@AgroClim Interesting. Are you able to provide publication details for the maize yield data shown above?

Some important climate work from Mfabeni peatland @iSimangalisoZA Thanks to @susanne_fietz for leading the work!

[SusanneFietz @susanne_fietz]

Thanks for sharing, it's finally out "on paper"! Last c. 43k years of air temperature in southern east Africa from two peat cores. A fabulous collaboration of South African and European research teams. #paleotemperature #gdgt #peat @david_naafs @FP_GDGT @HumphriesMarc

Rewarding experience working with @newfcongress on the lead croc story at Lake St Lucia @iSimangalisoZA

Looking forward to the film being showcased at @conservationsym next month! 🎥 🐊

[AECTSpringerNature @AECTSpringerNat]

The Oct. issue of AECT describes a study of metals in crocodile eggs from Lake St Lucia, South Africa. Levels of metals in eggs, incl. Pb were relatively low, considering that adult crocodiles from the lake have the highest blood Pb concentrations recorded globally in wildlife 1/
