In brief
Projections indicate that 2024 will be the warmest year on record, raising urgent concerns regarding climate change and global policy responses.
Climate experts project that 2024 will likely become the hottest year on record due to unprecedented global temperatures that threaten to exceed the critical 1.5 degrees Celsius above pre-industrial levels. The European Copernicus Climate Change Service reports that human-induced climate change plays a major role, alongside the natural El Niño phenomenon. Only a dramatic temperature drop can prevent a new record, which would symbolize a significant breach of international climate commitments made in the Paris Agreement of 2015.With global average temperatures hovering at record highs during the initial ten months of 2024, scientists point to this alarming trend as a call to action for world leaders, especially with the upcoming COP29 conference in Azerbaijan. Liz Bentley, chief executive of the Royal Meteorological Society, emphasized the need for robust climate policies to limit future warming. The expected average temperature of 1.5 degrees Celsius represents a critical threshold that nearly 200 nations committed to avoiding, in hopes of mitigating severe climate impacts.As the world grapples with the human impact on the climate, the El Niño phase—characterized by unusually warm surface waters in the eastern Pacific—is cited as a key driver behind the initial warmth of 2024. Although this weather phenomenon concluded in April, high temperatures persist, underscoring the urgency of the situation. In the past week alone, global temperature records have been broken every day, according to Copernicus data.Looking ahead, scientists remain vigilant regarding the potential emergence of La Niña, a cooling phase that might temporarily lower global temperatures. However, with escalating greenhouse gas emissions, experts caution that it may only be a matter of time before new temperature records surface. Ed Hawkins, a climate scientist, warns that without aggressive action towards net-zero emissions, the increasing severity of storms and heatwaves will pose dire consequences for populations around the globe.The urgency of the climate crisis casts a shadow over COP29, where global leaders will confront the pressing need for decisive action to safeguard the planet's future.
