Because the arctic temperature record would probably not require any of the climategate urban heat island adjustments it would seem to definitively sustain that global temperatures are significantly rising. This would seem to form the most unequivocal and verifiable proof that rhetoric to the contrary is simply false.

  • $\begingroup$ No educated person doubts that there is climate change, for the simple reason there always has been for the last 4 billion years, and the trend at the moment is one of warming. How much of it is due to man-made emissions is debatable. One wonders how many more ways you can find of serving up the same question. $\endgroup$

  • $\begingroup$ @MichaelWalsby I must deconstruct every subtle nuance of climate change denial one key element at a time. The key element that seems to be utterly deconstructed here is that applying any weight what-so-ever to climate-gate rhetoric is incorrect. We can know for sure that the global temperature record is accurate on the basis that the Arctic temperature record sustains it. $\endgroup$

    $\begingroup$ @ polcott I am totally against censorship and believe everyone should be allowed to have their say, even holocaust deniers. The rioters in Hong Kong claim to be rioting for more freedom and democracy, yet they attacked and seriously injured someone who took the central government's point of view. What is democratic about that? Freedom of speech is one of the main pillars of democracy. I am probably the only user with 2,000-plus reputation who has never downvoted anybody. The system is wide open to abuse, so I am boycotting it. $\endgroup$

The recent spike in Greenland temperatures is almost at Holocene maximum levels despite the declining trend over the last 7,000 years.

Greenland ice cores provide a high-quality high-resolution estimate of past changes in temperatures, allowing more precise comparisons with observed temperature records than most other climate proxies. While current temperatures are likely still below the highs in the early Holocene around 7,000 years ago, they are clearly higher than any temperatures experienced in Greenland over the past 2,000 years.

Greenland is just one location and temperature variations seen in ice core records may not be characteristic of global temperatures. However, global proxy reconstructions have tended to show similar patterns, with current temperatures lower than the early Holocene maximum.
