Shockwave from Hunga Tonga-Hunga Haʻapai volcano measured in Germany – an examplary event to think about

Our air knows no boundaries and it is quite exhilarating to see that the shockwaves produced by the Hunga Tonga-Hunga Haʻapai volcano eruption almost 16.800km away were measured by our instruments deployed around Frankfurt (see chart). The shockwave travelled almost 16 hours. Not only that, but it seems that the same shockwave travelled around the globe and reached the same point another 18 hours later!

Why this is relevant? This exemplifies that our atmosphere knows no boundaries. And that events from emissions to eruptions ripple across the globe. Some of these events happen in slow motion, but they do happen and do have a measurable effect today. Read more

Background to Climate and Climate Change


“Climate change is the greatest threat of the future. Every state must cooperate in combating the causes and mitigating the consequences.” (Klaus Töpfer)

The word climate comes from Greek and essentially means “inclination” or “curvature”. It does not mean the inclination of the Earth’s axis but the curvature and coherence of the Earth itself. The totality of weathers events is called climate. Weather is local, and climate is global. The larger and more complex a system, the slower it changes, and climate is arbitrarily complex. Read more
