• This two-part Mongabay mini-series examines the current status of the climate emergency; how world leaders, scientists and the global community are responding; and what may lie ahead as the world warms beyond the crucial 1.5° Celsius (2.7° Fahrenheit) limit established in the Paris Agreement 10 years ago.
• The unprecedented warming that began in 2023, continued through 2024 and extended into 2025 has caused surprise and alarm. Scientists still don’t fully understand the cause, but some fear it signals the global climate is transitioning into a new state of accelerated warming.
• 2024 was the first full calendar year to exceed 1.5°C above preindustrial levels. A recent projection finds it likely Earth will see a 20-year average warming of 1.5°C by as early as 2029, exceeding a key Paris accord goal and which could trigger self-perpetuating changes pushing Earth’s climate into a less habitable state.
• In January, President Trump withdrew from the Paris Agreement, signaling that the U.S. will not lead on climate action. To date, nearly all the world’s nations have fallen far short of what is needed to stay within 1.5°C. As countries submit new U.N. carbon commitments, some fear the U.S. reversal will ripple around the world.
