per unit area and in terms of energy, but they are not of

-- https://link.springer.com/article/10.1007%2FBF00140159?LI=true «Karl et al., 1988) has shown that at some «sun belt» cities in the West, the rise of temperature that can be attributed to the urban
heat island is as
much as 0.3 to 0.4 °C
per decade.
Certified Passive House ventilation units have exceptional ECM fan energy performance of no more than 0.45 Watt - hours

``... this robust old station, despite the urban effects, shows that there's been no statistically significant warming in Prague since 1800 (and at most 0.5 °C or so in 200 years, and I haven't subtracted any corrections for the intensification of Prague's urban
heat island which may be as
much as 0.6 °C
per century and which would probably revert the 200 - year trend to a significant cooling!)
The Sun does emit a
much broader spectrum but outside the range of 250 to 2500 nm the amount energy

This has never been demonstrated, there is no evidence at all that it exists, and all the available evidence says the basic

Rather than 50 watts or 2 watts, the amount
heat transferred to the surface, seems
much closer to 0 watts
per square meter.
It could just be a set of rules between how many watts of energy
per square meter of
heating we get between winter and summer and how
much the temperature differs between winter and summer.
So the latent
heat per mole that evaporated water carries away from the oceans surface is
much lower than the calculations state?
It would be helpful if this could be converted to more familiar units, such as watts
per square meter required to generated this
much heat, or the number of degrees Celsius this will raise the water temperature.
Space
heating poses a
much higher risk of fire, death, injury, and loss
per million users than central
