Climate change is one of the most written-about subjects online, and one of the easiest to get wrong. The most useful websites are the ones that show you the underlying data and explain how it was gathered.
These sources range from government science agencies to independent data projects and specialist journalism.
1) NASA Climate
NASA studies Earth's climate from space and on the ground. Its climate pages explain the evidence and the causes and track key indicators such as temperature, sea ice and sea level.
Best for: Clear explainers backed by satellite data. Visit NASA Climate
2) NOAA Climate
NOAA experts provide data, tools and information to help people understand, prepare for and adapt to a changing climate. It is the home of many of the US temperature and weather records.
Best for: US climate data and adaptation tools. Visit NOAA Climate
3) Carbon Brief
A UK-based website covering the latest developments in climate science, climate policy and energy. It is known for detailed factchecks and charts.
Best for: In-depth analysis and explainers. Visit Carbon Brief
4) Copernicus Climate Change Service
The European Union's climate service, which publishes monthly climate bulletins and large climate datasets. Its monthly temperature updates are widely cited.
Best for: Monthly global temperature updates. Visit Copernicus Climate Change Service
5) Skeptical Science
Examines the science behind common arguments of global warming skepticism, one claim at a time, with basic and advanced versions of each answer.
Best for: Checking a climate claim you have heard. Visit Skeptical Science
6) Climate Central
Researches and reports on the impacts of climate change, including sea level rise and coastal flooding, extreme weather and local temperature trends.
Best for: Local impacts and sea level maps. Visit Climate Central
7) Berkeley Earth
An independent, non-governmental project that publishes open-source environmental data and analysis, including one of the main global temperature records.
Best for: Independent temperature records. Visit Berkeley Earth
8) National Snow and Ice Data Center
NSIDC manages scientific data about the frozen parts of the planet and educates the public about the cryosphere. Its sea ice updates are a standard reference.
Best for: Arctic and Antarctic sea ice. Visit National Snow and Ice Data Center
9) Our World in Data: CO2 and Greenhouse Gas Emissions
Interactive charts on greenhouse gas emissions by country, sector and over time, with every dataset downloadable.
Best for: Comparing emissions between countries. Visit Our World in Data: CO2 and Greenhouse Gas Emissions
