A catastrophe of unimaginable proportions is unfolding.

How long do we have?

17 April, 2019



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.

The situation is dire and calls for comprehensive and effective action, as described at the Climate Plan.

As Winds Start To Growl


Late last month, wind patterns over the North Pacific and North America resembled a screaming face.

The Arctic was as much as 7.7°C or 13.86°F warmer than 1979-2000, while in parts of Alaska the temperature anomaly was at the top end of the scale, i.e. 30°C or 54°F above 1979-2000.

On April 14, 2019, wind patterns over the North Atlantic resembled a growling face, as highlighted by the red ellipse on the image.

Temperatures over Greenland were as high as 14.9°C or 58.7°F at 1000 hPa at the spot marked by the green circle.

On the left, the image shows winds at 250 hPa dipping over the U.S., enabling cold winds to descend deep down over North America.

Temperatures in Colorado that day were as low as -13.5°C or 7.6°F, as illustrated by above image.

The map below shows the jet streams stretched out from North Pole to South Pole, while the jet stream is also crossing the Equator over the Pacific Ocean.

Meanwhile, Arctic sea ice extent remains at a record low for the measurements at ads.nipr.ac.jp for the time of year. As the image below shows, Arctic sea ice extent was 12.9 million km² on April 14, 2019.

The situation is dire and calls for comprehensive and effective action, as described at the Climate Plan.
