“absorbed solar radiation at the top of the atmosphere in early summer (May–July) plays a precursory role in determining the Arctic sea ice concentration in late summer (August–October)”
“this intimate delayed…relationship is not represented in most of current climate models. Rather, the models tend to over-emphasize internal sea ice processes in summer.”
Alarmists ignore the unspeakable all-time record highs in Antarctic sea ice extent broken over each of the past three years, as do climate models, which laughably predicted the opposite of a decrease in Antarctic sea ice extent more so than Arctic sea ice.
Alarmists also claim current Arctic sea ice changes are “unprecedented” while ignoring proxy data indicating Arctic sea ice was much less than present-day during the Holocene Climate Optimum ~6,000 years ago, Arctic temperatures were warmer than the present multiple times over past 1357 years, the Medieval Warming Period in the Arctic was warmer than the present, Alaskan glaciers are about the same size as during the Medieval Warm Period, etc., etc.
Connecting early summer cloud-controlled sunlight and late summer sea ice in the Arctic
This study demonstrates that absorbed solar radiation (ASR) at the top of the atmosphere in early summer (May–July) plays a precursory role in determining the Arctic sea ice concentration (SIC) in late summer (August–October). The monthly ASR anomalies are obtained over the Arctic Ocean (65°N–90°N) from the Clouds and the Earth’s Radiant Energy System during 2000–2013. The ASR [absorbed solar radiation] changes primarily with cloud variation. We found that the ASR [absorbed solar radiation] anomaly in early summer is significantly correlated with the SIC [Arctic sea ice concentration] anomaly in late summer (correlation coefficient, r ≈ −0.8 with a lag of 1 to 4 months). The region exhibiting high (low) ASR anomalies and low (high) SIC anomalies varies yearly. The possible reason is that the solar heat input to ice is most effectively affected by the cloud shielding effect under the maximum TOA solar radiation in June and amplified by the ice-albedo feedback. This intimate delayed ASR-SIC relationship is not represented in most of current climate models. Rather, the models tend to over-emphasize internal sea ice processes in summer.
I’ve been wondering if the cloud cover persists at significantly higher millibars than before especially during the autumn / beginning of the winter season in Finland. It seems to do so althrough I haven’t collected any weather data despite being stormchaser for years (because that isn’t important regarding to the hobby).
Is this their reasoning as to why the Arctic ice hasn’t already disappeared?
“””””…..“absorbed solar radiation at the top of the atmosphere in early summer (May–July) plays a precursory role in determining the Arctic sea ice concentration in late summer (August–October)”……””””””
So translating that into English, just what are these authors saying (if anything) ??
Solar radiation gets absorbed at the top of the atmosphere 24 hours a day, 365 1/4 days a year, so just what is special about May-June and August-October.
What does “plays a precursory role” mean.
And it would seem that this pattern has repeated over millions of years of playing a precursory role.
So they don’t mention any other factors, besides playing a precursory role, so just what are they reporting on ??
