What Is a Carbon Footprint?
A carbon footprint is the total greenhouse gases attributable to a person, product, or organisation. Here is how it is measured and what it includes.
Section
Climate
A warming planet, the energy transition, and the choices that come next. This section covers climate as a subject with settled physics and genuinely contested policy, and tries to keep the two clearly apart. The greenhouse effect is well understood; what a country should do about it involves trade-offs that reasonable people weigh differently.
Coverage spans the technical and the commercial — how solar panels turn sunlight into electricity, what a carbon offset actually represents and why the market for them draws sustained criticism. Where a mechanism is doing less than its marketing implies, we say so plainly and show the reasoning rather than simply assigning blame.
Climate
What Is Net Zero?
Net zero means balancing the greenhouse gases put into the atmosphere against those taken out. Here is what net zero means and how it is measured.
Climate
What Is Renewable Energy?
Renewable energy comes from sources that nature replenishes on a human timescale, such as sunlight, wind and water. Here is how it works and why it matters.
Climate
What is El Niño, and how does it change weather worldwide?
El Niño is a periodic warming of the tropical Pacific that shifts rainfall and storm tracks worldwide. It is natural, irregular, and distinct from climate change.

The Greenhouse Effect, Explained
How a thin blanket of gases keeps Earth warm enough to live on — and why adding more of them is changing the climate.

Inside the photovoltaic effect: how a slab of treated silicon converts light into usable electric current, with no moving parts.

Carbon Offsets: What They Are, and Why They’re Controversial
Buying a credit to cancel out emissions sounds simple — but the value of an offset depends on claims that are hard to verify.
