I don't know about you guys but I'm feeling it

What is the conversion to Nagasakis

To heat all the water in all the Earth's oceans by 1 degree Celsius it would require the energy equivalent of the detonation of roughly 87 billion Hiroshima-sized atomic bombs.

Besides, there is nothing wrong with the planet, the planet is fine… the people are fucked! Compared to the people, the planet is doing great: been here four and a half billion years, we’ve been here what? 100,000? Maybe 200,000? And we’ve only been engaged in heavy industry for a little over 200 years, and we have the conceit to think that somehow, we’re a threat? That we’re going to put in jeopardy this beautiful little blue-green ball that’s just a-floatin’ around the sun? The planet has been through a lot worse than us: been through earthquakes, volcanoes, plate tectonics, continental drifts, solar flares, sunspots, magnetic storms, the magnetic reversal of the poles, hundreds of thousands of years of bombardment by comets and asteroids and meteors, worldwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages, and we think some plastic bags and aluminum cans are going to make a difference? The planet isn’t going anywhere… we are! We’re going away!

I guess that demonstrates the concept of “a drop in the ocean”, but turning a massacre of civilians into a unit of energy feels crass at best.

It feels like the Earth’s oceans are at a tipping point and can no longer continue to absorb this amount of heat and acidification from the carbonic acid levels increasing when CO2 breaks down. https://www.noaa.gov/education/resource-collections/ocean-co... This year it feels like the ocean is losing its ability to breathe in a sense https://scienceblog.com/the-ocean-stopped-breathing-off-pana... When do we get to full stop on the combustion of fossil fuels to protect humanity’s future?

No I don't get it, can you please provide the measurement in either beaver pelts or football fields.

Oh no, atomic bombs, we all gonna diiiie! Why not two volcano eruptions? Or half a solar flare? Oh I see, fear is the point. What do we need to vote for now? Who should we hate? What tax are you going to ram down our throats? Sheez

The earth would take on heat from the sun in any case. Is this additional heat?

The short term solution to this problem may be to burn gigatons of liquid sodium in the exhaust of jet engines in the stratosphere.[1] If you burn liquid sodium in steam, you end up with sodium bicarbonate particulate of just about the right size to offset global warming.[2] [1] https://ntrs.nasa.gov/api/citations/20250000498/downloads/Re...
