Claimed human-caused warming of the Earth to dangerous and unprecedented levels by human-related emissions of carbon dioxide is contradicted mainly by a non-correlation of carbon dioxide levels with warming. Details are given of misleading proxy temperature reconstructions, as well as of misleading proxy atmospheric carbon dioxide concentrations. Evidence is presented to show that trepidation a...

Desertification, a natural process, is exacerbated by anthropogenic activities. It reduces soil productivity, jeopardizes food security, impairs environment quality, accelerates global warming and exacerbates global security risks. Degradation of soil and vegetation aggravates the emission of greenhouse gases into the atmosphere. The biophysical processes of soil and vegetation degradation are ...

Climate Change has emerged as one of the grand global challenges facing humanity. The dominant anthropogenic greenhouse gas that seems to be contributing to the climate change problem, carbon dioxide (CO2), has a complex cycle through the atmosphere, oceans and biosphere. The combustion of fossil fuels (power production, transportation, etc.) remains the largest source of anthropogenic CO2 to t...

In the analysis of environmental conditions and impacts, the viewpoint that greenhouse gases, primarily anthropogenic (industrial, human) carbon dioxide, play a determining role in the change of global temperatures, ( the increase experienced in the last one and a half decade), has been given widespread publicity recently. Coal-fired power plants are the first to blame for the increase in atmos...

We derive a constraint on the strength of CO2 fertilisation of the terrestrial biosphere through a “top-down” approach, calibrating Earth system model parameters constrained by the post-industrial increase of atmospheric CO2 concentration. We derive a probabilistic prediction for the globally averaged strength of CO2 fertilisation in nature, for the period 1850 to 2000 AD, implicitly net of oth...

[1] Isoprenoids (isoprene and monoterpenes) are the most dominant class of biogenic volatile organic compounds (BVOCs) and have been shown to significantly affect global tropospheric chemistry and composition, climate, and the global carbon cycle. In this study we assess the sensitivity of biogenic isoprene and monoterpene emissions to combined and isolated fluctuations in observed global clima...

Th e risk of adverse climate change from global warming forced in part by growing greenhouse gas emissions is serious. While projections vary, there is now wide acceptance among the scientifi c community that global warming is occurring, that the human contribution is important, and that the eff ects may impose signifi cant costs on the world economy. As a result, governments are likely to adop...

Although the transport sector is responsible for a large and growing share of global emissions affecting climate, its overall contribution has not been quantified. We provide a comprehensive analysis of radiative forcing from the road transport, shipping, aviation, and rail subsectors, using both past- and forward-looking perspectives. We find that, since preindustrial times, transport has cont...

Accurate estimates of global carbon emissions are critical for understanding global warming. This paper estimates net carbon emissions from land use change in Bolivia during the periods 1990-2000 and 2000-2010 using a model that takes into account deforestation, forest degradation, forest regrowth, gradual carbon decomposition and accumulation, as well as heterogeneity in both above ground and ...
