Australia's Land Surface Warmed by 1.5°C: BoM Report

Australia's Bureau of Meteorology (BoM) reveals a concerning trend: the land surface temperature in Australia has risen by 1.5°C since 1910. The annual climate statement by BoM indicates that 2023 ranked as Australia's joint-eighth warmest year on record, with temperatures 0.98°C above the average between 1961 and 1990.

Understanding the Figures: Implications and Clarifications

While global efforts aim to limit global heating to 1.5°C, it's crucial to note that this goal is relative to pre-industrial levels (1850-1900) and encompasses both land and ocean temperatures worldwide. The reported 1.5°C increase in Australia's land surface temperature, with a margin of error of ±0.23°C, solely accounts for land temperatures and doesn't align with the 1.5°C target.

Insights from Climate Experts

Dr. Simon Grainger, a senior climatologist at BoM, underscores the consistency between Australia's warming trend and global climate patterns. The warming trend, attributed mainly to fossil fuel combustion and land clearing, poses significant challenges.

Dr. Andrew King from the University of Melbourne emphasizes that Australia's land warming surpasses the global average, with the land warming faster than the oceans. Recent studies indicate that Australia's land surface has warmed at 1.4 times the global average since 1850-1900.

Impacts and Observations

The ramifications of rising temperatures extend beyond statistics. Dr. Linden Ashcroft, also from the University of Melbourne, stresses the significance of even fractional temperature increases, highlighting the alarming nature of hitting the 1.5°C milestone.

The effects of warming are palpable across Australia, with major cities experiencing record-breaking maximum temperatures. Sea surface temperatures have also risen, marking the seventh-warmest on record.

Looking Ahead: Climate Trends and Anomalies

Australia's climate in 2023 was characterized by extreme weather events, including the warmest winter on record and exceptionally dry periods. The transition from a fading La Niña to El Niño at the end of the year underscores the dynamic nature of climate patterns.

Conclusion: Urgency and Action

Australia's climate data serves as a clarion call for urgent action and heightened awareness. As climate change brings about pervasive impacts, addressing its causes and mitigating its effects become imperative.

Australia's climate journey underscores the interconnectedness of global climate systems and the need for concerted international efforts to combat climate change.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering MagR expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the MagR gene responded to magnetic fields only in the presence of light, with Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups. Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Start the New Year Humming Like a Bee

Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This was reported by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...

Why the Caraways are proud to “bee” farmers

Why the Caraways are proud to “bee” farmers Bees play a vital role in our ecosystem by spreading nutrients to crops, produce, and other plants. Ron and Diane Caraway are reminded of that each day on the homestead, Boggy Branch Farms, that’s been in their family for three generations. While Ron cared for the land as a teenager, he followed in his father’s footsteps and joined the U.S. Air Force after graduating high school. He managed airplanes for 45 years as an air traffic controller. Now, Ron manages flying insects as a beekeeper—or, as he puts it, a ‘bee partner.’ “They allow me to work alongside with them and to help them in some cases, with the case of parasites or diseases and I’m able to enjoy that fruit that they provide,” explained Ron. Along with raising their handful of hives, the Caraways grow hay and produce. Above all, they want to raise awareness for the bees’ essential role in making things grow. “One of the things that I think that we overlook is—in the Wiregrass ...

Climate Crisis Claims Glacier's Vital Climate Data Archive

Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

Watch bees defend their nest by slapping ants with their wings

Watch bees defend their nest by slapping ants with their wings With a flick of the wing, Japanese honeybees slap away ants that try to infiltrate their hive. Ants often invade honeybee nests, seeking to steal honey, prey on eggs or kill worker bees. In defence, bees have been known to fan their wings to blow ants away. Now, researchers have documented making contact with their wings and physically batting ants out of the hive, a behaviour that hasn’t been studied before. Footage from a high-speed camera shows that guard bees, positioned near a nest’s entrance, tilt their bodies towards approaching ants and flutter their wings while pivoting away. A successful hit sends the ant flying. Many beekeepers seem unaware of this strategy, says Yoshiko Sakamoto. “I myself did not notice this behavior during my approximately 10 years of beekeeping experience,” she says. Sakamoto, Yugo Seko and Kiyohito Morii, all at the National Institute for Environment...
