Key findings:
a) 1.34–1.41°C
b) 1.10–1.25°C
c) 1.50–1.75°C
d) 2.00–2.25°C
- CO2 Levels: Atmospheric carbon dioxide (CO2) concentration reached 420 parts per million (ppm) in 2023, the highest in 800,000 years (8 lakh years), based on comprehensive global data.
- Increase: A 2.3 ppm rise from 2022, making CO2 levels 151% above the pre-industrial baseline of 1750.
- Causes: The surge is attributed to ongoing fossil fuel emissions, significant emissions from vegetation fires, and reduced carbon absorption by forests, worsened by the 2023-24 El Niño event.
- Climate Impact: Global warming is estimated at 1.34–1.41°C above the 1850-1900 average, signaling an intensifying climate crisis.
- Long-Term Outlook: CO2’s long atmospheric lifespan means temperature rises will persist for decades without substantial emission reductions.
Question:
Q.1 What is the estimated range of global warming above the 1850-1900 average, as per the State of the Climate Report 2023, released by the World Meteorological Organization (WMO)?a) 1.34–1.41°C
b) 1.10–1.25°C
c) 1.50–1.75°C
d) 2.00–2.25°C
Answer: a) The global temperature in 2023 was estimated to be 1.34–1.41°C above the 1850-1900 average, highlighting the worsening climate crisis.
