Planning meetings for the Global Seed Vault in Norway spawned the idea of looking at average summer temperatures, which climate models can project relatively reliably and which have a large impact on crop yields — between 2.5 and 16 percent less wheat, corn, soy or other crops are produced for every 1.8 — degree F (1 — degree C) rise.

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.

If we can rein in emissions enough to keep global average temperatures from rising 2 C (3.6 F), we can avert the biggest shocks to Earth's system, scientists say.

But even with such policies in place — not only in the U.S. but across the globe — climate change is a foregone conclusion; global average temperatures have already risen by at least 1.1 degrees Fahrenheit (0.6 degree C) and further warming of at least 0.7 degree F (0.4 degree C) is virtually certain, according to the IPCC.

The real forecast is 383 ppm rising at 2 ppm / year, a minimum carbon dioxide sensitivity to doubling of 3 C, adding positive feedbacks, some of which are unknown, yields a 5 C increase in global average temperatures by 2100, and of course, time does not stop in 2100.

The Paris agreement, at minimum, aims to keep the rise in average global temperatures «well below» 2 degrees C compared to pre-industrial levels.

Just last week, preliminary research at the Leibniz Institute of Marine Sciences in Kiel, Germany, suggested that natural variations in sea temperatures will cancel out the decade's 0.3 C global average rise predicted by the IPCC, before emissions start to warm the Earth again after 2015.

Though a 1 C rise in global temperature may not tell us anything about global climate - temperature is not really something which effect humans or life, whereas patterns rainfall, would be more relevant than average global temperature.

In order to achieve the target set by the Paris Agreement --- to limit the rise in global average temperature to below the 2 degree C threshold — all new construction must be designed to high energy efficiency standards and use no CO2 - emitting fossil fuel energy to operate; by 2050 the entire built environment must be carbon neutraIn order to achieve the target set by the Paris Agreement --- to limit the rise in global average temperature to below the 2 degree C threshold — all new construction must be designed to high energy efficiency standards and use no CO2 - emitting fossil fuel energy to operate; by 2050 the entire built environment must be carbon neutrain global average temperature to below the 2 degree C threshold — all new construction must be designed to high energy efficiency standards and use no CO2 - emitting fossil fuel energy to operate; by 2050 the entire built environment must be carbon neutral.

The crucial framework of limiting the average global temperature rise to below 2 ° C (from pre-industrial levels) will be developed at the 2015 United Nations Climate Change Conference in Paris.

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

Last month's jump in global temperatures represents an increase of 1.35 C above the average temperature level for the period 1951 - 80 and 1.63 C above pre-industrial levels, taking global temperature for the month above the 1.5 C rise that last year's Paris climate was supposed to prevent.

Observed changes in (a) global average surface temperature; (b) global average sea level rise from tide gauge (blue) and satellite (red) data and (c) Northern Hemisphere snow cover for March - April.

Further, we have no plan to reduce dependency on fossil fuels, even as we sign on to global statements about the need to keep greenhouse gases from rising above 450 ppm in the atmosphere to keep global average temperatures from exceeding a growth of 2 degrees C.

The thawing of permafrost in the region has been linked to global warming.5 Annual average air temperatures rose 1.1 ° F (0.6 ° C) from 1960 to 2005,6,11,12 while permafrost at a depth of 33 feet (10 meters) warmed an average of 0.5 ° -1.3 ° F (0.3 ° -0.7 ° C).6, 12

Tack on, without the large and growing number of self - reinforcing feedback loops we've triggered recently, the 5 C rise in global - average temperature 55 million years ago during a span of 13 years, and it looks like trouble ahead for the wise ape.»

Even if we succeed in holding global temperature rise to 2C or 1.5 C above pre-industrial levels, both average and extreme temperatures in some regions could still climb way beyond these limits, the researchers say.
