So far, available studies have mostly investigated the magnitude of erosional C transport and measurements of vertical C fluxes on the catchment or regional scale.

Electron microscopic picture of microfossils found in drill cores of sediments dating back 40 million years.

We present current knowledge on the role of erosional C distribution in controlling the stabilization and release of C in soils, taking into consideration the important geomorphic, ecological, hydrologic, pedologic and micro-climatic processes and controls that affect soil organic carbon (SOC) stock, fluxes, and persistence in dynamic landscapes.

Further, we provide an overview on latest experimental and modelling approaches that are being used to investigate the role of erosion in the carbon cycle.

By studying the remains of such marine plankton - and particularly compounds they produce called alkenones - scientists gain an accurate perspective of past climate change.

They found that the baseline CO2 levels in the broader Eocene period were around 1000 to 2000 parts per million (ppm).

During the temperature peaks atmospheric CO2 levels reached 4000 ppm or higher, backing the theory of the greenhouse gas cause.

Much multidisciplinary research focuses on reconstructing fossil environments using information from the fossil ocean floor.

    Mark Juergensmeyer, a former president of the American Academy of Religion, has argued that there has been a global rise in religious nationalism after the Cold War due to a post-colonial collapse of confidence in Western models of nationalism and the rise of globalization.

    On top of it all is the feminist-driven academic and journalistic culture celebrating that yesterday’s “loose” women are today’s “liberated” women, able to proudly “explore their sexuality” without “getting punished for their lust,” as the feminist writer Naomi Wolf put it in the to trying to remove the stigma from . Of course, if a man mistakes a woman being “sexual in any way she chooses” for consent to have sex, it’s still rape.
