This paper discusses the technology of direct capture of carbon dioxide from the atmosphere called air capture. It develops a simple arithmetic description of the magnitude of the challenge of stabilizing atmospheric concentrations of carbon dioxide as a cumulative allocation over the 21st century. This approach, consistent with and based on the work of the Intergovernmental Panel on Climate Ch...

Interagency Committee relies on Department of Commerce and NOAA certifications regarding compliance with Section 515 and Department guidelines as the basis for determining that this product conforms with Section 515. For purposes of compliance with Section 515, this CCSP Synthesis and Assessment Product is an " interpreted product " as that term is used in NOAA guidelines and is classified as "...

According to the Intergovernmental Panel on Climate Change (IPCC, 2007), global climate change, which will lead to a temperature increase of the lower atmosphere, can be traced to an increased concentration of carbon dioxide (CO2) and other infrared-active gases. Urban agglomerations are particularly affected because, in contrast to the surrounding rural areas, they are characterised by a high ...

We analyse global temperature and sea-level data for the past few decades and compare them to projections published in the third and fourth assessment reports of the Intergovernmental Panel on Climate Change (IPCC). The results show that global temperature continues to increase in good agreement with the best estimates of the IPCC, especially if we account for the effects of short-term variabil...

Crop quality is directly related to national food security and people’s living standards, it also key the improvement of agricultural efficiency. According Fifth Assessment Report Intergovernmental Panel on Climate Change (IPCC), climate change has already exerted a negative impact crop quality. To address scientifically, this paper reviews latest progress in studies quality, points out limitat...

The Ganges-Brahmaputra-Meghna delta is vulnerable to sea level rise from global warming. Based on predictions for the year 2100 given in 6th Assessment Report by Intergovernmental Panel Climate Change (IPCC), we examine effect of uncertainty maximum tidal elevation statistics at several locations along Bangladesh coastline using a discretized derived distribution approach. For five IPCC scenari...

Scenarios of global greenhouse gas emissions have played a key role in climate change analysis for over twenty years. Currently, several research communities are organizing to undertake a new round of scenario development in the lead-up to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). To help inform this process, we assess a number of past efforts to devel...

The release of new and updated sea-level rise (SLR) information, such as from the Intergovernmental Panel on Climate Change (IPCC) Assessment Reports, needs to be better anticipated in coastal risk adaptation assessments. This requires assessments regularly reviewed needed, reflecting information but retaining useful earlier In this paper, guidance types SLR available is presented, including fo...
