RE:RE:RE:RE:climate"graph of earth's temperature over centuries. "
Yes, the article you cited does in fact have a graph, but there are also several paragraphs written that explain what you are seeing that I don’t believe you bothered to read.
“The timeline illustrates how swift and dramatic temperature shifts were associated with many of the world’s worst moments — including a mass extinction that wiped out roughly 90 percent of all species and the asteroid strike that killed the dinosaurs.”
“We know that these catastrophic events … shift the landscape of what life looks like,” Judd said.
“When the environment warms that fast, animals and plants can’t keep pace with it.”
At no point in the nearly half-billion years that Judd and her colleagues analyzed did the Earth change as fast as it is changing now, she added:
“…in keeping with decades of past research on climate, the chart hews closely to estimates of carbon dioxide in the atmosphere, with temperatures rising in proportion to concentrations of the heat-trapping gas.
"An even more dramatic shift occurred at the end of the Permian period, about 251 million years ago. Massive volcanic eruptions unleashed billions of tons of carbon dioxide into the atmosphere, causing the planet’s temperature to shoot up by about 18 F (10 C) in roughly 50,000 years. Acid rain fell across the continents; marine ecosystems collapsed as the oceans became boiling hot and depleted of oxygen."
“We know it to be the worst extinction in the Phanerozoic,” Tierney said. “By analogy, we should be worried about human warming because it’s so fast. We’re changing Earth’s temperature at a rate that exceeds anything we know about.”
“…humans evolved during the coldest epoch of the Phanerozoic, when global average temperatures were as low as 51.8 F (11 C).”
Lastly if you bothered to read the whole article you would have learned -
“And for the billions of people who are now living through the hottest years ever recorded — and facing a hotter future still — Judd said the timeline should serve as a wake-up call. Even under the worst-case scenarios, human-caused warming will not push the Earth beyond the bounds of habitability. But it will create conditions unlike anything seen in the 300,000 years our species has existed — conditions that could wreak havoc through ecosystems and communities.
“My concern is what human life looks like. What it means to survive.”
What is your concern?
