Climate Change Mega Thread

[Jlabute]

Don't like WUWT? It is a blog like skepticalscience, but better. WUWT at least sports a reward for being one of the top science sites. Blogs are important since you can't carry a conversation directly in a science study and just because something is 'peer-reviewed' that doesn't make it better science. Many science articles get pulled after peer-review accepts them. Peer-review means very little.

As for Greenland, there are things we know and don't know. Greenland has a massive mantle plomb below the ice, melting it from beneath.
https://www.eurekalert.org/news-releases/544979

The media lies and tries to continually stir up fear to what is happening in Greenland.
https://www.realclearenergy.org/article ... 93927.html

Since the last ice age, Greenland has been losing and gaining ice mass. On average, Greenland has been losing ice for 14,000 years and recently this trend has slowed. In fact some receded glaciers uncovered roads and tools used by Vikings. So, growing ice pushed Vikings out of Greenland at one point. Over-all the trend is to lose ice, but not because of man. From 2002 to 2012, Greenland lost ~0.1% of its mass, and this relies heavily on how accurately we can measure gain and loss. Sea level rise is not accelerating and ice melt is not accelerating. Sea level on average has been rising since the last ice age and is rising slower today than thousands of years back. In fact, sea level was 10 to 15 feet higher 5 thousand years ago and 4 to 6c warmer during a time when CO2 was at an all time low. Earth has a chaotic and dynamic climate that goes well beyond the understanding of anyone or any AI model. A blanket statement that Greenland is melting because of man is beyond stupidity.

The Arctic ice extent is now back within two standard deviations of the 1991-2020 mean, which hasn’t happened since 2014. Arctic ice is currently the second highest it has been in the last 15 years, and 20 vessels are stuck in arctic ice.

From Rex Murphy, National Post


“ If our Earth really is in danger, shouldn’t the House of Commons stay in full, all-member, attendance day and night till it isn’t? Or was that five-word scream just a slogan of the moment, one not meant to live up to the emergency it declared? Was it, far more likely, just a vast and hollow distraction from — shall we say — more local, more “in-Canada” problems, problems for which the Liberal government has real responsibility to deal with and fix.


Problems like the need for clean water for First Nations, for example. Or the beginning of a rampaging crisis of inflation brought on in large part by reckless overspending of historic scale during the pandemic. Was it a cover for more of their global warming obsession and their ludicrous carbon taxes — due to rise incidentally — which are helping to fuel that inflation? Or a cover for not attending to the real grievances of the Western provinces, or P.E.I.’s recent hit on its main export? Then there’s the rise in lumber duties. And a pending world-energy crunch. Rather than disaster predictions every second day, how about real disaster preparation?”

[Jlabute]

Justin Trudeau and every party left is more than willing to destroy Canada economically over a mere 1% of an assumed global problem. Even if Canada’s population was zero, one would not be able to detect the outcome in global CO2 or climate. Canada cant own every other countries portion either. There is no rush to fix one percent of an assumed problem but as old buildings and vehicles are replaced, and new energy generation like SMR come online and we supercharge our electric economy with plentiful cheap power, our slice of the pie will diminish naturally.

Is earth really in danger? What are the signs? Coral is raging back. Arctic ice is raging back. Antarctic ice still creeps higher. Polar bear populations are growing. Greenland ice melt slowed significantly.

The Planet Has Lost Half of Its Coral Reefs Since 1950

Scientists have long known that reefs are in peril, but a new study published today in the journal One Earth quantifies coral losses around the world. The in-depth analysis reveals half of coral reefs have been lost since the 1950s. Scientists say climate change, overfishing and pollution are decimating these fragile ecosystems and putting communities and livelihoods in jeopardy. Their study, which is among the most comprehensive assessment of reefs and their associated biodiversity to date, underscores the rapid pace of global coral collapse.

The Arctic.....

The monthly average extent for October 2021 was 6.77 million square kilometers (2.61 million square miles). This ranked eighth lowest in the long-term satellite data record, tied with 2017. It was 1.44 million square kilometers (556,000 square miles) greater than the record low of 5.33 million square kilometers (2.06 million square miles) recorded in 2020, and 1.58 million square kilometers (610,000 square miles) below the 1981 to 2010 long-term average. Ice growth was robust across the Eurasian side of the Arctic, including the East Greenland Sea, but there was little expansion of ice southwards within the eastern Beaufort Sea.

Antarctic.....

A newly completed 40-y record of satellite observations is used to quantify changes in Antarctic sea ice coverage since the late 1970s. Sea ice spreads over vast areas and has major impacts on the rest of the climate system, reflecting solar radiation and restricting ocean/atmosphere exchanges. The satellite record reveals that a gradual, decades-long overall increase in Antarctic sea ice extents reversed in 2014, with subsequent rates of decrease in 2014–2017 far exceeding the more widely publicized decay rates experienced in the Arctic. The rapid decreases reduced the Antarctic sea ice extents to their lowest values in the 40-y record, both on a yearly average basis (record low in 2017) and on a monthly basis (record low in February 2017).

