Suur probleem on selles, et kuna põhjapoolkera on oluliselt suurema maismaa osakaaluga kui lõuna, siis enamus inimesi elab seal ja enamus mõõtmisi tehakse põhja pool ning muutused põhjas paistavad tänu sellele rohkem silma.
Tegelikkuses on põhja- ja lõunapoolkera kliima muutused erinevad (tänu suurele ookeani pinnale?) ja sageli sellest ei räägita. "Me" kirjutame Alpi liustike ja Arktika jää vähenemisest kuid ei taha rääkida Antarktika jääkilbi suurenemisest ja laienemisest … Lihtsalt ei sobi teooriasse?
Uuringud on näidanud, et siiski lõunas jääkatte suurenemine on aeglasem kui sulamine põhjas, kuid täpsemad mõõtmistulemused on ikkagi ainult viimase 40-aasta ajavahemik.
Kas soojenemine on ikka ainult (või vähemalt suures osas) inimese mõjul?
Tsiteeri:
Between 1989 and 1993, US and European climate researchers drilled into the summit of Greenland's ice sheet, obtaining a pair of 3 km (1.9 mi) long ice cores. Analysis of the layering and chemical composition of the cores has provided a revolutionary new record of climate change in the Northern Hemisphere going back about 100,000 years and illustrated that the world's weather and temperature have often shifted rapidly from one seemingly stable state to another, with worldwide consequences. ... Scientists who probed 2 km (1.2 mi) through a Greenland glacier to recover the oldest plant DNA on record said that the planet was far warmer hundreds of thousands of years ago than is generally believed. DNA of trees, plants, spiders and insects including butterflies from beneath the southern Greenland glacier was estimated to date to 450,000 to 900,000 years ago, according to the remnants retrieved from this long-vanished boreal forest. That view contrasts sharply with the prevailing one that a lush forest of this kind could not have existed in Greenland any later than 2.4 million years ago. These DNA samples suggest that the temperature probably reached 10 °C (50 °F) in the summer and −17 °C (1.4 °F) in the winter. They also indicate that during the last interglacial period, 130,000–116,000 years ago, when local temperatures were on average 5 °C (9 °F) higher than now, the glaciers on Greenland did not completely melt away.
https://en.wikipedia.org/wiki/GreenlandNagu kunagi eespool mainisin, siis
minu isiklik arvamus on , et kogu praegune kliimasoojenemise paanika on poliitiline- ja äriprojekt. Ning natuke ka mingit moodi religioosne liikumine...
