Atmospheric pCO2 reconstructed across five early Eocene global warming events

Decline of coral reefs during late Paleocene to early Eocene global warming

Atmospheric hypotheses’ of Earth’s global warming

Two hypotheses are presented, outlining a new cause for global warming. We propose that the crucial factor in global warming is the amount and position of water vapour through the atmosphere. The purpose of this report is to open the debate and to encourage discussion among scientists. When analyzing the mean-year trend of the Earth’s surface temperature for the past 140 years (see for Fig. 1(a...

global warming and atmospheric thickness of the lower half

most scientists believe that the phenomenon of global warming occurred, however, in the case of the occurrence of this phenomenon by some environmental scientists have raised doubts. they are questioning global warming by arguing that the temperature recorded at the weather stations cannot be representative of the occurrence of the temperature rise. because with the passage of time and the incr...

Global carbon cycle perturbation across the Eocene-Oligocene climate transition

The Eocene-Oligocene transition (EOT), ~34Ma, marks a tipping point in the long-term Cenozoic greenhouse to icehouse climate transition. Paleorecords reveal stepwise rapid cooling and ice growth across the EOT tightly coupled to a transient benthic δC excursion and a major and permanent deepening of the carbonate compensation depth (CCD). Based on biogeochemical box modeling, Merico et al. (200...

Simulation of early 20th century global warming

The observed global warming of the past century occurred primarily in two distinct 20-year periods, from 1925 to 1944 and from 1978 to the present. Although the latter warming is often attributed to a human-induced increase of greenhouse gases, causes of the earlier warming are less clear because this period precedes the time of strongest increases in human-induced greenhouse gas (radiative) fo...
