seasonal release of CO2 and CH4 as a result of only a mild
temperature increase, and dug deeply into the reason behind the observed
changes by detailed soil and vegetation measurements.
Cracking driven
by daily and
seasonal temperature changes may help explain substantial fraction of sunny - day rockfalls
Climate
change, resulting in more frost - free days and warmer
seasonal air
temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2
by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23

temperature changes caused
by the summer Monsoon and rich marine food supplies (Sardines & Euphasids) enables both breeding and feeding within the same body of water.
While the local,
seasonal climate forcing
by the Milankovitch cycles is large (of the order 30 W / m2), the net forcing provided
by Milankovitch is close to zero in the global mean, requiring other radiative terms (like albedo or greenhouse gas anomalies) to force global - mean
temperature change.
Although the primary driver of glacial — interglacial cycles lies in the
seasonal and latitudinal distribution of incoming solar energy driven
by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial
temperature and ice volume
changes can not be explained without accounting for
changes in atmospheric CO2 content and the associated climate feedbacks.
The lapse rate within the troposphere is largely determined
by convection, which redistributes any
changes in radiative heating or cooling within the troposphere + surface so that all levels tend to shift
temperature similarly (with some regional / latitudinal, diurnal, and
seasonal exceptions, and some exceptions for various transient weather events).
Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted
by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional
changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much
temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the
seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
If the planetary
temperatures rise beyond the 1.5 °C to 2 °C limit proposed
by the Paris agreement signed
by 197 nations in 2015, then climate
change could arrive in Mali, Niger and Chad in the shape of intense rains of the kind identified as
seasonal monsoons.
The three different ozone databases yield
changes in tropical lower stratospheric
temperatures that differ
by more than a factor of two at 70 mbar, although all have qualitatively similar
seasonal cycles.
Have a look at the
seasonal changes at Mauna Loa: The influence of
temperature is clear: warmer in this case means more CO2 eaten away
by vegetation and reverse when
temperatures in the NH drop.
Climate
change, resulting in more frost - free days and warmer
seasonal air
temperatures, can contribute to shifts in flowering time and pollen initiation from allergenic plant species, and increased CO2
by itself can elevate production of plant - based allergens.137, 15,16,17,18,19,138 Higher pollen concentrations and longer pollen seasons can increase allergic sensitizations and asthma episodes, 20,21,155,22 and diminish productive work and school days.138, 22,23
I have sought the best empirical evidence to show how
changes in incoming solar radiation, accounted for
by intrinsic solar magnetic modulation of the irradiance output as well as planetary modulation of the
seasonal distribution of sunlight, affects the thermal properties of land and sea, including
temperatures.
Third, the ice core data how conclusively that, during natural climate cycling,
changes in
temperature precede
changes in carbon dioxide
by an average 800 years or so (Fischer et al, 1999; Indermuhle et al, 2000; Mudelsee, 2001; Caillon et al, 2003); similarly,
temperature change precedes carbon dioxide
change, in this case
by five months, during annual
seasonal cycling (Kuo, Lindberg and Thomson, 1990).
Gregory and Oerlemans (1998) applied local
seasonal temperature changes over 1860 to 1990 calculated
by the HadCM2 AOGCM forced
by changing greenhouse gases and aerosols (HadCM2 GS in Table 9.1) to the glacier model of Zuo and Oerlemans.
The initial
changes in
temperature during this period are explained
by changes in the Earth's orbit around the sun, which affects the amount of
seasonal sunlight reaching the Earth's surface.
«There is evidence of an emerging pattern of climate response to forcing
by greenhouse gases and sulfate aerosols... from the geographical,
seasonal and vertical patterns of
temperature change... These results point toward a human influence on global climate.»
Due to the much higher heat capacity of soil relative to air and the thermal insulation provided
by vegetation and surface soil layers,
seasonal changes in soil
temperature deep in the ground are much less than and lag significantly behind
seasonal changes in overlying air
temperature.
In order to determine the optimal depth of burial, it is important to accurately know how the
seasonal change in soil
temperature varies with depth, which is mainly determined
by the soil's thermal properties.
These unique fingerprints are easier to see
by probing beyond a single number (such as the average
temperature of Earth's surface), and looking instead at the geographical and
seasonal patterns of climate
change.
The researchers found the birds appear to be «well equipped» to cope with
seasonal temperature changes brought about
by climate
change.
Scientists also factored long - term, climate

by looking at the last 10 to 15 years of
temperature and precipitation across the country.
Changes in CO2 emissions from fossil fuel combustion are influenced
by many long - term and short - term factors, including population growth, economic growth,
changing energy prices, new technologies,
changing behavior, and
seasonal temperatures.
Pre-TAR AOGCM results held at the DDC were included in a model intercomparison across the four SRES emissions scenarios (B1, B2, A2, and A1FI) of
seasonal mean
temperature and precipitation
change for thirty - two world regions (Ruosteenoja et al., 2003).9 The inter-model range of
changes by the end of the 21st century is summarised in Figure 2.6 for the A2 scenario, expressed as rates of
