<p>New Delhi: Atmospheric carbon dioxide levels reached 420 parts per million in 2023, the highest in the last 8,00,000 years, according to the World Meteorological Organization's (WMO) State of the Climate report published on Wednesday.</p>.<p>The report said long-term global warming is currently estimated to be between 1.34 and 1.41 degrees Celsius compared to the 1850-1900 baseline.</p>.<p>It said that tropical cyclones, floods, droughts and other disasters in 2024 led to the highest number of new displacements recorded in the past 16 years. These events also worsened food crises and caused massive economic losses.</p>.Climate change: World in worse situation because of inaction, says UN climate science panel chief.<p>Carbon dioxide levels in 2023 (the latest year with complete global data) were 420.0 ± 0.1 parts per million (ppm), 2.3 ppm higher than in 2022 and 151 per cent of the pre-industrial level (1750). The WMO said 420 ppm corresponds to 3,276 gigatonnes (or 3.276 trillion tonnes) of carbon dioxide in the atmosphere.</p>.<p>The report said the past 10 years (2015-2024) were the warmest on record, with each of the last eight years setting new highs for ocean heat content.</p>.<p>Around 90 per cent of the extra heat trapped by greenhouse gases is absorbed by the ocean, warming it and affecting marine life, weather patterns and sea levels.</p>.<p>In 2024, global mean sea level was the highest since satellite records began in 1993.</p>.<p>The rate of sea level rise from 2015-2024 was double that of 1993-2002, increasing from 2.1 mm per year to 4.7 mm per year, the UN weather and climate agency said.</p>.'Global weirding' hits Mumbai, Lucknow as cities world over suffer 'climate whiplash'.<p>It said that the period 2022-2024 recorded the most negative three-year glacier mass balance.
