Arctic Ice Marching 2019

Science Matters

A previous post discussed 15M km2 as the average maximum threshold for March arctic ice extents.The graph shows 2019 exceeded the previous two years, but now it appears to fall just short.  On day 61, March 2, 2016 peaked well above 15M, and did not reach that level again. The graph shows 2017 peaked early and then descended into the Spring melt.  2018 started much lower, gained steadily before peaking on day 74, 250k km2 below average. 2019 has been exceptional, surging early to surpass average on day 54, then declined for a week, before re-surging to virtually tie the average extent on day 70.  Day 71 extent matched the earlier peak, then retreated and is now unlikely to go higher after day 75.

Presently, on day 75 2019 is 1% below the 12 year average (2007 to 2018 inclusive) and slightly higher than the preceding three years.

Carbon Dioxide–The bringer of life

Comment from Watts Up With That:

The early Earth’s atmosphere contained no free Oxygen and 10000ppm+ CO2 and the Earth did not become like Venus even when all the carbon was to be found in the atmosphere.
Early life on Earth was blue green algae which thrived in this CO2 rich atmosphere – liberating vast quantities of Oxygen.

Note: Free Oxygen does not exist on planets as it is highly reactive and forms metal oxides which sequestrate it into solid carbonates and oxides – so much so that cosmologists searching for exoplanets [planets outside of our solar system] look specifically for the tell-tale spectrographic signature of Oxygen as an indication of life existing on those planets – thus far nothing has shown up.

This oxygen made the air toxic to the algae – remnants of such species can be found in the class of “anerobic” organisms.

New species evolved to use the oxygen which also allowed more energy intensive biology – eventually leading us to where we are today.

So the first successful species were the megaflora – so successful they “polluted” their atmosphere with Oxygen and were extinguished at the end of the Carboniferous period – which laid down the Carbon that is the basis of all today’s fossil fuels.

The Oxygen rich (±30%) atmosphere gave rise to the mega fauna – Dinosaurs and such – have you ever noticed that dinosaurs have relatively small chests ? If we brought a T-Rex into being (A’La Jurassic Park) it would stand there wheezing – gasping for breath in our Oxygen depleted atmosphere.

You should also note there is a symbiotic relationship between volcanic action and the Earth’s carbon based life forms (that’s you, me and most every living thing). Without volcanic CO2, all the Carbon would eventually become sequestered into limestone and life as we know it would slowly come to an end. Life on Earth requires volcanic and tectonic action to “reprocess” the sequestered CO2 In the rocks and release it back into the atmosphere.

CO2 is essential to life on our planet – it does not “control” the climate in any significant way.

Prior to the industrial revolution, CO2 was spiralling dangerously downwards. Our production of CO2 is saving the planet not destroying it !

Man is responsible for all manner of hideous crimes against the environment – CO2 just simply isn’t one of them.

The unscientific distraction of the Global Warming / CO2 phantasm is diverting attention, funds, resources and scientific examination of these very real problems. This willful neglect will be viewed by future generations as one of the most damaging of acts or omissions ever inflicted by humankind on the environment.

NOAA: ‘Incredible’ amounts of snow in California’s snowpack — Flood?

Sierra Foothill Commentary


It was a similar snowpack in the winter of 1861 – 1862 that as melted by an atmospheric river of warm rain that pelted the state for a month melting the snow, which flooded the valley, with the flood water rising to the second floor of the homes and building in Sacramento.

One description of the impact of the flood;

The event was climaxed by a warmer, more intense storm with much more rain that was much more serious, due to the earlier large accumulation of snow, now melted by the large turbulent heat fluxes into the snow over the lower elevations of the mountains. Throughout the affected area, all the streams and rivers rose to great heights, flooded the valleys, inundated or swept away towns, mills, dams, flumes, houses, fences, and domestic animals, and ruined fields. An early estimate of property damage was $10,000,000. However, later it was estimated…

I’m Not Predicting That Arctic Minimum For 2019 Has Occured on Day 70 – 2019

sunshine hours

I’m not predicting that Arctic had reached maximum for 2019 on 70 (because that didn’t work out so well for Antarctica.

But if it had reached max it was the 8th lowest.

Not much of a climate emergency.

What are the opponents of Donald Trump’s climate review committee afraid of?

“It’s time for the science of climate change to be independently reviewed by a body whose members do not depend upon climate alarmism to sustain their careers.”
– Dr. Roy Spencer

Tallbloke's Talkshop

Dr Roy Spencer tries to strike a note of sanity amidst the latest bout of doom-laden climate hysteria doing the rounds via cynical manipulation of the minds of school kids. What is accelerating is the bluster of alarmists, who lack credible empirical evidence of ‘human-caused’ as opposed to natural climate variation.

On March 5, 58 senior military and national security leaders sent a letter to President Trump denouncing his plan to form a National Security Council panel to take a critical look at the science underpinning climate change claims.

Their objections to such a Red Team effort were basically that the “science is settled”, writes Roy Spencer in The Washington Times.

But if the science is settled, what are they afraid of? Wouldn’t a review of the science come to the same conclusion as the supposed consensus of climate scientists?

BBC’s Climate Lies Becoming A Habit


By Paul Homewood

As I revealed yesterday, the BBC has formally upheld my complaint about their African penguin story. I am pleased to see then that The Times has now picked it up.

This complaint is now the eighth climate-related one I have been involved with which has been upheld against the BBC in the last two years. There may of course be others that I am not aware of.

The Sky’s Not Falling

Sierra Foothill Commentary

By Congressman Tom McClintock

Abraham Lincoln told the story of boarding with the family of a Presbyterian minister on the night of the greatest meteor shower ever recorded in North America.  He was awakened by the minister who shouted, “Arise, Abraham, for the heavens are falling and the day of judgment has arrived.”  But Lincoln noticed that despite the hysteria around him and the chaos above him, he could still see the familiar constellations fixed in the sky, and he knew the world was not about to end.

No one denies that our planet is warming, carbon dioxide levels are increasing, and ocean levels are rising.  But before we run screaming into the night, let’s also do a quick reality check.  The sky isn’t falling. 

Global warming (and cooling) is nothing new: our planet has been warming on and off since the last ice age. There…
