"Planetary temperature" refers to the average temperature of a planet, like Earth or Mars, which indicates how hot or cold the planet is overall.
Full definition
Once the appropriate
planetary temperature increase has been set by the delay in transmission through the atmosphere then equilibrium is restored between radiant energy in and radiant energy out.
During 2014, as rising ocean heat fueled
planetary temperature records, and as it continued to eat away at Antarctic ice, scientists discovered that the oceans have been warming far more quickly than anybody had realized — and doing so for decades.
Holmes points out that the implications of his precise calculations
for planetary temperatures necessarily lead to the conclusion that there is no need to have a greenhouse effect or greenhouse gases to bridge a hypothetical «heat gap.»
Then they settled down to calculate the likelihood that a proportion of past heatwaves or floods could be linked to a measured average rise in
planetary temperatures so far of 0.85 °C.
Second, ignore the inconsistencies, and just assume those pesky CO2 molecules are so clever that they can change the trajectory of
planetary temperature trends every few decades, from warming to cooling, back to warming, then just «flatline» for fifteen years or so.

Planetary Temperature Model.
To be in the star's habitable zone, any suspected planet around Alpha Centauri A would have to be optimally placed about 1.25 AU away [citation needed]-- about halfway between the distances of Earth's orbit and Mars's orbit in the Solar System — so as to have
similar planetary temperatures and conditions for liquid water to exist.
This is basic research at a down - to - earth level: climate science can't make sense of what is happening now without a better understanding of what has always happened, and of the swings in
planetary temperatures over the past 4.5 billion years.
Because Al Gore switched his CO2 and temperature curves to make it look like rising carbon dioxide levels
caused planetary temperature increases — when in fact increasing temperatures always preceded higher CO2 — shouldn't he have corrected his mistake, returned his ill - gotten millions, and shared his 2007 Nobel Prize and money with Irena Sendler, who should have gotten it for saving 2,500 Jewish children during World War II?
«It is no surprise that their predictions of
planetary temperature made in 1988 to the U.S. Congress, and again in 1990, 1995, and 2001, have all proved much higher than reality.»
A rising
planetary temperature sets in motion all sorts of secondary effects that can boost the temperature even higher — effects like melting Arctic sea ice, rising levels of heat - trapping water vapor in the atmosphere, and... Read More
Plants built their tissues from atmospheric carbon, animals devoured plants and released most of the carbon again as a greenhouse gas, and
planetary temperatures hovered around a long - term average.
They worked out how these proportions would change if the average
planetary temperatures reach 2 °C above the «normal» of the pre-industrial world, and they found that human - induced global warming could already be responsible for 18 % of extremes of rain or snow, and 75 % of heatwaves worldwide.
Planets with atmospheres stabilise their surface temperatures at a level dependent upon the density of the atmosphere leaving the main variation in
planetary temperature dependent on variations in the energy coming in from the local star.
