Warming Prompts Range Expansion of West Australian Reef Fish (23 June 2015)
Periodic warming of seawater in different parts of the world can enable the poleward expansion of the ranges of many fish species, such as the endemic reef fish Choerodon rubescens that is found along the western coast of Australia...

Assessing the Global Extent of Drought-Induced Forest Dieback (23 June 2015)
In light of the global warming that ceased nearly two decades ago, droughts have been predicted -- and are still periodically projected -- to become more severe and widespread in future decades, leading to the dieback of many of the world's forests. A new study, however, suggests these projections have little solid support in terms of real-world data...

A Submerged Aquatic Plant in a CO2-Enriched and Warmer World (17 June 2015)
The "twin evils" of the climate alarmist crowd (global warming and water acidification) do no harm to a perennial macrophyte that is widely distributed throughout the waters of China's middle and lower Yangtze River basin. In fact, they help the important plant to grow even better than it does currently...

Lamenting the Double ITCZ Bias in CMIP5 Climate Models (16 June 2015)
It is becoming ever more difficult to put much faith in the ever-evolving -- but never quite getting to where they need to go -- climate models, which are now at the CMIP5 state of development and testing, but are still found to be suffering from numerous different biases...

The Tenth International Conference on Climate Change (ICCC-10) (13 June 2015)
The Tenth International Conference on Climate Change (ICCC-10) was held this past Thursday and Friday at the Washington Court Hotel in Washington, DC. Dr. Craig D. Idso delivered a talk discussing serious flaws in the U.S. Government's official economic analysis of climate change. That presentation can be viewed here, where Dr. Idso's remarks begin at the 15 minute and 30 seconds mark. The text of his talk can be downloaded here, and the accompanying slides can be downloaded here. Presentations of other speakers can be accessed from the conference website, located here.

Redband Trout Feeling the Heat of a Desert ... But Adapting to It! (8 June 2015)
In a classic case of evolutionary adaptation to extreme thermal stress, redband trout from a desert climate have a much larger number of strongly differentially expressed genes in response to heat stress, which suggests that "a combination of genes has evolved for redband trout to adapt in their desert environment." And if redband trout can do it, many other species should also be able to take the heat of potential global warming and bask in its future progression...

Two Centuries of Drought on the Eastern Mongolian Plateau (2 June 2015)
What do they tell us about the uniqueness - or not - of the region's droughts of the past two decades? Once again, we find yet another reliable reconstruction revealing there is nothing unusual, unnatural, or unprecedented about current (or past!) precipitation variability -- for either floods or droughts -- that would suggest a CO2-induced influence...
