Global warming and its evolution in the last decade
Over the past ten years, the world has experienced a significant increase in global warming due to human activity. According to the second annual Global Climate Change Indicators report, average warming has been 1.19 degrees Celsius above pre-industrial levels. This represents an unprecedented increase, at a rate of approximately 0.26 degrees Celsius per decade.
The study, led by the University of Leeds, highlights that this warming is higher than that recorded in the previous period (2013-2022), which was 1.14 degrees Celsius. In addition, an accelerated increase in anthropogenic warming has been observed, reaching 0.26 degrees Celsius per decade during the period 2014-2023.
The impact of global warming on ecosystems
Global warming caused by the emission of greenhouse gases has a significant impact on all ecosystems on the planet. The report mentions that unprecedented thermal flows have been recorded towards the Earth’s oceans, glaciers, land and atmosphere. This affects the energy balance of the planet and has consequences for life in all its forms.
The year 2023 and its heat records
The year 2023 was especially notable in terms of global warming. According to the annual Global Climate Change Indicator report, it was officially the warmest year on record since 1850. During that year, warming caused by human activity reached 1.3 degrees Celsius, although total warming was 1.43 degrees Celsius. . This demonstrates the natural variability of the climate, especially considering the impact of the El Niño phenomenon.
The impact of warming on the oceans
In addition to global warming, the oceans also face other threats such as oxygen loss and acidification. A study published in the scientific journal AGU Advances highlights that approximately one fifth of the world’s ocean surface is especially vulnerable to these threats, all of them driven by human activity. This includes the burning of fossil fuels and deforestation.
