European lawmakers issued a stark warning about the region’s growing water crisis ahead of another extreme summer, saying there is a pressing need to tackle issues such as scarcity, food security and pollution.

Mica, aged 15, learned about climate change at the young age of four, when his parents showed him the documentary Chasing Ice. “I understood it more than my parents thought I would,” he testified in a groundbreaking trial on Tuesday. “I just knew something bad was happening, but I didn’t know exactly what it was.”

A wildfire season like no other has tested Canada’s airborne firefighting capacity, revealing that one of the most forested countries in the world may be ill-equipped to deal with fires raging simultaneously from coast to coast.

Political misinformation continues to swirl around the climate change discussion like a thick fog rolling in off the rising ocean. But a host of government documents and reports by researchers and historians lay a clear trail of what scientists and government officials knew and when.

As the climate crisis worsens, so does pressure on wildlife. The number of birds in North America has declined by 3 billion in the last 50 years.

Sixteen young people who say the state isn’t doing enough to address climate change will get their day in court Monday. The lawsuit argues that lack of action violates plaintiffs’ rights under the state Constitution. This is the first youth climate lawsuit to ever make it all the way to trial in the U.S.

While headlines this week in the United States focused on historic levels of air pollution in major East Coast cities like New York and Philadelphia—which have not experienced air quality conditions this poor since the Clean Air Act was passed in 1970—in Canada, it was the unprecedented wildfires themselves that remained the primary worry.

Wildfires are just one example of our governments’ collective failure to face down massive systemic challenges.

In a new study, scientists found that the climate milestone could come about a decade sooner than anticipated, even if planet-warming emissions are gradually reduced.

Don’t go outside. That’s what public health officials and medical experts have been advising tens of millions of people in the U.S. over the last couple of days as smoke from raging wildfires in Canada has drifted into the U.S., triggering air alerts and grounding flights across the Northeast, as far south as South Carolina and as far west as Minnesota.

The vast majority of the world’s biggest companies have done almost nothing in the past five years to cut their planet-heating pollution enough to avoid catastrophic climate change.

Several significant landslides associated with rapid snowmelt in western North America in May 2023, driven by exceptional temperatures.

A 75 percent reduction is needed to limit warming to 1.5 C, new report says.

People once believed the planet could always accommodate us. That the resilience of the Earth system meant nature would always provide. But we now know this is not necessarily the case. As big as the world is, our impact is bigger.

Rich countries promised $100 billion a year to reduce the effects of global warming. Reuters found large sums went to a coal plant, a hotel and chocolate shops.

The ban on gas in new buildings could face legal challenges, but marks a new milestone in the energy transition sought by climate activists.

Reducing global greenhouse gas emissions is critical to avoiding a climate disaster, but current carbon removal methods are proving to be inadequate and costly. Now researchers from the University of California, Berkeley, have proposed a scalable solution that uses simple, inexpensive technologies to remove carbon from our atmosphere and safely store it for thousands of years.

New book details how New York could rid the city of rats and create more parks if it repurposed its 3m parking spots

There’s a 66% chance that the annual global average temperature will hit 1.5 ºC above pre-industrial temperatures at some time in the next five years, according to a World Meteorological Organization report released on 17 May. Reaching 1.5 ºC of warming in a single year will be a landmark moment for the planet, which in 2022 was about 1.15 ºC warmer than in pre-industrial times.

If a multiday blackout in Phoenix coincided with a heat wave, nearly half the population would require emergency department care for heat stroke or other heat-related illnesses, a new study suggests. While Phoenix was the most extreme example, the study warned that other cities are also at risk. Since 2015, the number of major blackouts nationwide has more than doubled.
