A striking new visualization looks like a flower blooming but tells an alarming story about what's happening to the planet
A striking new visualization made by climate scientist Zeke Hausfather unfurls like a flower blooming in the spring, its colors moving from blue to red. It may look beautiful but what it reveals is an alarming picture of a heating planet.
The graphic shows the increase in daily global temperatures between 1940 and the end of 2024 compared to the period before humans began burning huge amounts of planet-heating fossil fuels.
It paints a stark picture. As the data spirals outwards, it becomes redder and redder as global temperatures ramp up.
Good visualizations can make climate change 'more visceral and understandable,' said Hausfather, the climate research lead at Stripe and a research scientist at Berkeley Earth.
Charting the evolution of global temperatures over the past 85 years makes it 'crystal clear how rapidly the planet has warmed over the past few decades, and how worryingly hot both 2023 and 2024 were compared to any prior years,' he told CNN.
Last year was the hottest year in recorded history, breaking a record set just the year before. It was also the first calendar year to breach 1.5 degrees Celsius above pre-industrial levels, a critical climate threshold.
Scientists have been struggling to fully explain the extraordinary heat of the past few years. While it has been driven predominantly by burning fossil fuels and the natural climate pattern El Niño, these factors alone don't entirely explain the unusually rapid temperature rise.
What scientists are clear on, however, is that every fraction of a degree the world warms, the worse the effects will be for humans and ecosystems, including more frequent and severe fires, storms and floods.
'Global warming has accelerated in recent years and poses a major threat to our livelihood and to the natural world if we do not take action to reduce emissions,' Hausfather said.

EPA says power plant carbon emissions aren't dangerous. We asked 30 scientists: Here's what they say
WASHINGTON (AP) — The Trump administration's Environmental Protection Agency on Wednesday proposed a new ruling that heat-trapping carbon gas 'emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution.'' The Associated Press asked 30 different scientists, experts in climate, health and economics, about the scientific reality behind this proposal. Nineteen of them responded, all saying that the proposal was scientifically wrong and many of them called it disinformation. Here's what eight of them said. 'This is the scientific equivalent to saying that smoking doesn't cause lung cancer,' said climate scientist Zeke Hausfather of the tech firm Stripe and the temperature monitoring group Berkeley Earth. 'The relationship between CO2 emissions and global temperatures has been well established since the late 1800s, and coal burning is the single biggest driver of global CO2 emissions, followed by oil and gas. It is utterly nonsensical to say that carbon emissions from power plants do not contribute significantly to climate change.' 'It's about as valid as saying that arsenic is not a dangerous substance to consume,' said University of Pennsylvania climate scientist Michael Mann. 'The world is round, the sun rises in the east, coal-and gas-fired power plants contribute significantly to climate change, and climate change increases the risk of heat waves, catastrophic storms, infectious diseases, and many other health threats. These are indisputable facts,' said Dr. Howard Frumkin, former director of the National Center for Environmental Health and a retired public health professor at the University of Washington. Climate economist R. Daniel Bressler of Columbia University, said: 'We can use tools from climate economics, including the mortality cost of carbon and the social cost of carbon, to estimate the climate impacts of these emissions. For instance, in my past work, I found that adding just one year's worth of emissions from an average-sized coal-fired plant in the U.S. causes 904 expected temperature-related deaths and over $1 billion in total climate damages.' University of Arizona climate scientist Kathy Jacobs said: 'Their statement is in direct conflict with evidence that has been presented by thousands of scientists from almost 200 countries for decades. 'It's basic chemistry that burning coal and natural gas releases carbon dioxide and it's basic physics that CO2 warms the planet. We've known these simple facts since the mid-19th century,' said Oregon State's Phil Mote. Andrew Weaver, a professor at the University of Victoria and former member of parliament in British Columbia, said: 'President Trump is setting himself up for international court charges against him for crimes against humanity. To proclaim you don't want to deal with climate change is one thing, but denying the basic science can only be taken as a wanton betrayal of future generations for which there should be consequences.' Stanford climate scientist Chris Field, who coordinated an international report linking climate change to increasingly deadly extreme weather, summed it up this way: 'It is hard to imagine a decision dumber than putting the short-term interests of oil and gas companies ahead of the long-term inters of our children and grandchildren.' ___ Matthew Daly and Michael Phillis contributed from Washington.

