Climate Crisis Deepens: WMO’s Dire Warning for the Coming Years

The world meteorological organization (WMO) released its “Global Annual to decadal climate update 2023-2027” report. The report asserts that the global temperature will likely surge to record levels in upcoming years, fuelled by the greenhouse gas emissions and naturally occurring El Nino event.

WMO said that the annual mean temperature between 2023 and 2027 will be 1.1-1.18 degree Celsius higher than the baseline pre-industrial levels (1850-1900). And by 2027 average will exceed 1.5 degrees, a critical point beyond which there is no return. However, the report does not mean that the temperature will permanently exceed the 1.5-degree level specified by Paris Agreement which refers to long-term warming over many years.

The Paris Agreement

The Paris Agreement is a landmark achievement accord that was adopted in 2015 to address climate change and its negative impacts. It aims to reduce greenhouse gas emissions to limit the rise in global temperature by 2 degrees Celsius above the pre-industrial levels. While aiming to pursue means to limit the increase to 1.5 degrees by 2100. The baseline of the preindustrial level is chosen as human-induced Greenhouse emissions started after industrialization.

Extreme weather events linked to the global rise in temperatures

Countries like Ethiopia, Nigeria, South Sudan, Somalia, Yemen, and Afghanistan are facing acute food shortages leading to food crises and malnutrition. Climate change and natural factors like cyclones, droughts, and floods across the globe contribute to crop failures and an increase in pest attacks. The heat waves in India and Pakistan in 2022 also resulted in crop failures and floods in central and southern parts of Pakistan displacing around 8 million people within the country.

Aquatic and terrestrial ecosystems have also not been immune to climate change. The population of migratory bird species has declined in Sub-Saharan Africa. Additionally, the rise in Global temperature above 1.5 degrees can prove lethal for coral reefs which are already prone to bleaching. According to WMO extreme weather anomalies have led to a total loss of $4.3 trillion in the past fifty years and over 2 million deaths.

The release of the WMO’s “Global Annual to decadal climate update 2023-2027” report brings concerning news of record-breaking global temperatures in the coming years. The report highlights the urgent need to address greenhouse gas emissions and the impact of natural events like El Nino. Extreme weather events, food shortages, and ecosystem disruptions are clear signs of the consequences of climate change. It is crucial for nations to take immediate and decisive action to mitigate these effects and strive to limit global warming to prevent irreversible damage.
