Why Worry about Warming? Cold is the Killer
Green alarmists are fanning a firestorm of fear about man-made global warming. Earth always cycles between warmth and cold. Every recent warm period (Medieval Warming, Roman Warming etc) was a time of plenty for all life on Earth, whilst cold periods like the Little Ice Age saw crop failures, famine, migrations, invasions, disease and death.
Sea levels rise as ice sheets melt, and fall as they rebuild. Coastal dwellers and offshore coral reefs must always migrate landward or seaward, or north/south, following the climatic environment they prefer.
Warming/cooling phases are triggered by solar system cycles which are often accompanied by volcanism. These drivers are far more powerful than any human influences.
Oceans cover over 70% of Earth’s surface and dominate our weather and climate. When the sun or the volcanic trenches and the rings-of-fire warm the oceans, two things happen. Firstly, water evaporates to form more clouds which shade, cool and rain on the Earth. Secondly, CO2 plant food is expelled into the atmosphere, like CO2 bubbles leaving a warming beer. This makes the oceans more alkaline.
With the additional moisture and CO2 plant food in the atmosphere, all plants benefit – forests expand, deserts shrink and grasslands, crops and marine plants flourish. All animals that live on plants or on grazing animals are also well fed. Soon farmers, graziers, foresters, fishermen, city dwellers and tax collectors welcome better times.
But climate is never still – changing climate and variable weather are normal conditions on Earth. For the last million years, Earth has basked in recurring short Warm Periods (about 12,000 years) followed by long brutal Frigid Periods (about 80,000 years).
Evidence from the Greenland Ice Cores shows that Earth’s 1000 year average temperature peaked about 7,500 years ago and has been trending down for over 3,000 years. There are always short term fluctuations but we are past the warming peak. We live now in the latter days of the Holocene Warm Period. There may be short bursts of warming, but the big trend is down. A frigid period lies ahead.
As cyclic solar heating declines, land cools quicker than the deep oceans. Moisture will still evaporate from the warm oceans and fall on the cooling land as rain and snow. Snow and ice will again advance over the northern grain belts. Continued evaporation soon triggers cooling of the oceans which then re-absorb atmospheric moisture and CO2.
Plants always suffer greatly in the developing cold, dry, CO2-starved atmosphere. And when plants suffer, animals and humans face hunger and famine.
Industries and cities powered by coal, oil, gas and nuclear power are largely immune to changing climate. However we are making a huge climate gamble by demonising reliable hydro-carbons and nuclear power and rushing into intermittent, climate-dependent energy such as wind and solar propped up by “humungous batteries”.
The Holocene Warming is almost over. After today’s bountiful warmth comes the cold, dry, hungry phase of Earth’s climate. Fruitful warmth is no threat. Bitter cold is the deadly menace.

I have never seen any mention of the average temperature peaking 7500 years ago. Some supporting evidence from the Greenland ice cores would be helpful.

Hi Alan,
You wrote: “I have never seen any mention of the average temperature peaking 7500 years ago.”
Review the history which I believe you know. It seems to have been accepted that glaciers covered northern portions of the northern hemisphere’s continents a little south of 45 degrees N little more than 10,000 years ago. And it seems we know about the ‘little ice age’ which was observed a little less than 10,000 years ago. So, in between the great glaciers more than 10,000 years ago and the little ice age there had to have been a significant warming which melted those glaciers which existed little more than 10,000 years ago.
Relative to the focus on the little ice age I have read about rivers freezing over in the British Isles. What I have not commonly read much about is the abnormal ‘normal’ weather (climate) of Iceland For the normal climate we expect for Iceland because of its ‘northerly’ latitude is that of the little ice age.
Of course, we understand that this abnormal normal climate of Iceland is due to the ‘Gulf Stream’; which I do not describe because it is so well known. And I expect that many believe it is also well explained.
To keep this comment relatively brief, I merely state: I believe that we will really understand the abnormal normal weather (climate) of Iceland when we can predict (with reasonable accuracy) El Nino—La Nina events. For we must try to better understand the winds of the Earth.
Have a good day, Jerry

Have to correct what I did not intend to write.
What I intended was ‘the ‘little ice age’ which was observed a less than 1,000 years ago.’

Yes Andy. Viv Forbes was the first writer I saw include moon cycles as having influence in climate.

Good to read the tax collectors doing well.

I cannot understand the idea put forward that global warming is bad. Co2 is food for plants and help to provide food for animal life. Co2 is heavier than air and so will not prevent heat from leaving the earth. I agree that cold and not warming is the big problem.
