CO2 concentrations have increased by nearly 53ppm in my lifetime. That's honestly incredible. A 15% increase in global atmospheric CO2 in 28 years.
- Earlier this month atmospheric CO2 levels broke 415ppm for the first time in human history. - In the year of my birth the level was c. 335ppm. - Here's the Mauna Loa annual April average data for ppm since 1958; check your own birth year's level. #ClimateStrike

In my day, the word “Awesome" was reserved for things like curing Polio and walking on the Moon, not for food or TV shows.
