EO Summit 2025: Call for Sponsors

If you are an EO company and would like to position yourself in front of end users, investors, and other EO companies, then consider sponsoring EO Summit. You need to be where your customers, partners, and investors are.

We have some attractive sponsorship options for all, available on a first-come, first-served basis. Check out the sponsorship brochure.

One Discussion Point

Exclusive analysis and insights from TerraWatch


The Future of EO-Derived Climate Risk Data

The risks associated with climate change are typically divided into two categories: physical and transition risks. Even though they are categorised into two groups, all the climate-driven risks are interconnected. The earlier we take action (i.e. reduce our dependence on fossil fuels and protect biodiversity) managing the transition risks, the more manageable the physical risks might be. The longer we wait, the worse both risks become for everyone.

EO and Climate Risk

Data acquired from the different types of sensors provide crucial information for most of the climate risks. Satellites launched by governmental agencies have been collecting data about the state of the planet and our activities on it for more than five decades. That coupled with data from emerging commercial satellites and a variety of other sensors (drones, aerial, balloons, weather stations and other ground sensors) play a distinct role in understanding climate risk, serving as inputs to the climate models around the world.

Become a member to read the deep dive on EO for Climate Risk which includes an introduction to climate risk, the types of risks, the importance of EO, an overview of the landscape for measuring, reporting and responding to climate risks and some examples of climate risk in use.

Climate Risk in the Real Estate Market

EO-derived climate risk data is becoming mainstream in the real-estate market. It is difficult to think of a future when any large infrastructure or property-related decisions are made without assessing the flood, wildfire, heat and sea level risks, supported by long-term satellite observations and records.

First Street, an US-based organisation that provides climate risk data for real estate firms has had success recently seeing its proprietary models integrated into prominent property marketplaces such as Zillow, Realtor, Redfin, Homes. com etc.

The Black Box Problem

With a growing number of commercial climate risk solutions in the market, one subject that does not get the attention is the the black-box problem i.e. the challenges associated with evaluating the validity and uncertainty of the various climate risks models and benchmarking them.

There is a very limited understanding of the steps involved in the transformation of data derived from satellites into actionable insights, in this case, inputs to the climate risk models. As the figure below shows, different datasets might lead to different results, especially as the output depends on each of the steps in the process, coupled with a possible subjective nature of the contextualised insight.

So, as much as we focus on the role of commercial EO in offering insights to solve a particular climate-related problem, it is equally, if not more, important to be able to fully understand how the insights were derived. Whether it is through continued peer-reviewed publications, complete transparency through an open-source model or simply letting the market decide, that remains to be seen.

Monitoring Phytoplankton Bloom from Space

New research, published recently, revealed that dust carried by the wind from southern Africa towards Madagascar in 2019, delivered essential nutrients and boosted marine phytoplankton growth triggering the largest phytoplankton bloom in two decades. The following image from ESA shows the change in chlorophyll-a using data from ESA's Ocean Colour project, part of the Climate Change Initiative.
