However, even just 1 degree warming was huge
in high latitude areas where polar amplification is occurring (early Jan 2006 post at RC).
After doing all that, and in actually seeing the high latitude warming amplification, the only kind of global warming that could be happening is greenhouse gas driven, in order to explain the amplified warm overnight low temperature observations shown in the data as occurring
in higher latitude areas... where low humidity air is transitioning into air with higher humidity levels (H2O GHG).
Second, Steve consistently appears in the presence of auroras, which usually occur at
a higher latitude area called the auroral zone.
The faster increases in AP are more significant in low latitude areas (tropical and sub-tropical regions) than the middle and
high latitude areas.
«Whales feed in highly productive and
high latitude areas and then they migrate to low productivity, low latitude areas.
So what you really want is a good canary in the coal mine and
the high latitude areas are canaries, whereas the global average hides real stress.
We talk about temperatures in
high latitude areas, like the Arctic, because, as a general rule, high latitude areas are much more sensitive to human stress than the global average.
High latitude areas are tending to see more significant increases in rainfall, while precipitation has actually declined in many tropical areas.»
This report summarizes current knowledge on potential abrupt changes to the ocean, atmosphere, ecosystems, and
high latitude areas, and calls for action to help anticipate future abrupt changes and reduce their impacts.
The new study, coupled with NASA's previous findings, confirms that Arctic greening is indeed an alarming trend and global warming has been greatly affecting the vegetation in
high latitude areas.
