Scientists continue to emphasize how serious global warming and climate change are at every opportunity. The most recent research in this area focuses on the Earth’s 24,000-year temperature change since the last ice age. Marine sediments, which stratified over time and mirrored the climate of the time, were used to reach historical temperature data. From the results obtained, it is understood that the global warming caused by humanity’s own hands has no analogues even in the geological remains of 24 thousand years.
Jessica Tierney, one of the authors of the study and a researcher on world climate history, said, “These 24 thousand-year-old climate records indicate that such high temperatures we are experiencing have never happened before. In addition, it shows that human-induced global warming is progressing faster than any of these periods studied. Similarly, the Intergovernmental Panel on Climate Change announced that we are experiencing the highest temperature increase in the past 2,000 years.
Examples from the last ice age were examined:
The research team, which includes Jessica Tierney, studied the changes in the world’s climate over time by taking 539 samples from coastlines and sea beds around the world. The samples taken included a spectrum from the last ice age, when glaciers covered much of the northern hemisphere, to the present day. It has been observed that the temperature, which has increased gradually and regularly in the last 20 thousand years, has reached an unprecedented rise especially in the last 150 years.
The researchers’ current goal is to collect new samples to study ancient climates that were warmer than the current period. Tierney states that ‘as long as greenhouse gas emissions continue to increase, these old warm climates will be our future’. Emphasizing that there is no time to waste, scientists state that every step to be taken at the moment will go a long way.
