Heatwave hits Antarctica ♨️ #shorts


According to the @worldmetorg, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region.

    1. For the majority of the Earth's existence, polar ice caps were non-existent, and the average global temperature was notably higher, ranging from 8°C to 15°C above contemporary levels.

    2. The Earth is presently situated within the Quaternary Glaciation, which is a glacial period that commenced approximately 2.58 million years ago.

    3. The termination of the last ice age approximately 12,000 years ago marks the onset of the current episode of global warming, which marks the advent of the Holocene interglacial period. The present-day warm climatic conditions are limited in duration, as interglacial periods exhibit a temporal range of 20,000 to 60,000 years.

    4. During the Early Holocene period, which occurred between 12,000 and 7,000 years ago, there was a significant rise in sea level. According to scientific research, the global sea level rose by approximately 197 feet (60 meters) during this time period. Interested individuals may refer to the scientific literature to learn more about this phenomenon, which is commonly known as the Early Holocene Sea Level Rise.

    5. Climate is a dynamic and constantly changing system that exhibits variations in response to a variety of factors. The notion of a static, unchanging climate is not supported by scientific evidence. For those seeking to expand their knowledge on the subject of climate variability, a study of past climatic fluctuations such as The 8.2 Kiloyear Event, The Little Ice Age, and The Year Without a Summer (1816) may prove insightful.

    6. The long-term evolution of climate is subject to a multitude of factors. Among these factors, human activity has been determined to exert a substantially lesser impact compared to other factors, such as solar activity, the Milankovitch Cycles, or volcanic activity, which have been found to operate on multiple orders of magnitude greater in their influence.

    7. Chaos theory is a highly effective mathematical tool that is utilized to describe the behavior of complex systems. One of the most fascinating aspects of chaotic systems is their sensitivity to initial conditions, which can result in unpredictable and seemingly random behavior. This sensitivity is not restricted to complex systems, as even simple ones can display chaotic behavior, as demonstrated by the well-known example of the double pendulum. The climate system is a tremendously complex system, consisting of a large number of variables that contribute to its highly nonlinear nature. Given the intricate interplay of numerous factors, ranging from atmospheric conditions to ocean currents, it is hardly surprising that climate models are renowned for their unpredictability. Even the slightest perturbations can result in significantly different outcomes. Furthermore, the difficulty of accurately predicting the evolution of the climate is compounded by the challenge of effectively monitoring weather patterns due to the lack of appropriate technology and instrumentation.

    8. Water vapor accounts for 95% of all greenhouse gases present in the Earth's atmosphere.

    9. The geologic epoch of Hirnantian Glaciation was characterized by a substantially higher concentration of atmospheric carbon dioxide, estimated to be tenfold greater than the contemporary era.

    10. Carbon dioxide (CO₂) cannot be considered a pollutant in any sense according to scientific understanding. The vast majority of atmospheric oxygen, which is essential for most forms of life on Earth, is generated as a byproduct of the process of photosynthesis, wherein CO₂ is converted into glucose and water by living organisms using light energy. Moreover, CO₂ finds widespread usage in several industrial and medical applications, such as the production of carbonated beverages in the food industry and in laparoscopic surgeries performed in hospitals. Therefore, based on scientific knowledge and understanding, CO₂ is not appropriately classified as a pollutant.


    Despite extensive research on the effects of climate change, significant uncertainty remains concerning the impacts on humanity. The complex nature of the Earth's climate system and the limited understanding of its mechanisms make it challenging to draw definitive conclusions about the potential dangers of the current climate trajectory. To address this issue, it is crucial to consider diverse scientific opinions. Notably, some highly respected physicists, including Nobel laureate Ivar Giaever and Freeman Dyson, have expressed skepticism about the man-made climate change hypothesis. These experts have labeled global warming as "pseudoscience" and have characterized climate change predictions as "absurd." As scientific investigations require empirical evidence and rigorous testing, it is crucial that expert opinions are considered in open and honest dialogue. While consensus may be valuable, it is important to recognize that science is not a democratic process and requires a continuous and objective examination of data to understand the complexities of climate change. As Carl Sagan put it:

    To mitigate the influence of confirmation bias, it is prudent to actively seek out opposing viewpoints that diverge from one's preconceived beliefs and perspectives. The act of engaging with dissenting opinions may yield valuable insights.
