For EM to share his list of evidence.

I have a morbid interest in Entropic Man's links.
So I tried Bing, Google, DuckDuckGo, Dogpile and Ask with the search 30 indicators of climate change. SkepticalScience can manage 10 and the CRU four. I couldn't find any reference to 15 or 30.

Testing

Great! My tablet will work here, but my computer won't. :-( This may take a little while.

This is my parameters list. I' m afraid its grown a little, to three dozen.

Ice

Arctic sea ice extent decreasing
Arctic sea ice volume decreasing
Greenland ice sheet losing mass
Antarctica ice sheet
Arctic snow cover decreasing
Antarctic sea ice extent increasing.
Antarctic sea salinity decreasing
Glaciers retreating

Ocean

Sea surface temperatures increasing
Shallow ( above 700m) ocean heat content increasing
Deep ocean heat content increasing
Sea level rising
PH dropping

Land

Surface temperatures increasing
Droughts increasing
Extreme weather increasing
Permafrost melting

Atmosphere


O2 concentration decreasing
Troposphere temperatures increasing
Stratosphere temperatures decreasing
Water vapour increasing
Jetstreams less stable
High cloud increasing
Low cloud increasing

Energy flows

Imbalance between insolation and OLR
Surface infrared radiation increasing
Downwelling infra-red radiation increasing
15micrometre CO2 band spreading

Biology

Treelines moving to higher altitudes and latitudes
Biome and species ranges spreading to higher latitudes
Longer growing seasons
Vegetation cover increasing


CO2

CO2 content increasing
Carbon 13 decreasing

Methane

Outgassing from Arctic Ocean clathrates
Release from tundra

A little background. I started reading about glacial cycles and pollen analysis in 1971. This grew into an interest in climate and global warming.which has continued ever since.

The input is all the papers I've read over 43 years. There' s no chance that I can supply a complete bibliography!

The output is my own mental model of the climate, with inputs from physics, chemistry, biology, meteorology, astronomy, oceanography and whatever else came in handy.
This list should really be a spider diagram, but since that only exists in my head, I can't show all the interconnections here.

I don't know how much of this is in the literature. Some are obviously documented, others less so. I don't recall anyone discussing trends in downwelling radiation, but they are only just started monitoring it.

The list is very much a personal document, made up for fun and as an aide memoire. I don't insist that it is perfect, complete, or even correct, but I hope it gives food for thought.

Enjoy.

EM - thanks for posting your list. I echo throg's request for the details.

Interesting EM.

You have a mixture of factors, some of which are simply the effects of a gentle warming over 250 years, others potentially indicators of effects of anthropogenic CO2, some are debatable (I will leave those to the physicists here) and others are clearly negative feedbacks. Some (such as O2 depletion, sea acidification and sea level rise) are clearly de minimis, regardless of what the IPCC and Manbearpig might say. There are a couple (Antarctic sea ice and Antarctic temperatures) that argue directly against you. The "extreme weather" part is quite simply wrong, as numerous studies show.

The only potentially scary thing here is your last section about methane, so I would want to see your evidence. Apart from that, all your list adds up to is a modest amplification of a pre-existing warming trend, offset by some negative feedbacks, leading to an overall trend of perhaps .05ºC -.07ºC per decade and improved growing conditions across much of the globe.

Interesting how what we think of as news is simply a re-hash.

Hi Entropic Man

John Brignell @ Numberwatch has spent many years compiling a list of things linked to Global Warming. Enjoy.

Hence my morbid interest in Entropic Man's links. Particularly after his "rapidly accelerating sea level rise" of a few months perhaps longer ago which then reverted back to normal. Although I had previously wasted time on another bulk list which turned out not to be exactly as claimed.

O2 decrease is not necessarily complementary to CO2 increase. Think for example of anaerobic desperation. However, since most of the anthropogenic increase in CO2 is by combustion of fossil fuels or oxidation of limestone for cement, so its a good approximation.
I thought it worth including both metrics ( good term, throg )as cross- validation. It is always worth measuring in as many different ways as possible, to minimise the effect of problems with individual techniques.

We are a civilisation of coastal plains and, as I have recently been reminded, river valleys. The last six weeks have demonstrated how easily big chunks of our infrastructure can be disrupted. I expect climate change to bring even larger disruption, perhaps beyond our capacity to adapt. Many previous civilisations have been disrupted that way. I see no special reason why we are exempt.

This came out of a lifetime's reading, without keeping a list of references.

Any references I put up would be from Internet sources. You can use the list as a starting point for Google or Google Scholar searches just as well as I, with the added confidence that you are dodging any spin I might apply.

I've no great desire to turn this into a game of reference tennis.

You left out skirt lengths.

You only need one GW reference: JASO Atlantic, 1M to 30N. Format any years figures against 30 years pree 1900 (HadiSST1 or whatever). This will demonstrate a pronounced and specific area of the E Atlantic that demonstrates every criteria necessary for GW. An even better refinement of this data is subtracting the SST of water flowing south into this zone from the water in the zone. This provides an indicator of how much additional solar SW is being absorbed each year. The result should reveal an almost straight line comfortably above the mean since 1970 with no significant reduction during the haiatus period. Don't just chat about climate science, crunch the number yourself.

Is this your presentation?
