Today, the South Pole records average winter temperatures of 78 degrees Fahrenheit below zero. But roughly 90 million years ago, the fossils suggest, Antarctica was as warm as Italy and covered by a green expanse of rainforest.
Antarctica experienced unprecedented heat this summer, with a heatwave that began in late spring in the Antarctic Peninsula and circumnavigated the continent over the next four months. Since the late 19th century, the planet has warmed by roughly 0.8°C.
(CNN) The hottest temperature ever recorded in Antartica was measured on Thursday at a remote station on the continent’s Northern tip, scientists said. The temperature was nearly 65 degrees Fahrenheit (18.3 Celsius) at Argentina’s Esperanza research station, scientists from the country’s meteorological agency said.
Antarctica Was Once As Warm As Sunny California. Nearby polar regions got up to Florida-level temperatures. Modern-day Antarctica hardly brings beaches and sunshine to mind. But according to new research, the continent and its surroundings used to be a much balmier place.
How hot has Antarctica ever been?
The recent extraordinary heatwave in Antarctica appears to have set a new World Record for the largest temperature excess above normal (+38.5 °C / +69.3 °F) ever measured at an established weather station. It “appears to have set a new World Record for the largest temperature excess above normal …
When did Antarctica turn cold?
Antarctica hasn’t always been covered with ice – the continent lay over the south pole without freezing over for almost 100 million years. Then, about 34 million years ago, a dramatic shift in climate happened at the boundary between the Eocene and Oligocene epochs.
What was the climate of Antarctica before?
But according to new research, the continent and its surroundings used to be a much balmier place. During the Eocene, about 40 to 50 million years ago, Antarctica’s climate resembled the modern-day Californian coast, while nearby polar islands were more akin to Florida, Yale News reports.
Did Antarctica used to be Tropical?
For most of the past 100 million years, the south pole was a tropical paradise, it transpires. “It was a green beautiful place,” said Prof Jane Francis, of Leeds University’s School of Earth and Environment. “Lots of furry mammals including possums and beavers lived there. The weather was tropical.
What caused Antarctica to freeze over?
The prime suspect is a gradual reduction of CO2 in the atmosphere, combined with a ’trigger’ time when Earth’s orbit around the sun made Antarctic summers cold enough for ice to remain frozen all year round.
What froze Antarctica?
The glaciers carved out valleys that had already been worn in by river flow, changing the topography. Once the expansive ice sheets that now cover the continent began to form, they preserved these landforms in frigid perpetuity.
How did Antarctica get icy?
A new paper reveals that the frozen continent of Antarctica was once a temperate rainforest. This dramatic difference in climate was due to high levels of CO2 that managed to maintain mild weather even through months when the sun didn’t shine on this part of the world.
What was Antarctica like before it froze?
A new paper reveals that the frozen continent of Antarctica was once a temperate rainforest. This dramatic difference in climate was due to high levels of CO2 that managed to maintain mild weather even through months when the sun didn’t shine on this part of the world.
What is underneath Antarctica ice?
Antarctica is hiding a huge amount of water beneath its surface. Researchers have long suspected that there might be groundwater buried beneath the ice, but until now there has been no conclusive evidence to confirm that suspicion.
What was Antarctica like before humans?
Antarctica was once abundant plant and animal life. There has been life on Earth for about 3.5 billion years. Until about 575 million years ago, all life was microscopic plant life. Antarctica used to be part of the supercontinent Gondwana.
Was Antarctica once green?
Before the start of the Eocene Epoch about 56 million years ago, Antarctica was still joined to both Australia and South America. During this time, Antartica was without ice and snow. Fossil records indicate it was covered in green foliage. Part of the “Eons” series.
Did anybody ever live in Antarctica?
But do people live in Antarctica now? Although there are no native Antarcticans and no permanent residents or citizens of Antarctica, many people do live in Antarctica each year.

Weather fronts rarely penetrate far into the continent, because of the katabatic winds.
