Trś, von og manngert vešur

„Af hverju ętti hann [Trump] aš vilja hitta mig; tįn­ing og lofts­lagsašgeršasinna, žegar hann trś­ir ekki į vķs­ind­in sem bśa aš baki?“ er haft eftir Grétu Thun­berg.

Žaš er hęgt aš setja męlistiku į vķsindi, ekki į trśarbrögš. Loftslagsvķsindamašurinn John Christy męldi spįr IPCC, stofnunar Sameinušu žjóšanna sem gefur śt skżrslur um loftslagsmįl, og komst aš žeirri nišurstöšu aš spįrnar stóšust ekki raunmęlingar.

Spįlķkön IPCC spįšu žrisvar sinnum meiri hlżnun en raunmęlingar sżndu. Ef allt vęri meš felldu yrši ekki tekiš mark į stofnun eins og IPCC. En vegna Grétu og fulloršinna samverkamanna hennar eru falsspįr IPCC geršar aš trśarbrögšum.

Vķsindi eru ašferš til aš skilja heiminn. Trśarbrögš eru til aš breyta heiminum. Hugur Grétu og samverkmanna stendur til aš žvinga į heimsbyggšina trś į manngert vešur. Ef žeim tekst ętlunarverk sitt byrja hörmungarnar fyrir alvöru.

Spįlķkön sem sjį ekki fyrir hękkun į hita vegna C02 eru blind ķ bįšar įttir. Žaš er frįleitt aš reyna aš lękka CO2 ķ žeirri veiku von aš hiti lękki. Og til hvers? Er nóg aš fara  meš vešurtrśarjįtninguna til aš fį frķa žotuferš į loftslagsrįšstefnu, frķtt hótel og skemmtilegan félagsskap į kostnaš skattgreišanda. 

"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)
