Climate crisis disrupted the natural balance of the planet: Humanity stopped the next ice age

The natural climate cycle that the Earth has followed for millions of years has experienced an irreversible break due to human-induced global warming. The new research, conducted jointly by climate scientists at Columbia University and the University of Colorado Boulder and published in the respected science journal Science, documented that the new glacial period, which the planet was naturally preparing to enter, was stopped by sudden temperature increases in the 20th century. Scientists announced that the use of fossil fuels and the accumulation of greenhouse gases in the atmosphere have postponed the Earth's geological calendar by at least several hundred thousand years.

Geologically, the Earth, which lived in a warm "interglacial" period that started approximately 11,700 years ago, started to cool down again 2,000 years ago and began to give signals of a new glacial period. The research team mapped the historical movement of glaciers by examining plant remains and radioactive beryllium-10 isotopes in rocks within the Barnes Ice Cap on Baffin Island in Nunavut, Canada.

Measurements revealed that the ice sheet began to expand again 2 thousand years ago and continued its growth steadily until 60 years ago. However, global warming, which has accelerated in the last half century, has caused the growing glaciers to suddenly melt. Geochemist Nicolás Young, one of the authors of the study, emphasized that while the system was moving towards a new glaciation with its normal functioning, it was stopped by human influence.

University of Wisconsin-Madison glaciologist Prof. wrote the evaluation article accompanying the research. Dr. Shaun Marcott stated that current climate data makes a future ice age unlikely for hundreds of thousands of years.

Marcott stated that humanity has now become a dominant geological force that frustrates the planet's fundamental geological cycles, rather than being a species that merely pollutes the environment. It was noted that how many glacial cycles will be skipped in the future directly depends on the speed at which humanity gives up fossil fuels and its carbon emission preferences.

Scientists point out that although postponing the next ice age may seem positive at first glance, it poses serious risks for the ecological balance of the planet. It is stated that biological and physical systems that have evolved with glacial cycles in the last 2 million years of geological history will have difficulty adapting to this sudden deviation.

Experts warn that the suspension of natural cycles will trigger permanent and unpredictable changes in many vital systems, from ocean currents to global climate zones.
