Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).

With the federal government and state of Maryland each having announced within days of each other, the mandated disclosure of greenhouse gas (GHG) emissions, we have received, maybe not surprising, many calls in the last two weeks inquiring “what are GHGs?” greenhouse gas emissions from human activities. emission trends.

These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extra-tropical North Atlantic that play out on 40-60 year timescales (hence the name). Background. any oscillation that was produced has to be internally generated.

Furthermore, if you squinted, you could perhaps convince yourself that there was a correlation to solar activity – well, at least Soon could ( Soon, 2005) ). Indeed, it was still possible to claim in 2000 that Arctic temperatures had not yet exceeded levels in the late 1930s/early 1940s. And which solar reconstruction did he use?

The AMOC has repeatedly shown major instabilities in recent Earth history , for example during the Last Ice Age, prompting concerns about its stability under future global warming, see e.g. Broecker 1987 who warned about “unpleasant surprises in the greenhouse”. We published an early model comparison about this in 2005.

Remember ‘satellite cooling’?]. This was before Wentz and Schabel (1998) pointed out that orbital decay in the NOAA satellites was imparting a strong cooling bias (about 0.12 McNider, "Satellite greenhouse signal", Nature , vol.
