Turbulent heat flux dynamics along the Dotson and Getz ice-shelf fronts (Amundsen Sea, Antarctica) by B. Jacob, B. Y. Queste, M. D. du Plessis

“…By obtaining the reconstructed flux, the reduced heat loss bias (12 W m<span class="inline-formula">⁻²</span>) reduced the seasonal bias in sea surface temperature (heat content) to <span class="inline-formula">−</span>0.17 °C (<span class="inline-formula">−</span>3.30 <span class="inline-formula">×</span> 10<span class="inline-formula">⁷</span> J) over the 35 d. …”

Ice-nucleating particles active below −24&thinsp;°C in a Finnish boreal forest and their relationship to bioaerosols by F. Vogel, F. Vogel, M. P. Adams, L. Lacher, P. B. Foster, G. C. E. Porter, G. C. E. Porter, B. Bertozzi, B. Bertozzi, K. Höhler, J. Schneider, T. Schorr, N. S. Umo, J. Nadolny, Z. Brasseur, P. Heikkilä, E. S. Thomson, N. Büttner, M. I. Daily, R. Fösig, A. D. Harrison, J. Keskinen, U. Proske, U. Proske, U. Proske, J. Duplissy, J. Duplissy, M. Kulmala, T. Petäjä, O. Möhler, B. J. Murray

“…Boreal forests are known as sources of bioaerosol, and recent work indicates that these dominate the INP spectra above <span class="inline-formula">−</span>24 <span class="inline-formula">°C</span>. To quantify the INP population at temperatures below <span class="inline-formula">−</span>24 <span class="inline-formula">°C</span>, we deployed a portable cloud expansion chamber (PINE) in a Finnish boreal forest from 13 March 2018 to 11 May 2018. …”

Considerations for determining warm-water coral reef tipping points by P. Pearce-Kelly, A. H. Altieri, J. F. Bruno, C. E. Cornwall, M. McField, A. I. Muñiz-Castillo, J. Rocha, R. O. Setter, C. Sheppard, R. M. Roman-Cuesta, C. Yesson

“…Considering observed and projected stressor impacts, we endorse the global tipping point revision's conclusion of a global mean surface temperature (relative to pre-industrial) tipping point threshold of 1.2 <span class="inline-formula">°C</span> (range 1–1.5 <span class="inline-formula">°C</span>) and the long-term impacts of atmospheric <span class="inline-formula">CO₂</span> concentrations above 350 ppm, while acknowledging that comprehensive assessment of stressors, including ocean warming response dynamics, overshoot, and cascading impacts, have yet to be sufficiently realised. …”
