The Summary. A new report describes the dire state of Earth’s snow and ice. Among other findings, it warns that several key climate tipping points appear more likely to be reached than ...
AMOC-Index since 900 CE with pronounced slowdown since ~1850; Rahmstorf et al. (2015) [5] Climate scientists Michael Mann of Penn State and Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research suggested that the observed cold pattern during years of temperature records is a sign that the Atlantic Ocean's Meridional overturning circulation (AMOC) may be weakening.
Evidence for a multidecadal climate oscillation centered in the North Atlantic began to emerge in 1980s work by Folland and colleagues, seen in Fig. 2.d.A. [5] That oscillation was the sole focus of Schlesinger and Ramankutty in 1994, [6] but the actual term Atlantic Multidecadal Oscillation (AMO) was coined by Michael Mann in a 2000 telephone interview with Richard Kerr, [7] as recounted by ...
The AMOC includes Atlantic currents at the surface and at great depths that are driven by changes in weather, temperature and salinity. Those currents comprise half of the global thermohaline circulation that includes the flow of major ocean currents, the other half being the Southern Ocean overturning circulation .
The Washington Post looked back at the end of the last ice age, when studies suggest a “flood of freshwater spilled into the Atlantic, halting the AMOC and plunging much of the Northern ...
In the northern, western hemisphere, it is called the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a critical part of the Earth’s energy balance which regulates the climate.
The Atlantic Equatorial Mode or Atlantic Niño is a quasiperiodic interannual climate pattern of the equatorial Atlantic Ocean. It is the dominant mode of year-to-year variability that results in alternating warming and cooling episodes of sea surface temperatures accompanied by changes in atmospheric circulation. [ 1 ]
New study finds evidence of an unprecedented slowdown in North Atlantic Ocean circulation, likely to due to human-caused climate change.
