"[C]limate change is just a very, very expensive form of tax."

"I believe in climate change caused by human beings. What I'm skeptical about is the glib notion that it means the end of the world as we know it."

"The clock is no longer just ticking, it is banging."

"There is no long-term prosperity without action on climate change."

"The time for seeking global solutions [to climate change] is running out."

"The climate crisis is the existential threat. That's not hyperbole; it's a fact."

"[W]e are killing our planet."

Climate change is "above all, an existential crisis."

"Climate change is one of the greatest challenges mankind faces."

"If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon."

"Humanity is on thin ice — and that ice is melting fast."

"We haven't yet exceeded the bounds of viable human civilisation, but we're getting close."

Is Climate Change an Existential Threat?

While these changes are concerning, they highlight the need for better scientific understanding rather than panic. Current climate models clearly need updating based on new satellite data. The focus should be on improving monitoring capabilities and research funding to accurately predict future changes in this complex system.
