Taking account of their historic responsibility, as well as the need to secure climate justice for the world's poorest and most vulnerable communities, developed countries must commit to legally binding and ambitious emission reduction targets consistent with limiting global average surface warming to well below 1.5 degrees Celsius above preindustrial levels and long - term stabilization of atmospheric greenhouse gas concentrations at well below below 350 p.p.m., and that to achieve this the agreement at COP15 U.N.F.C.C.C. should include a goal of peaking global emissions by 2015 with a sharp decline thereafter towards a global reduction of 85 percent by 2050,

Governments worldwide have in principle accepted that greenhouse gas emissions should be reduced and average global warming limited to a rise of 2 °C.

bozzza - The differences in the Arctic are perhaps 1/4 the ocean thermal mass as global ocean averages, small overall size (the smallest ocean), being almost surrounded by land (which warms faster), more limited liquid interchanges due to bottlenecking than the Antarctic, and very importantly considerable susceptibility to positive albedo feedbacks; as less summer ice is present given current trends, solar energy absorbed by the Arctic ocean goes up very rapidly.

So if our goal is to limit warming to 1.5 degrees there will be an «overshoot», taking warming to at least 2 and perhaps 3 degrees, before the average global temperature can be brought back down.

The Paris Agreement's long - term goal is to limit global warming to 1.5 to 2.0 degrees Celsius (2.7 to 3.6 degrees Fahrenheit) above preindustrial temperatures, or about 0.5 to 1.0 degrees C (0.9 to 1.8 degrees F) above the current global average temperature.

b. All nations agreed to limit the increase in global average temperatures to «well below 2 °C above pre-industrial levels» — the level beyond which scientists believe the Earth will likely begin to experience rapid global warming and to «pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels», a warming amount which may also cause serious global harms particularly to many poor, vulnerable nations.

Based on current knowledge, however, it appears that achieving a high probability of limiting global average temperature rise to 2C will require that the increase in greenhouse - gas concentrations as well as all the other warming and cooling influences on global climate in the year 2100, as compared with 1750, should add up to a net warming no greater than what would be associated with a CO2 concentration of about 400 parts per million (ppm).

While the richest income class in this study, earning more than 30,000 rupees a month, produce slightly less than the global average CO2 emissions of 5 tonnes, this amount already exceeds the sustainable global average CO2 emissions of 2.5 tonnes per capita that needs to be reached to limit global warming below 2 degrees centigrade.

This is the total amount of CO2 emissions that we can still emit whilst limiting global average warming to 1.5 C.

Last year was the hottest since records began and with an El Nino now under way the warm surface waters of the Pacific are releasing heat into the atmosphere with the result 2015 is likely to break last year's record and the global average surface temperature could jump by as much as 0.1 degree this year alone bring global surface temperatures increases to 1 degrees or half way to the UN global limit.

Molden said that based on recent research, limiting average global temperatures at a 2 degree Celsius rise from pre-industrial levels — as envisaged by the historic Paris accord of 2015 — in the world means 3 to 4 degrees of warming in the mountains, while limiting average global temperature rise to 1.5 degree Celsius would mean a 3 degree Celsius rise in high - altitude areas.

While many scientists and climate change activists hailed December's Paris agreement as a historic step forward for international efforts to limit global warming, the landmark accord rests on a highly dubious assumption: to achieve the goal of limiting the rise in global average temperature to less than 2 °C (much less the more ambitious goal of 1.5 °C), we don't just need to reduce emissions of carbon dioxide to essentially zero by the end of this century.
