In 2024, the World Meteorological Organization reported alarmingly high global temperatures, with levels surpassing 1.5°C above pre-industrial averages. Greenhouse gas concentrations rose to their highest in 800,000 years, leading to extensive extreme weather events worldwide. Flooding, droughts, and record heat affected various regions, underlining the urgent need for action against climate change and a transition to clean energy sources.
Climate change remains the most critical challenge confronting humanity in this century, making it essential to monitor ongoing climate transformations. The World Meteorological Organization (WMO) has released its annual State of the Climate report, revealing that 2024 marked a significant temperature milestone, registering more than 1.5°C above pre-industrial levels for the first time. Notably, atmospheric greenhouse gas concentrations have reached their highest levels in 800,000 years, compounding the effects of climate change.
The WMO report highlights alarming trends echoing across the globe. The year 2024 is noted as the warmest on record, with global temperatures averaging 1.55°C above historic averages observed between 1850 and 1900. This unprecedented spike in temperature signals the consequences of greenhouse gas emissions, as evidenced by the record-setting warmth of 2023 and 2024, both significantly hotter than previous years. Several factors, including a strong El Niño event and reduced shipping pollution, contributed to these temperature increases.
In addition to rising temperatures, other critical markers related to climate change are breaking records. Carbon dioxide levels reached 427 parts per million, and sea levels rose by an alarming 11 centimeters since the early 1990s. The oceans are experiencing unprecedented temperature increases, while seasonal sea ice is diminishing rapidly, shown by shrinking levels around the Arctic and Antarctica. All regions, particularly tropical areas, experienced considerable heat in 2024.
Extreme weather events have also become more frequent, disproportionately affecting regions like North America, Europe, and Australia. Notable disasters include Hurricane Helene in the United States and catastrophic flooding in Spain. However, severe events in Africa, South America, and Southeast Asia received less media attention, despite causing significant fatalities and displacements. Instances such as Super Typhoon Yagi and Cyclone Chido exemplify the widespread impact of climate-induced scenarios.
The consequences of climate change and extreme weather are manifesting in dire situations, from unusual flooding in arid regions like the Sahara to a century-long drought impacting southern Africa. This diverse array of climate events has displaced more individuals globally than any year since 2008. The role of climate change varies, with definitive influences observed in some disasters, such as Hurricane Helene, while its contributions are less evident in others.
The report serves as a stark reminder of the failure to address climate change adequately. Despite understanding the mechanisms of greenhouse gas-induced warming for over a century, emissions continue to rise at alarming rates. The time to act is critical, as every increment of global warming incurs further damage. Achieving net-zero emissions is essential to mitigate the escalating crisis and secure a safer future for both people and the planet.
The 2024 State of the Climate report reveals a significant escalation in global temperatures and greenhouse gas concentrations, highlighting the urgent need to combat climate change. Record-breaking heat has led to devastating extreme weather events worldwide, with severe impacts particularly felt in vulnerable regions. The rising emissions indicate that a major shift toward clean energy and fossil fuel reduction is necessary to prevent worsening conditions. Moving forward, sustained efforts to achieve net-zero emissions will be crucial to address this imminent crisis and protect our environment.
