This summer in SoCal has been one for the records with record high temps in a daily basis. The past 2-3, weeks where I live has never gotten under day time lows if 90 and soaring temperaturesqrfrff into the low 100‘s. Water shortages and strain on the electric grid is a daily occurrence We have been mandated to have 100% use of EV’s by 2035 but it gets crazy when we are told not to charge out EV’s because of the strain on the grid

However what really caught my eye yesterday when it was 108 where I live was the flollowing amazing statistic

And to think Steve there are those that don't believe in climate change ! Back in my area (Philly burbs) we have just come off the hottest August on record ! My lawn is crying for relief ! FWIW, I do understand meteorological records have only been kept since the Civil War.......

I found this to be a very interesting book. The author is someone I meet via my father years ago before he died. The author uses ice core, stalagmites, ancient tree rings, ocean floor seiments, coral fossils, satellite data, ancient written records etc to reveal a 1500 year heat and cool cycle that has gone on for millions of years across the planet. Its an interesting read.

BEV (battery electric vehicles) will not get us to zero ICE engines by 2035. the resources are not there for that to happen. Elon Musk agrees. need fossil fuels. unless the whole world works from home. but someone needs to build things and move things and fix things.

the rhetoric and legislative actions are pure politics. notice the absence of any big statements or push back by big oil. they have the most powerful lobby of any industry, and they are as quiet as a church mouse. even auto industry big wigs don't understand why big oil is so quiet.

the reason is big oil is quiet is that they will just sit back and allow the reality to take it's course, and they will just continue to do what they do. they know they cannot win in the court of public opinion. but.....they really don't have to. time is on their side.

you can't legislate tech breakthroughs. even Kennedy setting the moon landing goal only resulted in tech refinements of processes already on hand. cold fusion (flux capacitor) for the everyday auto will be needed to reach these lofty 100% use of EV's by 2035 projections. batteries won't cut it. and we will get man to Mars before we see cold fusion. it's easier.

It’s not just USA Steve, as much of Europe has seen record breaking temperatures this summer. This was in my mum’s garden in July; the same night saw a 29c low, which smashed the local record by some 5c! Sadly few homes here have aircon so there were many sleepless nights.

Antartica ice core sampling currently gives us an 800,000 year record of greenhouse concentrations in the atmosphere and a corresponding indicative record of global temperatures over most of the last millennium,

From the UK’s British Antarctic Survey…

Ice cores and climate change​


Ice cores are cylinders of ice drilled out of an ice sheet or glacier. Most ice core records come from Antarctica and Greenland, and the longest ice cores extend to 3km in depth. The oldest continuous ice core records to date extend 123,000 years in Greenland and 800,000 years in Antarctica. Ice cores contain information about past temperature, and about many other aspects of the environment. Crucially, the ice encloses small bubbles of air that contain a sample of the atmosphere – from these it is possible to measure directly the past concentration of atmospheric gases, including the major greenhouse gases: carbon dioxide, methane and nitrous oxide.

Greenhouse gases and the recent past​

Direct and continuous measurements of carbon dioxide (CO2) in the atmosphere extend back only to the 1950s. Ice core measurements allow us to extend this way back into the past. In Antarctic cores with a very high snowfall rate, it has been possible to measure concentrations in air from as recently as the 1980s that is already enclosed in bubbles within the ice. Comparison with measurements made directly from the atmospheric at research stations in Antarctica show that the ice core acts as a faithful recorder of atmospheric concentrations (see Fig. 1), although we do have to be cautious, as small artefacts can arise at sites with high concentrations of other impurities.
Chart, line chart

