Ocean surface warming in Krossfjorden, Svalbard, during the last 60 years

Arctic Ocean surface warming trends over the past 100 years

[1] Ocean temperature profiles and satellite data have been analyzed for summertime sea surface temperature (SST) and upper ocean heat content variations over the past century, with a focus on the Arctic Ocean peripheral seas. We find that many areas cooled up to 0.5 C per decade during 1930–1965 as the Arctic Oscillation (AO) index generally fell, while these areas warmed during 1965–1995 as t...

Tracking ocean heat uptake during the surface warming hiatus.

Ocean heat uptake is observed to penetrate deep into the Atlantic and Southern Oceans during the recent hiatus of global warming. Here we show that the deep heat penetration in these two basins is not unique to the hiatus but is characteristic of anthropogenic warming and merely reflects the depth of the mean meridional overturning circulation in the basin. We find, however, that heat redistrib...

Experiments of the last 60 years

Radiation accidents over the last 60 years.

Since the end of the Second World War, industrial and medical uses of radiation have been considerably increasing. Accidental overexposures of persons, in either the occupational or public field, have caused deaths and severe injuries and complications. The rate of severe accidents seems to increase with time, especially those involving the public; in addition, accidents are often not immediate...

America`s Strategies against IR during the Last Forty Years

The Islamic Revolution, as the greatest historical evolution of contemporary times, has caused America`s interests face many challenges. Understanding the tools and strategies used by the United States against the Islamic Republic of Iran helps us to better understand and confront the country. In this regard, using the theory of invasive realism, American strategies against the Islamic Republic...
