Generally, the remaining uncorrected effect from urban heat islands is now believed to be less than 0.1 C, and in some parts of the world it may be more than fully compensated for by other changes in measurement methods.4 Nevertheless, this remains an important source of uncertainty.The warming trend observed over the past century is too large to be easily dismissed as a consequence of measurement errors.

The uncertainty is whether this, when applied to the real world, is a trivial effect (say the lowest outlier position), if there is a couple of degrees warming coming (an average position, where warming will have some observable effects within a decade or two) or 5 + deg C (the highest outlier position, where significant and rapid change would occur, and where detrimental effects probably significantly outweigh beneficial ones).

Even if «catastrophic» AGW is correct and we do warm another 3 C over the next century, if it stabilized the Earth in warm phase and prevented or delayed the Earth's transition into cold phase it would be worth it because the cold phase transition would kill billions of people, quite rapidly, as crops failed throughout the temperate breadbasket of the world.

In summary, a strong case can be made that the US emissions reduction commitment for 2025 of 26 % to 28 % clearly fails to pass minimum ethical scrutiny when one considers: (a) the 2007 IPCC report on which the US likely relied upon to establish a 80 % reduction target by 2050 also called for 25 % to 40 % reduction by developed countries by 2020, and (b) although reasonable people may disagree with what «equity» means under the UNFCCC, the US commitments can't be reconciled with any reasonable interpretation of what «equity» requires, (c) the United States has expressly acknowledged that its commitments are based upon what can be achieved under existing US law not on what is required of it as a mater of justice, (d) it is clear that more ambitious US commitments have been blocked by arguments that alleged unacceptable costs to the US economy, arguments which have ignored US responsibilities to those most vulnerable to climate change, and (e) it is virtually certain that the US commitments can not be construed to be a fair allocation of the remaining carbon budget that is available for the entire world to limit warming to 2 °C.

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

Should a developed nation such as the United States which has much higher historical and per capita emissions than other nations be able to justify its refusal to reduce its ghg emissions to its fair share of safe global emissions on the basis of scientific uncertainty, given that if the mainstream science is correct, the world is rapidly running out of time to prevent warming above 2 degrees C, a temperature limit which if exceeded may cause rapid, non-linear climate change.

Every year, the UN Environment Programme (UNEP) brings together scientists from around the world to measure the size of the greenhouse gas (GHG) «emissions gap,» the difference between the emissions level countries have pledged to achieve under international agreements and the level consistent with limiting warming to well below 2 degrees C (3.6 degrees F).
