TLDR
In this article, a detailed record of the Galapagos region over the last 135 thousand years (kyr) was reconstructed from G. ruber Mg/Ca from core TR163-22, which revealed a detailed (250-450 year resolution) climate history of the region.About:

Global temperature change.
TL;DR: Comparison of measured sea surface temperatures in the Western Pacific with paleoclimate data suggests that this critical ocean region is approximately as warm now as at the Holocene maximum and within ≈1°C of the maximum temperature of the past million years.

Target atmospheric CO2: Where should humanity aim?
James Hansen,Makiko Sato,Pushker Kharecha,David J. Beerling,Robert A. Berner,Valérie Masson-Delmotte,Mark Pagani,Maureen E. Raymo,Dana L. Royer,James C Zachos +9 more
TL;DR: In this paper, the authors show that the current CO2 level can be reduced to at most 350 ppm by phasing out coal use except where CO2 is captured and adopting agricultural and forestry practices that sequester carbon.

Holocene changes in eastern tropical Pacific climate inferred from a Galápagos lake sediment record

TL;DR: In this article, a new, continuous, climate record from El Junco Crater Lake in the Galapagos Islands reveals several abrupt changes in lake level and precipitation through the Holocene.
Journal ArticleDOI
A global perspective on Last Glacial maximum to Holocene climate change
TL;DR: In this article, 104 high-resolution paleoclimate records were used to characterize the timing and spatial pattern of climate change during the last deglaciation, suggesting the hemispheres were synchronized by greenhouse gases, local insolation and/or Northern Hemisphere induced ocean circulation changes.

TL;DR: The recent completion of drilling at Vostok station in East Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles.

Variations in the Earth's Orbit: Pacemaker of the Ice Ages
TL;DR: It is concluded that changes in the earth's orbital geometry are the fundamental cause of the succession of Quaternary ice ages and a model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next sevem thousand years is toward extensive Northern Hemisphere glaciation.

TL;DR: The recovery of a deep ice core from Dome C, Antarctica, that provides a climate record for the past 740,000 years is reported, suggesting that without human intervention, a climate similar to the present one would extend well into the future.

TL;DR: In this paper, the Wanninkhof dependence of the CO2 gas transfer velocity has been used to estimate the global ocean CO2 flux in the mean non-El Nino conditions for a reference year 1995.
