Scientists say the Southern Hemisphere ozone hole is larger than usual and already surpasses the size of Antarctica. The European Union's Copernicus Atmosphere Monitoring Service said Thursday that the ozone hole, which appears every year during the Southern Hemisphere spring, has grown considerably in the past week following an average start.

Sometime in our recent past, we became obsessed with planting trees. First, the goal was 1 billion new trees worldwide. Now it’s 1 trillion by the year 2030. Trees offer all kinds of benefits, from absorbing climate-warming emissions to providing refuge for animals, and we’re losing them at a blistering pace. But in our push to restock the world’s forests, we’ve largely ignored — and in some cases harmed — another important ecosystem that offers a similar set of benefits: grasslands.

Jamie Henn, a co-founder of the climate group 350.org, had for a long time noticed a gap in climate advocacy that many had overlooked: while the fossil fuel industry pours money into ad campaigns, much of the climate movement simply doesn’t have the resources to do that work.

The price per ton of direct carbon removal is still much too high.

A new study doesn’t examine that idea. Rather, it asks: We know that extraction and production processes are not as clean as they could be. So, essentially, what is the impact of those? In the United States, burning fossil fuels account for 74 percent of the nation’s greenhouse gas emissions, which isn’t new information exactly. However, scientists suggest that focusing on just the air pollution doesn’t show the full extent of the damage done.

Without a legal standard setting out what must be done to prevent heat deaths, workplace regulators have a hard time making violations stick.

Plans for the future include a new 25-acre wood to remember those who've died during the COVID-19 pandemic.

There is a growing sense, among young people as well as older demographics, that humanity is in deep trouble, and that extracting ourselves from our current predicament is going to take a concerted effort unlike anything our species has attempted in recorded history — if it's possible at all. The IPCC recently issued a "code red for humanity" about climate change, as the UN Secretary-General António Guterres put it, adding that "the alarm bells are deafening."

Warming of the Arctic caused by climate change has increased the number of polar vortex outbreaks, when frigid air from the far north bathes other parts of the Northern Hemisphere in killer cold, a new study finds.

Exclusive: research finds small rise in exposure to air pollution leads to higher risk of needing treatment

The average person is losing about 2.2 years of life expectancy due to air pollution, according to new research by the University of Chicago’s Energy Policy Institute.

Food and water were thought to be the main ways humans are exposed to PFAS, but study points to risk of breathing them in

Leaded gasoline has finally reached the end of the road, the UN environment office said Monday, after the last country in the world to use it stopped selling the highly toxic fuel.

Polystyrene cups will also be banned but campaigners say action to cut plastic waste is ‘snail-paced’

The government has announced plans to ban single-use plastic cutlery, plates and polystyrene cups in England as part of what it calls a "war on plastic". Ministers said the move would help to reduce litter and cut the amount of plastic waste in oceans. A consultation on the policy will launch in the autumn - although the government has not ruled out including other items in the ban.

We have forgotten the primeval forests and expansive grasslands where wildlife thrived, an ecological amnesia. We must work to remember, regenerate, and restore

Thousands of coronavirus cases and hundreds of deaths may be attributable to the particulate matter in wildfire smoke

Animal health experts and UN leaders have called for a significant reduction in antimicrobial drug usage in food animals, which is already causing a “silent pandemic”. But critics say the statement is “a real missed opportunity”, pointing to its failure to set reduction targets or even call for a ban on the use of antibiotics for animal growth promotion.

Huge amounts of plastic ends up rivers and oceans every year, harming the environment and potentially also human health. But what if we could pull it out of water with magnets?

Smoke from the raging wildfires in the West Coast was so severe that it created an air quality alert as far as Reno, Nevada, on Tuesday. Several Nevada counties reported their worst recorded air quality index numbers in the two decades they’ve been monitoring air quality.
