Climate emergencies on the rise
The devastating impacts of climate change are becoming increasingly evident. In 2022 alone, Hurricane Ian, a Category 5 Atlantic hurricane, wreaked havoc across Cuba, Florida, and the Carolinas, causing over $113 billion in damages and claiming at least 161 lives. This storm is the deadliest hurricane to strike Florida since the 1935 Labor Day hurricane and the third-costliest weather disaster on record worldwide, serving as a stark reminder of the growing threat posed by extreme weather events.
Hurricane Ian is just one example of the many ways climate change is impacting our planet. A report by Christian Aid further highlights this grim reality, estimating that the ten largest natural disasters in 2022 caused a staggering $168 billion in economic losses. These disasters also inflict a heavy human toll, particularly in developing countries. Christian Aid’s analysis shows that these 10 events resulted in at least 3,275 deaths and displaced tens of millions of people.
Moreover, The World Meteorological Organization (WMO)’s State of the Global Climate 2023 report highlights record-breaking levels of greenhouse gases, rising temperatures, and worsening ocean conditions. These factors are fueling extreme weather events such as heatwaves, floods, droughts, wildfires, and intense cyclones, causing widespread devastation and economic losses.
The growing importance of real-time early-warning systems
Despite the grim outlook, proactive measures can lessen the impact of climate-related emergencies. One such measure is the development of early warning and monitoring systems that utilize satellite technology. These systems predict, detect, and track the development of extreme weather events, providing communities with crucial lead time to prepare and evacuate.
Early warning information is disseminated through broadcasts, maritime channels, and other radio communication channels, allowing for timely public advisories and preparation. Finally, satellite data plays a vital role in assessing the extent of damage after a climate-related emergency, informing and optimizing relief operations.
According to the United Nations, these systems can yield a tenfold return on investment by preventing deaths and injuries. Recognizing this importance, the UN Secretary-General set an ambitious goal in 2022: to ensure everyone has access to an early warning system by 2027. The urgency for such systems is further underscored by projections from the WHO, which forecast an additional 250,000 deaths annually due to climate change between 2030 and 2050.
Early warning systems act as the first line of defense by continuously monitoring climate indicators through a network of satellites, ground stations, and sensors. Advanced models then analyze this real-time data to identify potential threats like floods, droughts, or heatwaves — allowing communities to prepare and respond proactively.
For example, early warning systems can monitor the path of cyclones, typhoons, and hurricanes at sea before they make landfall. They can detect hot spots in active volcanoes and monitor volcanic deformation, as well as track the progress of floods in large river basins.
Early warning systems can be classified by the type of hazard they assess (geological, hydrometeorological, biological, etc) and the level they operate at (community, national, regional, global). Satellite data is used across these different types of early warning systems.
Wildfires fueled by climate change rage across the globe
Climate change is fueling a devastating trend of increasingly frequent and severe wildfires around the world. Uncontrolled wildfires, defined as unplanned and unwanted fires burning in natural areas, pose a significant threat to natural ecosystems and human communities. This puts the health and well-being of people across the globe at increasing risk.
California serves as a stark example, with 80% of its most devastating wildfires occurring in the past decade, highlighted by the tragic 2018 Camp Fire, which resulted in 85 fatalities and the destruction of the town of Paradise. Since 2010, the US has witnessed over 50 thousand wildfires each year.
Wildfires aren’t just a US issue. In 2023, Canada shattered wildfire records, with flames consuming over 18 million hectares. It’s been announced that 2023 was Europe’s worst year for wildfires this century and Chile recently battled devastating fires in February 2024 that tragically claimed lives and devastated over 29,000 hectares of land.
Rising temperatures, droughts, and dry conditions create perfect fuel for wildfires. Their unpredictable nature demands reliable risk management tools to protect lives and the environment.
Evolution of wildfire tracking: From traditional methods to satellite imagery
Several traditional methods are still used to track wildfires alongside satellite technology:
- Fire lookouts in towers or on high vantage points scan for smoke plumes visually. This method, however, is limited by the range of human sight and weather conditions.
- Aerial patrols with planes and helicopters can cover larger areas, but they remain expensive and time-consuming.
- Ground teams patrol on foot, providing crucial on-the-ground assessment and fire suppression efforts. However, their reach remains limited.
- Community watch programs rely on residents to report smoke sightings. While valuable for early detection, these programs can be less reliable and lack a comprehensive view.
Satellite imagery revolutionized wildfire management by overcoming these limitations. It provides real-time data and covers most of our planet, making it an indispensable tool for today’s fire response.
Role of thermal satellites in current wildfire early-warning systems
An effective early warning system for wildfires hinges on identifying at-risk areas before flames erupt. This is where satellite technology shines. Thermal satellites, using infrared radiation to measure temperature variations, monitor vast landscapes and detect potential wildfires by identifying high temperatures or moisture-stressed areas.
Notably, thermal imagery is unaffected by smoke but cannot penetrate clouds. The information it provides proves invaluable for pinpointing potential fire zones and tasks like tracking heat islands, monitoring water temperature fluctuations, and assessing soil moisture levels – all crucial aspects of wildfire risk management.
OroraTech’s leading-edge satellite network delivers low-latency, global coverage, near-real-time thermal data products. Recently, the company teamed up with UP42, a geospatial developer platform and marketplace
This partnership brings a thermal-based wildfire solution for real-time detection and monitoring. With OroraTech’s high-resolution thermal data and UP42’s on-demand tasking and archive imagery, it’s possible to easily and quickly create monitoring and early warning systems for at-risk areas.
Furthermore, OroraTech’s tasked data is managed in UP42’s STAC-compatible storage, simplifying the search and management of data for easier processing and integrations.
This innovative system safeguards communities by enabling the detection of fires as small as 4×4 meters and delivering data within 3 minutes, allowing for a swift response and potentially saving millions of dollars per fire.
Building a complete picture of fire behavior using AI
Satellites play a crucial role not only in monitoring wildfires, but also in developing effective response strategies. They provide real-time data on fire spread direction, intensity, estimated size, and burning area, enabling responders to target their efforts and minimize damage to people and property.
However, for truly precise fire behavior prediction, this satellite data needs to be integrated with other critical information. By integrating satellite data with wind, land cover, and slope information, AI models create a comprehensive picture of potential fire behavior, enabling responders to predict fire paths and develop effective response strategies.
By comparing pre-fire and post-fire images, we can create burn severity maps that assess burned vegetation and soil precisely, allowing us to create a clear picture of the fire’s footprint and to track vegetation recovery over time.
Products like OroraTech’s WildFire Solution provide detailed fire origin and spread analysis, high-resolution burn severity maps, and historical fire data to guide restoration efforts, risk mitigation, and future prevention strategies.
Real-life example: Thermal satellites monitoring the Dixie Fire (2021)
The Dixie Fire, which ravaged over a million acres in Northern California in 2021, became the largest single wildfire in the state’s history at the time. Satellites, particularly those equipped with thermal imaging capabilities, were critical in managing this massive blaze.
Throughout the fire’s course, thermal satellite data provided updates every 12 hours on the fire’s perimeter and movement, allowing fire officials to predict the fire’s path and issue timely evacuations for threatened communities.
Strong visuals generated from data empowered incident management to carry out quick and efficient decision-making.
Conclusion on Early-Warning and Monitoring Systems
