Technology policy lies at the core of the climate change challenge. Even with a cutback in wasteful energy spending, our current technologies cannot support both a decline in carbon dioxide emissions and an expanding global economy. If we try to restrain emissions without a fundamentally new set of technologies, we will end up stifl ing economic growth, including the development prospects for b...

The ability to directly remove carbon dioxide from the atmosphere allows the decoupling of emissions and emissions control in space and time. We ask the question whether this unique feature of carbon dioxide removal technologies fundamentally alters the dynamics of climate mitigation pathways. The analysis is performed in the coupled energyeconomy-climate model ReMIND using the bioenergy with C...

The concentration of carbon dioxide in the atmosphere has reached a record level — increasing by 0.6 per cent last year alone — and methane levels are rising for the first time in a decade according to new results, renewing fears about global climate change prospects. Researchers at the Mauna Loa observatory in Hawaii say that carbon dioxide levels in the atmosphere are now at 387 parts per mil...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

The decoupling of fossil-fueled electricity production from atmospheric carbon dioxide emissions via CO2 capture and sequestration (CCS) is increasingly regarded as an important means of mitigating climate change at a reasonable cost. Engineering analyses of CO2 mitigation typically compare the cost of electricity for a base generation technology to that from a similar plant with CO2 capture an...

Land-use change accounted for 18% of global greenhouse gas emissions in 2000, making it the second largest source of emissions, after the power sector. These emissions arise from a change in the management of land by humans, such as conversion of forests to pasture land. The following sections will explain the role of the land, that is plants and soils, in the natural carbon cycle, and how chan...

ABSTRACT: The aim of this study is to measure the in-situ carbon dioxide emissions from forest floors in forested and deforested areas in Karasu Forests in Western Black Sea Region of Turkey. Carbon dioxide emissions from forest floors are one of the main reasons of increasing the carbon concentration in the atmosphere. Deforestation, releases CO2 to the atmosphere because carbon stored in the ...

Direct air capture is regarded as a plausible alternate approach that, if economically practical, can mitigate the increasing carbon dioxide emissions associated with two of the main carbon polluting sources, namely stationary power plants and transportation. Here we show that metal-organic framework crystal chemistry permits the construction of an isostructural metal-organic framework (SIFSIX-...
