Justin Gillis answer to Question 4. What’s the optimistic scenario?

“Several things have to break our way.

In the best case that scientists can imagine, several things happen: Earth turns out to be less sensitive to greenhouse gases than currently believed; plants and animals manage to adapt to the changes that have already become inevitable; human society develops much greater political will to bring emissions under control; and major technological breakthroughs occur that help society both to limit emissions and to adjust to climate change.

The two human-influenced variables are not entirely independent, of course: Technological breakthroughs that make clean energy cheaper than fossil fuels would also make it easier to develop the political will for rapid action.

Scientists say the odds of all these things breaking our way are not very high, unfortunately. The Earth could just as easily turn out to be more sensitive to greenhouse gases than less. Global warming seems to be causing chaos in parts of the natural world already, and that seems likely to get worse, not better. So in the view of the experts, simply banking on a rosy scenario without any real plan would be dangerous. They believe the only way to limit the risks is to limit emissions.”

My answer to Question 4. What’s the optimistic scenario?

We are now in a sweet spot as to climate, not too warm and no ice age yet. Were it not for increasing CO2 levels the little ice age might have triggered the onset of a real ice age, but a lot of factors, such as coming out of the Maunder solar minimum, starting industrialization in England and Germany sooting up the growing glaciers so they started melting again, the diminishing effect from the Tycho Brahe and Kepler supernovas cosmic radiation, all contributed to get us out of the start of the new ice age. Yet, we are into the latter stages of the bog generating phase of the interglacial period, and the onset of a new ice age is overdue.

We need more CO2, not less to keep us in the climate sweet spot. Increasing CO2 levels to between 850 and 1000 ppm should delay the onset by about 2000 to 5000 years (my guess), but after that the next ice age is coming. Historically, according to the Milankovitch cycles we should have already entered the next ice age.

This picture is simplified, but together with the other cycles the picture is quite complicated.

The take home from this picture is that daily insolation (at the 60th latitude) can vary by as much as 100 w/m2 or about 50 times the effect of a doubling of the CO2 level. It is also worth noting that the normal state of the earth is ice age, and thermal runaways have never occurred, even when in past geological ages, CO2 levels were over 10000 ppm.

 

 

Snow in Sahara before Christmas! A Limerick.

saharasnowIt snowed in Sahara last night!

Ain Sefra’s, Algeria delight.

It did last for a day.

Cold. What more can I say?

A wrench in the Climate Change fight.

It is the first time since February 1979 it has snowed in Ain Sefra, located on the edge of the Sahara Desert. That snow lasted for about an hour, and it was mid-winter. This time the snow lasted for a whole day, and it was on the last day of fall!

I guess this is why the alarmists changed from calling it Global Warming to Climate change. Snow that lies doesn’t lie.

It is getting cold.

Look at the snow cover!

Polar Ocean Challenge in trouble. Too much Arctic ice.

svalbard-day2-16th-0924-2On June 19th 2016, the Polar Ocean Challenge expedition left Bristol in the boat Northabout to circumnavigate the North Pole anticlockwise. By doing this they hoped to demonstrate that the Arctic sea ice coverage shrinks back so far now in the summer months that sea that was permanently locked up now can allow passage through.

Permanent irreversible change in the sea ice landscape of the Arctic seems to them inevitable. This will / is already having global economic political, social and environmental implications. The goal seems lofty and idealistic enough.

There is only one major problem. The Arctic Ice Cap isn’t cooperating. Let us take a look at the polar ice cap on Aug 6, 2015.

CICE_combine_thick_SM_EN_20150806 The North East Passage  was open for clear sailing the whole Russian coastline and they planned to go through the North East Passage ice choke point, Cape Chelyuskin on or about Aug 5. 2016. It is now Aug 8, and the boat is huddling in a sheltered cove waiting for the ice to melt. Taking a look at the Arctic ice cap for Aug 6, 2016.FullSize_CICE_combine_thick_SM_EN_20160806There seems to be a lot of melting left to be done before they can pass through the choke point.

How bad is it? The total Arctic ice volume on Aug 6 last year was around 6250 cubic kilometre. This year the volume on Aug 6 was about 8000  km3, a year to year increase of about 28%. The  ice volume is now very close to the 30 year average.

Reality has a way of getting in the way of the best laid plans and the most ambitious climate models.

If you want to follow the future adventures of the ship Northabout, their website is http://polarocean.co.uk/calendar/

Update: Looking at the tracker, Northabout seems to have passed Cape Cherlyuskin the afternoon of Aug 9, only 4 days behind schedule. They should be able to sail another 50 miles or so before hitting heavy pack ice.

Verse 83 of the Obama Impeachment song: Global Warming drives us crazy.

obama-mentally-illHere is the link: https://www.whitehouse.gov/the-press-office/2016/04/04/fact-sheet-what-climate-change-means-your-health-and-family

The White House claims are alarmism at its worst, mostly complete nonsense.

On Obama’s visit to Cuba, he said in the joint press conference with Raúl Castro:

Our governments will (…) work together to protect the beautiful waters of this region that we share. And as two countries threatened by climate change, I believe we can work together to protect communities and our low-lying coasts.”

This brings us to verse 83 of the Obama Impeachment song (as if sung by President Barack Hussein Obama to the tune of “Please release me, let me go”)

Global Warming drives me mad

I said to Castro, my comrade.

Common sense is gone, too bad.

I can only say: You have been had.

Here is the complete impeachment song: https://lenbilen.com/2015/02/25/the-complete-obama-impeachment-song/

Obama on leadership, COP21, the pause, warmest year on record, the facts.

Asking Obama about his comments a year ago that America is the indispensable nation and that America leads, CBS 60 minutes interviewer Steve Kroft commented that Vladimir Putin “seems to be challenging that leadership” with his actions in Syria.

