THE WORLD’S population may never grow as large as many had previously assumed. In a new paper, researchers at the Institute of Health Metrics and Evaluation at the University of Washington project that the global population will top out in 2064 and then fall steadily. Current estimates by the UN’s Population Division reckon it will continue to grow until at least 2100. As a result, the IHME estimates a total population of 8.9bn in 2100; the UN places the number at about 10.9bn.

Also the Danish Meteorological Institute (DMI) projects a sturdy Arctic sea ice extent for this July, meaning no falling summer ice extent trend since 2007! The climate alarms are being muffled.
Snowfan here gives us the latest on global mean temperature and Arctic sea ice.
After the year’s low in June 2020, with an anomaly of +0.48°C from the 1981-2010 WMO climate mean, the global 2-meter temperatures (black line) depicted below shows the July 16, 2020 analysis and forecast up to July 23.
A surprising DMI forecast was issued on July 14, 2020 which projects strong growth of Arctic sea ice areas for July 2020. If this expert forecast is correct, it would mean there’s been a strongly positive summer trend since 2007 – instead of the ridiculous Al Gore complete meltdown.

The National Oceanic and Atmospheric Administration, which relies on perpetuation of the Climate Delusion to maintain high funding, is falsely claiming there has been “extraordinary” sea level rise since 2000. Fox News and other media outlets are devoting substantial attention to the assertion by NOAA bureaucrats. However, there is simply nothing extraordinary about recent sea level rise.
According to Fox News, NOAA claims “Communities in coastal areas of the U.S. saw record-setting high-tide flooding last year, part of a trend of rising seas … [and an] ‘extraordinary’ rise in high-tide flooding since 2000.”
“Damaging floods that decades ago happened only during a storm now happen more regularly, even without severe weather,” Nicole LeBoeuf, acting assistant administrator for NOAA’s National Ocean Service, told reporters in a conference call.
Even if high-tide flooding has increased in recent years, natural factors are the primary cause.
As detailed in Climate at a Glance: Sea Level Rise: Data shows global sea level has been rising at a relatively steady pace of approximately one foot per century since at least the mid-1800s, which was long before coal power plants and SUVs. Moreover, the United Nations Intergovernmental Panel on Climate Change (IPCC) confirms here has been no significant recent acceleration.
Global sea level has risen approximately 400 feet since the beginning of the end of the most recent ice age—approximately 20,000 years ago. The rate of sea level rise has risen and fallen at various times since then, slowing and increasing on the order of tens, hundreds, and thousands of years over the past 20,000 years. All of that variance had nothing to do with human activities. Indeed, as NASA reports, sea level always rises between ice ages as ice sheets retreat. During the last interglacial period between ice ages, seas were four to six meters higher than we are experiencing today….

As previously explained before, increased melting/ice loss of Antarctica’s Pine Island and Thwaites glaciers is the result of geologically induced heat flow emitted from underlying bedrock “hotspots,” not climate change (Figure 1).
All but a very minor amount of Antarctica’s glacial ice melting occurs in the western portion of this continent. The most rapid and greatest ice mass loss areas are in West Antarctica.
They are positioned directly above geographically extensive and high heat flow geological features. This association is thought to be strong evidence of a cause and effect relationship.
Discussion of evidence supporting the contention that the melting of Pine Island and Thwaites glaciers is the result of bedrock heat flow begins with a review of the regional geology (refer to Figure 1).
The Pluton Rich “hotspot” is a 61,000-thousand-square-mile area that is home to numerous high-heat-flow lava pockets that are bounded and fueled by deep earth reaching faults.
Several detailed research studies document the existence and configuration of this area. This lies along the West Antarctic Rift.
The Mount Erebus Volcanic Complex “Hotspot” is the most geologically active portion of Antarctica. It is a 25,000-square-mile high-heat-flow area, much of which is absent of glacial ice.
The absence of glacial ice across a huge portion of West Antarctica is extremely unusual and exceedingly difficult to explain by invoking global warming.
