Sentences with phrase «on average the temperature of the earth»

I am still waiting for word on what the global temperature anomaly for the month was, but I suspect it will be fairly close to normal, which means that on average the temperature of the Earth will come in at ~ 12.0 °C which is 4 °C colder than it will be in 6 months from now, but because of how they talk about temperature, I will be the only one pointing out the difference between the actual temperature and the anomaly temperature.

But here's your question: why we should be concerned even with the global temperature rise that has been predicted, let's say by 2050, of probably around 2 degrees C; one should understand that in the Ice Age — the depths of the Ice Age — the Earth was colder on a global average by about 5 degrees C.

As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

Global average temperature is lower during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth surface was more reflective, due to the presence of lots of ice and snow on land, and lots more sea ice than today (that is, the albedo was higher).
But even when carbon dioxide does make its way out of the atmosphere, Earth's natural systems can release other carbon dioxide molecules that were previously stored in the oceans / land back into the atmosphere, making the full effect of carbon dioxide emissions on surface temperatures much longer than this 5 - 200 year average.

One study estimates that there are likely to be places on Earth where unprotected humans without cooling mechanisms, such as air conditioning, would die in less than six hours if global average surface temperature rises by about 12.6 ° F (7 ° C).16 With warming of 19.8 - 21.6 ° F (11 - 12 ° C), this same study projects that regions where approximately half of the world's people now live could become intolerable.7
We see a greenhouse effect (higher surface temperature) at the Earth's surface because the temperature of the gas (atmosphere) on average is less than the temperature of the source (surface).
However, over long time periods, the variation of the global average temperature with CO2 concentration depends on various factors such as the placement of the continents on Earth, the functionality of ocean currents, the past history of the climate, the orientation of the Earth's orbit relative to the Sun, the luminosity of the Sun, the presence of aerosols in the atmosphere, volcanic action, land clearing, biological evolution, etc..

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.
The fact is, we are the ones on this planet with the highest energy consumption and the end result of all this energy consumption is a steady increase of heat, carbon dioxide and other by - products into the atmosphere produced by us that is causing gradual increases in the average temperature of the earth's atmosphere from year to year.