Antarctic ice cores show us that the concentration of CO2 was stable over the last millennium until the early 19th century. It then started to rise, and its concentration is now nearly 50% higher than it was before the industrial revolution (Fig. 2). Other measurements that can fingerprint the source of this CO2 (e.g. isotopic data) confirm that the increase must be due to emissions from fossil fuel usage and human-induced changes vegetation and soils. Measurements from older ice cores (discussed below) confirm that both the magnitude and rate of the recent increase are almost certainly unprecedented over the last 800,000 years (Fig. 2). The fastest natural increase measured in older ice cores is around 15ppm (parts per million) over about 200 years. For comparison, atmospheric CO2is now rising 15ppm every 6 years. Methane (CH4), another important greenhouse gas, also shows an unprecedented increase in concentration over the last two centuries. Its concentration is now much more than double its pre-industrial level. This is mainly due to emissions from agricultural sources and fossil fuel production, that comes on top of natural emissions from wetlands and other sources.

Natural climate change: glacial-interglacial cycles​

By measuring the ratios of different water isotopes in polar ice cores, we can determine how temperature in Antarctica and Greenland has changed in the past. The oldest continuous ice core we have was drilled by the European Project for Ice Coring in Antarctica (EPICA) from Dome C on the Antarctic plateau (Fig. 3). It extends back 800,000 years and shows a succession of long, cold ‘glacial’ periods, interspersed roughly every 100,000 years by warm ‘interglacial’ periods (of which the last 11,000 years is the most recent). This succession of events is well-known from other records, and the coldest periods in Antarctica are the times when we had ice ages. Ice sheets extended over North America as far south as places like Chicago and New York, and over Britain to south of The Wash.

The role of greenhouse gases in glacial-interglacial cycles​

From the air in our oldest Antarctic ice core, we can see that CO2 changed in a remarkably similar way to Antarctic climate, with low concentrations during cold times, and high concentrations during warm periods (see Fig. 3). This is entirely consistent with the idea that temperature and CO2 are intimately linked, and each acts to amplify changes in the other (what we call a positive feedback). It is believed that the warmings out of glacial periods are paced by changes in Earth’s orbit around the Sun, but these small changes in climate are amplified, mainly by the resulting increase in CO2, and by the retreat of sea ice and ice sheets (which leads to less sunlight being reflected away).
We can see how remarkably closely Antarctic temperature and CO2 tracked each other, but what about global temperature? Here we can examine the last time the earth emerged from an ice age. Scientists have compiled other geologic records of temperature from around the world to calculate the average global temperature. On this global-scale, CO2 starts increasing before temperature (see Fig. 4.) (Shakun/Osman), thus temperatures are said to “lag” behind CO2. This demonstrates that CO2 was not only a feedback on natural climate change but in fact major forcing that drove the earth out the last ice age.
In our modern era, of course, it is human emissions of CO2 that are expected to kick-start the sequence of events. We see no examples in the ice core record of a major increase in CO2 that was not accompanied by an increase in temperature. Methane concentration also tracks the glacial-interglacial changes, probably because there were less wetlands in the colder, drier glacial periods.

Abrupt climate change​

The climate changes described above were huge, but relatively gradual. However, ice cores have provided us with evidence that abrupt changes are also possible. During the last glacial period, Greenland experienced a sequence of very fast warmings (see Fig. 5). The temperature increased by more than 10°C within a few decades. Other records show us that major changes in atmospheric circulation and climate were experienced all around the northern hemisphere. Antarctica and the Southern Ocean experienced a different pattern, consistent with the idea that these rapid jumps were caused by sudden changes in the transport of heat in the ocean. At this time, there was a huge ice sheet (the Laurentide) over northern North America. Most likely, freshwater delivered from the ice sheet to the North Atlantic periodically disrupted the overturning of the ocean, causing the transport of tropical heat to the north to reduce and then suddenly increase again. While this mechanism is unlikely to occur today’s world, it does show us that, at least regionally, the climate is capable of extraordinary changes within a human lifetime – rapid switches we certainly want to avoid experiencing.


Ice cores provide direct information about how greenhouse gas concentrations have changed in the past, and they also provide direct evidence that the climate can change abruptly under some circumstances. However, they provide no direct analogue for the future because the ice core era contains no periods with concentrations of CO2comparable to those of the next century.
