Global warming has been a pressing issue for over a century, with data showing a significant increase in human-induced warming from 1880 to 2020. The annual Indicators of Global Climate Change report, published for the second year, reveals that human-induced warming has risen to 1.19°C over the past decade (2014-2023), up from 1.14°C measured between 2013 and 2022. In 2023 alone, human activity caused warming to reach 1.3°C, making it the hottest year in history.

The report also highlights the remaining carbon budget as of early 2024, estimated to be between 100 and 450 gigatons, with a central estimate of 200 gigatons. This budget represents the amount of carbon dioxide that can be emitted without surpassing the 1.5°C threshold compared to pre-industrial levels, as outlined in the Paris Agreement. However, since 2020, carbon dioxide emissions have increased, leading to a rise in global warming.

Prof. Piers Forster from the University of Leeds, one of the report’s authors, emphasized the need for urgent action to address the escalating levels of global warming. He stated that despite efforts to slow the rise in greenhouse gas emissions, global temperatures are still increasing at an alarming rate. The report indicates that human-induced warming is rising at approximately 0.26°C per decade, with a high greenhouse gas emission rate of 53 billion tons of carbon dioxide per year.

The impact of these emissions is evident in the Earth’s energy balance, with unprecedented flows of heat into the oceans, ice caps, soils, and atmosphere. Prof. Forster highlighted that fossil fuel emissions are the main driver of climate change, but other sources of pollution from cement production, farming, and deforestation also contribute to warming. He stressed the importance of rapidly reducing greenhouse gas emissions to limit global warming and build more resilient societies.

The report’s findings underscore the need for accelerated climate policy plans to reduce polluting emissions and adapt to future climate impacts. Decision-makers are urged to fulfill their commitments under the UN Framework Convention on Climate Change by 2025 to address the escalating threat of global warming. With the information gap created by the delayed IPCC assessment, it is crucial to stay informed and take decisive action to combat climate change.
