In warm periods such as the present — freshwater inflow to
high northern latitudes reduces the rate of water sinking to the depths of the ocean.
Not exact matches
These large
Northern Hemisphere cooling events have previously been linked to a change in the Atlantic Ocean circulation that led to a
reduced transport of warm water to the
high latitudes in the North.
This WP aims to improve the resolution of ocean models, as well as the representation of physical and biogeochemical processes, in key regions of the world's oceans (particularly tropical coastal regions, the Southern Ocean and
high Northern latitudes) to
reduce well known biases in ESMs.
Near - surface permafrost at
high northern latitudes will be
reduced as the global mean surface temperature increases.
Reduced sensitivity of recent tree growth to temperature at
high northern latitudes.
In this article I present prima facie evidence that the ongoing natural increase in spring insolation occurring at
high northern latitudes, coupled with the positive feedback effect of the resultant snow and ice loss
reducing the region's mean albedo over summer, comprises just such a causative agency.
In the case of the 100 kyr ice age cycles, that forcing is
high northern latitude summer insolation driven by predictable changes in Earth's orbital and rotational parameters — aka, Milankovitch theory — which has the intial effect of melting glaciers, thereby
reducing albedo at those
latitudes.
The main reason for this warmer climate was an increased amount of energy from the Sun being received at
high northern latitudes due to Earth's orbital configuration, plus Earth had an increased capacity to absorb heat due to vegetation changes and
reduced ice and snow cover.
Reduced sensitivity of recent tree - growth to temperature at
high northern latitudes.
Such changes are observed in many places, especially over land in middle and
high latitudes of the
Northern Hemisphere, leading to increased rains but
reduced snowpacks, and consequently diminished water resources in summer, when they are most needed.
