Global Sea Ice Area Data analyst Zoe Phin just posted some interesting, surprising results on global sea ice area. Data sources like the National Snow and Ice Data Center show global sea ice has been” drastically decreasing for a long time” and so we need to panic and overhaul the entire carbon economy. We hear this […]

The Greenland end-of-melt-season snowline should presumably be exhibiting a trend consistent with consequential Greenland ice sheet melt, especially an increase in the bare ice area. Yet, consistent with the recent non-warming trend for Greenland, there has been no statistically significant linear trend in these key climate change metrics. The Polar Portal Arctic tracking website includes […]

Paleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm). Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km². […]

By Kirye and Pierre Today we look at some important September trends at stations in the far north Atlantic and Arctic sea ice extent and volume. Al Gore’s doomsday predictions fade into old memories Greenland The September mean temperatures at the six stations in Greenland for which the Japan Meteorological Agency (JMA) has enough data are […]

Scientists continue to find regions of the world where modern “global” warming has not occurred. Sea surface temperatures (SSTs) in the South Atlantic (south of South Africa) and Southern Ocean (New Zealand) are colder today than they have been at any time in the last 12,500 years (Shuttleworth et al., 2021). SSTs were multiple degrees […]

The Canadian Arctic’s surface temperatures have been up to 15 to 25°C warmer than today during the geologically recent Holocene, Pleistocene, and Pliocene epochs. Scientists (Campbell-Heaton et al., 2021) assessing the ratio of winter temperature at the ground surface to that in the air (the “freezing n-factor”) suggest ground surface winter temperatures now (1981-2016) average […]

Norwegian data show September minimum Arctic sea ice has risen over the past 10 years, contradicting earlier predictions of a death spiral By Kirye and Pierre Friday NTZ posted on Arctic sea ice extent. This year Arctic sea ice has just about reached its minimum. and so we plot the new data (see below). Substantial […]

This year’s Arctic sea ice minimum reaches third highest level in a decade, latest data show. Die kalte Sonne here presents its latest climate video. The first part looks at this year’s Arctic sea ice melt season. Now that it’s September, sea ice extent has just about reached its minimum for the year and soon […]

In a “major revision” to the “long-standing view,” scientists are increasingly concluding the last glacial had summers “several degrees” warmer than today, with climate conditions warm enough to allow year-round grass grazing by horses, antelope, gazelle…in Siberia, Alaska, and north of the Arctic circle. Multiple degrees warmer glacial temperatures pervaded both hemispheres. The “long-standing view” […]

Exposed moss and willow shrubs buried beneath today’s receding East Greenland glaciers can be dated to 400 to 500 years ago, suggesting this period (the early Little Ice Age) was as-warm or warmer than today. It is widely accepted that Greenland’s surface temperatures were several degrees warmer (McFarlin et al., 2018, Axford et al., 2021) […]

A new study reports that during Pleistocene cold stages, when CO2 concentrations dipped below 200 ppm, Arctic Siberia had much more fertile soil and productive vegetation than exists today. Extensive grassland ecosystems could sustain year-round grazers: horses, mammoths, bison. Today this region’s large herbivores must be fed by humans to secure survival due to extremely […]

Sea ice has been declining in the Canadian North Atlantic since the 1970s, and yet the harp seal population has been estimated to have risen from a little over 1 million in 1971 to about 7.5 million in 2012 to 2019. But model projections suggest the seal populations will decrease in the future due to…declining […]
