Also, Scandinavian lakes had been
affected by natural variability and by altered run - off from land resulting from changed forestry practices.
As a result, surface temperature is strongly
affected by natural variability.
Air temperatures are
affected by natural variability.
Isn't 50 years a short enough time span, historically speaking, to be
affected by natural variability?
Not exact matches
Ultimately, in forests not otherwise limited
by energy or nutrients
variability in moisture availability with
natural and climate oscillations may drive establishment success between years (League and Veblen 2006), with indirect disturbance effects (e.g., fires, landslides, insect outbreaks, and pathogen attacks) greatly
affecting long - term recruitment success (Clark et al. 2016).
In addition, both internal
variability and aerosol forcing are likely to
affect tropical storms in large part though changes in ocean temperature gradients (thereby changing ITCZ position and vertical shear), while greenhouse gases likely exert their influence
by more uniformly changing ocean and tropospheric temperatures, so the physics of the problem may suggest this decomposition as more
natural as well.
Weapon testing
by the USSR in the Arctic during October 1961 resulted in heavy snowfalls in the UK in the winter of 1962/3 but it is difficult to draw conclusions since
natural variability, the solar cycle and El & La Nini can also
affect the global and local temperatures.
Many households were deeply
affected by climatic
variability and
natural disasters coupled with a decade - long conflict, leaving them with few options to cope with CC in Nepal.
In addition to regional climate change being strongly
affected by natural modes of
variability, geographic differences in climate change are related to the uneven spatial distribution of aerosols and tropospheric ozone.
How does
natural and internal
variability affect the apparent rate of storage as measured
by the current proxy for storage of sensible heat in the troposphere?
that's the point, pogac is not just
natural variability, sst in the enso regions are
affected by radiative forcing too.
Consequently, many
natural and managed systems are being
affected by both climate change and climate
variability.
We can at best estimate that
natural variability is an order of magnitude or two smaller than the GHE for climate timescales, which is good enough, since our precision on temperatures on climate timescales barely has enough significant digits to be
affected by a two order of magnitude lower effect.
Thus, future climate trends in regions
affected by the NAO are best conveyed in terms of an expected range that incorporates both the
natural variability and the forced climate change signal.
Changes in climate at the local to regional scale can be influenced
by natural variability for multiple decades.28 This can
affect the interpretation of climate trends observed regionally across the U.S. (see Appendix 3: Climate Science Supplement).
Until the rest of
natural climate
variability is understood and incorporated into the process of understanding how the weather works, and the climate is
affected by the rest of the solar system, and its interactions with the rest of the galaxy, the background senseless chatter will fall on deaf ears.
Especially important is to note that all four are
affected by the same, single instance of
natural variability of the real Earth, which for the last decade or so seems to be trending down, against the forced trend.
The big question now becomes how much is anthropogenic forcing
affecting the
natural internal
variability that formerly (prior to the mid-20th century) was driven
by solar
variability and ocean cycles.
I am not sure I am seeing the distinction here between the two definitions, unless you are saying that «internal»
natural variability (oceans / Atmosphere) can be
affected by man's activities, in which case its a bit of a misnomer to call it
natural.
There are also other
natural «modes of
variability» which may be
affected by a climate change, for instance if the heat transport in the oceans are to change (e.g. the Atlantic meridional overturning circulation AMOC).
The
natural variability may be further reduced
by averaging over more realisations, over longer time intervals, and
by averaging in space, although averaging also
affects the information content of the result.
[2] However, there is an extremely wide range of
natural variability in tropical cyclone activity, and other factors
affected by climate change, such as wind shear and the global pattern of regional sea surface temperatures, also play controlling and potentially contradictory roles.