A ‘dragon prince' dinosaur is redrawing the tyrannosaur family tree
Sign up for CNN's Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. Scientists have identified a previously unknown 86 million-year-old dinosaur species that fills an early gap in the fossil record of tyrannosaurs, revealing how they evolved to become massive apex predators. Researchers analyzing the species' remains have named it Khankhuuluu mongoliensis, which translates to 'dragon prince of Mongolia,' because it was small compared with its much larger relatives such as Tyrannosaurus rex, whose name means 'the tyrant lizard king.' The newly identified dinosaur was the closest known ancestor of tyrannosaurs and likely served as a transitional species from earlier tyrannosauroid species, according to the findings published Wednesday in the journal Nature. Based on a reexamination of two partial skeletons uncovered in Mongolia's Gobi Desert in 1972 and 1973, the new study suggests that three big migrations between Asia and North America led tyrannosauroids to diversify and eventually reach a gargantuan size in the late Cretaceous Period before going extinct 66 million years ago. 'This discovery of Khankhuuluu forced us to look at the tyrannosaur family tree in a very different light,' said study coauthor Darla Zelenitsky, associate professor within the department of Earth, energy, and environment at the University of Calgary, in an email. 'Before this, there was a lot of confusion about who was related to who when it came to tyrannosaur species. What started as the discovery of a new species ended up with us rewriting the family history of tyrannosaurs.' Tyrannosaurs, known scientifically as Eutyrannosaurians, bring to mind hulking dinosaurs like Tyrannosaurus rex and Tarbosaurus, which weighed multiple metric tons and could take down equally large prey. With short arms and massive heads, they walked on two legs and boasted sharp teeth, Zelenitsky said. But tyrannosaurs didn't start out that way. They evolved from smaller dinosaurs before dominating the landscapes of North America and Asia between 85 million and 66 million years ago, the researchers said. While Tarbosaurus, an ancestor of T. rex, clocked in at between 3,000 and 6,000 kilograms (6,613 pounds and 13,227 pounds), the fleet-footed Khankhuuluu mongoliensis likely weighed only around 750 kilograms (1,653 pounds), spanned just 2 meters (6.5 feet) at the hips and 4 meters (13 feet) in length, according to the study authors. Comparing the two dinosaurs would be like putting a horse next to an elephant —Khankhuuluu would have reached T. rex's thigh in height, Zelenitsky said. 'Khankhuuluu was almost a tyrannosaur, but not quite,' Zelenitsky said. 'The snout bone was hollow rather than solid, and the bones around the eye didn't have all the horns and bumps seen in T. rex or other tyrannosaurs.' Khankhuuluu mongoliensis, or a closely related ancestor species, likely migrated from Asia to North America across a land bridge between Alaska and Siberia that connected the continents 85 million years ago, Zelenitsky said. Because of this migrant species, we now know that tyrannosaurs actually evolved first on the North American continent and remained there exclusively over the next several million years, she said. 'As the many tyrannosaur species evolved on the continent, they became larger and larger.' Due to the poor fossil record, it's unclear what transpired in Asia between 80 million to 85 million years ago, she added. While some Khankhuuluu may have remained in Asia, they were likely replaced later on by larger tyrannosaurs 79 million years ago. Meanwhile, another tyrannosaur species crossed the land bridge back to Asia 78 million years ago, resulting in the evolution of two related but very different subgroups of tyrannosaurs, Zelenitsky said. One was a gigantic, deep-snouted species, while the other known as Alioramins was slender and small. These smaller dinosaurs have been dubbed 'Pinocchio rexes' for their long, shallow snouts. Both types of tyrannosaurs were able to live in Asia and not compete with each other because the larger dinosaurs were top predators, while Alioramins were mid-level predators going after smaller prey — think cheetahs or jackals in African ecosystems today, Zelenitsky said. 'Because of their small size, Alioramins were long thought to be primitive tyrannosaurs, but we novelly show Alioramins uniquely evolved smallness as they had 'miniaturized' their bodies within a part of the tyrannosaur family tree that were all otherwise giants,' Zelenitsky said. One more migration happened as tyrannosaurs continued to evolve, and a gigantic tyrannosaur species crossed back into North America 68 million years ago, resulting in Tyrannosaurus rex, Zelenitsky said. 'The success and diversity of tyrannosaurs is thanks to a few migrations between the two continents, starting with Khankhuuluu,' she said. 'Tyrannosaurs were in the right place at the right time. They were able to take advantage of moving between continents, likely encountering open niche spaces, and quickly evolving to become large, efficient killing machines.' The new findings support previous research suggesting that Tyrannosaurus rex's direct ancestor originated in Asia and migrated to North America via a land bridge and underscore the importance of Asia in the evolutionary success of the tyrannosaur family, said Cassius Morrison, a doctoral student of paleontology at University College London. Morrison was not involved in the new research. 'The new species provides essential data and information in part of the family tree with few species, helping us to understand the evolutionary transition of tyrannosaurs from small/ medium predators to large apex predators,' Morrison wrote in an email. The study also shows that the Alioramini group, once considered distant relatives, were very close cousins of T. rex. What makes the fossils of the new species so crucial is their age — 20 million years older than T. rex, said Steve Brusatte, professor and personal chair of Palaeontology and Evolution at the University of Edinburgh. Brusatte was not involved in the new study. 'There are so few fossils from this time, and that is why these scientists describe it as 'murky,'' Brusatte said. 'It has been a frustrating gap in the record, like if you suspected something really important happened in your family history at a certain time, like a marriage that started a new branch of the family or immigration to a new country, but you had no records to document it. The tyrannosaur family tree was shaped by migration, just like so many of our human families.' With only fragments of fossils available, it's been difficult to understand the variation of tyrannosaurs as they evolved, said Thomas Carr, associate professor of biology at Carthage College in Wisconsin and director of the Carthage Institute of Paleontology. Carr was not involved in the new research. But the new study sheds light on the dinosaurs' diversity and clarifies which ones existed when — and how they overlapped with one another, he said. More samples from the fossil record will provide additional clarity, but the new work illustrates the importance of reexamining fossils collected earlier. 'We know so much more about tyrannosaurs now,' Carr said. 'A lot of these historical specimens are definitely worth their weight in gold for a second look.' When the fossils were collected half a century ago, they were only briefly described at the time, Brusatte said. 'So many of us in the paleontology community knew that these Mongolian fossils were lurking in museum drawers, waiting to be studied properly, and apt to tell their own important part of the tyrannosaur story,' he said. 'It's almost like there was a non-disclosure agreement surrounding these fossils, and it's now expired, and they can come out and tell their story.'
