    Introduction

    • The year 2023 witnessed alarming signs of climate change, from record-breaking summer temperatures to shrinking Antarctic sea ice and extreme weather events across the globe.
    • Despite the overwhelming scientific consensus on climate change, there remains confusion and misinformation on this critical issue.

    Is the Earth Becoming Warmer?

    • Temperature Measurement: Temperature measurements since the late 1880s show global warming trends. Satellite data confirms an increase of at least 1.1 degrees Celsius since 1880.
    • Indirect Verification: Analyzing natural indicators like tree rings and ice cores. Observing effects such as warming oceans, shrinking ice cover, and rising sea levels. Multiple monitoring systems enhance confidence in global-scale warming.
    • Acceleration of Warming: Recent decades witness unprecedented rapid warming. The majority of warming observed since 1975. 2022 marked the 46th consecutive year of temperatures above the 20th-century average.

    Role of Human Activities

    • Natural Factors: Throughout Earth’s history, natural factors like solar variations and volcanic activity influenced climate.
    • Current Acceleration: However, natural factors exert too little influence and operate too slowly to account for recent rapid warming, as acknowledged by NASA.
    • Greenhouse Gases: The primary driver of global warming is the increasing concentration of greenhouse gases, particularly carbon dioxide (CO2), methane (CH4), and water vapor.
    • Human Influence: Since the Industrial Revolution, human activities, especially the burning of fossil fuels, have released substantial greenhouse gases into the atmosphere.
    • Unprecedented Change: Changes that would typically occur over hundreds of thousands of years are now happening within decades.

    Overwhelming Evidence

    • Scientific Consensus: The Intergovernmental Panel on Climate Change (IPCC) has stated that “human influence on the climate system is clear and growing.”
    • Unprecedented Warmth: 2022 marked the 46th consecutive year with global temperatures exceeding the 20th-century average, with the last nine years ranking among the warmest.

    1.5 Degree Celsius Threshold

    • Paris Agreement: 195 countries pledge to limit warming to “well below 2 degrees Celsius” and aim to limit the increase to 1.5 degrees Celsius.
    • Baseline Year: Pre-industrial levels based on measurements from 1850 to 1900, providing a reliable historical reference.
    • Reason for 1.5 Degrees: Scientific consensus: 1.5 degrees is a defense line against severe climate impacts. It avoids extreme and irreversible consequences associated with 2 degrees warming.
    • Continuous Improvement: Lowering the target reduces climate risks further. Science supports aiming for the lowest possible temperature increase.

    Consequences of Breaching the Threshold

    • Increased Extreme Weather: More frequent and intense heavy precipitation. Elevated drought intensity and frequency in some regions.
    • Warmer Oceans: Higher number of strong hurricanes with rapid strengthening.
    • Intensified Wildfires: Longer-lasting and more intense wildfires.
    • Rapid Sea Ice Melt: Accelerated sea-level rise.
    • Emerging Consequences: Many of these impacts are already underway. Breaching the threshold exacerbates these effects.

    How Close Are We to Breaching the Threshold?

    • WMO Warning: World Meteorological Organisation (WMO) warns of a 66% chance of crossing the 1.5-degree limit between 2023 and 2027.
    • Hottest Year: 2023 declared the hottest year on record, 1.48 degrees Celsius warmer than pre-industrial levels.
    • Daily Fluctuations: Daily temperatures occasionally exceed 1.5 degrees Celsius, but long-term trends are the focus.

    Conclusion

    • The evidence of climate change and global warming is undeniable.
