Earth's CO2 Levels

Concentrations of carbon dioxide in the atmosphere in May were 50 percent higher than during the pre-industrial era, reaching levels not seen on Earth for about four million years, the main US climate agency said on Friday.

The amount of carbon dioxide in the atmosphere passed the threshold of 420 parts per million (ppm), the National Oceanic and Atmospheric Administration (NOAA) said. PPM is a unit of measurement used to quantify pollution in the atmosphere.

Last May, the rate was 419ppm, and in 2020, 417ppm.

Global warming caused by humans, particularly through the production of electricity using fossil fuels, transport, the production of cement, or even deforestation, is responsible for the new high, the NOAA said.

CO2 is a greenhouse gas that traps heat, gradually causing global warming. It remains in the atmosphere and oceans for thousands of years.

Its warming effect is already causing dramatic consequences, noted NOAA, including the multiplication of heatwaves, droughts, fires or floods.

“Carbon dioxide is at levels our species has never experienced before – this is not new,” said Pieter Tans, a scientist with the Global Monitoring Laboratory at NOAA.

“We have known about this for half a century, and have failed to do anything meaningful about it. What’s it going to take for us to wake up?”  READ MORE...

Something to Ponder

Follow the math...It takes between 21 to 35 days for a Russian oil tanker to get to US ports to be offloaded.


It takes between 35 and 60 days for a tanker from the Middle East to make the same trek.


It takes about 10 hours to load the tanker and up to 24 hours to unload. If it has to wait in port to get to an unloading dock, it can take up to 3 days.


The average tanker burns 2,625 gallons of diesel fuel per hour. 22.38 pounds of CO2 are created from burning 1 gallon of diesel fuel.


So, in one hour, a tanker ship hauling oil to a refinery in the US creates 58,757.5 pounds of CO2 per hour. Averaging the travel time of the tankers, that's 27.67 million tons of CO2 PER TRIP.


In comparison, your car creates between 6 and 9 tons PER YEAR.

Without going into all the equations of how many tankers come to the US per year, let alone our exports, will someone please explain; how can banning and limiting the drilling our own oil and moving it through pipelines, along with importing oil from Canada via pipeline NOT BE MORE environmentally "green" for the world!?!
