A warming climate is changing the vegetation structure of forests in the far north (Montesano et al., 2024). It’s a trend that will continue at least through the end of this century, according to NASA researchers.

Can LST Help Predict Earthquakes?
In Taiwan, earthquakes are linked to shallow stores of magma. New research (Chan et al., 2023) explores this connection by finding a positive correlation between land surface temperature and earthquakes. Though preliminary, this research could have implications for future hazard mitigation efforts.

During this year's virtual Camp Landsat campaign, the Landsat Outreach team unveiled the “Your Name in Landsat” interactive web tool. Within the application, the user writes their name—or any message they want—and the tool displays a Landsat image for each letter. The result is a beautiful, shareable graphic based on Landsat imagery.

Deforestation amplifies climate change effects on warming and cloud level rise in African montane forests
| Abera et al., 2024
Tropical montane forest ecosystems are important for safekeeping biodiversity and providing ecosystem services like fresh water. In Africa, these critical ecosystems are threatened by deforestation, which amplifies the effects of climate change. In a paper published this month in Nature Communications, researchers found that deforestation caused an increase in air temperature of about 1.37°C and an increase in cloud base height of about 236 meters in less than 20 years in montane forests in Africa. The researchers analyzed Landsat imagery to reveal that approximately 18% of Africa’s montane forests were lost from 2003 to 2022, then used data from both MODIS Terra and Aqua sensors to calculate deforestation-induced temperature change for each pixel. This research emphasizes the cascading effects of deforestation in montane ecosystems.
