Several thousand scientists signed onto a letter Friday in support of youth climate activists who have demonstrated in favor of efforts to stop man-made climate change.

In a letter posted in Science magazine, more than 3,000 scientists called the battle to stop the Earth from warming due to carbon emissions a "social, ethical, and scholarly responsibility."

"Only if humanity acts quickly and resolutely can we limit global warming, halt the ongoing mass extinction of animal and plant species, and preserve the natural basis for the food supply and well-being of present and future generations," the scientists wrote. "This is what the young people want to achieve. They deserve our respect and full support."

The group went on to declare current efforts by the U.S. and other nations to battle carbon emissions "inadequate" for guaranteeing human survival on the planet.

"Their concerns are justified and supported by the best available science. The current measures for protecting the climate and biosphere are deeply inadequate," they wrote.

"Many social, technological, and nature-based solutions already exist," the letter continues. "The young protesters rightfully demand that these solutions be used to achieve a sustainable society. Without bold and focused action, their future is in critical danger. There is no time to wait until they are in power."

An international group of scientists led by the United Nations has warned that the globe has about a decade to rein in carbon emissions or risk the planet warming to uncontrollable levels.

In response, Swedish activist Greta Thunberg founded the Youth Strike for Climate, a worldwide movement that has led to thousands of students striking and refusing to attend school in an attempt to demand action on climate change.

Thunberg has since been nominated for a Nobel Prize, and has vowed to continue her movement until change is put in place.

"1659 places in 105 countries. And counting. Tomorrow we schoolstrike for our future," Thunberg tweeted last month. "And we will continue to do so for as long as it takes. Adults are more than welcome to join us. Unite behind the science."
