Graphing The Icy Reality

I post them up along with snippets of the stories. First, from the BBC: Greenland and Antarctica ice loss accelerating Earth’s great ice sheets, Greenland and Antarctica, are now losing mass six times faster than they were in the 1990s thanks to warming conditions. Next, from the NASA Jet Propulsion Laboratory (JPL) Basic Science: 4 Keys to Melt Fears About Ice Sheets Melting. William Ward, April 18, 2019 The world is drowning in articles about catastrophic sea level rise (SLR), reminding us that if the ice sheets melt, 260 feet of water will flood our coastal cities.

Basic Science: 4 Keys to Melt Fears About Ice Sheets Melting

We know that sea level today is 20-30 feet lower than it was at the end of the last interglacial period 120,000 years ago. We also know that sea level has risen 430 feet since the end of the last glacial maximum 22,000 years ago. Research shows this rise was not monotonic but oscillatory, and during periods over the past 10,000 years, sea level has been several meters higher than today. Polar Ice Surprises! Svalbard Well Over Average, Arctic Ice Remains Steady, Antarctic Ice Growing. By P Gosselin on 28.

Polar Ice Surprises! Svalbard Well Over Average, Arctic Ice Remains Steady, Antarctic Ice Growing

April 2020 Polar ice showing longer term stability. No basis for behind claims of a rapid melt. By Kirye and Pierre Gosselin We keep hearing how the ice at the poles is supposedly disappearing rapidly, yet a look at the latest data show this is not the case. Antarctic rebounding, trending upwards Antarctic ice has in fact trended upwards since satellite measurement began 40 years ago. Data: JMA. A brand new article here describes how “Antarctica is not rapidly melting.” The ice melt myth. According to the National Snow and Ice Data Center (nsidc.org), ice currently covers 6 million square miles, or one tenth the Land area on Earth, about the area of South America.

The Difference in Ice Types Causes Confusion in Global Warming Story

Tim Ball The central theme of purveyors of environmental and climate deception is to take normal events and present them as abnormal. Here are examples of the most frequently used stories involving ice in Antarctica. A 2017 New York Times (NYT) story titled “Miles of Ice ColIapsing into the Sea.” Or one from an agency that should know better but is among the worst for alarmist’s misinformation about ice. The recently released Fourth US National Climate Assessment is a broader example. Few know that ice forms and behaves in many different ways and causes a variety of effects in the atmosphere and on the land.

In 1768 William Wales and Joseph Dymond, appointed by the Astronomer Royal, Nevil Maskelyne, took a scientific expedition to Churchill, Manitoba to measure the Transit of Venus. 12 New Papers Affirm A 21st Century Cessation Of Arctic Warming And A Rapid Cooling Across Antarctica.

12 New Papers Affirm A 21st Century Cessation Of Arctic Warming And A Rapid Cooling Across Antarctica

April 2018 Since 2000s, An Arctic Warming & Sea Ice Pause … Cooling In Antarctica … Undermine AGW Claims It was 3 years ago when scientists first began documenting the pause in Arctic sea ice decline that began in 2007. While detailing the potential for “cherry-picking” such a short span of years to arrive at “misleading” conclusions, Swart et al. (2015) pointed out that there was a “near-zero” trend in sea ice extent during the brief 2007-2013 period. Swart et al., 2015. NASA: Natural Causes Behind Polar Melt. In what amounts to dissension from National Aeronautics and Space Administration (NASA) climate change policy, a series of just-released studies by working-level scientists prove that geological and not atmospheric forces are responsible for melting of Earth’s polar ice sheets.

Water Behaving Badly. Guest Post by Willis Eschenbach Those who know me are aware that I’m a tropical boy, a hopeless addict of warm blue seas and coconut-laden islands with white sand beaches.

Water Behaving Badly

Here’s where I used to live and work, Liapari Island in the Solomon Islands. That is how I like my water to behave, soft, warm, and inviting. But when the ice jumps out of my tropical-type adult beverage and starts running around the countryside covering everything in white and floating in giant chunks all over the ocean, well, I call that “water behaving badly”. And as you might imagine, other than brief visits I tend to avoid places where water behaves badly. However, thinking about such icy climes when I’m someplace warm, that’s a more pleasant matter. (As an aside, Figure 1 also shows the importance of starting by running the old Mark I Eyeball over your data before subjecting it to any mathematical gymnastics … but I digress.) The regular signal in the earlier parts of the record is an artifact.

Best to everyone, w.
