Exclusive: Federal government court filings claim internal company documents included warnings about products being toxic

Yet, as the climate crisis worsens, the civic space for climate protests is shrinking. Instead of focusing on meeting their commitments to reduce climate change, governments are threatening environmental protectors—from Indigenous communities defending their ancestral lands to young activists protesting the expansion of fossil fuels—with intimidation, legal harassment, and at times deadly violence. New forms of attacks are emerging, like the use of counterterrorism laws against climate activists, who are vilified in public and political discourse. And governments have been ratcheting-up their repression of such protests.

Scientists have linked extreme weather events like excessive heat, flooding and wildfires to big emitter states’ failure to take urgent climate action despite the dangers posed to the rights of those living there and around the world. Governments worldwide are breaking electoral promises, defying court decisions over their lack of climate action, and ignoring warnings that have been voiced by international bodies for years.

In a landmark paper, the UN Special Rapporteur on Environmental Defenders warns that the continued State efforts to repress and criminalise environmental protests, including direct action and civil disobedience, are a threat to fundamental freedoms and democracy itself.

The British-Canadian computer scientist often touted as a “godfather” of artificial intelligence has shortened the odds of AI wiping out humanity over the next three decades, warning the pace of change in the technology is “much faster” than expected. Prof Geoffrey Hinton, who this year was awarded the Nobel prize in physics for his work in AI, said there was a “10% to 20%” chance that AI would lead to human extinction within the next three decades.

Halting and reversing the global decline in biodiversity is now urgent to avoid destabilizing Earth's vital systems that support human well-being. That's the stark message of a new paper published today in Frontiers in Science. The authors warn that without protecting remaining intact biomes and ecosystems, climate and development goals will be impossible to achieve.

A team including scientists, Indigenous people and conservationists point to the ecosystem connecting Yellowstone and the Yukon as an example of a region where humans and nature are flourishing together.

The Earth is already operating beyond its capacity to sustainably support the global population, according to new research highlighting growing strain on food systems, climate stability, and human well-being. Despite this, researchers say that slowing population growth and increasing global awareness could still help reduce long-term risks.

Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people

There is mounting experimental evidence that lifetime exposure to increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. Directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. This has the potential to cause a range of adverse health effects.

Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposure to these increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. However, directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) levels from the U.S. National Health and Nutrition Examination Survey (NHANES) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both Ca and Phave decreased steadily over the same period. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. Studies indicate that, after this time, elevated atmospheric carbon dioxide

Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño

Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30

We live in a world of worry. The ongoing Covid-19 pan­demic, having driven reversals in human development in almost every country, continues to spin off variants unpre­dictably. War in Ukraine and elsewhere has created more human suffering. Record-breaking temperatures, fires, storms and floods sound the alarm of planetary systems increasingly out of whack. Together, they are fuelling a cost-of-living crisis felt around the world, painting a pic­ture of uncertain times and unsettled lives.

The unspoken truth about humanity's frightening future.

New research is warning that the most likely outcome is that human civilization is poised for collapse. As The Guardian reports, a sweeping new historical survey that analyzes 5,000 years and the collapse of more than 400 societies makes the case that we're in for a rude awakening.

As civilization advanced, humans developed tools that allowed us to shield ourselves from the natural cycles that once defined our lives. Fire helped us escape the cold. Irrigation let us shape landscapes around our needs. Walls and weapons kept predators at bay. Over time, these inventions accumulated into infrastructure, then ideology. The more protected we became, the more separated we felt...
