For Students & TeachersClimate Science for Students & Teachers

Plain-English guide to the greenhouse effect, feedback loops, tipping points and the Paris Agreement. The best starting point for any student.

Atmospheric CO₂, methane and N₂O from ice-core records through to today. Covers the chemistry and sources of each gas.

Live disaster alerts and 60-year EM-DAT trends for floods, wildfires, droughts, cyclones and heatwaves. Excellent for hazard case studies.

Country-level annual emissions, per-capita rankings and cumulative historical totals. Essential for responsibility and policy discussions.

The latest headline figures - global temperature, the 1.5°C Paris limit, CO₂, El Niño / La Niña and sea ice - plus a guide to every climate page. A quick way into the data.

A monthly climate page for every continent, country, US climate region, US state and UK region - temperature, rainfall, shifting seasons and climate history. Ideal for local case studies.

Every continent, country and region on one map - temperature anomalies, warming trends, rainfall, frost, snow and heatwaves. Shows the geography of change at a glance.

Warmest and coldest years on record, this year's rank and the Top 10 for every place. Useful for testing claims such as 'the warmest year on record'.

Live whole-planet temperature anomalies, CO₂ concentration, sea ice and ENSO state in one dashboard. Ideal for illustrating current conditions.

The nine Earth-system thresholds defining a safe operating space for humanity. A core framework in IB ESS and A-level.

Sea level rise, ocean warming and Arctic / Antarctic ice extent with long-term charts. Key data for coastal and cryosphere topics.

El Niño and La Niña - live state, NOAA forecast and global impacts on rainfall, droughts and temperatures. Covers ocean-atmosphere coupling.

The Atlantic Ocean conveyor (thermohaline circulation) measured directly by the RAPID and OSNAP arrays, with an animated map, an interactive tipping-point model showing hysteresis, and a clear guide to why scientists disagree about a slowdown.

Daily heat stress for 214 coral reef regions from NOAA satellites, with Degree Heating Weeks, bleaching alert levels, every year since 1985, the four-month outlook and the link to El Niño. A live case study of a tipping point and of ocean warming hitting an ecosystem.

How climate change is moving spring and autumn timing worldwide. Real phenology data ideal for ecosystem and biosphere topics.

One loop per year - temperature, rainfall, sunshine and frost since records began, for the globe and every country and region. Makes the long-term warming trend visually unmistakable - excellent for presentations and coursework.

Temperature since 1950 for every country and region, set against rainfall, frost, snow, CO₂ and SO₂ - with climate eras, sourced climate events and night warming. Good for the causes of warming, including air pollution masking it.

Heatwave days each year since 1950, using the WMO Warm Spell Duration Index, for the world, countries, US states and UK regions - with an El Niño / La Niña overlay.

Every major climate driver on one live timeline - ENSO and the Indian Ocean Dipole, the PNA, the NAO and polar vortex, and the slow Atlantic (AMV and AMOC) - grouped to show how they connect, with the NOAA ENSO forecast and a What-If explorer. Shows how climate drivers interact and amplify each other.
