Why Climate Change Won't Matter in 20 Years

XXXIII have you actually read this thread your question was addressed about 150 pages back if not more.

Loss of sea ice is caused by IMO the 40 plus Russian ice breakers. They are already at work breaking ice near Greenland you can see the difference if you look at the time lapse cryosphere photos of the last two weeks

Ice breakers do not not melt ice. They just move it around.

and it all goes to hell?

Trace substances are like that. Without that trace amount of CO2 the earth would be a ball of ice. O3 is only 3-10 ppm; however, it protacts you from UVB.

Using carbon isotope analysis the 40% increase in atmospheric CO2 from the mid-18th century is directly traced to the burning of fossil fuels.

The last time atmospheric CO2 was at 400 parts per million was during the ancient Pliocene Era, three to five million years ago, and humans didn’t exist.

- Global average temperatures were 3 to 4 degrees C warmer than today (5.4 to 7.2 degrees F).
- Polar temperatures were as much as 10 degrees C warmer than today (18 degrees F).
- The Arctic was ice free.
- Sea level was between five and 40 meters higher (16 to 130 feet) than today.
- Coral reefs suffered mass die-offs.

“The extreme speed at which carbon dioxide concentrations are increasing is unprecedented. An increase of 10 parts per million might have needed 1,000 years or more to come to pass during ancient climate change events. Now the planet is poised to reach the 1,000 ppm level in only 100 years if emissions trajectories remain at their present level.”

Jack I never said that ice breakers melt it I know that they just break it into smaller pieces so it can float to warmer waters and melt faster than if it were still part of the main icepack. Look at the last couple weeks of photos from cryosphere . Look mainly along the Russian coastline. Seems to be breaking up rather rapidly to me for the time of year . The Russians did say that they would do anything it takes to open the Arctic sealanes to freighters year round within the next ten years. I posted a link to that article about 150 or so yes back. ( BTW I did say it was my opinion ) only time will tell.

Your opinion requires some sort of evidence.

Below average sea ice extent is in part a result of higher than average temperatures that have plagued the Arctic all winter. Air temperatures at the 925 hPa level from December 2015 through February 2016 were above average everywhere in the Arctic, with hotspots near the Pole and from the Kara Sea towards Svalbard exceeding 6 Celsius degrees (11 degrees Fahrenheit) above average. These higher than average temperatures continued into March, with air temperatures during the first two weeks reaching 6 degrees Celsius (11 degrees Fahrenheit) above average in a region stretching across the North Pole toward northern Greenland, and up to 12 degrees Celsius (22 degrees Fahrenheit) above average north of Svalbard.

These unusually warm conditions have no doubt played a role in the record low ice extent this winter. Another contributing factor has been a predominance of southerly winds in the Kara and Barents seas that have helped to keep the ice edge northward of its typical position. This area has also seen an influx of warm Atlantic waters from the Norwegian Sea.

Wind,not ice breakers, is moving the ice around. Warm temperatures is melting it.

Jack you just said it the Arctic was ice free but you told me that it wasn't ice free a couple dozen pages back when I posted that about the lack of Arctic sea ice causing Arctic like conditions in the middle northern attitudes. During the height of the last ice age. Circa 25 k years ago.

The paper I linked to about the Russian icebreakers. And the time lapse photos from cryosphere are already available . The rest will become apparent in the next few years.

Check my amended post.

Wind is moving ice around, record warm temperatures is melting the ice.

When did I say the Arctic was ice free?

EDIT - 3-5 million years ago.

Great post. It really sums up what the real problem is and will be.

Jack yes I read all that but read between the lines. The ice breakers break the pack into smaller pieces so the wind can move it easier. . Its all about the money jack an ice free Arctic would increase pprofits for major shipping companies between china and Europe and the entire Atlantic seaboard. However they dont want to admit it is being done . Follow the money jack. It is there. We both know to what lengths people will go to make money at the expense of the planet.

Your math errors don't help your argument. Further more, your knowledge of physiology is weak:

If the CO2 were 3% we would all be feeling poorly and might be dead from long term effects. The OSHA 12 hour limit is 0.5%.

There is about 0.039% CO2 in the air. 100 ppm (0.01%--another error) takes that to 0.049%, or a 25% increase. Yeah, it's a big deal.
