Global Cooling Is Under Way

And you expect to stave off climate change by just restricting CO2?

Huh don't know Emission spectra. Gee how surprising

*chuckle*

What are absorption spectra? (IF you knew these things, you'd already know the answer to your questions, dear)

What was the answer to my question, again?
Book learning isn't as impressive without some logic to back it up.

What is the d13c/12c isotopic ratio?

(HINT: If you knew these things, you'd already have your answer....)

Guess you won't answer my simple question. You know, book learning isn't as effective without logic to back it up.

LOL I'm giving you the answers --you're just too ignorant to know that :lamo

Where is radiative forcing measured, and in what units?
 
Jack Hays said:
Nope. 2017 was cooler than 2016, and 2018 is on its way to being cooler still. With the sun approaching minimum, this should continue for quite a while.

Whoops, you accidentally posted a chart that proves your global cooling prediction wrong.

Which are not, as I recall, in the northern hemisphere. Which eliminates the "regional" claim.
As I said, it's one of many. You'll have to look up the rest yourself.

And represent less than 1% of global surface area. Got any better evidence?

1) Nearly all of the rise is anthropogenic. Atmospheric CO2 stayed pretty stable throughout the Holocene until the industrial revolution, rapidly increasing since 1970.

2)Climate feedbacks .GCRs have largely been found to have little effect (Kulmala et al 2010; Laken, 2013; Krissassen-Totten & Davies, 2013).

Yes, the rise in CO2 is primarily caused by us. The current SST increases would likely put the equilibrium arounf 290 ppm, but the biosphere cannot absorb it as fast as the total sourcing for that equalization, so it will continue to rise.

As for GCR's, I am not one to claim they have a significant effect. I simply have not researched them.

Do you think you are schooling me at all? I am way above your level of knowledge in these disciplines of science. This much is easily seen by everyone who is non-biased and knowledgeable in the sciences.

LOL oh climatologists are "biased"?

[h=2]Abstract[/h]The Medieval Climate Anomaly (MCA) is a well‐recognized climate perturbation in many parts of the world, with a core period of 1000–1200 Common Era. Here we present a palaeotemperature synthesis for the MCA in Africa and Arabia, based on 44 published localities. The data sets have been thoroughly correlated and the MCA trends palaeoclimatologically mapped. The vast majority of available Afro‐Arabian onshore sites suggest a warm MCA, with the exception of the southern Levant where the MCA appears to have been cold. MCA cooling has also been documented in many segments of the circum‐Africa‐Arabian upwelling systems, as a result of changes in the wind systems which were leading to an intensification of cold water upwelling. Offshore cores from outside upwelling systems mostly show warm MCA conditions. The most likely key drivers of the observed medieval climate change are solar forcing and ocean cycles. Conspicuous cold spikes during the earliest and latest MCA may help to discriminate between solar (Oort Minimum) and ocean cycle (Atlantic Multidecadal Oscillation, AMO) influence. Compared to its large share of nearly one quarter of the world's landmass, data from Africa and Arabia are significantly underrepresented in global temperature reconstructions of the past 2,000 years. Onshore data are still absent for most regions in Africa and Arabia, except for regional data clusters in Morocco, South Africa, the East African Rift, and the Levant coast. In order to reconstruct land palaeotemperatures more robustly over Africa and Arabia, a systematic research program is needed.
