Rising temperature in absence of El Niño
Critical is the temperature on land, which is after all where people live. The image below shows that in 2025, monthly temperature anomalies (from 1880-1920) on land have fallen from a high of +2.93°C in January 2025 to +1.45°C in July 2025, in line with the temperature suppression that comes with a move into La Niña.

Note that healthy vegetation relies not only on temperature, but also on the presence of good soil, microbes, rain, soil nutrients, pollinators, habitat, groundwater and an absence of toxic waste, pests and diseases.
A 2018 study by Strona & Bradshaw indicates that most life on Earth will disappear with a 5°C rise (see box on the right). Humans, who depend on a lot of other species, will likely go extinct with a 3°C rise, as discussed in the earlier post When Will We Die?

The situation is dire and the precautionary principle calls for rapid, comprehensive and effective action to reduce the damage and to improve the situation, as described in this 2022 post, where needed in combination with a Climate Emergency Declaration, as discussed at this group.
