(Press-News.org) WASHINGTON, Oct. 17, 2023 – Climate change and the rapid increase in frequency of extreme weather events around the globe – such as wildfires and floods – reinforces the reality that these events are not only not random but, rather, interconnected. Interlinked climate behavior, or teleconnections, isn’t a well understood field but will be necessary to fully comprehend how our climate system works.
In Chaos, from AIP Publishing, a team of researchers affiliated with Beijing Normal University and Beijing University of Posts and Telecommunications in China and the Potsdam Institute for Climate Impact Research in Germany describes a climate network analysis method to explore the intensity, distribution, and evolution of teleconnections.
“Teleconnections describe how climate events in one part of the world can affect weather thousands of kilometers away,” said co-author Jingfang Fan of Beijing Normal University and the Potsdam Institute for Climate Impact Research. “Think of it as a domino effect on a global scale.”
And then there’s global warming – the Earth is becoming hotter. “Within just five years, we may see temperatures rising to levels that global scientists have been warning us about,” said Fan. “It’s like the planet is running a fever that’s steadily getting worse.”
Climate networks are akin to maps where data points are marked as locations, and the connections between them reveal similarities.
The researchers’ climate network analysis method combines the directions and distribution patterns of teleconnections to evaluate their intensity and to identify sensitive regions using global daily surface air temperature data. Their method relies on advanced data processing and mathematical algorithms to find meaningful insights.
“Our work uncovered patterns in climate events driven mainly by atmospheric Rossby waves, which are large inertial planetary waves that naturally occur in rotating fluids and cause movement within the atmosphere,” said Fan.
The team identified areas significantly affected by these interconnected events, within regions like southeastern Australia and South Africa, which are particularly sensitive. One fascinating discovery they made is that these interconnections are becoming stronger over time, from 1948 to 2021, possibly due to a mix of climate change, human activities, and other factors. The extent and intensity of the impact of teleconnections has increased more prominently in the Southern Hemisphere during the past 37 years.
This work provides a new way to measure and explore climate teleconnections. The researchers plan to use this knowledge to pinpoint which regions may be at a higher risk in the future and to devise strategies to address these challenges.
“The next step is like weather forecasting – but on steroids,” said Fan. “Using what we’ve learned, we plan to predict how climate events will unfold and connect. We’re diving deep to explore why these events happen and how various climate ‘tipping points’ within our climate system might be linked.”

AI models identify biodiversity from animal sounds in tropical rainforests
2023-10-17
Tropical forests are among the most important habitats on our planet. They are characterised by extremely high species diversity and play an eminent role in the global carbon cycle and the world climate. However, many tropical forest areas have been deforested and overexploitation continues day by day.
Reforested areas in the tropics are therefore becoming increasingly important for the climate and biodiversity. How well biodiversity develops on such areas can be monitored very well with an automated analysis of animal sounds. This was reported by researchers in the journal Nature Communications.

Recognizing clinical signs of hyperthyroidism leads to appropriate treatments, reduces adverse impact on health
2023-10-17
(Boston)—Untreated hyperthyroidism, conditions where there is excess thyroid hormone present, can adversely affect health, leading to increased risks for abnormal heart rhythms, heart failure, osteoporosis, adverse pregnancy outcomes, metabolic abnormalities and increased mortality risk. Hyperthyroidism can occur due to several different etiologies, including Graves’ disease, toxic (overactive) thyroid nodules, and thyroiditis. It is important to recognize, correctly diagnose, and appropriately treat the underlying cause of hyperthyroidism to minimize its impacts on health.

Adults with ADHD are at increased risk for developing dementia
2023-10-17
Adults with attention-deficit/hyperactivity disorder (ADHD) are nearly three times more likely to develop dementia than adults without ADHD, according to a Rutgers study.
The study, coauthored by Michal Schnaider Beeri, director of the Herbert and Jacqueline Krieger Klein Alzheimer’s Research Center at Rutgers Brain Health Institute (BHI) was published in JAMA Network Open. It followed more than 100,000 older adults in Israel over 17 years to examine if adults with ADHD are at increased risk for dementia, including Alzheimer’s disease.
Although more than 3 percent of the adult population in the United States has ADHD, there is limited research ...
Orchid without bumblebee on island finds wasp, loses self
2023-10-17
Because the bumblebee that an orchid relies on for pollination does not exist on a remote island, the plant gets pollinated by an island wasp. Kobe University researchers found that this came at the cost of being hybridized with another orchid species adapted to being pollinated by the wasp. The finding showcases how plants in ecological relationships adapt to changing circumstances.
Remote islands have been exciting study grounds for biologists since at least the days of Darwin. When studying ecological relationships between different species, the differences between mainland and island ...
Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
2023-10-17
Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Numerous studies have shown that global microplastic quantities in the marine environment are increasing, even in remote locations such as the Arctic.
The Barents Sea, which adjoins the Arctic Ocean, is one of the most productive oceanic areas in the world and home to an enormous diversity of organisms.
It is also a key route for Atlantic ...
Boosting weak immune system: scientists find an unusual weapon against virus
2023-10-17
Some viruses can be dormant throughout a person’s life and cause no harm but become dangerous when the immune system is weakened. One of such viruses is human cytomegalovirus (CMV). Harmless to the general public but life-threatening to patients with a supressed immune system.
“Patients undergoing bone marrow transplantations have their blood and immune system fully replaced by that of the donor. In the first months after transplantation they are defenseless. They can either catch CMV or have virus reactivated that was dormant in the patient. At the moment, there is no ideal treatment. The available ones work ...
Depression, anxiety common among college students
2023-10-17
Depression and anxiety among college students is a growing public health problem. And new research from the University of Georgia suggests the problem may be worse for students who aren’t the same race as most of their peers.
The new study found that students who were not the majority race at a predominantly white college reported significantly higher rates of depression than their white peers.
At the mostly white university, more than half of the students who self-identified as races other than white reported feelings of mild depression. An additional 17% said they were experiencing moderate to severe depression.
Students at the predominantly ...
Research finds water quality in Gulf of Mexico improves when adding social costs to carbon emissions
2023-10-17
DURHAM, N.H.—U.S. Climate policies can offer options for putting climate change efforts into place that solve environmental problems like excessive carbon dioxide in the atmosphere created by greenhouse gas emissions. Research led by the University of New Hampshire took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline by as much as 50%, the cost of fertilizer would rise leading to a significant benefit on water quality by lessening fertilizer runoff contributing ...
