Daily carbon dioxide crosses 430 ppm

The above image illustrates the threat of a huge temperature rise. The red trendline warns that the temperature could increase at a terrifying speed soon.

The global surface air temperature was 13.87°C on March 8, 2025, the highest temperature on record for this day. This is the more remarkable since this record high temperature was reached during a La Niña.

The shading in the image highlights the difference between El Niño conditions (pink shading) and La Niña conditions (blue shading). An El Niño pushes up temperatures, whereas La Niña suppresses temperatures. We’re currently in a La Niña, so temperatures are suppressed, but this is predicted to end soon. NOAA predicts a transition away from La Niña to occur next month.

The transition from La Niña to El Niño is only one out of ten mechanisms that could jointly cause the temperature rise to accelerate dramatically in a matter of months, as described in a previous post. Another one of these mechanisms is the increase in greenhouse gas concentrations.

Antarctica Ice Growing Across Large Areas for at Least 85 Years, Aerial Photos Show

by C. Morrison, Mar 12, 2025 in WUWT


Sensational new discoveries arising from long-forgotten early aerial photographs indicate that ice has remained stable and even grown slightly since the 1930s over a 2,000 km stretch of East Antarctica. In a recent paper published in Nature Communications, researchers from the University of Copenhagen came to their conclusions by tracking glacial movement in an area with as much ice as the Greenland ice sheet. The findings are unlikely to feature in narrative-driven mainstream media. The silence will probably replicate the response to another recent paper that found the ice shelves surrounding Antarctica grew in overall size from 2009-2019.

The Copenhagen scientists examined hundreds of old aerial photographs taken for mapping work in 1937. The images were supplemented with a number of photographs taken in the 1950s and 1974 of the same area and a 3D computer reconstruction was produced. This allowed the researchers to examine the evolution of glaciers over a significant time period. In order to determine if recent trends exceed the scale of natural variability, long-term observations are said to be vital.

“Compared to modern data, the ice flow speeds are unchanged. While some glaciers have thinned over shorter intermediate periods of 10-20 years, they have remained stable or grown slightly in the long term, indicating a system in balance,” it was noted.

Actual long-term scientific observations will always beat media-friendly computer-modelled pseudoscientific opinions and alarm drummed up by short-term outliers. The authors note that using data from historical sources such as early photographs provides extensive coverage across large areas with detailed temporal and three-dimensional information. Geological evidence covers longer time scales with temporal uncertainties of thousands of years, while estimates from ice cores are generally very local and spatially confined. In Antarctica, it is pointed out, the scarcity of historical climate data makes climate reanalysis estimates before 1970 “largely uncertain”, while “observed trends cannot clearly be distinguished from natural variability”. Not that this stops mainstream activists such as Clive Cookson at the Financial Times who reacted to a recent two-year downward spike in Antarctica sea ice with the suggestion that the area faced a “catastrophic cascade of extreme environmental events… that will affect the climate around the world”.

Of course a “system in balance” is the last thing a Net Zero-obsessed mainstream wants to hear about. The Antarctica Circumpolar Current is the strongest flow of water on the planet and on March 4th the BBC brought news that it was “at risk of failing”. New research is said to suggest that the current will be 20% slower within 25 years “as the world warms, with far reaching consequences for life on Earth”.

Medieval Warm Period Undeniable, Pronounced In Antarctica And Poland, 2 New Studies Show

Natural cycles drive our climate

The latest video by the Germany-based European Institute for Climate and Energy (EIKE) looks at CO2 and the troublesome Medieval Warm Period, which has long been a thorn for climate alarmists.

Hat-tip: Klimanachrichten

The Medieval Warm Period, the natural warm phase between 700 and 1300 AD, cannot be reproduced climate models because the simulations react primarily to CO2. Back then CO2 was not a factor because its concentration level in the atmosphere was pretty much constant. That’s why people would rather keep the Medieval Warm Period quiet.

But the facts speak for themselves. Two studies now add further pieces to our knowledge of the medieval climate.

Antarctica

In October 2023, a paper by a team of researchers led by Zhangqin Zheng from the University of Science and Technology of China in Hefei was published in the journal Quaternary Science Reviews. It deals with historical changes in the Adélie penguin population in the Ross Sea region of Antarctica and their climatic influences.

These natural processes are still taking place today and have by no means ended with the start of the CO2 increase.

Poland

The other study comes from Poland. The research group led by Rajmund Przybylak from Nicolaus Copernicus University in Toruń, Poland, published their work in the journal “Climate of the Past” in November 2023. The article presents current findings on climate change in Poland for the period from 1000 to 1500 AD. This period also includes the Medieval Warm Period. The scientists first studied all available quantitative climate reconstructions that have been produced for Poland in the last two decades. They also produced four new reconstructions using three dendrochronological series and an extensive database of historical source data on weather conditions. The growth of conifers in the lowlands and mountains of Poland depends on the temperatures in the cold season, especially in February and March. All available reconstructions based on dendrochronological data refer to this time of the year. Summer temperatures were reconstructed using biological proxies and documentary evidence. However, the latter are limited to the 15th century. The winter temperature was used as a proxy for the annual temperature proxies, instead of the usual use of the summer temperature.

The Medieval Warm Period probably occurred in Poland from the late 12th century to the first half of the 14th or 15th century. All analyzed quantitative reconstructions indicate that the Medieval Warm Period in Poland was comparable or even warmer than the average temperature in the period 1951-2000.
