Spiegel science journalist Axel Bojanowski at Twitter posted a couple of comments that got me wondering about man’s role on climate.
The first comment was a tweet about NASA’s Jim Bridenstine who reportedly went from being a “climate denier” to changing his mind and confirming that “climate change is caused by humans”.
Readers will note that there’s nothing new here. Almost all climate skeptics will say that no one doubts that humans are playing a role in climate. But again, for the umpteenth time, the debate is: to what extent?
Changing sun and oceans no longer playing a role?
Today alarmist scientists would have us believe that that big bright tempestuous star up there in the sky stopped playing a role since the late 19th century, and that the oceans, which cover a puny 70% of our planet’s surface (sarc), also stopped playing a role.
Instead the alarmist scientists insist that today’s climate is being 90+% driven by human-emitted CO2 and the rest of the factors have been somehow disabled. If that sound preposterous, then it might have something to do with how you perceive the your planet and how different parts are interrelated.
Humans only 0.01% of world’s biomass
So how does that 90+% driver compare in scale to the rest of planetary factors? That brings us to Bojanowskis’s second comment that pricked my attention, citing the PNAS: humans make up only 0.01% of the world’s biomass.
Wir fallen nicht ins Gewicht:
Pflanzen machen 80% der Biomasse aus, Bakterien 15%, Tiere 0.3%, Menschen 0.01%:https://t.co/PNBak4XLPa

Plants make up 80%, bacteria a whopping 15% and animals 0.3%. So of all the biomass on the planet, we are only one hundredth of a percent.
Human CO2 only 0.01% of atmosphere
Through the burning of fossil fuels, humans are also responsible for having boosted atmospheric CO2 emissions from some 300 ppm to 400 parts per million, which translates into a difference of 0.01% of the atmosphere. So what do the alarmists conclude from this:
0.01% of the world’s biomass and 0.o1% of the atmosphere are today almost solely responsible for climate changes.
The sun, oceans, volcanoes and other poorly understood major varying factors are ignored. Does all that sound plausible?
Yeah right, and the price of tea in China drives the global economy.
