Trú, von og manngert veđur

„Af hverju ćtti hann [Trump] ađ vilja hitta mig; tán­ing og lofts­lagsađgerđasinna, ţegar hann trú­ir ekki á vís­ind­in sem búa ađ baki?“ er haft eftir Grétu Thun­berg.

Ţađ er hćgt ađ setja mćlistiku á vísindi, ekki á trúarbrögđ. Loftslagsvísindamađurinn John Christy mćldi spár IPCC, stofnunar Sameinuđu ţjóđanna sem gefur út skýrslur um loftslagsmál, og komst ađ ţeirri niđurstöđu ađ spárnar stóđust ekki raunmćlingar.

Spálíkön IPCC spáđu ţrisvar sinnum meiri hlýnun en raunmćlingar sýndu. Ef allt vćri međ felldu yrđi ekki tekiđ mark á stofnun eins og IPCC. En vegna Grétu og fullorđinna samverkamanna hennar eru falsspár IPCC gerđar ađ trúarbrögđum.

Vísindi eru ađferđ til ađ skilja heiminn. Trúarbrögđ eru til ađ breyta heiminum. Hugur Grétu og samverkmanna stendur til ađ ţvinga á heimsbyggđina trú á manngert veđur. Ef ţeim tekst ćtlunarverk sitt byrja hörmungarnar fyrir alvöru.

Spálíkön sem sjá ekki fyrir hćkkun á hita vegna C02 eru blind í báđar áttir. Ţađ er fráleitt ađ reyna ađ lćkka CO2 í ţeirri veiku von ađ hiti lćkki. Og til hvers? Er nóg ađ fara  međ veđurtrúarjátninguna til ađ fá fría ţotuferđ á loftslagsráđstefnu, frítt hótel og skemmtilegan félagsskap á kostnađ skattgreiđanda. 

"More CO2 makes plants grow faster, and with less stress and less water.

Forests are growing faster in response to increasing CO2.

More CO2 stimulates growth of beneficial bacteria in both soil and water.

CO2 fertilization, leading to more plant growth, means less erosion of topsoil.

More CO2 means bigger crop yields, and more and bigger flowers.

More CO2 fosters glomalin, a beneficial protein created by root fungi.

More CO2 means less water loss, less irrigation, and more soil moisture.

More CO2 helps plants to create natural repellants to fight insect predators. 

Conversely, a large number of studies show the adverse effects of a low-CO2 environment. For instance, Overdieck (1988) indicated that, compared to today, plant growth was reduced by 8% in the period before the Industrial Revolution, with its low concentration of 280 ppm CO2. While it is only common sense that plants thrive in response to higher CO2 concentrations, it is also relevant that the ancestors of the plants on which we rely first evolved and prospered when CO2 levels were up to 10 times today’s levels.

Therefore, the proposed attempts by climate extremists to reduce CO2 concentrations would be bad for plants, bad for animals, and bad for humankind. Although I do not pretend to speak for the planet’s flora, I am quite certain that, if plants had a say in the matter, they would not be lobbying for reductions in CO2 levels. For plants, CO2 is food. They need more of it, not less. Inconvenient Fact 9 More CO2 means moister soil. Figure I-15: Crop yield growth and cash benefit with 300 ppm more CO2 (based on 3,586 experiments on 549 plant species)" (from "INCONVENIENT FACTS: The science that Al Gore doesn't want you to know" by Gregory Wrightstone)
