«Considering the Southern Ocean absorbs something like 60 % of heat and anthropogenic CO2 that enters the ocean, this wind has a noticeable effect on global warming,» said lead author Dr Andy Hogg from the Australian National University Hub of the ARC Centre of Excellence for Climate System Science.

This is an attitude that some sincere climate change «skeptics» (as opposed to ExxonMobil - funded deliberate frauds) exhibit: their so - called «skepticism» arises from an a priori sense that human activities can not possibly affect the Earth system in the way that the theory of anthropogenic global warming describes.

Quoting directly Climate change as a result of human activities, or anthropogenic global warming, is now generally accepted as reality and includes a wide range of climatic processes and impacts in the global system that are affected by human activities.

Anthropogenic Warming of Earth's Climate System in Science 2001 292: 267 - 270.

Anthropogenic climate change will mean an increased average temperature for the oceans and possible changes in current systems that could locally amplify or reduce warming and can alter nutrient cycling resulting in changes in the amount of nutrients available for the growth of phytoplankton, the plant plankton that are the base of the food chain.

(3) From the supporting perspective article: «All this would be very bad news if avoiding dangerous anthropogenic interference in the climate system required us to specify today a stabilization concentration of carbon dioxide (or equivalent) for which the risk of dangerous warming is acceptably low.

Recognizes that warming of the climate system is unequivocal and that most of the observed increase in global average temperatures since the mid twentieth century is very likely due to the increase in anthropogenic greenhouse gas concentrations, as assessed by the Intergovernmental Panel for Climate Change in its Fourth Assessment climate system is unequivocal and that most of the observed increase in global average temperatures since the mid twentieth century is very likely due to the increase in anthropogenic greenhouse gas concentrations, as assessed by the Intergovernmental Panel for Climate Change in its Fourth Assessment Climate Change in its Fourth Assessment Report;

... we strongly support Delworth and Knutson's (2000) contention that this high - latitude warming event represents primarily natural variability within the climate system, rather than being caused primarily by external forcings, whether solar forcing alone (Thejll and Lassen, 2000) or a combination of increasing solar irradiance, increasing anthropogenic trace gases, and decreasing volcanic aerosols.

The IPCC concluded that «the effects [of greenhouse gases], together with those of other anthropogenic drivers, have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century.»

So you answer that «the climate system is profoundly complex with various feedbacks and time lags that come into play, and can not be explained in term's of someone's simplistic expectations,» as an answer on the question why «this melting really was an indicator of Anthropogenic Global Warming»?

Understanding all the nuances of the climate system will take years (or more likely, is impossible for a single human brain), but anthropogenic global warming only needs three facts, two of which are probably reasonable, and the other which is not.

Given the increased levels of certainty regarding human - induced global warming (from 90 to 95 %), more robust projections on sea - level rise and data on melting of ice sheets, and the «carbon budget» for staying below the 2 °C target, the WGI conclusions together with other AR5 component reports are likely to put more pressure on the UNFCCC parties to deliver by 2015 an ambitious agreement that is capable of preventing dangerous anthropogenic interference with the climate system.

``... warming of the climate system is unequivocal... most of the global average warming over the past 50 years is very likely due to anthropogenic greenhouse gases increases...» — Rajendra Pachauri, Chairman of the IPCC, Nobel Prize acceptance speech, Dec. 10, 2007

As professional scientists, from students to senior professors, we uphold the findings of the IPCC Fourth Assessment Report, which concludes that «Warming of the climate system is unequivocal» and that «Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations».

Hence, avoiding dangerous levels of CO2 - induced warming is a necessary, albeit not always sufficient, condition for avoiding potentially dangerous anthropogenic interference in the climate system.

In summary, because of the effects of natural internal climate variability, we do not expect each year to be inexorably warmer than the preceding year, or each decade to be warmer than the last decade, even in the presence of strong anthropogenic forcing of the climate system.

While it is generally accepted that the observed reduction of the Northern Hemisphere spring snow cover extent (SCE) is linked to warming of the climate system caused by human induced greenhouse gas emissions, it has been difficult to robustly quantify the anthropogenic contribution to the observed change.

The main evidence for catastrophic anthropogenic global warming (CAGW), the principal alleged adverse effect of human emissions of carbon dioxide (CO2), is climate models built by CAGW supporters in a field where models with real predictive power do not exist and can not be built with any demonstrable accuracy beyond a week or two because climate and weather are coupled non-linear chaotic systems.

[Rob P]- The warming from 1910 - 1940, a time of weak anthropogenic (human - caused) forcing, matches the warm (positive) phase of the Interdecadal Pacific Oscillation (IPO)- the largest natural multidecadal oscillation in the climate system.

Here is a key point made by R&F (I removed the reference numbers for clarify of reading here — see the original paper for the links to the relevant peer - reviewed literature; GHG = greenhouse gases, CEWGA = committed equilibrium warming from greenhouse gases and aerosols, Wm2 = watts per metre squared, DAI = dangerous anthropogenic interference with the climate system):

The IPCC has already concluded that it is «virtually certain that human influence has warmed the global climate system» and that it is «extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010» is anthropogenic.1 Its new report outlines the future threats of further global warming: increased scarcity of food and fresh water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence.

According to the IPCC (2013), 93 % of the heat energy in the climate system claimed to be due to anthropogenic global warming is found in the oceans (AR5, Chapter 3).

The scientific consensus is that greenhouse gas (GHG) emissions from human agricultural and industrial activity are the principal cause of this global warming [1]--[3] and that such emissions must be severely curtailed to prevent further anthropogenic disruption of the climate system [4].