Obama’s response was revealing about how he sees the role of the United States as a global leader. “If you think that running your economy into the ground and having to send troops in in order to prop up your only ally is leadership, then we’ve got a different definition of leadership,” Obama replied. “My definition of leadership would be leading on climate change, an international accord that potentially we’ll get in Paris. My definition of leadership is mobilizing the entire world community to make sure that Iran doesn’t get a nuclear weapon. And with respect to the Middle East, we’ve got a 60-country coalition that isn’t suddenly lining up around Russia’s strategy.”

Leadership? Obama seems to have an unique angle on leadership. He claimed in his  April 18 weekly address to the nation, : “2014 was the planet’s warmest year on record.”

This will be one of his main arguments going into the Climate Conference COP21 in Paris in December.

How accurate is this statement?

Besides from the fact that we are not even close to the Minoan warming period 3000 years ago, or the Roman warming period 2000 years ago, not even the Medieval warming period 1000 years ago it is way off the mark on other facts as well. The figure below is from the Greenland Ice Core probings and is one of the best gauges for temperature records the last 10000 years. 2014 was still one of the 1000 coldest. Note also that the inter-glacial maximum temperature was around 6000 years ago and we are well into the bog-building face where normally Carbon would be deposited in the bogs and trigger the next ice-age. Burning Coal slows down the cool-down.

We are now experiencing an 18 year 8 month pause in the warming occurring since the little ice age. This is an undisputed fact if one looks at the satellite data.

18yr8monthspauseHowever, if one looks at the data generated by the surface stations it looks quite different. There has been a substantial rise in global temperatures since measurements began, and indeed, this century is so far the warmest on record.

ncdc.global.history.0910So, who is right? The official satellite measurements or the official surface temperature measurements?

The satellite measurements are done without any corrections, but the instruments are frequently calibrated to ensure no temperature drifts occur over time.

On the other hand, the United states Historical Climatology Network (USHCN) is the custodian of temperature data from the 48 contiguous states. As temperature stations are dropped and others are added they try to do a homogenization step to present the most probable past temperatures for the 48 states. This leads to temperature adjustments to past readings. They sincerely try to do the best job possible to ensure the adjustments are without bias of any kind. If we look at the next picture they did a near perfect temperature adjustment of past temperatures as a linear function of CO2 concentration.

tempC02(Credit to Tom Heller who did the analysis). This means that all homogenization was performed assuming the temperature adjustments had to conform to the IPCC model.

In other words, by assuming the model is right you adjust the data until they fit the model. Using the adjusted data you then claim this proves the model is right.

Climate science?

Global warming? Ice-breaker rerouted to Hudson Bay to assist commercial ships rather than doing research on global warming. A Limerick.

Irony of ironies:

CCGS Amundsen re-routed to Hudson Bay to help with heavy ice

Worst ice conditions in 20 years force change of plans to icebreaker research program

CBC News Posted: Jul 22, 2015 6:56 AM CT

CCGS_Amundsen_in_the_Arctic

Instead of the North Baffin Bay

the Amundsen did turn away.

“Too much ice in July,

all our models awry.”

Must break Ice down in Hudson’s ice bay.

A carefully planned, 115-day scientific expedition on board the floating research vessel, the CCGS Amundsen, has been derailed as the icebreaker was called to help resupply ships navigate heavy ice in Hudson Bay.

“Obviously it has a large impact on us,” says Martin Fortier, executive director of ArcticNet, which coordinates research on the vessel. “It’s a frustrating situation.”

During the summer, the  Amundsen operates as a floating research center studying climate change with experiments running 24 hours a day. This year it was scheduled to reach North Baffin Bay.

This is the slowest melt of the Hudson Bay ice in many, many years.

And the melt season is rapidly ending. All Ice Ages start in the Hudson Bay region, not the North Pole.

Update: Ice on Hudson Bay still there on Aug 5:CMMBCTCA2

The U.S. economy shrank by 0.7% in first quarter due to lack of Global Warming. A Limerick.

The U.S. economy shrank by 0.7 in the first quarter of 2015 as harsh weather dampened consumer spending and energy companies struggling with low prices slashed spending.

Gross domestic product contracted at a 0.7% percent annual rate, the Commerce Department said Thursday, coming dangerously close to a recession.  That was a big step down from the fourth quarter’s 2.2 percent rise and does not bode well for the rest of the year.

This winter’s cold Climate Disruption

has caused a big growth interruption.

When it’s warm it is good

makes the plants grow more food.

This CO2 scare: Just corruption.

CO2 concentration has increased from about 280 ppm in pre-industrial times to over 400 ppm today, and is increasing at a rate of 2 ppm per year. We are way past the point of no return, 350 ppm which would lead to a temperature catastrophe. But instead, something rather interesting is occurring. The earth is getting greener! This 40 % increase in CO2 the last 250 years has led to a more than 30 % increase in agricultural production all by itself without adding fertilizer or using higher yielding seeds. Thanks to this we can now feed an additional two billion people on earth without starvation. The news are so good, that the per capita food production is increasing, even as the population is increasing.

Look at it this way. The value of basic agricultural products is more than 1.5 trillion dollars worldwide. 30% of that is due to increased CO2. That means that the CO2 emitted is worth 450 billion dollars, spread out over all farmers and ranchers worldwide. This wealth transfer is occurring right now, and knows no national boundary. It is a gift from the developed countries to the rest of the world. Who could be against that?

It turns out that this wealth transfer occurs without global governance. The leaders of the world will not have their say in who gets the wealth transfer, the U.N. bureaucrats will not get their cut, and politicians cannot get a campaign issue since it occurs without their involvement.
