From "It's the Anomalies, Stupid" (apologies to @GStephanopoulos) in "The Hockey Stick & the Climate Wars" (#HSCW amazon.com/Hockey-Stick-C…).
Time we start taking seriously the possibility that climate models are missing a La Nina (rather than El Nino)-like response to warming.
Time we start taking seriously the possibility that climate models are missing a La Nina (rather than El Nino)-like response to warming.
Here's an article we published in @Nature back in 2003 that was suggestive of a La Nina-like response to warming (via paleoclimate evidence for an El Nino-like response to volcanic cooling): nature.com/articles/natur…
Here's some followup modeling work we did (Journal of Climatee, 2005) that reproduces the relationship seen in the proxy data: journals.ametsoc.org/view/journals/…
Twenty five years ago, on this #EarthDay, Apr 22 1998, the #HockeyStick reconstruction of temperatures was born (nature.com/articles/33859). Here's an interview I did on @CBSEveningNews with @johnrobertsFox (anchor @DanRather):

The Hockey Stick was extended to the past 1000 years in 1999 (agupubs.onlinelibrary.wiley.com/doi/10.1029/19…) and appeared in it's most recognizable form in the @IPCC_CH 3rd Assessment Report "Summary for Policymakers" (ipcc.ch/site/assets/up…)
Sorry #DenierBots, the original #HockeyStick was readily reproduced with publicly available data & methods description by other researchers:

Valerie Trouet verkondigt de belangrijkste 3 mythes over #Climategate. Steve McIntyre en Ross McKitrick hebben deze mythes eind 2019 weerlegd in dit document [M&M 2019]: climateaudit.info/pdf/climategat… Samenvatting: 2/

June 2020 temperature anomalies in Arctic Siberia were striking.
The maximum temperature anomaly in ERA5 0.25° gridded data was 10.3°C, which is the highest value in the Northern Hemisphere at any summer month since 1979 (so in the whole dataset).

Verkhoyansk, Russia has been widely in the news for its all-time heat record set in June 2020.
The recent temperature trend during the past three years in the month of June looks certainly worrying. #HockeyStick
