- NASA: VOLCANIC ACTIVITY IS HEATING UP ANTARCTICA’S ICE SHEET
Scientists have been debating whether or not mantle plume heat contributes to western Antarctica’s instability. Some recent studies provided evidence this might be the case, but even this study’s authors were skeptical. “I thought it was crazy,” Hélène Seroussi, the study’s co-author and scientist at NASA’s Jet Propulsion Laboratory, said in a release. “I didn’t see how we could have that amount of heat and still have ice on top of it,” Seroussi said in a statement. NASA says Seroussi’s study provides more evidence of geothermal activity underneath a portion of the world’s largest ice sheet.
- Scientists: ‘Loud Divergence Between Sea Level Reality And Climate Change Theory’
Global Sea Level ‘Acceleration’ Just 0.002 mm/year²
Sea level rise failing to cooperate:
1. East Antarctica, which comprises two-thirds of the continent, has been gaining mass since 2003 (Martín-Español et al., 2017).
2. The Western Antarctic Peninsula has been rapidly cooling since 1999 (-0.47°C per decade), reversing the previous warming trend and leading to “a shift to surface mass gains of the peripheral glacier” (Oliva et al., 2017).
3. The Greenland ice sheet (GIS) has been melting so slowly and so negligibly in recent decades that the entire ice sheet’s total contribution to global sea level rise was a mere 0.39 of a centimeter (0.17 to 0.61 cm) between 1993 and 2010 (Leeson et al, 2017) . That’s a sea level rise contribution of about 0.23 mm/year since the 1990s, which is a canyon-sized divergence from the 61 mm/year that adherents of peer-reviewed, “consensus” climate science have projected for the coming decades.
And now Australian scientists have published a new paper in the journal Earth Systems and Environment that “does not support the notion of rapidly changing mass of ice in Greenland and Antarctica“. The paper highlights the “loud divergence between sea level reality” and “the climate models [that] predict an accelerated sea-level rise driven by the anthropogenic CO2 emission."
Global Sea Levels Actually Rising About 1 mm/yr… Not 3+ mm/yr -- McAneney et al., 2017: Global averaged sea-level rise is estimated at about 1.7 ± 0.2 mm year−1 (Rhein et al. 2013), however, this global average rise ignores any local land movements. Church et al. (2006) and J. A. Church (2016; personal communication) suggest a long-term average rate of relative (ocean relative to land) sea-level rise of ∼1.3 mm year. …
