“…Additionally, there is likely little to gain as aerial insect abundance is reduced, even in warm temperatures [89]. Hibernation rTL could provide insight into seasonal effects and how bats might cope with predicted increases in winter temperature and rainfall under future climate change scenarios [87]. Interestingly, while there are yearly effects on rTL, withinindividual increases and/or maintenance of telomere length in some individuals occurred during hibernation after accounting for weather conditions.…”

Hibernation is linked with various hypotheses to explain the extended lifespan of hibernating mammals compared with their non-hibernating counterparts. Studies on telomeres, markers of ageing and somatic maintenance, suggest telomere shortening slows during hibernation, and lengthening may reflect self-maintenance with favourable conditions. Bats in temperate zones adjust body temperatures during winter torpor to conserve energy and exploit mild conditions for foraging. Climate change may impact the hibernation cycle of bats, but more research is needed regarding the role of telomeres in understanding their response to a changing climate. Here, relative telomere length (rTL) was measured in the long-lived greater horseshoe bat Rhinolophus ferrumequinum ( n = 223 individuals) over three winters, considering climatic conditions. Cross-sectional analyses revealed between-individual variation in rTL with a strong year effect, likely linked to varying weather conditions and foraging success. Additionally, within-individual increases of rTL occurred in 51% of consecutive measurements, with evidence of increasing telomerase expression during hibernation in this species. These findings highlight the beneficial effects of hibernation on telomeres and potential consequences of changing climatic conditions for long-lived temperate bats. Understanding the interplay between hibernation, telomeres, and climate can provide insights into the adaptive capacity and survival of bat populations facing environmental challenges.

“…Elsewhere over the summer and autumn, unsettled conditions prevailed, with isolated intense rainfall events impacting central England in June and July. The autumn/winter of 2019/2020 was exceptionally wet for the UK as a whole and was associated with record-breaking flooding in parts of central Britain (Davies et al, 2021;Sefton et al, 2021).…”

“…In this case an opposite but symmetric surface response results, with strong positive NAO. A very recent example occurred in February 2020, when, following an extremely strong polar vortex (Hardiman et al, 2020b;Lee et al, 2020b;Lawrence et al, 2020;Rao et al, 2021a), the tropospheric jet in the Atlantic sector strengthened, and the associated increased storminess and rainfall in this case resulted in UK monthly rainfall reaching a new record high (Davies et al, 2021).…”

Abstract. Over recent years there have been parallel advances in the development of stratosphere resolving numerical models, our understanding of stratosphere-troposphere interaction and the extension of long-range forecasts to explicitly include the stratosphere. These advances are now allowing new and improved capability in long range prediction. We present an overview of this development and show how the inclusion of the stratosphere in forecast systems aids monthly, seasonal and decadal climate predictions. We end with an outlook towards the future of climate forecasts and identify areas for improvement that could further benefit these rapidly evolving predictions.
