The observed
patterns of
warming, including greater
warming over
land than over the ocean, and their changes over time, are only simulated by models that include anthropogenic forcing.
My point, which I hope you would likewise concede, is that even with a weakened or shut - off THC, western Europe would still remain
warm relative to other
land masses at the same latitudes (possibly even
warmer than British Columbia, as it is now), based primarily on atmospheric circulation
patterns.
Does the
pattern of change (
warming raises the equilibrium temperature, cooling decreases it), indicate a negative feedback on sea level change (e.g. as
land ice melts it requires a little
warmer temperature to continue to melt further
land ice... and vice versa??).
It isn't an isolated conclusion from a single study, but comes from an assessment of the changing
patterns of surface and tropospheric
warming, stratospheric cooling, ocean heat content changes,
land - ocean contrasts, etc. that collectively demonstrate that there are detectable changes occurring which we can attempt to attribute to one or more physical causes.
And given the fact that
land warms more quickly than ocean, resulting in areas of low pressure over
land, changing
patterns of atmospheric and oceanic circulation are bringing them to the coasts — where so much life's diversity is found.
It is almost certain that the strange extreme weather
patterns now observed throughout the northern hemisphere are related to this arctic
warming and the consequent weakening of the jet streams that lie between the arctic and the more temperate northern
lands.
In terms of the gold that a climate science denier might find in the paper, at the very least, they could argue that the fact that the troposphere isn't
warming more quickly than the surface shows that the climate models are unreliable — even though the models predict just the
pattern of
warming that we see — with the troposphere
warming more quickly than the surface over the ocean but less quickly than the surface over
land.
Warming over
land can have multiple effects, including melting of mountain glaciers, spread of deserts in continental interiors, greater flooding, more frequent heat waves and other extreme weather
patterns.
One of the problems is that if the
land is
warming faster and to a greater extent than the atmosphere, then the
warming pattern is not consistent with the GHE and there must be some other explanation for the
land warming.
• carbon is captured • water is captured • habitat for methane metabolizing bacteria is established • localized cooling is enhanced • localized
warming is diminished •
land is more drought resistant • localized weather
patterns are favorably impacted
That means that looking at SST should be sufficient to follow any
warming patterns and avoids introducing the
land / sea ratio bias of NH.
To help stop deforestation — and to reduce the heat - trapping emissions that cause global
warming — we need to make smart decisions that shift consumption and
land use
patterns in less wasteful directions.
Greenland's ice has been melting faster than many scientists expected just a decade ago, spurred by
warming sea and
land temperatures, changing weather
patterns, and other factors.
Averaged over the five - year period 2016 - 2020, forecast
patterns suggest enhanced
warming over
land, and at high northern latitudes.
Even if we stopped emitting greenhouse gases today, fire conditions will become even more persistent in areas already at risk, and will spread to new regions as
warming drives vegetation
patterns and
land - use changes.
The anomalously
warm and cold periods are probably caused by the variation of volcanic & solar activities,
land use changes and perhaps the change of oceanic circulation
pattern, but the contribution of each component is not well understood.
The climate models have gotten more complex, for sure, with thousands of estimated parameters for
warming potential, vorticity, circulation
patterns, absorption of heat, pressure, energy, and momentum by various layers or atmosphere,
land, ocean, and sea - ice.
Looking at their Table 3, only 2 out of 22 CMIP3 climate models have significant explanatory power for the spatial
pattern of
warming trends over
land, and the rest have no significant explanatory power or are even anticorrelated with the observed trends.

And we showed that the contamination
patterns account for about half the surface
warming measured over
land since 1980.
There were very few readings from the Arctic, yet the Arctic is by far the fastest -
warming region of the planet, and the
pattern of
land - based temperature readings, too, repaid re-examination.
The observed
patterns of surface
warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of
land and sea ice also match the
patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).
Dubbed the «blue pearl» for its pristine state, Lake Hovsgol, besieged on two fronts by harmful
land - use
patterns and the effects of global
warming, risks tipping into an «alternative stable state»:
Further affirmation of the reality of the
warming is its spatial distribution, which has largest values at locations remote from any local human influence, with a global
pattern consistent with that expected for response to global climate forcings (larger in the Northern Hemisphere than the Southern Hemisphere, larger at high latitudes than low latitudes, larger over
land than over ocean).
Secondly, are you insane??? Tropical diseases will have a wider band around the earth with
warming, bug infestations that destroy plants and trees are already having a field day, weeds are likely to overwhelm agricultural
lands since they respond much better to increased co2 than do cultivated plants, weather
patterns will change and everything dependent on weather will have to adjust etc. etc..
The
pattern of future
warming where
land warms more than the adjacent oceans and more in northern high latitudes is seen in all scenarios.
