I posted this 2 years ago. After which we experienced 2 years of 1.6°C above the Paris' pre-industrial (1850-1900) baseline. We expected a big jump in global warming because greenhouse gas emissions keep increasing, aerosols decreased and Earth's Energy Imbalance had doubled.

This might be the year everything changes, as those who don't count joules and radiative fluxes are too starting to feel the heat from reducing air-pollution. Many great scientists have tried to inform on this in the past decades (e.g. James Hansen, James Lovelock, Paul Crutzen and Veerabhadran Ramanathan). Policy makers and media have paid very little attention so far. This was the reason for me to start using my largely dormant Twitter account 3.5 years ago. To create awareness about rapid warming from rapidly reducing air pollution. There's mainly been a small crowd of 'climate doomers' and slightly anoyed climate scientists to interact with. In the past months this changed, as the additional accumulating heat is starting to surface. My amount of followers has tripled, the graphs we make receive millions of views and media around the world are paying attention. This is bigger than any one of us. We need specialized scientists to assess what this means for changes to monsoon systems, others that look at how ocean and atmospheric currents (might) change and how that could impact melting ice and sea level rise. We need politicians, legal experts and social scientists to learn what is at stake and debate the effects of unintentional and intentional emissions on climate, not just health and the environment. There are no easy choices in this. How much warming will the world except? And how fast can the rate of warming be until we are unable to adapt? When will we learn how high our dikes really need to be? How extreme will droughts get? How many people will lose their homes and need to move to greener pastures? Be it a locally overflowing refugee camp or to another country? Will we have the stability of global governance to face these accumulating challenges? Uncertainties are very large, which might be the main problem. We don't know how bad it will get, and anyone who tells you one way or another is lying. The precautionary principle tells us we have the duty to act. For ourselves, for our children and for strangers we will never meet. We are the most adaptable species known to ever have existed. I believe that with a more thorough understanding of our planet, humanity could become a beneficial force to life on Earth. If we soon aquire collective will to do so.

Remember when folks were saying 2023 was a merely strong El Niño? (It wasn't!) We're about to find out what a record Super El Niño looks like, combined with the equivalent of the global CO₂ concentration in doubling in a geological instant.

Ocean temperatures in the key El Niño monitoring region have now set records for a month straight and are about 2˚C above average — the threshold for a super El Niño. The current streak is now just days away from the 40-day record set during the historic 1997 event.

@ChrisGloninger You're calling Wielicki a climate scientist? He's a geologist/oil guy and a serious grifter.

A climate scientist blocked me for posting peer-reviewed citations under his misinformation. This week he was put in charge of the National Climate Assessment. The block button was never about being wrong. It was about not wanting the record corrected. Now he controls the record.

This happens on both sides, unfortunately. Some people don't like data that object their false narratives.
Chris Colose@CColose

@ChrisGloninger It’s a common tactic among the disinformation circle to block or ignore anyone who actually knows anything, since they know sunlight is the best disinfectant. They much prefer advertising their nonsense inside a bubble.

The Northern Hemisphere mid-latitude Sea Surface Temperature increase is the same magnitude of a trilopical El Niño peak and most likely permanent, as that's where most of the shipping desulphurization and therefore the net/aerosol radiative forcing increase happened.

An El Nino started which seems to become a strong one.  I made comparisons with some past El Ninos. With help from global warming, the Nino regions may get really warm. Data source: NASA Goddard Institute for Space Studies

Breaking News! Code: UFB!!! It's official! The "Super El Nino" has begun, with Niño 3.4 sea-surface temperatures now 2.0°C (3.6°F) above the 1991-2020 baseline. The Climate 8-ball is getting racked.

@LeonSimons8 Global temperature anomalies generally lags Nino 3.4 SST anomalies by roughly 4 months.

"This repetitive pattern could nudge El Niño's peak intensity toward the higher-end scenarios." That's the higher-end of these already record high scenarios.. El Niño peaking at 4.5°C above the 1991-2020 average would be diabolical, to use the scientific term.

Westerly wind burst after westerly wind burst after westerly wind burst. In the equatorial Pacific, these ocean heat-shifting winds show no signs of easing in the months ahead. This repetitive pattern could nudge El Niño's peak intensity toward the higher-end scenarios.

Going back to 1981, sea surface temperatures in the Niño 3.4 region have only been higher than present once before: November 2015. Other El Niño emergent years (2023; 1997; 1982) also saw very high November temperatures slightly above their summer peaks. Will we see record high temperatures in this region in November?

To be fair, this is already diabolical.. The global weather impacts will materialize over the next 3 months, as it takes time for the tropical Pacific anomalous surface heat to spread around the globe.
World Climate Service@WorldClimateSvc

Niño3.4 SSTs are now 2°C above the 1991-2020 normal, according to OISSTv2.1 data. In the OISST history since 1982, the previous earliest this threshold was crossed was August 30, 1997.
