Spring Cooling: Hamburg’s Forsythia Blossoming Whopping 17 Days Later Than 30 Years Ago!
By P Gosselin on 23. March 2019
Forsythia are an indicator plant used by the German DWD Weather Service for marking the beginning of spring in March. The trend of spring blossoming show that springs in Hamburg have been cooling over the past 30 years.
The north German port city of Hamburg happens to have a long data series on the the date the plant blossoms and so it has some use as a spring climate tracker for that perticular region.
An ever increasingly earlier blossoming of the plant is claimed to be evidence by alarmists of climatic warming, which would be again exclusively CO2’s doing.
It is often suggested that the forsythia only blossomed in May 40 years ago and now the date has since moved forward.
