No, Greenland is not approaching a melting ‘tipping point’

By James Taylor |January 1st, 2020| General Information| 322 Comments

An article on the climate activist website Inside Climate News (https://insideclimatenews.org/news/23122019/greenland-ice-sheet-climate-tipping-point-temperature-duration-sea-level-rise-pnas-study) claims Greenland is perilously close to a tipping point that will destabilize the Greenland ice sheet and result in substantial ice melt and sea level rise. The ice sheet’s stability through much warmer temperatures that lasted several thousand years during early human civilization, however, strongly contradicts the assertion.

Even climate alarmists have long acknowledged that temperatures would need to continue rising for many centuries before threatening a substantial melting of the Greenland ice sheet. A new study, however, claims that analysis of fossilized sea shells off of the coast of Greenland shows sustained warm temperatures several hundred thousand years ago indicate Greenland could eventually reach a tipping point of substantial sustained ice loss. Inside Climate News reports the authors of the study claim the sea shells indicate a similar tipping point may be just a few decades away.

“Our best estimate suggests that modest warming was able to dramatically reduce the parts of the Greenland Ice Sheet that are hard to melt away,” said one of the authors of the study, according to Inside Climate News.

Large sections of the ice sheet could melt “due to only a small increase in temperatures relative to today,” said the author.

However, peer-reviewed scientific research and even the United Nations Intergovernmental Panel on Climate Change (IPCC) have long established that temperatures remained much warmer than today for 4,000 years, during a period between 4,000 and 8,000 years ago. Yet the Greenland ice sheet did not experience any such tipping point.

Data published by the UN IPCC show quite clearly that temperatures can be much warmer than today and remain that way for thousands of years without reaching a tipping point for the Greenland ice sheet. But that won’t stop alarmists from continuing to assert their Climate Delusion that defies scientific facts.

Hi Brumar,

Living in Wisconsin, in the middle of America's Dairyland, I can vouch for very poor yields in both corn and soybeans this year.

The delayed planting and harvest was solely due to excess moisture and water standing in the fields. As I type there still are stands of corn not yet harvested and in particular more soybeans.

The early November snow that blanketed our unharvested crop lands ended up once again being standing water in the fields.

There were three categories of crops that were delayed to three different levels.

1) corn the is chopped and stored in plastic bags on the ground. This "chopping" of the entire corn stalk was late to harvest, but first to come off the fields as is normal. The typical big choppers that cut and chop the corn stalks are tall with big tires and lots of horsepower. As they chop and blow the corn, semis with large trailers drive along side the chopper and carry the load of the chopped corn. This fall I saw not one but two medium sized 4x4 tractors chained to these semis dragging them through the mud and making ruts 6-9 inches deep from the trailers skinnier tires.

2) Corn combines shucking the cobs and separating the seed and holding them in large hoppers for off loading into trucks waiting on the sides of the road. Since these large tored and high horsepower combines cut the corn stalk 6-10 inches above the ground, harvesting was able to take place even when they created 6-8 inch deep ruts.

3) soybeans are harvested by the same combines, but with a different cutting head. Soybeans are cut to with in 2-3 inches from the ground and the vines are bailed and used for cow bedding. That is why there are still soybeans in the field. The combines are still creating ruts in the ground and if attempted to harvest the muddy fields - they'd literally be scooping dirt. Additionally soy beans must be harvest and dried so that mole does not happen when being stored. Now that the ground has frost in the upper layer of the ground 75% of the soybean crop has been harvested. It is once again warm in Wisconsin and the ground has lost the frost. There still are 15 - 25 oercent of the soy bean crops still on the field in areas of Wisconsin that border lake Michigan (which keeps the humidity higher and temps lower.

From my novice observations, our crop delays were more the fault of excess clouds and moisture in the spring and fall. From my perspective the crops were lower yields from past years (the farmer who grows crops on my land confirms this).

These delays and lower yields were the result of the Grand Solar Minimum effects and not the result of CO2 increases (which I believe helped make the most out of a shortened growing season).

I still maintain the climate change alarmists are those who want to control our income (tax us) and have power and control over our rights and lifestyles.

It's far more about the money and power, than about changing our environment!

End of the Wisconsin crop report - which is really just a story about muddy fields - and yes it has been seen before.
