Tip # 2: You will need to store the tahini in a BPA - free air - tight container in the refrigerator, and it may become hard (due to the coconut oil), but just leave it out on your counter top at room temperature before using, or put it in a bowl of warm water to soften it up.
First, sea - surface temperatures in the Gulf of Mexico have been higher than normal in the past couple of months, due to global warming, which means the air that flowed north would have been warmer to start with.
The more intensive variations during glacial periods are due to the greater difference in temperature between the ice - covered polar regions and the Tropics, which produced a more dynamic exchange of warm and cold air masses.
The Michigan Tech chamber works differently due to cloud mixing between a hot and cold surface, the same process that forms clouds or fog over a lake on fall days when the water temperature is warmer than the air temperature.

Now I've seen mentions that (strong) El Nino years will make the global annual average higher — e.g. 1998 was so warm partly because of El Nino, and that this is due to the fact that sub-surface warmer water is brought up and allowed to affect the air temperature.
Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.
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).

While tropical hurricane intensity is primarily driven by latent heat from warm sea surface temperatures, an extra-tropical storm is primarily driven by baroclinic processes (differences in the pressure gradient) such as the gradient due to the contrast between the warm Gulf Stream and cold continental air mass.
This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18
«Thus, rising air is said to cool or warm adiabatically when its temperature changes are due entirely to pressure changes.
This is due to a phenomenon called the urban heat island effect that causes air temperatures in New York City and other major cities to be warmer than in neighboring suburbs and rural areas.
To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).
(Any higher and they start to suffer stratospheric heating due to the vertical temperature profile reversing at the tropopause — the lapse rate changes sign and the air gets warmer instead of colder with altitude.)
so, yeah, it is really convenient that ocean surface temperatures have gone down since the 1998 el nino due to wind patterns but that extra heat going into the ocean is just as much a component of warming as air temperatures.
Warm water on Mars, boils - it's lacks atmospheric pressure lowers the boiling point to somewhere around 5 to 10 C. And 5 C water would not boil on Mars, but it would evaporate quicker on Mars then it does on Earth - because no where on Earth is drier than Mars [due to changing temperatures, frost does form on the Mars surface at equator and at nite - this requires the thin Mars air to become saturated - but generally very dry.
Significant surface melting due to warm air temperatures created melt ponds that acted like wedges; they deepened the crevasses and eventually caused the shelf to splinter.
All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.
Lansner and Pepke Pedersen (2018) point out that, due to the divergent rates of warming and cooling for land vs. ocean water, there is a significant difference in the range of temperature for the regions of the world influenced by their close proximity to oceans and coastal wind currents (ocean air affected, or OAA) and the inland regions of the world that are unaffected by ocean air effects and coastal wind because they are sheltered by hills and mountains or located in valleys (ocean air sheltered, or OAS).
Temperatures often fluctuate in the Arctic due to the strength or weakness of the polar vortex, the circle of winds — including the jetstream — that help to deflect warmer air masses and keep the region cool.
The air circulation systems in both hemispheres move back equatorward and the ITCZ moves nearer the equator as the speed of the hydrological cycle decreases due to the warming stratosphere reducing the temperature differential between stratosphere and surface.
Natural variability in air temperature (the lack of significant warming in the last decade) can be regarded as noise in the monotonic increase due to GHGs, but a one year total (ocean) heat content change can't.
It is still called global warming, a good description of the general shift in average global temperatures due to the greenhouse warning effect of the addition of 35 billion tons of CO2 into the air each year from burning fossil fuels.
For the change in annual mean surface air temperature in the various cases, the model experiments show the familiar pattern documented in the SAR with a maximum warming in the high latitudes of the Northern Hemisphere and a minimum in the Southern Ocean (due to ocean heat uptake) evident in the zonal mean for the CMIP2 models (Figure 9.8) and the geographical patterns for all categories of models (Figure 9.10).
