Healthy coral reefs provide a home for millions of aquatic species. They protect coastal homes from storms and support commercial and subsistence fisheries as well as jobs and businesses through tourism and recreation. Yet they are severely threatened by pollution, disease, habitat destruction and climate change. When corals are stressed, they expel the symbiotic algae living in their tissues and become white (bleached) and vulnerable. Corals are vulnerable to bleaching when the sea surface temperature (SST) exceeds the temperatures normally experienced in the hottest month of the year. The NOAA Coral Reef Watch daily global 5km Coral Bleaching HotSpot product measures the occurrence and magnitude of instantaneous heat stress, potentially resulting in coral bleaching. It highlights regions where the SST is warmer than the highest monthly mean. HotSpot values of 1°C or more indicate heat stress leading to coral bleaching and are highlighted in yellow to dark red colors.

Healthy coral reefs provide a home for millions of aquatic species and numerous ecosystemic services. Yet they are severely threatened. When stressed, corals expel the symbiotic algae living in their tissues and become white (bleached) and vulnerable. The NOAA Coral Reef Watch daily global 5km satellite coral Bleaching Alert Area (7-day maximum) is a composite product that summarizes the current Degree Heating Week (a cumulative measurement of both intensity and duration of heat stress) and Coral Bleaching HotSpot (occurrence and magnitude of instantaneous heat stress) values. At a glance, this layer outlines the current locations, coverage, and potential risk level of coral bleaching heat stress.

Biodiversity hotspots are the Earth’s most biologically rich—yet heavily threatened—terrestrial regions. These are regions where success in conserving species can have an enormous impact in securing our global biodiversity. To qualify as a biodiversity hotspot, an area must meet two strict criteria: it must contain at least 1,500 species of vascular plants found nowhere else on Earth (known as "endemic" species), and it must have lost at least 70% of its primary native vegetation. 36 regions are identified as hotspots by Conservation International and partners, 9 of which lay (partially or fully) in Africa. This dataset shows their location.

This dataset is an index that estimates the relative value provided by coral reefs that protect coastlines through reduction of wave height and wave energy. The value as of 2014 is modelled as a function of exposed populations and infrastructure that received some level of protection from coastal and barrier reefs, and is described in relative terms, classified by decile (i.e., grouped into the most valuable ten percent of reefs for protection, the second-most valuable tenth of reefs, etc.). It was calculated at 1 kilometre (km) resolution globally, encompassing all countries and territories containing coral reefs.

Food crisis response planning can save lives if put in place in a timely manner. To do this, decision makers must be warned of climate extreme events impacting agricultural production. The Anomaly hotSpot of Agricultural Production tool (ASAP) is an online decision support system for early warning about hotspots of agricultural production anomaly (crop and rangeland), developed by the JRC for food security crises prevention and response planning anticipation. This map shows the frequency at which countries were classified as hotspots for agricultural production problems between 2004 and 2018. Hotspots are identified on a monthly basis.
