How long do we have?
The March 2019 temperature is in line with an earlier analysis that 2019 could be 1.85°C warmer than preindustrial and that a rapid temperature rise could take place soon, as illustrated by the image below.
A catastrophe of unimaginable proportions is unfolding. Life is disappearing from Earth and all life could be gone within a decade. At 5°C of warming, most life on Earth will have disappeared. When looking at near-term human extinction, 3°C will likely suffice. Study after study is showing the size of the threat, yet many people seem out to hide what we're facing.
Above image asks 'How long do we have?' The image is created with NASA LOTI data, adjusted 0.78°C to reflect a 1750 baseline, ocean air temperature and higher polar anomaly. Trends are added based on 1880-2019 (purple) and 2000-2019 data (red). The long-term purple trend points at 2025 as the year when 3°C rise from preindustrial could be crossed, while the red trend that focuses on short-term events shows how a 3°C rise from preindustrial could be reached as early as in 2020.
The chart below shows elements contributing to the warming, adding up to a rise of as much as 18°C by 2026.
