It’s time for the annual Earth Day

to celebrate Lenin’s old birthday.

CO2, it is clean

Makes more food, makes it green.

Rejoice! Let us have a green mirth Day!

We are called to take care of ourselves, be good stewards of the Earth, and strive to leave it a better place than we entered it.

To do a good clean-up job takes a lot of energy. That is true for the whole Eco-system as well as the toilet bowl.

All our energy comes from the Sun in one way or another, except for nuclear energy. If the cosmic radiation changes, or the total energy output from the sun changes, or our polar orbit and attitude changes, all of these factors will lead to climate change. 95 percent of the time the earth is in an ice-age, interrupted by short warm periods. We are now at the bog-building phase of an interglacial period, which means, the next phase is another ice-age.

This warm period is unique since we are experiencing rapidly increasing levels of CO2. Will that cause a rise in temperatures rendering the earth uninhabitable, or will it prolong the warm period, or – will it hasten the arrival of the next ice-age?

According to 75 out of 77 ( the origin of the “97% of all”…. ) Climate Scientists that in the previous 5 years had published multiple, peer reviewed papers, paid for by their respective academic institutions, which in turn was paid for mostly by their governments, claim “The science is settled”, and we will experience a rapid climate change, rendering parts of the world uninhabitable, and a series of other calamities will befall us unless we take strong, immediate action to reduce the output of CO2 from burning fossil fuels.

But there are in excess of 30,000 other scientists that have signed up “Science is by no means settled” and CO2 is not a pollutant, but a life giving gas that is only a minor contributor to the temperature rise. Other factors are at least as important and we should concentrate on real pollution, clean air and clean water.

So, who is right?

The last ice age had lasted for over 50,000 years. The ice stretched over most of North America down to the Finger Lakes. Western Europe down to Mid Germany and extending into Western Siberia were also under heavy ice. For some reason Eastern Siberia and Western Alaska was not under heavy ice. The sea level was about 400 feet lower than today and then suddenly temperatures rose, and after a 300 to 500 years delay C02 levels rose from about 185 ppm, barely sustaining life up to about 280 ppm, after which CO2 levels stabilized and remained in a slight decline until recently.

I grew and went to school in Sweden. At that time the way Sweden exited the Ice age was taught in all schools, the signs from the ice age were everywhere. We learned the exit from the exit could be expressed with the acrostic BYAL, signifying four phases in the deglaciation. Here is the timeline (after the pictures of the Baltic)

10,000 years ago: The Baltic ice lake. Outflow through Oresund, Rapid ice melt, temperature about the same as today, CO2 280 ppm.

9000 years ago: The Yoldia Sea. As ice recedes, salt water enter for a short while until land rises to again form a lake. CO2 280 ppm. Temperatures slightly higher than today.

8000 years ago: The Ancylus lake. The outflow is first through Svea Alv, then as land rose the outflow switched to Oresund. Temperatures were higher than today. CO2 level 280 ppm. River flows at the emptying of the Ice lakes causes formation of  “giant kettles”,  an example of which is shown in the figure below:

The largest of Brobacka’s “jättegrytor”, with a diameter of 58 feet. This particular giant kettle might have been mostly formed by a stream under the ice cap while the ice was melting.

6000 years ago: Most of the inland ice has now melted, and the Oceans have risen to today’s level, so the Belts and Oresund open up and the Litorina Sea is formed. temperatures are higher than today, CO2 level was 280 ppm.

3500 years ago: The Minoan warming period. Temperatures much warmer than today. Elm, Hazel, Oak and Linden grew way up in the Bothnian bay, today the northern limit is about 250 miles further South. The CO2 level was 280 ppm.

2000 years ago: The Roman warming period. Great times up North. Wine grapes grew in the British Midlands, the Scandinavian population grew rapidly. CO2 level was still 280 ppm.

1500 years ago: Climate is turning colder, migrations out of the Nordic and Germanic countries. Harvest failures. CO2 level was constant at 280 ppm.

1200 years ago: Rapid depopulation, Bubonic Plague, failed harvests, mass starvation, climate turning much colder. CO2 level 280 ppm.

1000 years ago: Medieval warming period. Climate about one degree warmer than today. Leif Ericson sails to America. Cheese farms established on Greenland. CO2 level 280 ppm.

500 years ago: Little Ice age. Climate much colder than today. The Swedish army, including artillery crosses the Belts on ice in 1658. CO2 level 280 ppm.

Why am I going through all this? All these climate changes occurred with the CO2 level being constant at 280 ppm. The land in Northern Sweden is still recovering from the Ice age, and land is still rising out of the ocean at the rate of up to three feet per century. The temperature is still recovering from the little ice age, but is not yet back to the Medieval Warming period, much less the Roman warming period, not to mention the Minoan temperature optimum. The CO2 level has risen to 405 ppm, but CO2 is only a minor player in affecting Climate change.

As I have mentioned in a previous blog: https://lenbilen.com/2017/04/10/thanks-to-clouds-the-temperature-governor-is-alive-and-well-on-planet-earth/ clouds are the temperature regulators, and it will do us well to concentrate on the real threats to our earth on Earth Day, such as clean air (CO2 is clean air) and clean water.

When you celebrate Earth Day 2019 look up to the sky. If there are any clouds, especially cumulus clouds, look how they form, change and dissipate, and marvel that they are the regulators of the climate so we never have to worry about a thermal runaway, no matter what level of CO2. We will have another ice age though, but more CO2 will delay its onset.

When the real cool-down occurs, we will have to produce a lot more energy than now, otherwise we will all be doomed. Increased CO2 levels only slows town the onset of the next ice age. In addition there is not enough free carbon left in the world to carry us through. Only Thorium based nuclear energy ( https://lenbilen.com/2017/07/14/twenty-two-reasons-to-rapidly-develop-thorium-based-nuclear-power-generation/ )

or maybe fusion energy will have a chance of carrying us through.
