Today, everyone experiences extreme weather. Last year, Texas faced a 50-year flood, glaciers in Iceland melted rapidly, and Jamaica was hit by an unusually strong hurricane. These events are signs that scientists say we need to change our ways quickly.
A recent report by the World Meteorological Organization (WMO) shows that our climate is the most off-balance it has been in history. This imbalance could have lasting effects for centuries.
Key insights from the WMO report reveal that:
- 2015 to 2025 is the hottest decade we’ve recorded.
- Oceans are heating up for the ninth year in a row.
- Glaciers and sea ice are continuing to shrink.
- Extreme weather is increasing, affecting health and causing economic losses.
- Earth’s energy imbalance, caused by greenhouse gases, is at an all-time high.
- Sea levels are rising more quickly than in recent decades.
Antonio Guterres, the UN Secretary-General, emphasizes, “Every key climate indicator is flashing red.” He mentions that our world has seen the hottest 11 years on record, and that signals it’s time to act.
Last year was among the hottest on record, sitting about 1.43 degrees Celsius (2.57 °F) above pre-industrial levels. A climatic pattern called La Niña temporarily cooled some areas, but scientists expect more temperature spikes in 2025 as El Niño returns.
This warming has led to devastating events. In 2025, heatwaves, wildfires, and floods caused thousands of deaths and cost billions. For instance, wildfires in California alone resulted in over $60 billion in damage.
Climate change also brings a rising health risk, including the rapid spread of diseases like dengue fever. Over a billion workers globally face dangerous heat each year, with one-third of the workforce feeling these effects. In fact, a study showed that heat-related deaths increased by 26% in the last decade.
Experts, including Guterres, point out that climate change is not just an environmental issue — it’s a matter of global stability. As resources dwindle, conflicts may rise. Guterres asserts, “Our reliance on fossil fuels destabilizes both climate and global security.”
One alarming factor is Earth’s energy imbalance. This means more energy from the sun is entering the Earth’s systems than is leaving. Greenhouse gases trap this heat, leading to significant changes in ocean temperatures that are now irreversible for centuries. About 91% of this heat is absorbed by the oceans, affecting marine life and ecosystems.
The warming oceans pose risks to millions. Three billion people rely on seafood for protein, but rising temperatures are harming fish populations and coral reefs. More intense storms and rising seas threaten coastal areas and cities around the world.
Glacier loss, particularly in the Arctic and Antarctic, has reached critical levels. They play a vital role in providing water for two billion people. With climate-related disasters increasing, the WMO report stresses the importance of adapting and preparing for extreme weather.
In summary, we face a pressing climate crisis. The data shows that without immediate action, the future of our planet and our stability is at stake. The call to renewable energy and sustainability is louder than ever.
