Verdensorganisationen har skabt stadig stærkere fælles fodslag og er en nødvendig playmaker for den fælles indsats for at undgå farlige menneskabte temperaturændringer.
La oss være optimister og tenke oss frem til en verden i 2040 der klimamålene er nådd. Her må vi som Hornburg og Sending peker på i sin artikkel i forrige nummer av Internasjonal politikk tenke ...internasjonalt, også om perspektivet er Norge. Hva slags scenarier kan ligge til grunn for en slik utvikling? Artikkelen trekker opp tre slike. Det ene er at USA og Kina slår seg sammen i et klimanøytralt energikartell. Gjennom bruk av både handelsmakt og militær makt presser de frem et belte av kjernekraftverk og fornybare kraftkilder støttet opp av amerikansk teknologi og kinesisk industri. Det andre er at tingene går sin skjeve gang og at klimaets «vippepunkt» passeres. Ekstremvær, tørke og havstigning skaper større ødeleggelser enn finansmarkedet kan bære, produksjon og handel stopper opp og utslippene synker. Det tredje er en utvikling hvor marked og stater går sammen om forskning, utvikling og gjennomføring av nødvendige tiltak. Dette krever internasjonalt samarbeid om offentlige regulering og innovative bedrifter som sammen med statene kan satse på teknologisk og sosial utvikling. Bare i det siste scenariet vil vi kunne redde både klodens klima og demokratiet som styringsform.
Die ökologische und klimatische Katastrophe gefährdet die Grundfesten unserer planetaren Existenzbedingungen. Angesichts der dadurch verursachten Zerstörungen plädiert Jürgen Manemann für eine ...rettende Umweltphilosophie. Diese erschüttert die Kaltstellungen des wissenschaftlich-technischen Zugriffs auf Natur durch die Konfrontation mit Andersheit und Anderheit in Natur. Rettende Umweltphilosophie zielt auf ein (Zusammen-)Leben, das alle Menschen, Tiere, Pflanzen, Arten, Berge, Flüsse, Ökosysteme und die Erde als Teil der Moralgemeinschaft umfasst. Indem sie sich engagierend und aktivierend um die Handlungsfähigkeit der Menschen sorgt, begründet sie eine Pflicht zum Aktivismus. Rettende Umweltphilosophie schärft den Blick für Utopisches und lässt Neues im Kaputten und in Zwischenräumen aufblitzen.
Results of the study revealed that when dust impinged on the surface of the PV modules, monthly maximum power output of a 1.5 kWp system in Perth, Australia and a 50 Wp system in Nusa Tenggara Timur ...(NTT), Indonesia decreased, on average, by about 4.5% and 8%, respectively. Economic modelling showed that, the cost of production per kWh lost due to dust exhibited by these systems were A$ 0.26/kWh and A$ 0.15/kWh, respectively. Comparison of the cost of energy losses and maintenance revealed that, the Perth system would require manual cleaning in October while the system in NTT would require cleaning in August and October. Although the saving in production losses is not economically significant, this cleaning schedule was recommended, particularly for small systems in NTT since the extra output can have a significant effect on the quality of life in remote villages. The key finding was that higher dust de-rating factors and more cleaning activity may be more appropriate for PV systems deployed in tropical climate areas than that in temperate climate regions. It is recommended that PV system Standards that use the 5% performance de-rating factor due to soiling are reviewed and consideration given to climate-dependent de-rating factors.
•Energy losses of a 1.5 kWp in Perth, Australia and a 50 Wp in NTT, Indonesia were 113.54 and 7.11 kWh/year, respectively.•Time to perform a manual cleaning was in October for the system in Perth, while in August and October for the system in NTT.•A higher dust de-rating factor is required for PV systems deployed in tropical climate areas.
Artikkelen er inspirert av et avisinnlegg skrevet av Auke Lont, Harald Norvik og Peter Melby der de tar til orde for at framtidige oljeinntekter bør går til klimatiltak i andre land i stedet for til ...ytterligere innskudd i det nåværende oljefondet. Artikkelen beskriver den norske oljepolitikken fra tidlig 1960-tall til i dag. Den har vært en udelt suksess som har tjent Norge godt. Men norsk oljeproduksjon har bidratt til store utslipp av CO2. Det er den moralske begrunnelsen for at framtidige norske oljeinntekter bør brukes til klimatiltak.

Marine heatwaves (MHWs) are periods of extreme warm sea surface temperature that persist for days to months
and can extend up to thousands of kilometres
. Some of the recently observed marine ...heatwaves revealed the high vulnerability of marine ecosystems
and fisheries
to such extreme climate events. Yet our knowledge about past occurrences
and the future progression of MHWs is very limited. Here we use satellite observations and a suite of Earth system model simulations to show that MHWs have already become longer-lasting and more frequent, extensive and intense in the past few decades, and that this trend will accelerate under further global warming. Between 1982 and 2016, we detect a doubling in the number of MHW days, and this number is projected to further increase on average by a factor of 16 for global warming of 1.5 degrees Celsius relative to preindustrial levels and by a factor of 23 for global warming of 2.0 degrees Celsius. However, current national policies for the reduction of global carbon emissions are predicted to result in global warming of about 3.5 degrees Celsius by the end of the twenty-first century
, for which models project an average increase in the probability of MHWs by a factor of 41. At this level of warming, MHWs have an average spatial extent that is 21 times bigger than in preindustrial times, last on average 112 days and reach maximum sea surface temperature anomaly intensities of 2.5 degrees Celsius. The largest changes are projected to occur in the western tropical Pacific and Arctic oceans. Today, 87 per cent of MHWs are attributable to human-induced warming, with this ratio increasing to nearly 100 per cent under any global warming scenario exceeding 2 degrees Celsius. Our results suggest that MHWs will become very frequent and extreme under global warming, probably pushing marine organisms and ecosystems to the limits of their resilience and even beyond, which could cause irreversible changes.

Drawing from tenets of self-determination theory, we propose and test a multilevel model that examines the effects of employee involvement climate on the individual-level process linking employee ...regulatory focus (promotion and prevention) to innovation via thriving. Using data collected at three points in time from 346 participants in 75 groups, multilevel path analytic results demonstrated support for a positive indirect effect from promotion focus to innovation via thriving and a negative indirect effect from prevention focus to innovation via thriving. In addition, results showed a positive indirect effect from employee involvement climate to innovation via thriving. Perhaps most important, cross-level moderated mediation results demonstrated that employee involvement climate strengthens the relationship between promotion focus and thriving, which, in turn, positively relates to innovation. The theoretical and practical implications of these multilevel effects on innovation are discussed.
Die sozialökologische Transformation ist in aller Munde. Dies gilt sowohl für die politischen Debatten wie auch für die Wissenschaft. Dabei wird zunehmend deutlich: Multiple Krisen lassen sich nicht ...mehr nur mit Hilfe schrittweiser (Umwelt-)Politiken lösen, sondern es sind strukturelle Veränderungen notwendig. Die Beiträger*innen des Bandes arbeiten Gerechtigkeitsfragen und die gesellschaftspolitische Brisanz ökologischer Verteilungskonflikte im Kontext der Transformation heraus. Durch ihre Analysen unter Bezugnahme auf unterschiedliche Dimensionen von Umweltgerechtigkeit machen sie diese greifbar und liefern Kontextwissen für eine längst überfällige Diskussion.
