students have discovered about it.
Insights
from Adriana Mlynska, teacher at
J.A.Baťu Secondary School of Polytechnics in Slovakia
The expert webinar organised by GLOBE Ireland as part of the
Climate Resilience – Temperature and Trees campaign. The
campaign helps students explore the connections between our built and
natural environments.
UPCOMING: Climate Resilience: Temperature and Trees Campaign
International Student webinar
📅 25
November 2025, 10:00 UTC
Join the international student webinar hosted by GLOBE Ireland to
hear GLOBE students presenting their measurements on surface
temperature (Urban Heat Island), trees, and phenology (Green
Up/Down). Connect with students from Europe, Eurasia, and
Africa to compare data and explore how trees help cool hot areas.
Join us as we discuss the upcoming 2025-2026 campaign,
specifically: satellite missions, and Intensive Observation Periods
(IOPs) for tree height, land cover, and greenings. We will also
discuss about getting an early start to the GLOBE 2026 IVSS for
projects that align to the Trees Around the GLOBE Student Research
Campaign. We also want to hear from you, our amazing campaign members,
about what you what to see, hear about, and learn about, during Year 8
of the campaign. We are excited for you to join us!
Please send an email to Campaign Lead, Brian
