Let’s give young people something really useful this Christmas: hope!

The speech delivered by Greta Thunberg to the UN plenary at COP24 in Katowice was truly amazing. Not only does it take guts for a teenager to tell the world to grow up, she also made more sense than most politicians ever have. I am not the only one saying this. Here are some reactions on Twitter:

Naomi Klein: Ok Greta, you are officially a superhero.
Michael Mann: Thank you Greta — one person can indeed change the world…for the better. You are proving it. 
Kevin Anderson: On climate change @GretaThunberg demonstrates more clarity & leadership in one speech than a quarter of a century of the combined contributions of so called world leaders. Willful ignorance & lies have overseen a 65% rise in CO2 since 1990. Time to hand over the baton.

I was particularly impressed with her using the term emergency brake. The message could not be simpler: only if we are prepared to change our lives completely, our children will have a future. Very few people realize this. This is what makes the interview with Greta and her father so important.

We all know what we need to do. So, stop flying, stop buying, and change your eating habits. You will be happier, more relaxed, and have more time for important stuff. And you will give your children a chance to live. That would be an excellent Christmas gift and it wouldn’t cost you anything.

BTW, if you aren’t already convinced about the need to act, I can recommend this video.

I wish you all happy and relaxing holidays.

Exxon was right!

Some remarkable documents have emerged from major oil companies in recent years. Obviously, they have long been aware of the effects of greenhouse gases on the Earth’s climate. Still, it is shocking to see to what extent they understood the problem of global warming already in the 1980s. An internal report by Exxon from 1982 contains a forecast for the global average temperature of the Earth (cf. Shell and Exxon’s secret 1980s climate change warnings, The Guardian 2018-09-19).


I have allowed myself to add the actual development of the temperature (annual averages as red stars). Obviously, the Exxon scientists were correct. Faced with such evidence, the Exxon management took the decision not only to continue to sell oil, but also to use their economic power to influence the political and scientific process. Greed is not good!
