Near real-time Yahoo stock quotes in Excel

You may know that Yahoo Finance has for a long time provided near real-time global stock quotes via its website and via a web API service, which many have used as a convenient source for Excel data. There have been lots of VBA implementations and even a direct spreadsheet formula implementation (no VBA).

Unfortunately the API service was abused to the extent that some even purported to sell trading applications based around it (go figure). That resulted in a huge . . . → Read More: Near real-time Yahoo stock quotes in Excel

Updating the global temperature graphs

The fuss recently about a fairly minor fix to the fairly ordinary estimate of global temperature change provided by satellite remote sensing has prompted some long-overdue action from me. I’ve updated and I hope improved all the global temperature graphs

Season 2016 roundup

Deep Creek snow depth

The 2016 Australian snow season was a good one by modern standards, even though the peak snowpack depth of 170.5 cm¹ was well below the long term (62-year) average of 197 cm. The season was late to start — the first measured depth was on 23 June — and very late to finish (last depth 22 November). Ongoing snowfalls up high through the second half of the season kept the cover and surface in better than usual shape … but one of . . . → Read More: Season 2016 roundup

Snyder and the global temperature graph

A paper in this week’s Nature by Caroline Snyder at Stanford provides a fresh attempt at estimating global average surface temperatures across the Pleistocene (her estimates cover the last 2 million years).

Th' th' th' th' th' that's all folks

Update (26 September):

This one’s looking quite interesting now on the Bureau of Meteorology’s 4-day chart, which of course is drawn off the excellent European ECMWF model (for historical reasons…).
