Extreme Heat Waves: A Climate Crisis Unfolding

The sweltering heat wave of June 2024 left over 100 million Americans grappling with soaring temperatures, particularly in the eastern U.S. This sudden and extreme event led to flash drought warnings, threatening agriculture, water supplies, and energy resources. The National Oceanic and Atmospheric Administration (NOAA) highlighted these risks, showing how rapidly dry conditions developed under the intense heat.

Human Impact: A Rising Toll

The human cost was significant. In Ohio and Pennsylvania, emergency rooms saw a spike in heat-related illnesses. Schools in Massachusetts, lacking air conditioning, closed to safeguard students and staff. In the New York-New Jersey area, sagging electric wires caused train shutdowns, stranding commuters.

Our research into weather patterns reveals that the June 2024 heat wave was unusually early and prolonged. A massive high-pressure system, or heat dome, reaching unprecedented atmospheric heights, was responsible. This heat dome was both a symptom and a driver of extreme heat, with the potential to affect millions.

Global Heat Wave Crisis

This wasn’t an isolated incident. Record heat waves struck across the Americas, Europe, and Asia. Mexico and Central America faced weeks of relentless heat and drought, leading to severe water shortages and fatalities. In Saudi Arabia, over 1,000 Hajj pilgrims succumbed to the extreme temperatures. Greece and India also experienced deadly heat, impacting countless lives.

The Climate Connection

While heat waves are natural, the severity and frequency seen today are not. Human-induced climate change has made such events two to four times more likely. Our climate is now 2.2 F (1.2 C) warmer than pre-industrial times, a change driven by greenhouse gas emissions.

Looking Forward: Solutions and Actions

Despite the daunting outlook, there is hope. Policies like the U.S. Inflation Reduction Act aim to halve greenhouse gas emissions by 2035. Transitioning to renewable energy sources and adopting technologies like heat pumps can reduce emissions and lower cooling costs.

Immediate action to curb fossil fuel use can prevent worse heat waves, improve public health, and create economic opportunities. It's imperative for nations, companies, and individuals to act decisively.

The June 2024 heat wave affected over 100 million people in the eastern U.S., causing rapid-onset droughts, agricultural issues, and power disruptions. The heat wave was caused by a large high-pressure system known as a heat dome, which extended higher into the atmosphere than previous events. This phenomenon was part of a global pattern of early-season heat affecting various countries, leading to severe health and infrastructure impacts.

Heat waves, exacerbated by climate change, are now more frequent and intense. Global temperatures have risen by 2.2 F (1.2 C) since the industrial revolution, primarily due to greenhouse gas emissions. Despite international efforts like the Paris Agreement, current policies are insufficient to meet climate targets, and temperatures are expected to continue rising.

Solutions to mitigate future warming include reducing fossil fuel emissions, adopting renewable energy, and implementing policies like the U.S. Inflation Reduction Act. These measures can reduce the frequency of extreme heat events and offer additional benefits such as improved public health and economic opportunities.

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...

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.

“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...

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 Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts. Without bees, a large portion of the food we eat would not be available. Q2: What are the main threats to...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

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...

German election: Climate and environment take a back seat

German election: Climate and environment take a back seat When the coalition government comprising the center-left Social Democratic Party (SPD) , Greens and neoliberal Free Democratic Party (FDP) emerged after the last German federal election in the fall of 2021, then-incoming Chancellor Olaf Scholz (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor Robert Habeck from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right Christian Democratic Union (CDU) , Friedrich Merz ...
