A project of the Thomson Reuters Foundation, AlertNet is a news aggregator that aims to raise awareness of humanitarian crises around the globe, particularly 'forgotten' emergencies that rarely make headlines. It publishes news from over 400 aid agencies and other media outlets across a range of topics, from natural disasters to climate change to health. AlertNet also provides tools for journalists, including facts and figures, crisis briefings and training modules.

The Guardian Environment website publishes news and commentary on environmental issues such as climate change, energy, ethical living, food and recycling.

It also provides blogs, job listings and multimedia, including audio and video podcasts. Users can comment and are encouraged to join discussions.

The website also aggregates relevant news from members of the Guardian Environment Network, which brings together the world's best environment websites including SciDev.Net, China Dialogue, Real Science and the World Resources Institute.

The JTWC public reference website links to data, government departments, organisations and services relevant to tropical cyclones across the world. This includes linking to weather forecasts and bulletins, satellite data, sea surface temperature products and radar imagery. The centre also links to principal news services covering extreme weather and meteorological agencies serving different parts of the world. A selection of training guides and materials is available on topics such as forecasting, satellite image interpretation and disaster preparation among others.

NASA's 'hurricane resource page' provides the latest storm images and data available from NASA together with a tropical weather outlook for the Atlantic Basin. NASA has also published educational tools, including posters and classroom activities that are free for anyone to use. The website includes background information on hurricanes such as fact sheets, lists of satellite instruments used for hurricane monitoring and explanations of how hurricanes form and develop.

RSS publish near-real-time (6–36 hours from time of data collection) maps of sea surface temperatures for cyclone forecasting research. Maps and tracks are available for individual regions and include forecasted paths and wind speeds for tropical storms. Data from two satellites are used to create the maps, which are updated every three hours. An archive of data, including wind speed and track, sea surface temperatures, and rainfall intensity is available for all tropical cyclones since 1999.

TSR is a consortium of experts on insurance, risk management and climate forecasting that aims to help decision-making in the face of tropical storms. It publishes seasonal forecasts for individual oceanic regions. TSR's 'storm tracker' provides access to current satellite images and data on wind speeds as well as maps of the current and predicted paths of 'live' tropical cyclones — from depressions to intense hurricanes. Readers can sign up for email alerts on all tropical storms threatening landfall in different parts of the world.

The WMO's severe weather information centre collates official warnings issued by national meteorological and hydrological services for the media. The centre highlights warnings about tropical cyclones, heavy rain and snow, and thunderstorms. It provides links to regional meteorological centres and offers access to satellite imagery and publishes background information on the terminologies used in tropical cyclone research and forecasting for individual regions.
