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.

The US was an oligarchy well before Trump’s first term. Recognizing this reality is essential to building a true democracy

 As climate protests are mounting across Italy, there is a corresponding escalation in repressive responses from public authorities. This trend is not unique to Italy but is rather widespread throughout Europe, as evidenced by frequent reports in national newspapers... What sets Italy apart from other European nations is the spectacular increase in the use of preventive measures by the public security administration.

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

El Niño could fuel extreme weather and raise temperatures to record highs this year, but how sure can we be that it will return?

Depleting THAAD and Patriot interceptor inventories threaten US extended deterrence, Gulf energy security, and the regional power balance amid sustained Iranian ballistic missile and drone assaults.

In one of the most comprehensive empirical studies to date of AI strategic reasoning, Professor Kenneth Payne of King’s College London examined how large language models navigate simulated nuclear crises. Across 21 scenarios, the models displayed sophisticated escalation logic consistent with classical strategic theory – yet nuclear signalling occurred in 95% of games and no model ever chose outright concession. The findings challenge assumptions about AI restraint and offer new tools for defence analysis.

A recent UK national security assessment on biodiversity and ecosystem collapse made headlines, not for its dire warnings, but for its omissions. It's part of a larger trend of governments keeping climate security reports from the public.

The new joint policy brief offers a deep dive into the ways in which the social and solidarity economy can advance the objectives of the Roadmap by supporting the eradication of poverty beyond growth.

Even as weather extremes worsen, the voices calling for the rolling back of environmental rules have grown louder and more influential

Extinction Rebellion says some members have been visited by agents claiming to be FBI amid Trump’s threats toward liberal groups

The world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.

China’s carbon dioxide (CO2) emissions fell by 1% in the final quarter of 2025, likely securing a decline of 0.3% for the full year as a whole.
