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.

Antarktika jääkilbi suurenemisest ja laienemisest

Kas soojenemine on ikka ainult (või vähemalt suures osas) inimese mõjul?

Vaevalt küll, need laetud osakesed ei soojenda suurt midagi. Soojenemine on ikka kasvuhooneefekti teema.

Päikesest lähtuv kiirgus ei soojenda midagi?? Vabandust aga ainult see ju maakera soojendabki - või sain millestki valesti aru?

Sa rääkisid ju magnetvälja vähenemise tõttu Maani jõudvatest osakestest, mitte päikesekiirgusest üldiselt?

Since 2015, the bulk of scientific research suggests that Antarctica is losing more ice than it's gaining. This research includes:

A 2017 study that found East Antarctica is gaining three times less ice than Zwally's team proposed it was.
A 2018 NASA study that found the continent's ice loss has accelerated since 2008, with about 90% of losses occurring in West Antarctica.
A 2018 study that used the GRACE satellites to show that ice gains in East Antarctica haven't kept up with ice losses in the west, and that melting ice has added nearly 3 trillion gallons of water to the oceans over the course of 25 years.

Sinu toodud viited on huvitavad just selle tõttu, et minu jaoks pigem tõestavad argumentide vähesust

Nasa kirjutab üldisest Antarktika jääst (net gain), kuid antud allikates on kirjas kirjutatud mingite konkreetsete piirkondade jääst.

We map present-day Antarctic-wide surface velocities using Landsat 7 and 8 imagery spanning 2013–2015 and compare to earlier es-timates derived from synthetic aperture radar, revealing heterogeneous changes in ice flow since ∼2008.
