These numbers and these questions appear From the report It was published on June 5 by a European team of about fifty scientists responsible for publishing monitoring of “global climate change indicators” each year. Their new data estimates the year 2023.
The “excess heat” we're talking about here is what experts call the Earth's “energy balance,” or more accurately, in this case, its “energy balance.” Energy imbalance “Basically, this seems like a simple calculation: the amount of energy that 'enters' our planet – mainly in the form of solar radiation – compared to that which 'goes out' – the fraction of that radiation that reflects off the Earth's surface and returns to Earth. Space. With Accumulating greenhouse gases in the atmosphere, a portion of the heat that “gets out” in normal times remains trapped in today's atmosphere—hence the expression “narrow effect.”

Much of this excess heat accumulates in the oceans, Hence the anxiety This sparked a new report published in the journal Earth System Science Data. This is because the oceans, although efficient, do not have an unlimited capacity to absorb heat. It is estimated that they have absorbed 90% since the beginning of the industrial era in the nineteenth century. But they are franticjudging by accumulated ocean surface temperature records: according to published data previous JanuaryThe planet's oceans broke a new record in heat absorption in 2023… for the fifth year in a row. in study Published December 2023 Four ocean experts say the rate of ocean warming has accelerated over the past 20 years.
In the 2023 update of their “global” indicators, European researchers talk about it in numbers: between 1974 and 1993, the Earth’s energy imbalance was 0.42 watts per square meter, but from 2004 to 2023 it rose to 0.87 watts per square meter .
This joins The latest report is the IPCC Which estimated in 2021 that this imbalance in the period 2006-2018 had reached 0.79 watts per square meter. The drawback of the IPCC reports is that every time they lag a little behind this type of indicators, because their writing must be based on the consensus reached by experts in any field.
