I posted this 2 years ago. After which we experienced 2 years of 1.6°C above the Paris' pre-industrial (1850-1900) baseline. We expected a big jump in global warming because greenhouse gas emissions keep increasing, aerosols decreased and Earth's Energy Imbalance had doubled.

This might be the year everything changes, as those who don't count joules and radiative fluxes are too starting to feel the heat from reducing air-pollution. Many great scientists have tried to inform on this in the past decades (e.g. James Hansen, James Lovelock, Paul Crutzen.

My mother passed away recently. I'm glad she still got to see the beautiful documentary made of our brother, her son, Floris. It broadcast again on Dutch TV today. We lost so many loving people in the past years, it's hard to bear.

My brother Floris passed away in Madagascar, where he was helping local farmers to grow malaria medication (Artemisia annua 👇). The story of his life will air on Thursday, October 3, at 20:20, as part of the Break Free documentary series, on Dutch tv @NPO3 and online.

We're going to need a bigger y-axis. Again. '343,000 hectares have been destroyed this year in Spain, setting a new national record, according to the European Forest Fire Information System (EFFIS)'. Our white car is covered in soot from South European wildfire smoke.

Dr James Hansen talked about the Venus Syndrome (greenhouse effect is about +500°C! 🤯) and using the climate of Venus as an indicator of Earth's climate, which is now 'just right'. See the fulll Climate Chat covering Hansen's recent work linked below.

This is when experts in the Netherlands start checking the astronomical tide:.The worst flooding happens when a strong Western storm increases sea-level and waves, and when the moon is closest to the sun, or furthest away, as that's when the tides are highest:

Erin will generate massive 40 to 50 foot waves across the Atlantic over the next week, including up to around 20 feet near Bermuda. Eventually, the stormy conditions may reach Ireland!
