Rainforests Near The South Pole And Summers 38°C Warmer Than Today During The Age Of Dinosaurs

Fossilized evidence of temperate rainforests only hundreds of kilometers from Antarctica’s South Pole (82°S) has been uncovered. It suggests the warmest mean month was 18.5°C about 90 million years ago. Today the warmest mean month for this location is about -20°C. Image Source: EarthSky (press release for Klages et al., 2020) Despite rapidly rising CO2 […]

How melting glaciers have accelerated a shift in Earth’s axis

The redistribution of water has caused the planet to lean and wobble, resulting in the poles moving The axis of the Earth has shifted and moved the locations of the north and south poles. The poles have always wandered very gradually on the globe but in 1995 the north pole turned away from Canada towards […]

Tree Remains Found Buried Beneath Today’s Glaciers Date To The Warmer-Than-Today Medieval Warm Period

A new study (Kullman, 2021) suggests ~9000-year-old tree remains can be found buried in “currently empty snow hollows and glacier cirques” at elevations 600-700 m higher than where trees can grow today, implying a >3°C warmer Early Holocene climate. Treelines were still 75-100 m higher during the Medieval Warm Period…and even during the 15th and […]

March Sea Ice: Arctic Stable 16 Years, Gains 504,000 Sq Km Since 2017! Antarctic Above Mean!

Though it has dropped since its peak in 1979, Arctic sea ice extent in March has remained stable since 2005. There are two months that are of particular interest in the Arctic: September, when sea ice reaches its minimum, and March, when it reaches its maximum. Gains 504,000 sq km. Today we look at Arctic […]

New Study Suggests Southwest Greenland Was 6-7°C Warmer Than Today 9,000-5,500 Years Ago

Scientists have determined the “optimal thermal conditions” for southwestern Greenland were when summer sea surface temperatures averaged about 12°C from 9,000 to 5,500 years ago, which is substantially warmer than modern summer temperatures (4.0-5.2°C) for this region. A few years ago McFarlin et al. (2018) determined northwestern Greenland was 4-7°C warmer than 1952-2014 during the […]

New Study: 75% Of Recent Arctic Sea Ice Decline Is ‘Accounted For’ By An Internal Variability Pattern (PNA)

Scientists (Liu et al., 2021) have assessed the Pacific North American (PNA) pattern, “largely a mode of internal variability,” is “an important driver of western Arctic sea variability and trends”. The heat-redistributing PNA pattern recently shifted from a negative (1980s) to positive (1995-) phase. This internal shift “induced significant increases in poleward heat” transport, explaining […]

Stalled Warming: Global Mean Temperature Continues To Cool, Polar Sea Ice Stable At Normal Levels

Like January and February,March 2021 has so far been significantly colder than the same month last year. In the NCEP analysis up to 17 March 2021 and in the […]

Danish Institute Data: Greenland Ice Melt Has Slowed Down Significantly Over Past Decade

The media and activists, among them a number of “Climate scientists”, have been declaring that Greenland ice melt has been accelerating. Today the German Klimaschau climate news video reports, however, that this has not been the case over the recent years. All the recent talk about accelerating Greenland ice loss over the past years is […]

Alfred Wegener Institute Sea Ice Extent: “Both Polar Regions At NORMAL LEVELS”…Siberia 6-8°C Colder

Alfred Wegener Institute: Sea ice development in both polar regions at normal level Arctic On 31 January, 2021, the sea-ice extent in the Arctic was 14.29 million km², roughly the same level as in the previous two years. In terms of the long-term trend for the month, January 2021 comes in at 7th place with […]

New Study Finds A 79% Rise In Polar Bear Sightings Since 2005 As Their Arctic Habitat Dramatically Expands

Research on polar bear sightings using a systematic “regional marine mammal sightings programme” during 2005-2018 reveals there were 1,433 polar bears sightings from 2005-2011 compared to 2,569 during 2012-2018 around Svalbard. The perspective that polar bears  are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is  again contradicted by real-world observations. […]
