Greenhouse climate model : an aid to estimate the influence of supplemental lighting on greenhouse climate
GeoGreenhouse project involves the construction of a greenhouse for growing tomatoes in Iceland. The first stage consists of a gross area of five hectares. Due to the peculiarities of such project and because of the unique weather, a greenhouse climate model is advisable to analyze various design …

Marine carbonate accumulation during the greenhouse climate of the Eocene
… (CIEs) in the sedimentary record. The hothouse climate of early Eocene transitioned to a relatively cooler and less explored ‘warmhouse’ regime during middle-late Eocene, when multiple transient warming events occurred, which were at times associated with significant fluctuations in the oceanic …

Carbonate Carbon Isotope Chemostratigraphy from the Ruby Ranch Member of the Cedar Mountain Formation in the Western San Rafael Swell
… with a late Aptian “cold snap” in an otherwise greenhouse climate. This data produced values that were not reliable estimates of temperature. Additional studies are needed to confirm a temperature change over the C10 positive isotope excursion and refine the paleoclimate record at this location.

The Aptian-Albian ironstone of the Rapid Creek formation, Little Fish Creek, NWT: implications for Cretaceous Ocean Anoxic Events and critical mineral deposits
… Arctic Large Igneous Province (HALIP) under a greenhouse climate may have been important for producing anoxic seawater enriched in Fe and Mn to the Blow Trough. Such an interpretation implies that the Aptian-Albian Oceanic Anoxic Event (OAE) 1b may have been regional rather than global in …

THE CLIMATIC, BIOTIC AND TECTONIC EVOLUTION OF THE PALEOGENE RENOVA FORMATION OF SOUTHWESTERN MONTANA
… an important record of Paleogene floral, faunal, climate and tectonic change in the northern Rocky Mountains. The period between the end of the early Eocene and the early Oligocene (~49-32 Ma) was a time of rapid and far-reaching climate change. This period saw the end of global greenhouse climate …

Response of semi-permanent prairie wetland to climate change: a spatial simulation model
… 11-year simulation was run using a normal versus greenhouse climate. Although water level fluctuations still occurred, peak values were significantly lower in the warming scenario and the wetland dried in most years. Simulations also revealed a significant change in the vegetation, from a nearly …

Late Jurassic to Early Cretaceous stable isotope and geochemical records from the northern high latitudes: implications for palaeoclimate
… are widely accepted as being dominated by greenhouse conditions with elevated CO2 levels and warm polar regions. Although much compelling evidence to support this idea of global warmth exists, some recent studies propose that the greenhouse climate may at times have been punctuated by …

Developing iodine proxies for oceanic oxygenation conditions during greenhouse episodes
… because of the complex feedbacks in the climate-ocean-biota system. Global warming lowers the solubility of oxygen in the ocean and drives an enhanced hydrological cycle with increased nutrient delivery to the oceans, leading to increases in organic production, the degradation of which …

Probabilistic source-to-sink analysis of the provenance of the California paleoriver: implications for the early Eocene paleogeography of western North America
… events of given magnitude are similar across climates and hydrological regimes. These scaling relationships between 99th percentile and higher magnitudes of flow and catchment area have greatly improved predictive precision compared to existing relationships using average discharge. The …

Orbital-scale fluctuations in continental weathering flux and continental ice-volume during greenhouse and icehouse climate intervals : evidence from oxygen and neodymium isotopes
Rapid changes in global and local climate and weather, noticeable over our lifetimes, have spurred heated public and political debate over the cause of these climatic changes, whether or not we can reverse, stop or slow down this process, and how to create adequate models that can predict Earth's …
