The world has witnessed an unprecedented surge in marine heatwaves (MHWs) over the past two years, with a staggering 240% increase in the number of MHW days during the summers of 2023-2024 compared to historical records. A recent study published in Nature Climate Change warns that nearly 10% of the world's oceans have recorded the highest sea surface temperatures (SSTs) ever observed four times higher than the historical annual average. The primary driver behind this alarming trend is human-induced climate change, which has been further amplified by El Niño a natural climate phenomenon in the Pacific Ocean known for warming sea surface temperatures and record-low global cloud cover. Escalating Ocean Heatwaves and Their Devastating Consequences Marine heatwaves occur when ocean tem...

Atmospheric carbon dioxide concentrations reached a new high of 422 parts per million in 2024, according to the European Union's Copernicus Climate Change Service (C3S). This milestone follows another record-breaking year for global temperatures, increasing pressure on policymakers to take more aggressive action against climate change. Recent studies indicate that global warming may be accelerating beyond previous estimates. The world may have already reached 1.5°C above pre-industrial temperatures, a critical threshold for triggering extreme and irreversible climate impacts. Research published in Nature Geoscience in November 2024 used 2,000 years of Antarctic ice core data and found warming at 1.49°C in 2023, based on a longer pre-industrial baseline.
