11 months on trot of world’s record-breaking temperatures

May 9, 2024355 Views

The world just experienced its hottest April on record, extending an 11-month streak in which every month set a temperature record, the European Union's climate change monitoring service said on Wednesday. Each month since June 2023 has ranked as the planet's hottest on record, compared with the corresponding month in previous years, the Copernicus Climate Change Service (C3S) said in a monthly bulletin.

Nearly half of China’s major cities are sinking — some ‘rapidly’

Tens of millions of people in the country’s coastal lands might find their homes below sea level by 2120 owing to sinking and sea-level rise One in ten residents of China’s coastal cities could be living below sea level within a century, as a result of land subsidence and climate change, according to a paper published in Science. Some 16% of the mapped area of China’s major cities is sinking “rapidly” — faster than 10 millimetres every year. An even greater area, roughly 45%, is sinking at a “moderate” rate, the paper says, meaning a downward trajectory of greater than 3 mm annually. Affected cities include the capital Beijing, as well as regional capitals, including Fuzhou, Hefei and Xi’an. The situation could see one-quarter of China’s coastal lands slip below sea level within ...

Coral reefs around the world are experiencing mass bleaching in warming oceans

Huge stretches of coral reef around the world are turning a ghostly white this year amid record warm ocean temperatures. Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared Monday, a result of warming ocean waters amid human-caused climate change. On Monday, the U.S. National Oceanic and Atmospheric Administration confirmed the world's fourth mass global bleaching event is underway - with serious consequences for marine life and for the people and economies that rely on reefs. Coral reef bleaching across at least 53 countries, territories or local economies has been confirmed from February 2023 to now, scientists from the National Oceanic and Atmospheric Administration and International Coral Reef Initiative said. It ...

The world just experienced its warmest March on record, capping a 10-month streak in which every month set a new temperature record, the European Union's climate change monitoring service said on Tuesday. Each of the last 10 months ranked as the world's hottest on record, compared with the corresponding month in previous years, the EU's Copernicus Climate Change Service (C3S) said in a monthly bulletin. The 12 months ending with March also ranked as the planet's hottest ever recorded 12-month period, C3S said. From April 2023 to March 2024, the global average temperature was 1.58 degrees Celsius above the average in the 1850-1900 pre-industrial period.

Climate change has slowed Earth’s rotation — and could affect how we keep time

The effect of melting polar ice could delay the need for a ‘leap second’ by three years Climate change is starting to alter how humans keep time. An analysis published in Nature on 27 March has predicted that melting ice caps are slowing Earth’s rotation to such an extent that the next leap second — the mechanism used since 1972 to reconcile official time from atomic clocks with that based on Earth’s unstable speed of rotation — will be delayed by three years. “Enough ice has melted to move sea level enough that we can actually see the rate of the Earth’s rotation has been affected,” says Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography in La Jolla, California, and author of the study.

Australian scientists find coral bleaching in Great Barrier Reef’s far north

March 15, 2024547 Views

Australian researchers have found coral bleaching around six islands in the far northern parts of the Great Barrier Reef, after a government agency said last week a major bleaching event was unfolding across the world's most extensive reef ecosystem. Scientists at the James Cook University said on Friday they found only a few relatively healthy areas, mostly in deeper waters, after surveying sites at the Turtle Group National Park, about 10 km (6.2 miles) offshore the state of Queensland. "It was quite devastating to see just how much bleaching there was, particularly in the shallows ... (but) they were all still at the stage of bleaching where they could still recover as long as the water temperatures decline in time," lead researcher Maya Srinivasan told Reuters. Bleaching ...

Norway gives Arctic foxes a helping hand amid climate woes

One by one, the crate doors swing open and five Arctic foxes bound off into the snowy landscape. In the wilds of southern Norway, the newly freed foxes could struggle to find enough to eat, as the impacts of climate change make the foxes’ traditional rodent prey more scarce. In Hardangervidda National Park, where the foxes have been released, there hasn’t been a good lemming year since 2021, scientists say. That’s why the scientists breeding them in captivity are also maintaining more than 30 feeding stations across the alpine wilderness stocked with dog food kibble – a rare and controversial step in conservation circles.

Spring came early: February likely warmest on record amid climate change

The world likely notched its warmest February on record, as spring-like conditions caused flowers to bloom early from Japan to Mexico, left ski slopes bald of snow in Europe and pushed temperatures to 100 degrees Fahrenheit (38 C) in Texas. While data has not been finalised, three scientists told Reuters that February is on track to have the highest global average temperature ever recorded for that month, thanks to climate change and the warming in the Eastern Pacific Ocean known as El Nino.

Some U.S. residents will be going from wearing Bermuda shorts to snow pants in less than 24 hours, forecasters said on Monday, as a heat wave in the central Plains and South gives way to weather more typical for this time of year. Temperatures on Monday in states like Nebraska and Iowa were in the mid-70s Fahrenheit (low 20s Celsius), some 40 degrees F (22 degrees C) above averages for this time of year, while cities in the South, such as Dallas, Texas, sizzled in the mid-90s F (mid-30s C).

Early jacaranda bloom sparks debate about climate change

Every spring, the streets of Mexico's capital are painted purple with the flowering of thousands of jacaranda trees. Their spectacular colors not only attract the eyes of residents and tourists, but also birds, bees and butterflies that find food and shelter in them. But this year something changed. Some jacarandas began blooming in early January, when they normally awaken in spring. The early onset bloom has set off alarm bells among residents and scientists in Mexico City, where the trees have become an iconic, photogenic mainstay of city streets. Local scientists have begun investigating how widespread the early-bloom phenomenon is, but they point to climate change as the first culprit. People walk near a jacaranda tree at Plaza Cibeles in Mexico City, Mexico. February 22, ...
