A Closer Earth and the Faint Young Sun Paradox: Modification of the Laws of Gravitation or Sun/Earth Mass Losses? [PDF]

open access: yesGalaxies, 2013
Given a solar luminosity LAr = 0.75L0 at the beginning of the Archean 3.8 Ga ago, where L0 is the present-day one, if the heliocentric distance, r, of the Earth was rAr = 0.956r0, the solar irradiance would have been as large as IAr = 0.82I0.

Present climate of lake Montcortès (Central Pyrenees): paleoclimatic relevance and insights on future warming

open access: yesCuadernos de Investigación Geográfica, 2022
The varved sediments of the Pyrenean Lake Montcortès (Pallars Sobirà, Lleida) embody a unique continuous high-resolution (annual) paleoarchive of the last 3000 years for the circum-Mediterranean region.

Global‐Krigger: A Global Kriging Interpolation Toolbox With Paleoclimatology Examples

open access: yesGeochemistry Geophysics Geosystems, 2023
Many applications in Earth sciences require spatial prediction, that is, obtaining a continuous scalar field from a set of discrete scalar data points on the Earth's surface.

CuticleTrace: A toolkit for capturing cell outlines from leaf cuticle with implications for paleoecology and paleoclimatology

open access: yesbioRxiv, 2023
Premise Leaf epidermal cell morphology is closely tied to plants’ evolutionary histories and growth environments, and is therefore of interest to many plant biologists. However, cell measurement can be time-consuming and restrictive with current methods.

Growing season thermal climate reconstructed at six pine stands in northern Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1994
At the northern coniferous timberline of the boreal region, growing season temperature is generally the major environmental factor limiting the growth processes of Scots pine (Pinus sylvestris L.). Variations in annual ring-widths of pines can be related

Editorial: Integration of records and simulations in paleoclimatology

open access: yesFrontiers in Earth Science, 2023
The past is the key to the future. Derived from natural records and model simulations, paleoclimate evidence extends instrument-based observations of Earth’s climate changes on inner-annual to glacial-interglacial time scales. This provides the long-term

A Study on Possible Solar Influence on the Climate of the Southern Hemisphere

open access: yesAtmosphere, 2022
Three multi-proxy reconstructions of temperature in the Southern Hemisphere, were analyzed over the last millennium. Fourier and wavelet analysis showed that century-scale (55–120 years) and bicentennial (ca 250 years) variability is present in this ...
