Climate alarmists have long contended that the Medieval Warm Period (MWP) was not a worldwide phenomenon, primarily because that reality would challenge another of their major claims, i.e., that late 20th-century temperatures were the warmest of the past millennium or more. Thus, it is important to know what has been learned about this subject in different parts of… Read More »
Climate alarmists have claimed for quite some time that late-20th-century and early-21st-century global temperatures were so high as to merit the word “unprecedented” when comparing them to temperatures of the past millennium or two; and they also claim that this achievement was both driven and sustained by the carbon dioxide or CO2 released to the air by mankind’s… Read More »
Knowledge of the past is extremely important when it comes to contemplating future climatic possibilities; for what’s happened before can clearly happen again. Hence, this summary briefly reviews the history of Canadian droughts with respect to how they varied over the past several centuries in response to significant changes in global air temperature but very little change in… Read More »
In the 19th century, British Prime Ministers used to say there were “lies, damned lies, and statistics”. In the 21st century, we may say there are frauds, serious frauds, and IPCC Assessment Reports. Recall, for instance, the notorious graph in the Fourth Assessment Report that falsely indicated that the rate of global warming is accelerating and we are… Read More »
The celebrated mathematician, astronomer and philosopher of science Abu Ali Ibn al-Haytham, or Alhazen, is justly celebrated as the founder of the scientific method. His image appears on Iraqi banknotes and on the postage stamps of half a dozen nations of the ummah wahida. Al-Haytham, unlike Naomi Oreskes, did not consider that consensus had any role in science.
Was there a Medieval Warm Period anywhere in addition to the area surrounding the North Atlantic Ocean, where its occurrence is uncontested? This question is of utmost importance to the ongoing global warming debate, since if there was, and if the locations where it occurred were as warm then as they are currently, there is no need to… Read More »
We begin our investigation into this subject with the words of Matthews et al. (2005)1, who wrote that “coupled climate-carbon cycle model simulations have identified an important positive feedback between the terrestrial carbon cycle and climate, whereby future carbon uptake declines under anthropogenic climate warming.” Such is the conclusion of those who see a bleak future in store… Read More »
This review begins with the study of Dahl-Jensen et al. (1998)1, who used temperature measurements from two Greenland Ice Sheet boreholes to reconstruct the temperature history of this portion of the earth over the past 50,000 years. Their data indicated that after the termination of the glacial period, temperatures steadily rose to a maximum of 2.5°C warmer than… Read More »
