Sentences with phrase «by seasonal temperature changes»

Not exact matches

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.

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 change per century.
