Is AMOC More Predictable than North Atlantic Heat Content?

11 Climate Change: Is It More Predictable Than We Think?

Is a decline of AMOC causing the warming hole above the North Atlantic in observed and modeled warming patterns?

The pattern of Global Mean Temperature (GMT) change is calculated by regressing local Surface Air Temperature (SAT) to GMT for an ensemble of CMIP5 models and for observations over the last 132 years. Calculations are based on the historical period and climate change scenarios. As in the observations the warming-pattern contains a warming hole over the subpolar North Atlantic. Using a bivariate...

Heat content variability in the North Atlantic Ocean in ocean reanalyses.

Warming of the North Atlantic Ocean from the 1950s to 2012 is analyzed on neutral density surfaces and vertical levels in the upper 2000 m. Three reanalyses and two observational data sets are compared. The net gain of 5 × 1022 J in the upper 2000 m is roughly 30% of the global ocean warming over this period. Upper ocean heat content (OHC) is dominated in most regions by heat transport converge...

The spatial pattern and mechanisms of heat-content change in the North Atlantic.

The total heat gained by the North Atlantic Ocean over the past 50 years is equivalent to a basinwide increase in the flux of heat across the ocean surface of 0.4 +/- 0.05 watts per square meter. We show, however, that this basin has not warmed uniformly: Although the tropics and subtropics have warmed, the subpolar ocean has cooled. These regional differences require local surface heat flux ch...

PI3K and mTOR inhibitor, NVP-BEZ235, is more toxic than X-rays in prostate cancer cells

Background: Radiotherapy and adjuvant androgen deprivation therapy have historically been the first treatment choices for prostate cancer but treatment resistance often limits the capacity to effectively manage the disease. Therefore, alternative therapeutic approaches are needed. Here, the efficacies of radiotherapy and targeting the pro-survival cell signaling components epidermal growth fact...
