The year 2024 was marked by significant climate developments, with global average temperatures rising to 1.12°C above pre-industrial levels for the first time. This one-off spike in temperatures, however, does not indicate a crossing of the critical 1.5°C threshold, which requires sustained warming over decades. As natural factors such as the El Niño Southern Oscillation shift, a temporary cooling is anticipated next year, but the long-term trend of rising temperatures driven by CO2 concentrations continues to be a concern.
CO2 Emissions and Global Impact
In May, atmospheric CO2 concentrations reached a new peak at 46.9 PPM, reflecting the ongoing increase in carbon emissions, which are projected to hit 37.4 billion tons from energy-related sources. Despite these troubling figures, there are emerging positive trends. Notably, CO2 emissions in the EU fell significantly, and the U.S. saw a slight decrease, contrasting with substantial increases in India and modest rises in other parts of the world. China, a major emitter, reported a minimal 0.2% increase in emissions, with predictions suggesting a potential decline due to its aggressive decarbonization efforts.
Renewables and Energy Transition
This year saw a significant surge in renewable energy use, with over 30% of global electricity now coming from renewable sources. The International Energy Agency (IEA) suggests that global electricity emissions have peaked and will begin to decline, driven by the growth of renewables and a shift away from coal. In a notable development, the UK shut down its last coal-fired power plant, marking a significant milestone in its energy transition.
International Climate Negotiations
International climate negotiations faced challenges, with COP 16 in Colombia ending in disarray, and talks for a global plastics treaty collapsing in South Korea. Despite these setbacks, over 100 countries expressed support for reducing plastic production. COP 29 in Abu Dhabi was marked by organizational issues and a dramatic walkout by developing nations over climate finance, leading to a chaotic conclusion.
Predictions for 2025
Looking ahead to 2025, several key predictions have been made. Global temperatures are expected to fall below 1.12°C due to the La Niña phase. However, concerns remain about the potential impact of political changes on climate policies, particularly in the U.S. where federal climate initiatives are anticipated to be rolled back. On the international stage, countries like China are expected to position themselves as leaders in climate action.
The year 2024 highlighted both the challenges and progress in addressing climate change. While emissions reductions are still desperately needed, the advancements in renewable energy and the potential for significant global leadership in climate action offer a glimmer of hope for the future.
