Collapse of the Atlantic Meridional Overturning Circulation in a Strongly Eddying Ocean‐Only Model A 600 years quasi-equilibrium freshwater hosing simulation was performed using a strongly-eddying version of an ocean-only model At a hosing strength of about 0.125 Sv, the Atlantic Meridional Ov...

Model simulations demonstrate that the AMOC has a tipping point, with some future #climatechange scenarios predicting its shutdown within decades.

RealClimate: High-resolution ‘fingerprint’ images reveal a weakening Atlantic Ocean circulation (AMOC) RealClimate: The #AMOC is the reason for Europe’s mild climate. Evidence that it is slowing has been piling up over the years – it now is likely at its weakest in at least a millennium, and it may eve...

Meteorologists attribute the unpredictable weather to the interaction between the monsoon and westerly disturbances, low-pressure systems originating from the Mediterranean region, which are arriving earlier and more frequently.

How the autumn climbing season turned deadly in the Himalayas Unpredictable, intense and longer monsoons are encroaching into autumn, turning it into a deadly season.

The autumn climbing season in the Himalayas is becoming increasingly deadly due to climate change's effect on weather patterns, as the monsoon season now extends into October.

Alzheimer’s disease signatures in the brain transcriptome of Estuarine Dolphins - Communications Biology Transcriptomic analysis of brain samples collected from dolphins found beached in the Indian River Lagoon during algal bloom seasons shows Alzheimer’s disease related molecular signatures.

Researchers found that 2,4-DAB concentrations in dolphin brains were 2900 times higher during bloom seasons with impairments in GABAergic synapses, basement membrane alteration, and increased Alzheimer's disease risk factors.

Scientists Think Climate Change Is Causing Alzheimer’s-Like Brain Damage in Dolphins Well, here’s a bummer of a story: dolphins are getting Alzheimer’s, and climate change might be the one driving them senile.

Increasing toxic algae blooms due to #climatechange caused warming oceans and nutrient-rich runoff is causing higher levels of 2,4-diaminobutyric acid in to accumulate in the brains of dolphins. A study found the this is causing Alzheimer's-like symptoms in the mammals.

The moratorium is based on the 1980 Arizona Groundwater Management Act and has sparked debate.
The situation is exacerbated by the worst drought in the Southwest in at least 1,200 years and a nationwide housing crisis.

The dried-out subdivisions of Phoenix - High Country News A groundwater crisis halted the construction of thousands of homes and pitted affordability against environmental concerns.

The #Phoenix metro area faces a housing crisis due to a moratorium on new groundwater-based subdivisions, impacting nearly half a million homes.

The shift was driven by renewable energy growth in major economies like India and China, while the US and EU saw increased reliance on fossil fuels due to rising energy demand and unfavorable weather conditions affecting hydropower.

Renewables overtake coal in global electricity generation – DW – 10/07/2025 In the first half of 2025, more electricity was generated from green sources than from coal. Solar and wind capacities are growing at a faster pace than global electricity demand, according to new res...

Renewable energy sources surpassed coal as the primary source of global electricity generation for the first time in the first half of this year, according to a study by Ember, a global energy think tank.

Risky Summer 2025 Heat Added by Climate Change | Climate Central New analysis shows that carbon pollution drove risky heat across the globe and in the U.S. this summer.

In the U.S., 193 cities experienced 7 or more days with temperatures significantly elevated by climate change, and over 21 million people faced at least 30 days of risky heat (defined as those days hotter than 90% of local temperatures recorded between 1991 and 2020) driven by carbon pollution.

New report shows that climate change added more hot days to the summer A new scientific report shows that the number of days considered a heat risk this summer have risen across the U.S., including in northern Nevada.

A report by Climate Central found that #climatechange has greatly increased the number of hot days in many U.S. cities during the summer.

In Reno, Nevada, of the 37 days that were hotter than average, 25 were a result of climate change.

Also, a significant portion of U.S. retirement wealth is tied to climate-exposed assets, including fossil fuel investments, which are both exacerbating the climate crisis and likely to lose their value in a sustainable future.

Climate Change Puts A Generation’s Retirement On The Line Early retirement withdrawals for hardship have tripled since 2020, as disasters strike and insurance fails–leaving workers on their own in old age.

Climate change is increasingly jeopardizing retirement security for many Americans, with natural disasters destroying homes and driving hardship withdrawals to 401K savings.

Glacier preservation doubled by limiting warming to 1.5°C versus 2.7°C Glaciers adapt slowly to changing climatic conditions, with long-term implications for sea-level rise and water supply. Using eight glacier models, we simulated global glacier evolution over multicent...

Half of the ice remaining across the world's mountain glaciers could be preserved if global warming is limited to 1.5C above "pre-industrial" levels of the late 1800s, according to research published this year in the journal Science.

Before and after images show glaciers vanishing before our eyes They are melting like never seen before, changing landscapes around the world beyond recognition.

The 2024 World Meteorological Organization report shows that glaciers outside of Greenland and Antarctica lost 450 billion tonnes of ice. That's equivalent to a block of ice 7km (4.3 miles) tall, 7km wide and 7km deep.

Marine heat waves are becoming more common, and coral reefs are among the most vulnerable ecosystems in the world to climate change. Studies show that if climate change stays on the current path, surpassing 3.6 degrees Fahrenheit (2 degrees Celsius) by 2100, 99% of the world's coral will be lost.

Why scientists are using corals from other countries to help save Florida's reefs The past three summers have been the worst on record for Florida's coral reefs. To try to restore them, scientists are breeding corals that can handle heat better, using coral from other countries.

The University of Miami is crossbreeding Florida coral with Honduran coral to create heat-resistant corals, known as "Flonduran" corals, to combat #ClimateChange bleaching after more than 90% of corals in the Florida Keys has died.
