The CO2 problem in six easy steps (2022 Update)

Real Climate

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).

The Rise and Fall of the “Atlantic Multidecadal Oscillation”

Real Climate

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.

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. The raw trend in the (then Version C) MSU2R record from 1979-1993 was -0.04 Wentz, and M.

Guest Essay: Geothermal Might Have The Answer For Pennsylvania's Clean Energy Needs

PA Environment Daily

Pennsylvania will need to generate more energy in the next two decades, even as the state has set a goal to reduce greenhouse gases 80 percent by 2050 from 2005 levels. In addition to being climate-friendly, its small footprint and ability to meet site-adjacent heating and cooling needs eases pressure on land use and wildlife.

As Soon as Possible

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?

What is happening in the Atlantic Ocean to the AMOC?

Real Climate

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.
