A new study finds two persistent mental shortcuts—not ignorance—are why people keep overrating recycling and underrating flying less.
Our roadmap has been shaped by experts across the world, from UN agencies to grassroots movements. We call on political leaders at all levels to use it
The US was an oligarchy well before Trump’s first term. Recognizing this reality is essential to building a true democracy
One of the world’s most climate-ambitious governments is about to fall, replaced by a likely chancellor who says green policy went too far.
Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989
In recent years, governments of several low-income countries have taken decisive action by removing fully or partially user fees in the health sector. In this study, we review recent reforms in six sub-Saharan African countries: Burkina Faso, Burundi, Ghana, Liberia, Senegal and Uganda. The review d …
By replacing thousands of equations with just one, ecology modelers can more accurately assess how close fragile environments are to a disastrous “tipping point.”
The accelerating thaw of Antarctica might drive sea levels up by more than five metres by 2300 unless governments act quickly to cut greenhouse gas emissions, a UN report said on Wednesday.
A Belgian climatologist surveys the wreckage of his hometown. Pierre Ozer has been expecting these floods for decades.
