Finally, an Unbiased and Objective Climate Science Report

by T. Gallaudet, Aug 26, 2025 in TheEpochTimes

The recent report released by Energy Secretary Chris Wright on the climate impacts of greenhouse gas (GHG) emissions in the U.S. has caused quite a stir in the climate science arena. “Outrage,” “pushback,” and “criticized” are the words used in many of the headlines about it.
To better gauge the overall opinion of the report, two journalists from the Associated Press asked members of the climate science committee if they believed that it accurately portrayed the current “mainstream view of climate science.”

The Medieval Warm Period: A Global Phenomenon?

by M. Wielicki, Mar 06, 2025 in IrrationalFear

The debate over the characteristics and impact of the Medieval Warm Period (MWP), roughly dated from 950 to 1250 AD, lies at the heart of discussions on historical climate variability and its implications for understanding current climate change.

Following the publication of the Intergovernmental Panel on Climate Change (IPCC)Third Assessment Report in 2001, the MWP was essentially erased from the paleoclimatological record in favor of the ‘hockey stick’ graph. This disappearance remains a point of contention that has been particularly prominent in public and scientific debate.

The ‘hockey stick’ graph, first published by Michael Mann, Raymond Bradley, and Malcolm Hughes in 1999, depicted temperature anomalies over the past millennium. It showed relatively minor temperature fluctuations for most of the last millennium (the “shaft” of the hockey stick) and a sharp rise in temperatures in the 20th century (the “blade” of the hockey stick). This presentation suggested that the modern warming period has been unprecedented over the last millennium. This finding has been at the core of calls for robust measures aimed at addressing climate change.

A warming pulse in the Antarctic continent changed the landscape during the Middle Ages

by E. Forte et al., Apr 11, 2025 in Nature (OPEN ACCESS)

Abstract

The Antarctic landscape is one of the most stable environments on the Earth, at least since approximately 14 million years ago when most glaciers in continental Antarctica changed from temperate to cold-based, and previous extensive fluvial activity disappeared. Here, we detected a large landscape change on a coastal glacier in continental Antarctica (Boulder Clay Glacier) that occurred in the Medieval Warm Period. Such change consists in a glacial unconformity marked by a continuous sediment layer and an erosion channel on the past glacier surface. This channel, more than 4 kilometers long, represents a local deepening of a glacial unconformity that cuts the underlying glacial strata and was clearly imaged and mapped by Ground Penetrating Radar data. Four boreholes were allowed to calibrate the sediment layer so identified because it was observed in all boreholes at depths between 1.85 and 3.07 m. Moreover, the occurrence at a depth of 11.11 meters of mosses suitable for the dating through radiocarbon dating provided the age of 1050 calibrated years before the present, implying that the erosion event occurred during the Medieval Warm Period between 900 and 989 before the present.
