They undergo full peer review and publication as a letter style article in one of the EGU interactive open-access journals. Their inclusion in EL depends upon recommendation by the chief/executive editors of the interactive journal and approval by the interdisciplinary <a href="https://www.egu-letters.net/editorial_board.html">editorial board</a> of the virtual magazine.</p> <p>Read <a href="https://www.egu-letters.net/about.html">more about EGU Letters</a>, the characteristics, and the editorial handling.</p> <h2>Participating EGU journals</h2> <ul> <li>Atmospheric Chemistry & Physics (<a href="https://www.atmospheric-chemistry-and-physics.net/" target="_blank">ACP</a>)</li> <li>Biogeosciences (<a href="https://biogeosciences.net/" target="_blank">BG</a>)</li> <li>Earth Surface Dynamics (<a href="https://www.earth-surface-dynamics.net/" target="_blank">ESurf</a>)</li> <li>Earth System Dynamics (<a href="https://www.earth-system-dynamics.net/" target="_blank">ESD</a>)</li> <li>Geoscience Communication (<a href="https://www.geoscience-communication.net/" target="_blank">GC</a>)</li> <li>Nonlinear Processes in Geophysics (<a href="https://www.nonlinear-processes-in-geophysics.net/" target="_blank">NPG</a>)</li> <li>Ocean Science (<a href="https://www.ocean-science.net/" target="_blank">OS</a>)</li> <li><a href="https://www.soil-journal.net/" target="_blank">SOIL</a></li> </ul></div><div id="recent_paper" class="cmsbox j-article j-article-section"><div id="recent-paper-content"> <div id="recent_paper_header"> <h2>Recent EGU Letters</h2> </div> <div class="grid-container paperlist-object in-range paperList-final" data-diff="0"> <div class="grid-100 hide-on-desktop hide-on-tablet"> <a class="paperlist-avatar" target="_blank" href="https://acp.copernicus.org/articles/24/11275/2024/acp-24-11275-2024-avatar-web.png"> <img class="img-responsive" src="https://acp.copernicus.org/articles/24/11275/2024/acp-24-11275-2024-avatar-thumb80.png" data-caption="© Author(s).

Here we show that climate models subject only to internal variability predict such warming spikes but rarely (<em>p</em>~1.6 %). However, when a prolonged La Niña immediately precedes an El Niño, as occurred leading up to 2023, such spikes are not uncommon (<em>p</em>~10.3 %). Virtually all of the spikes occur during an El Niño, strongly suggesting that internal variability drove the 2023 warming. </div> <div><a href="#" class="show-hide triangle" data-hide=".short_summary_121369" data-show=".short_summary_button_121369">Hide</a></div> </div> </div> <div class="j-widget__max ce_comment ce_comment_121369 mt-3" style="display: none"> <div class="widget dark-border"> <div class="legend journal-contentLinkColor">Executive editor</div> <div class="content"> The rapid increase in global warming in 2023 has sparked fears that Earth has entered a new warm state. Possible explanations for a warming spike have included transient changes in radiative forcing or deficiencies in climate models. This study shows that the primary cause is a mode of natural climate variability – the El Niño/Southern Oscillation (ENSO). The authors show that, while the magnitude of global warming caused by ENSO was particularly large in 2023, it is not unprecedented in the historical record. The implication is that global warming is continuing at a steady average rate without dramatic acceleration. </div> <div><a href="#" class="show-hide triangle" data-hide=".ce_comment_121369" data-show=".ce_comment_button_121369">Hide</a></div> </div> </div> </div> <div class="grid-15 tablet-grid-15 text-right hide-on-mobile"> <a class="paperlist-avatar" target="_blank" href="https://acp.copernicus.org/articles/24/11275/2024/acp-24-11275-2024-avatar-web.png"> <img class="img-responsive" src="https://acp.copernicus.org/articles/24/11275/2024/acp-24-11275-2024-avatar-thumb80.png" data-web="https://acp.copernicus.org/articles/24/11275/2024/acp-24-11275-2024-avatar-web.png" data-width="600" data-caption="© Author(s).

However, these events lack diversity, favoring wealthier countries and limiting opportunities for scholars from lower-income regions. Our study of the EGU meeting reveals that attendance is mostly influenced by a country's income. To promote inclusivity, we suggest rotating event locations, offering affordable accommodations, and establishing travel funds. These steps can help create a more diverse and innovative scientific community. </div> <div><a href="#" class="show-hide triangle" data-hide=".short_summary_120745" data-show=".short_summary_button_120745">Hide</a></div> </div> </div> <div class="j-widget__max ce_comment ce_comment_120745 mt-3" style="display: none"> <div class="widget dark-border"> <div class="legend journal-contentLinkColor">Executive editor</div> <div class="content"> We have selected this manuscript for inclusion in GC Letters because it addresses a critical and timely issue in the geosciences - economic barriers to participation in major scientific conferences, such as the European Geosciences Union (EGU) General Assembly. The study's findings highlight how financial constraints disproportionately affect scholars from lower-income countries, leading to significant underrepresentation and, consequently, a lack of diverse perspectives that are essential for scientific innovation and problem-solving in global challenges. By proposing actionable solutions to increase inclusivity, this manuscript contributes to ongoing discussions on equity in academia and aligns with our journal's commitment to promoting diversity and dismantling systemic barriers in the scientific community. </div> <div><a href="#" class="show-hide triangle" data-hide=".ce_comment_120745" data-show=".ce_comment_button_120745">Hide</a></div> </div> </div> </div> <div class="grid-15 tablet-grid-15 text-right hide-on-mobile"> <a class="paperlist-avatar" target="_blank" href="https://gc.copernicus.org/articles/7/245/2024/gc-7-245-2024-avatar-web.png"> <img class="img-responsive" src="https://gc.copernicus.org/articles/7/245/2024/gc-7-245-2024-avatar-thumb80.png" data-web="https://gc.copernicus.org/articles/7/245/2024/gc-7-245-2024-avatar-web.png" data-width="600" data-caption="© Author(s).

In this paper, we present a summary of past simultaneous heatwaves or cold spells and provide a computer program to enable other researchers to study them. </div> <div><a href="#" class="show-hide triangle" data-hide=".short_summary_117142" data-show=".short_summary_button_117142">Hide</a></div> </div> </div> <div class="j-widget__max ce_comment ce_comment_117142 mt-3" style="display: none"> <div class="widget dark-border"> <div class="legend journal-contentLinkColor">Chief editor</div> <div class="content"> Concurrent temperature extremes are becoming common but there is no climatology of such extremes in the literature.

To overcome the time-consuming computations of conventional data assimilation methods, this paper proposes using quantum annealing machines. Using the D-Wave quantum annealer, the proposed method found solutions with comparable accuracy to conventional approaches and significantly reduced computational time. </div> <div><a href="#" class="show-hide triangle" data-hide=".short_summary_113313" data-show=".short_summary_button_113313">Hide</a></div> </div> </div> </div> <div class="grid-15 tablet-grid-15 text-right hide-on-mobile"> <a class="paperlist-avatar" target="_blank" href="https://npg.copernicus.org/articles/31/237/2024/npg-31-237-2024-avatar-web.png"> <img class="img-responsive" src="https://npg.copernicus.org/articles/31/237/2024/npg-31-237-2024-avatar-thumb80.png" data-web="https://npg.copernicus.org/articles/31/237/2024/npg-31-237-2024-avatar-web.png" data-width="600" data-caption="© Author(s).