Coral reef is at an all-time high in 2021, since 1985. What disturbs me the most about your link is that this is a well-known picture of healthy coral being called bleached, when it isn't. A number of authors have parroted this lie. There are lots of articles on it, here is one.

No one knows the future. You can stack this upon 1000 other failed predictions and then send $20 to WWF to save the polar bears. They've been looking for suckers with money since that is their business model and I am sure everyone knows their 'prediction' without stating it. Funny they never predicted a growing population. It is lame to hold any credence in bad models, based on bad assumptions, which can't determine what the arctic will look like in 2050, let alone bear population. Their population might increase by 20% too. You should be attune to the use of language like 'might', 'maybe', 'ya never know', 'sometimes maybe', 'sometimes might kind of' especially in the absence of science or reason.

October 2021 compared to previous years

The downward linear trend in October sea ice extent over the satellite record is 82,100 square kilometers (31,700 square miles) per year, or 9.8 percent per decade relative to the 1981 to 2010 average (Figure 3). While percentagewise, the overall long-term trend is largest in September, the actual amount (based on the linear trend) of ice lost per year is larger in October: 82,100 square kilometers (31,700 square miles) versus 81,200 square kilometers (31,400 square miles) in September.

Overall, since 1979, October has lost 3.45 million square kilometers (1.33 million square miles) of ice, based on the linear trend. This is equivalent to twice the size of the state of Alaska.

Oh you mean the little blip in Sept. 2021? Here's the latest news.....

Since the Antarctic maximum sea ice extent was reached on September 1, 2021, ice extent has been in a steep decline. Extent went from being above the interdecile (ninetieth percentile) range to being below the tenth percentile for most of October. As a result, sea ice extent in the Antarctic is currently tracking as the third lowest, behind only 2016 and 1986. Sea ice extent is particularly low along the western side of the Antarctic Peninsula, including the northern Weddell Sea and the central Indian Ocean sector. Air temperatures at the 925 hPa level (about 2,500 feet above the surface) were up to 6 degrees Celsius (11 degrees Fahrenheit) above average within the Weddell Sea. A strong low pressure feature in the Amundsen Sea and above average air pressure in the area south of Australia drove winds that led to the pattern of sea ice extent around the continent.

New Study - Coral bleaching NOT caused by human emissions, but by Cloud Radiative Forcing.

Great Barrier Reef (GBR) warming and coral bleaching have often been assumed to be driven by human greenhouse gas emissions and/or El Niño events. A new study finds a better robust correlation between natural cloud cover modulation of solar radiation, shallow-water warming, and bleaching.



Peer reviewed paper here.

Another NEW paper also studied coral bleaching during the little ice age. Very Interesting.

Is that right? Interesting........

Recent climate models project that a doubling of atmospheric CO2 above pre-industrial levels could cause temperatures to soar far above previous estimates. A warming earth, researchers now say, will lead to a loss of clouds, allowing more solar energy to strike the planet........

The studies have changed how the models treat clouds, following new field research. They suggest that the ability of clouds to keep us cool could be drastically reduced as the world warms — pushing global heating into overdrive........

Recent concern about how accurately the models handle clouds has focused on the blankets of low clouds that any international flyer will have seen extending for hundreds of miles below them across the oceans. Marine stratus and stratocumulus clouds predominantly cool the Earth. They shade roughly a fifth of the oceans, reflecting 30 to 60 percent of the solar radiation that hits them back into space. In this way, they are reckoned to cut the amount of energy reaching the Earth’s surface by between 4 and 7 percent.

But it seems increasingly likely that they could become thinner or burn off entirely in a warmer world, leaving more clear skies through which the sun may add a degree Celsius or more to global warming. As Mark Zelinka of the Lawrence Livermore National Laboratory, lead author of a review of the new models published last month, has put it: The models “are shedding their protective sunscreen in dramatic fashion....

https://e360.yale.edu/features/why-clou ... on-warming

It's interesting to note what's causing the reduced cloud cover and therefore more radiative forcing causing coral bleaching according to the new models........increase in CO2 ...........and in turn cherry picked usual wrong conclusion from the pseudoscience blog, whatsupwiththat.

[Jlabute]

Cloud cover makes the most sense plus the study has a much better correlation than any other theory.

Over the last decade, we have had a massive grow back of coral and this probably gave the team an opportunity to relate it to cloud cover. Seeing coral are shallow water organisms, it would make sense that shallow water temperature varies much more through cloud cover cycles. Cloud cover changes more based on ocean cycles and various factors.

CO2 does not control the distribution of clouds!
