Climate Change Reconsidered

Comparing Earth’s Sea-Level and Energy Budgets (3 Jan 2012)

In spite of all one hears, sees and reads in the popular press about unprecedented global warming and recent accelerated melting of glaciers and ice sheets, as well as short-term accelerations in sea level rise detected by means of satellite technology, the mean rate-of-rise of Earth’s global ocean appears to have remained remarkably constant ever since 1972 ...

Empirical Harmonic Models Project “Sunnier” Climate Scenarios Ahead (3 Jan 2012)

Recent work by Scafetta (2011) demonstrates that using an empirical harmonic climate model can reproduce the global climate record of the last 150 years more faithfully than general circulation models (GCMs). The GCMs were those employed by the Intergovernmental Panel on Climate Change. The author also shows that because these GCMs cannot reproduce decadal and interdecadal climate variability, the models likely over-project the magnitude of the warming that may occur over the next century. Lastly, this work provides strong evidence that natural variability is at least partly due to external forcing that derives from the relationship between the sun and its larger planets as well as the Earth’s moon ...

ENSO Variability Over the Past Millennium (3 Jan 2012)

What does it imply about the likely relative strength/frequency of El Niño and La Niña events in a future warmer world? And what does that imply about the reliability of today’s climate models? ... Read More

Primary Production in Future CO2-Enriched Ocean Water (3 Jan 2012)

Observations once again suggest that the planet’s rising atmospheric CO2 concentration may well stimulate oceanic primary production and thereby enable the sustaining of a greater population of higher-trophic-level marine organisms ... Read More

Tropical Damselfish Successfully Adapt to Higher Temperatures (4 Jan 2012)

Experimental evidence shows tropical fish can adapt to rising water temperatures much faster than previously thought ... Read More

The Future of the Brazilian Amazon (4 Jan 2012)

One environmental impact that has raised serious concerns is the loss of Amazonian forest through indirect land use change (ILUC), whereby “agricultural activities displaced from one region are reconstituted in another one” ... Read More

Nearly Half a Millennium of Antarctic Temperatures (4 Jan 2012)

Climate alarmists have long predicted that CO2-induced global warming -- which they claim has (1) accelerated significantly over the course of the 20th century and is (2) unprecedented with respect to the past millennium or more -- should be (3) greatly amplified in Earth’s polar regions. However, results of a recent paper clearly indicate that all three of these climate-alarmist claims are false in regard to this portion of the planet’s southern polar region ... Read More

Exciting El Niño News: More Evidence of a Solar Trigger (4 Jan 2012)

Within the literature, there is disagreement about what triggers El Niño. Some believe that El Niño is the result of internal variability, while others have shown a solar link. A paper by White and Liu (2008) demonstrated that the El Niño may result from the phasing of two sub-harmonics in the 11-year solar cycle. They also show that general circulation models which include the 11-year solar cycle can replicate the behavior of El Niño quite well. This bodes well for long-range forecasting on the time scale of three to 10 years ... Read More

Farm and Range Management to Mitigate and Adapt to Climate Change (4 Jan 2012)

Although based on the claim that rising atmospheric CO2 concentrations are a threat to both nature and humanity, the policy prescriptions of a recent editorial in the Journal of Soil and Water Conservation should resonate with climate alarmists and skeptics alike ... Read More
