The above image illustrates the threat of a huge temperature rise. The red trendline warns that the temperature could increase at a terrifying speed soon.

The global surface air temperature was 13.87°C on March 8, 2025, the highest temperature on record for this day. This is the more remarkable since this record high temperature was reached during a La Niña. 

The shading in the image highlights the difference between El Niño conditions (pink shading) and La Niña conditions (blue shading). An El Niño pushes up temperatures, whereas La Niña suppresses temperatures. We're currently in a La Niña, so temperatures are suppressed, but this is predicted to end soon. NOAA predicts a transition away from La Niña to occur next month.
The transition from La Niña to El Niño is only one out of ten mechanisms that could jointly cause the temperature rise to accelerate dramatically in a matter of months, as described in a previous post. Another one of these mechanisms is the increase in greenhouse gas concentrations. 

Increase in carbon dioxide 
The daily average carbon dioxide (CO₂) at Mauna Loa, Hawaii, was 430.60 parts per million (ppm) on March 7, 2025, the highest daily average on record. To find higher levels, one needs to go back millions of years. 

DJ, The atmosphere is changing-CO2, methane, water vapor are containing more warmth. 

Carbon dioxide typically reaches its annual maximum in May, which means that even higher daily averages can be expected over the next few months. The image below shows that this reading of 430.6 ppm at Mauna Loa is way higher than the highest daily averages recorded in 2024. 
-
The annual increase in CO₂ at Mauna Loa, Hawaii, is accelerating, as illustrated by the image below. 
-
A trend, based on 2015-2024 annual data, points at 1200 ppm CO₂ getting crossed in the year 2032, as illustrated by the image below.
The above trend illustrates that the clouds tipping point could get crossed in early 2032 due to rising CO₂ alone, which on its own could push temperatures up by an additional 8°C. The clouds tipping point is actually at 1200 ppm CO₂e, so when growth of other greenhouse gases and further mechanisms is taken into account, the tipping point could be crossed much earlier than in 2033.

Increase in methane

Methane in the atmosphere could be doubled soon if a trend unfolds as depicted in the image below. A rapid rise is highlighted in the inset and reflected in the trend. 

The trend points at a doubling of methane by March 2026. If the trend would continue, methane concentrations in the atmosphere would by September 2026 increase to more than triple the most recent value, and would increase to more than fourfold the most recent value by the end of 2026.

A rise like the one depicted in the trend could eventuate as rising ocean heat destabilizes methane hydrates contained in sediments at the seafloor of the Arctic Ocean. The temperature rise in the Arctic would accelerate since the methane would have a huge immediate impact on temperatures over the Arctic and cause depletion of hydroxyl, of which there is very little in the atmosphere over the Arctic in the first place. Such a rise in methane would also dramatically increases in tropospheric ozone and in stratospheric water vapor. A large increase in methane over the Arctic would also trigger massive wildfires and devastate terrestrial permafrost, resulting in huge amounts of further emissions.

DJ, Methane, CO2 may be realesed in an explosive manner...further increasing "warming".

The heat-energy to melt ice is enough to increase temperature from 0 to 80C...

Even with all best efforts we only may be able-in the short term-limit damage. Like with pandemics-we are allready in a collapse phase. 

Wars only worsen pandemics, climate collapse...still seem to be the major priority for bad "leaders" (for sale)...
