Ariadne<p>On 21. April the <a href="https://kolektiva.social/tags/WMO" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WMO</span></a> (World Meteorological Organization) released their "State of the Global Climate 2022" annual report. There is no good news at all for the <a href="https://kolektiva.social/tags/climate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>climate</span></a>; the <a href="https://kolektiva.social/tags/ClimateCrisis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ClimateCrisis</span></a> is in full-swing.

There are many excellent graphics in the report; I've only highlighted one of them here.</p><p><a href="https://kolektiva.social/tags/GHG" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GHG</span></a> - Concentrations of the three main greenhouse gases – carbon dioxide <a href="https://kolektiva.social/tags/CO2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CO2</span></a>, <a href="https://kolektiva.social/tags/methane" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>methane</span></a> and <a href="https://kolektiva.social/tags/NitrousOxide" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>NitrousOxide</span></a> – reached record highs in 2021, the latest year for which consolidated global values are available (1984–2021).The annual increase in methane concentration from 2020 to 2021 was the highest on record. Real-time data from specific locations show that levels of the three <a href="https://kolektiva.social/tags/GreenhouseGases" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>GreenhouseGases</span></a> continued to increase in 2022.</p><p><a href="https://kolektiva.social/tags/Ocean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Ocean</span></a> heating - Around 90% of the energy trapped in the climate system by greenhouse gases goes into the ocean. Ocean heat content, which measures this gain in energy, reached a new observed record high in 2022.</p><p><a href="https://kolektiva.social/tags/MarineHeatwave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MarineHeatwave</span></a> - Despite continuing La Niña conditions, 58% of the ocean surface experienced at least one <a href="https://kolektiva.social/tags/marine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>marine</span></a> <a href="https://kolektiva.social/tags/heatwave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>heatwave</span></a> during 2022. In contrast, only 25% of the ocean surface experienced a marine cold spell.</p><p><a href="https://kolektiva.social/tags/SeaLevelRise" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SeaLevelRise</span></a> - Global mean sea level continued to rise in 2022, reaching a new record high for the satellite altimeter record (1993–2022). The rate of global mean sea level <a href="https://kolektiva.social/tags/MSL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MSL</span></a> rise has doubled between the first decade of the satellite record (1993–2002, 2.27 mm per year) and the last (2013–2022, 4.62 mm per year).</p><p><a href="https://kolektiva.social/tags/Glacier" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Glacier</span></a> melting - In the hydrological year 2021/2022, a set of reference glaciers with long-term observations experienced an average mass balance of −1.18 metres water equivalent (m w.e.). This loss is much larger than the average over the last decade. Six of the ten most negative mass balance years on record (1950– 2022) occurred since 2015. The cumulative mass balance since 1970 amounts to more than −26 m w.e.</p><p><a href="https://kolektiva.social/tags/Drought" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Drought</span></a> in <a href="https://kolektiva.social/tags/WetSeason" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>WetSeason</span></a>, <a href="https://kolektiva.social/tags/food" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>food</span></a> insecurity - In East <a href="https://kolektiva.social/tags/Africa" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Africa</span></a>, rainfall has been below average in five consecutive wet seasons, the longest such sequence in 40 years. As of August 2022, an estimated 37 million people faced acute food insecurity across the region, under the effects of the drought and other shocks.</p><p><a href="https://kolektiva.social/tags/Flooding" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Flooding</span></a> - Record-breaking rain in July and August led to extensive flooding in <a href="https://kolektiva.social/tags/Pakistan" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Pakistan</span></a>.There were at least 1 700 deaths, and 33 million people were affected, while almost 8 million people were displaced. Total damage and economic losses were assessed at US$ 30 billion.</p><p><a href="https://kolektiva.social/tags/Heatwave" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Heatwave</span></a> - Record-breaking heatwaves affected <a href="https://kolektiva.social/tags/China" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>China</span></a> and <a href="https://kolektiva.social/tags/Europe" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Europe</span></a> during the summer. In some areas, extreme heat was coupled with exceptionally dry conditions.
