Week in review – science edition

by Judith Curry

A few things that caught my eye this past week.

Uncertainty quantification of the multi-centennial response of the Antarctic ice sheet to climate change 

“India’s Depleting Groundwater: When Science Meets Policy”

Regime shift of global oceanic evaporation in the late 1990s [link]

2018 Florida Red Tide caused by ocean circulation, not climate change

Ito et al. (2019) “used a computational model of circulation and cycling of elements in the ocean to simulate [changes in seawater oxygen levels in the North Pacific] for the last approximately 70 years” and to understand their causes.  

A new 200‐year spatial reconstruction of West Antarctic surface mass balance

Regime shifts of Mediterranean forest carbon uptake and reduced resilience driven by multidecadal ocean surface temperatures

Identifying strong signals between low‐frequency climate oscillations and annual precipitation using long‐window correlation analysis

Observation-based estimate of global and basin ocean meridional heat transport time series

Constraining the aerosol influence on cloud liquid water path

A key factor initiating surface ablation of Arctic sea ice: earlier and increasing liquid precipitation (open access)

Effects of deforestation on the onset of the rainy season and the duration of dry spells in southern Amazonia

Non-uniform contribution of internal variability to recent Arctic sea ice loss

Impacts of exposure to ambient temperature on burden of disease: a systematic review of epidemiological evidence [link]

“wicked problems require a range of difficult perspectives, which should not only be included in the agenda setting of science but also in the assessment of scientific products.”

Evaluating climate model simulations of the radiative forcing and radiative response at the Earth’s surface

Water Vapor, Clouds, and Saturation in the Tropical Tropopause Layer –

Risks of hydroclimatic regime shifts across the western United States [link]

Late Cretaceous extreme warmth at high southern latitudes [link]

An unexpected spike in methane emissions threatens to negate or reverse efforts to stave off climate change by reducing CO2 emissions.

“We show that the changing coverage of weather stations in the Indian rainfall data leads to spurious increases in extreme rainfall. This suggests that previously reported trends of extreme rainfall are biased positive.”

Annual variability of ice-nucleating particle concentrations at different Arctic locations (open access)

Volume, heat and freshwater divergences in the subpolar North Atlantic suggest the Nordic Seas as key to the state of the meridional overturning circulation

On the spectrum of variability in climate models [link]

Factors affecting interdecadal variability of air–sea CO2 fluxes in the tropical Pacific, revealed by an ocean physical–biogeochemical model [link]

Inter-annual variability of wind and solar electricity generation and capacity values in Texas (open access)

A large uptick in dust activity in northern Mesopotamia roughly 4,200 years ago coincided with the decline of the Akkadian Empire. [link]

Variable external forcing obscures the weak relationship between the NAO and North Atlantic multi-decadal SST variability

“Most models largely underestimate photosynthetic carbon fixation and therefore likely overestimate future atmospheric CO2 abundance and ensuing climate change, though not proportionately”. [link]

Extreme precipitation is increasing, so why aren’t ?

Atlantic Zonal Mode: An emerging source of Indian summer monsoon variability in a warming world

Introducing ‘(un)safe (un)certainty’ as a framework for climate adaptation. Embracing uncertainty: A discursive approach to understanding pathways for climate adaptation in Senegal.

Responses of soil carbon sequestration to climate smart agriculture practices: A meta‐analysis

Formation of snow cover anomalies over the Tibetan Plateau in cold seasons

The Indian Ocean’s gravity has a huge dent in it, and seismologists are trying to figure out why.

On the financial viability of negative emissions [link]

Material efficiency strategies to reducing greenhouse gas emissions associated with buildings, vehicles, and electronics—a review (open access)

A new study in Nature Climate Change finds an even stronger case for reducing CO2 emissions to stabilize climate change through a shift from coal to natural gas. Findings are robust under range of leakage rates and uncertainties in emissions data. [link]
