TL;DR: In this paper, a comparative study comprising three transition metal oxides, MoO3, WO3 and V2O5, acting as front p-type contacts for n-type crystalline silicon heterojunction solar cells was performed.

TL;DR: Palaeoclimate reconstructions indicate that the transition occurred either as a predominantly abrupt shift towards the end of the LIA, or as a more gradual, continued decline over the past 150 years; this ambiguity probably arises from non-AMOC influences on the various proxies or from the different sensitivities of these proxies to individual components of the AMOC.

TL;DR: A yearly NAO reconstruction for the past millennium is presented, based on an initial selection of 48 annually resolved proxy records distributed around the Atlantic Ocean and built through an ensemble of multivariate regressions, and suggests that positive phases were dominant during the thirteenth and fourteenth centuries.

TL;DR: The United Nations Framework Convention on Climate Change (UNFCCC) process agreed in Paris to limit global surface temperature rise to “well below 2°C above pre-industrial levels. But what period is preindustrial? Somewhat remarkably, this is not defined within the UNFCCCs many agreements and protocols as mentioned in this paper.

TL;DR: The mid-1990s’ warming of the North Atlantic subpolar gyre was probably related to strengthened overturning as discussed by the authors, and observations and numerical models suggest that a climate reversal to a cooling trend occurred around 2005.
