Arctic sea ice volume continues to grow

“Last year had the highest June Arctic sea ice volume since 2006, and this year is well ahead of last year.” click here

Arctic sea ice volume is increasing

“Arctic sea ice volume gain from January 1-23 has been second highest in the Danish Meteorological Institute record, just behind 2008.” click here  and here

Arctic sea ice volume increasing

“Ten years ago, America’s leading Arctic experts said the climate had passed the tipping point, and the Arctic could be ice-free between 2013 and 2018. The exact opposite has happened. Arctic sea ice volume is up 30% over the past ten years.” click here

Predictions of Arctic sea ice demise are not science-based

“There has been no trend in Arctic sea ice extent over the last twelve years. But climate scientists aren’t interested in facts.” click here

Arctic ice increase….hockey stick?

“No one knows how long this divergence of surplus ice will persist, but for now 2018 Arctic ice extent resembles a hockey stick.  Presently the ice is 525.000 km^2 above 11 year average (2007 to 2017 inclusive) and  ~1M km^2 greater than 2007.” click here

Debunking fake climate claims regarding arctic sea ice

“James Hansen was dead wrong about all of his forecasts over the past 30 years, so fake climate scientists and the fake news press have quite predictably ramped up their lies and claim the exact opposite.” click here

No direct effects of ocean acidification observed in Arctic specie

Peter Thor, Fanny Vermandele, Marie-Helene Carignan, Sarah Jacque, Piero Calosi.  No maternal or direct effects of ocean acidification on egg hatching in the Arctic copepod Calanus glacialis PLOS ONE 13(2): e0192496. https://doi.org/10.1371/journal.pone.0192496

Widespread ocean acidification (OA) is transforming the chemistry of the global ocean and the Arctic is recognised as the region where this transformation will occur at the fastest rate. Moreover, many Arctic species are considered less capable of tolerating OA due to their lower capacity for acid-base regulation. This inability may put severe restraints on many fundamental functions, such as growth and reproductive investments, which ultimately may result in reduced fitness. However, maternal effects may alleviate severe effects on the offspring rendering them more tolerant to OA. In a highly replicated experiment we studied maternal and direct effects of OA predicted for the Arctic shelf seas on egg hatching time and success in the keystone copepod species Calanus glacialis. We incubated females at present day conditions (pHT 8.0) and year 2100 extreme conditions (pHT 7.5) during oogenesis and subsequently reciprocally transplanted laid eggs between these two conditions. Statistical tests showed no effects of maternal or direct exposure to OA at this level. We hypothesise that Cglacialis may be physiologically adapted to egg production at low pH since oogenesis can also take place at conditions of potentially low haemolymph pH of the mother during hibernation in the deep.
