☆ How climate change could be driving ‘killer’ cold outbreaks in oceans
▼ + stars: | 2024-04-15 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +4 min

CNN —It’s not just ocean heat that’s affecting marine life – new research shows extremely cold events are welling up and causing mass mortalities. And the same planet-warming pollution that’s driving the climate crisis is likely to blame for these “killer events” on the other end of the temperature spectrum. The world’s oceans have been plagued by unprecedented heat over the past year, fueling concerns for marine life. “Climate change is actually really complex,” said Nicolas Lubitz, lead author of the study and a researcher at James Cook University in Queensland, Australia. He said seasonal upwelling events are common in that area, with water temperature dropping quickly.

CNN —The southern Great Barrier Reef is suffering from extensive coral bleaching due to heat stress, the reef’s managers said Wednesday, raising fears that a seventh mass bleaching event could be unfolding across the vast, ecologically important site. Jonas Gratzer/LightRocket/Getty ImagesThe Great Barrier Reef’s managers plan to extend aerial and in-water surveys across the entire reef over the coming weeks. Hotter ocean temperatures caused severe mass bleaching at the Great Barrier Reef in 2016, 2017 and 2020. Last year, the UNESCO World Heritage Committee decided not to add the Great Barrier Reef to its list of sites “in danger,” despite scientific evidence suggesting the risk of another mass bleaching event. Greenpeace’s Ritter said that following the decision, “the Australian government promised to do everything it can to protect the Great Barrier Reef.

CNN —A photo of a bright orange fungus growing on deadwood, with its striking color resplendent against the darkness, has been crowned winner of this year’s BMC Ecology and Evolution image competition. The image competition showcases the “intersection between art and science,” organizers said, in all its weird and wonderful forms. An image depicting an embryonic dinosaur developing within an egg between 72 million and 66 million years ago won the Paleoecology category. It was submitted by Jordan Mallon from the Candian Museum of Nature and created by Wenyu Ren from Beijing, China. A selection of the winning and runner-up images can be viewed in the gallery above.

☆ Great Barrier Reef stays off UNESCO ‘in danger’ list but hot El Niño summer looms

“A lot of climate scientists are shocked by the fact that it wasn’t put on the list,” Kimberley Reid from the ARC Centre of Excellence for Climate Extremes and Monash University told CNN. Covering nearly 133,000 square miles (345,000 square kilometers), the Great Barrier Reef is home to more than 1,500 species of fish and 411 species of hard corals. Environment minister Tanya Plibersek told reporters Tuesday she made no apology for lobbying UNESCO to keep the Great Barrier Reef off the “in danger” list. Bleaching events and global warming have done significant damage to the Great Barrier Reef. Tourists, divers and marine biologists enter and exit the waters of the Great Barrier Reef on August 10, 2022 on Hastings Reef, Australia.

☆ Canadian lake sediments reveal start of Earth's Anthropocene age, scientists say

Presence of plutonium and other evidence was found in core samples of the Crawford Lake sediments. The Anthropocene epoch is proposed as a chapter in Earth's history reflecting the transformation of the planet's climate and ecology as a result of human activity. The Anthropocene epoch has not yet been formally recognised by a scientific body called the International Commission on Stratigraphy. The scientists obtained core samples of sediment at Crawford Lake and sediments, soils, corals and ice samples at the other 11 sites. Crawford Lake sediments provided a record of accelerating changes that have unfolded in the past few decades, including traces of fly ash produced by burning fossil fuels.

☆ Our quest to make AI love us back is futile — and dangerous

But that's futile, experts say, because the AI of today can't feel empathy, let alone love. We've spent years trying to get AI to love us back. Experts told Insider that it's futile to expect the AIs that exist right now to love us back. During a simulation in October 2020, OpenAI's GPT-3 chatbot told a person asking for psychiatric help to kill themselves. Halpern, the UC Berkeley professor, told Insider AI-based relationships are perilous also because the entity can be used as a money-making tool.

☆ Australia argues against ‘endangered’ status for Great Barrier Reef

CANBERRA, Australia — Australia’s environment minister said Tuesday her government will lobby against UNESCO adding the Great Barrier Reef to a list of endangered World Heritage sites. The report, which recommended shifting the Great Barrier Reef to endangered status, followed a 10-day mission in March to the famed reef system off Australia’s northeast coast that was added to the World Heritage list in 1981. “We’ll very clearly make the point to UNESCO that there is no need to single the Great Barrier Reef out in this way” with an endangered listing, Plibersek told reporters. “If the Great Barrier Reef is in danger, then every coral reef in the world is in danger,” Plibersek said. The Great Barrier Reef accounts for around 10% of the world’s coral reef ecosystems.
