International experts converge to explore the role of Earth Observation in enhancing blue carbon ecosystems for climate change mitigation.
Space weather has affected aviation in many ways; effects include short-wave radio disturbance, single-event effects leading to upsets in electronics, Satellite Navigation systems disturbance via scintillation, solar radio burst effects on secondary surveillance radar, increased radiation dose at flight altitudes. In November 2018, a long process involving experts from many countries of the world came to a conclusion when the ICAO Air Navigation Commission and the Council of ICAO, the International Civil Aviation Organization, approved and published provisions in ICAO Annex 3 and guidance material on Space Weather in ICAO Document 10100. The advisories intend to provide the most up to date information on space weather impacts on aviation. The introduction of space weather in the ICAO framework has been a great achievement. What is still outstanding is the development of procedures that are globally standardized on the application of the advisories, as well as the provision of adequate space weather knowledge to pilots, controllers and other aviation personnel. Recent events are used to illustrate this. The talk will be about space weather for aviation: what´s been achieved – and what needs more work.
Human activities have become a dominant force of terrestrial transformations, inducing a clearly observable change of the climate, ubiquitous pollutions of air, soil and water, and an unprecedented decrease of the living. Faced with this situation, the assessment of the environmental footprint of human activities becomes a key instrument to inform sustainability action plans and roadmaps. In this webinar the speaker summarises the current knowledge on the environmental footprint of Space Sciences, explaining its origins and impacts. A particular focus will be placed on the carbon footprint of astronomical research, for which detailed estimates are becoming available. Forecasts for the evolution of the field will be discussed and confronted with the imperative to drastically reduce green house gas emissions over the coming decades. The speaker demonstrates that profound changes are required for making Space Sciences environmentally sustainable.
There is life on Earth thanks to the energy we get from the Sun. But how exactly does the Sun and our space environment result in a habitable climate? Some of the energy we get directly as radiation, some as charged particles from the solar wind and Earth’s magnetosphere. In this seminar, we learn how these two distinct sources influence our atmosphere and what the implications to Earth’s climate are. We particularly focus on the influence of charged particles of solar and magnetospheric origin, a pathway recently included for the first time in the climate simulations informing the Intergovernmental Panel on Climate Change (IPCC).
