"[C]limate change is just a very, very expensive form of tax."

"I believe in climate change caused by human beings. What I'm skeptical about is the glib notion that it means the end of the world as we know it."

"The clock is no longer just ticking, it is banging."

"There is no long-term prosperity without action on climate change."

"The time for seeking global solutions [to climate change] is running out."

"The climate crisis is the existential threat. That's not hyperbole; it's a fact."

"[W]e are killing our planet."

Climate change is "above all, an existential crisis."

"Climate change is one of the greatest challenges mankind faces."

"If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon."

"Humanity is on thin ice — and that ice is melting fast."

"We haven't yet exceeded the bounds of viable human civilisation, but we're getting close."

Is Climate Change an Existential Threat?

Johns Hopkins University researchers analyzed hospital records of 56.5 million U.S. Medicare patients admitted between 2000 and 2014, finding that long-term exposure to PM2.5 air pollution raised the risk of Lewy body dementia by 12% for dementia with Lewy bodies and 17% for Parkinson's disease dementia.

PM2.5 particles are airborne pollutants smaller than 2.5 thousandths of a millimeter that can be inhaled deep into the lungs and are found in the bloodstream, brain and other organs, originating from industrial activity, vehicle exhausts, wildfires and wood burning in homes.</span

Laboratory experiments showed that mice exposed to PM2.5 pollution every other day for 10 months developed brain atrophy, nerve cell death and cognitive decline, while genetically modified mice lacking alpha-synuclein protein remained largely unaffected by the same exposure.</span

The research demonstrated that PM2.5 exposure triggers the formation of toxic clumps of alpha-synuclein protein called Lewy bodies, which are hallmarks of Lewy body dementia and can kill nerve cells as they spread through the brain.</span

Scientists found that PM2.5 samples from China, the United States and Europe consistently induced proteinase-resistant alpha-synuclein strains and brain pathology in laboratory studies, suggesting the harmful effects may be broadly consistent across different regions.</span

Gene expression changes in the brains of PM2.5-exposed mice were strikingly similar to those found in human patients with Lewy body dementia, indicating that pollution may trigger both toxic protein buildup and disease-related genetic changes in the human brain.</span

While pollution correlations exist, diet and nutrition play equally important roles that research often overlooks. Studies show brain-healthy nutrients from meat, fish and eggs can protect against cognitive decline, yet marginalized communities most affected by pollution remain underrepresented in research. Focusing solely on air quality ignores the complex interplay of factors like socioeconomic status, access to healthcare and nutritional deficiencies that truly drive dementia risk.

Air Pollution Linked to Lewy Body Dementia Risk

Pollution

Air pollution isn’t just an environmental crisis — it’s a direct threat to our brains. This massive study of more than 56 million people, backed by lab experiments, shows toxic particles trigger the protein clumps that cause devastating diseases like Lewy body dementia, the second most common form of the disease after Alzheimer's. Scientists are clear: this is preventable. Clean air policies are brain health policies — and bold action to cut emissions could save millions from decline and despair.

Scientists are clear: this is preventable. Clean air policies are brain health policies — and bold action to cut emissions could save millions from decline and despair.

Dementia risk can’t be reduced to air quality alone — it’s shaped by where we live, what we eat, and the resources we can access. Studies show that diet, education, healthcare, and community support all play major roles in brain health, often explaining regional differences as much as pollution does. Focusing narrowly on emissions misses the bigger picture: true prevention demands tackling poverty, nutrition gaps, recreation opportunities and unequal access to care alongside cleaner air.
