California Climate Roller Coaster

It contradicts claims often made by global warming alarmists that the perceived California climate change is unusual, and that it is mostly due to man emitting “climate gases” into the atmosphere.
The new study finds that California’s climate has always been extreme roller coaster-like – even when atmospheric CO2 was at very low levels (ca. 200 ppm), as was the case during the last ice age. Proxy evidence shows “temperatures varied during the last glacial, including extreme warmth”.

What follows is the paper’s abstract:

Reconstructions of past hydroclimate provide a means to understand precipitation responses to global ocean-atmosphere climate dynamics beyond the scope of that in the instrumental record. Late glacial climate was characterized by abrupt variability in ice and ocean dynamics, however the implications for hydroclimate are not as well known. Here we present organic geochemical proxy evidence for precipitation isotopes based on plant leaf wax hydrogen isotopic compositions (δDwax) and temperature proxy evidence based upon the branched glycerol dialkyl glycerol tetraethers (brGDGTs), that derive from the membrane lipids of bacteria, each extracted from a sedimentary archive in Lake Elsinore, California spanning 32–9 ka. We add proxy evidence for vegetation and salinity from additional biomarker analyses and compare to prior pollen and sedimentological evidence from the same core. Our record indicates a strong deglacial warming of 10 °C in Lake Elsinore (beginning at 14.5 ka) that accompanied a D-enrichment of precipitation of +90‰ and more C4vegetation (12–10 ka), after a cold, wet and C3-dominated phase (20–14.5 ka), indicating winter-dominated precipitation during the Last Glacial Maximum and Heinrich Stadial 1. During the late glacial (32–20 ka) we find abrupt variability, with precipitation isotopic shifts (∼70‰) that are independent of temperature swings implicating changes in storm track, rather than local temperature as drivers of the precipitation isotope signal.Temperature is however not irrelevant for hydroclimate: we find extreme warmth at 29.4 ka and 26.8 ka, the latter coincident with existing reports of an extended dry period (27.5–25.5 ka), suggesting a long hot and dry interlude during the generally cooler glacial period. We compare δDwax with speleothem δ18O from Nevada, also within the winter-dominated precipitation region. Our results corroborate the Last Glacial Maximum and deglacial signals, and fill gaps revealing storm-track instability from 32–20 ka,however the pacing and magnitude of the biomarker signals merit cautious interpretation.”

Surprise, surprise – California’s climate has always been on the very wild side. Low CO2 did not tame it at all.

Oh No!

WASHINGTON — A major Greenland glacier that was one of the fastest shrinking ice and snow masses on Earth is growing again, a new NASA study finds.

The Jakobshavn (YA-cob-shawv-en) glacier around 2012 was retreating about 1.8 miles (3 kilometers) and thinning nearly 130 feet (almost 40 meters) annually. But it started growing again at about the same rate in the past two years, according to a study in Monday’s Nature Geoscience. Study authors and outside scientists think this is temporary.

“That was kind of a surprise. We kind of got used to a runaway system,” said Geological Survey of Denmark and Greenland ice and climate scientist Jason Box. “The good news is that it’s a reminder that it’s not necessarily going that fast. But it is going.”

Box, who wasn’t part of the study, said Jakobshavn is “arguably the most important Greenland glacier because it discharges the most ice in the northern hemisphere. For all of Greenland, it is king.”

The Greenhouse Effect Refresher

Atmospheric Gases: When discussing atmospheric gases, it is useful to refresh one’s memory of the relative concentrations of various gases. To be more useful these will be put in the same units, that is ppmv: parts per million by volume. In the idealized dry atmosphere:

Nitrogen is about 78% of the atmosphere or 780,840 ppmv;

Oxygen is 20.9% or 209,460 ppmv;

Argon is 0.93% of the atmosphere or 9,340 ppmv;

Carbon dioxide is about 0.04% of the atmosphere or 400 ppmv [carbon dioxide varies seasonally and is increasing]. The next greenhouse gas, significantly lower, is

Methane, with about 0.00018% of the atmosphere or 1.79 ppmv;

Nitrous oxide is about 0.0000325% or 0.325 ppmv; and

Ozone is about 0 to 0.000007% or 0 to 0.07 ppmv.

The greenhouse influence of ozone is predominantly in the upper the atmosphere, the stratosphere, where it is created naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules. It is formed elsewhere in the atmosphere with chemical reactions involving volatile hydrocarbons, oxides of nitrogen, and sunlight. Before pollution control devices, ozone from car exhausts were a problem. In eastern forests of North America, terpenes from trees can create ozone haze under the proper conditions.

Methane and nitrous oxide do not have enough concentration to increase the greenhouse effect significantly.

The kicker to this is water vapor, H2O in a gaseous phase. Over the full atmosphere, it is calculated to be about 0.4% or 4,000 ppmv. In the troposphere water vapor is typically 1% to 4% or 10,000 to 40,000 ppmv. The boundary between the troposphere and stratosphere is called the tropopause. From the NCAR/UCAR web site:

“The troposphere is the lowest layer of Earth’s atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere is by far the wettest layer of the atmosphere; all of the layers above contain very little moisture.

“The bottom of the troposphere is at Earth’s surface. The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer). It can be as high as 20 km (12 miles or 65,000 feet) near the equator, and as low as 7 km (4 miles or 23,000 feet) over the poles in winter.”

By the tropopause, liquid water and water vapor freeze out and above it, the concentration is only about 4 ppm. See: https://scied.ucar.edu/shortcontent/troposphere-overview

H/T to SEPP

CO2 is not the earth’s temperature control knob, it is water vapor. The major source of water vapor is the planet’s oceans, which are warmed by the sun. A warm Pacific produces more water vapor and more rain, cooler Pacific ocean produces less water vapor and more drought. It is a process that has been going on since the oceans were created.  The more water vapor in the air, the more heat it can hold, the same is not true of CO2.  Water vapor, not CO2 is is the temperature control knob for the planet, the problem is Mother Nature is the only one with access.

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

ca-snowpack-totals

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 that approximately one-quarter of the taxable real estate in the state of California was destroyed in the flood. Dependent on property taxes, the State of California went bankrupt. The governor, state legislature, and state employees were not paid for a year and a half. 200,000 cattle drowned, and the state’s economy shifted from ranching to farming.

Bottom line, with a super snowpack in place and the potential for warm spring rains, we could have another mega flood. Watch the weather reports for atmospheric rivers of warm rain.

The Sky’s Not Falling

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 have been periods throughout both recorded history and pre-history when scientists tell us temperatures were much hotter (and colder) than they are today.   Science tells us that carbon dioxide levels have varied widely throughout the planet’s history, and have often been many times higher than today.  Science tells us that at the end of the last ice age, ocean levels were 400 feet lower than they are today and the modern rise has been steady, small, and doesn’t correlate to carbon dioxide levels.  In the Caribbean, where continuous hurricane records date back to 1690, hurricane frequency dropped 20 percent in the last century. 

And despite what we are told, there is a vigorous debate within the scientific community over how much human activity influences climate compared with vastly more powerful natural forces that have driven climate change for 4 ½ billion years.  As Chicken Little belatedly discovered, there is a big difference between an acorn and the sky.

I agree the sky is not falling, humans cannot control the climate by twisting the CO2 control knob, it is a natural cycle, which will turn to the cool side in due time.
