The North Atlantic Current (part of the Gulf Stream system) carries warm tropical water northward, keeping Europe mild and habitable. If it stopped due to freshwater influx or climate change, Europe would plunge into ice-age conditions within decades — while other regions experience opposite effects.

The Amazon holds tens of billions of tonnes of carbon, makes about half of its own rainfall, and shelters roughly one in ten known species. Here is what a total loss would set in motion, and why the forest may not need to be fully cleared to fail.

Antarctica holds about 26.5 million cubic kilometres of ice — enough to raise global sea levels by roughly 58 metres if it all melted. Coastlines would be redrawn, hundreds of cities flooded, and global climate fundamentally restructured.

Somalia, Chad, and Sudan top the Global Climate Risk Index. Small island nations like Tuvalu and Kiribati face complete disappearance beneath rising seas. Bangladesh could lose 17% of its land by 2050. Here's which countries face the greatest climate threat — and the cruel injustice that those most at risk contributed almost nothing to causing the crisis.

WRI's 2023 Aqueduct update puts 25 countries, home to about a quarter of humanity, in the extremely high water stress category. Here is who ranks worst, why the rankings disagree, and what Cape Town, Chennai, the Aral Sea, and Israel show about causes and fixes.

Australia wastes 312 kg of food per person per year — the most in the world. The US wastes 80 million tonnes annually. Globally, one-third of all food produced is lost or wasted — enough to feed every hungry person on Earth twice over. Here's the full picture of global food waste and what the most effective interventions are.

Italy, France, and Spain produce nearly half of all the world's wine. Global production reached 258 million hectolitres in 2023. China is now the world's fifth-largest wine producer. Here's who makes the most wine, how climate change is reshaping the wine map, and which new regions are rising.

Which countries emit the most carbon dioxide depends on how you count. This ranking uses Global Carbon Project data for 2024 and compares annual territorial emissions, per-person emissions, emissions embedded in trade, and cumulative emissions since the industrial revolution.

Species are disappearing tens to hundreds of times faster than the long-run average, and monitored wildlife populations have fallen by about three-quarters since 1970. Here is what the numbers mean, what drives the loss, and what has worked.

Coffea arabica survives in a narrow climate band that is shrinking fast. Here is the science behind why your morning cup is under threat — and what the coffee industry is racing to do about it.

Climate change is happening, it's caused mainly by human emissions, and the evidence comes from thousands of independent measurements. Here's the science, the consequences, and the realistic path forward.

A serious examination of climate change skepticism — the actual claims, the evidence behind them, and why no large-scale scientific conspiracy could survive global scrutiny.
