots groups behind the Canadian marches have some specific demands, including refusing any new oil and gas projects and cutting emissions to be just one-quarter of what they were in 2005 by 2030. As the prime minister joined the Montreal march, police tackled another man who lunged at him to throw eggs.
Trudeau marched with some Quebec candidates, his wife, Sophie Gregoire Trudeau, and two of his three children, Xavier, 11, and Ella-Grace, 10. "To see the mobilization today, I'm very happy, but we have a lot more work to do".
One protester tried to throw an egg at Trudeau but was promptly wrestled to the ground by his security detail.
Video showed Trudeau consoling his son, who appeared to be frightened and was crying after the incident.
Lumley hoped the City of Lethbridge would lead the way for all citizens by adopting more electric vehicle usage among its crews, providing free public transit and by taking more steps to green up City infrastructure. City and commuter transport fees were waived in an effort to ease congestion. If you skipped the climate march, you looked very, very bad - but if you attended, as many sitting politicians did, you were protesting your own policies, thereby making you look like a fool.
