Future Climate Projections

Climate change is the most important contemporary environmental problem that the world faces, yet it is the subject of many misconceptions. Climate science has been used for political ends and distorted in the press, both intentionally and through ignorance. This article presents an overview of what is known about global warming and what is controversial, about future climate projections and their impacts, and about the emissions responsible for climate change and policies to limit them.

Future Climate Projections

<p>Coarse resolution global climate models (GCM) cannot resolve fine-scale drivers of regional climate, which is the scale where climate adaptation decisions are made. Regional climate models (RCMs) generate high-resolution projections by dynamically downscaling GCM outputs. However, evidence of where and when downscaling provides new information about both the current climate (added value, AV) and projected climate change signals, relative to driving data, is lacking. Seasons and locations where CORDEX-Australasia ERA-Interim and GCM-driven RCMs show AV for mean and extreme precipitation and temperature are identified. A new concept is introduced, ‘realised added value’, that identifies where and when RCMs simultaneously add value in the present climate and project a different climate change signal, thus suggesting plausible improvements in future climate projections by RCMs. ERA-Interim-driven RCMs add value to the simulation of summer-time mean precipitation, especially over northern and eastern Australia. GCM-driven RCMs show AV for precipitation over complex orography in south-eastern Australia during winter and widespread AV for mean and extreme minimum temperature during both seasons, especially over coastal and high-altitude areas. RCM projections of decreased winter rainfall over the Australian Alps and decreased summer rainfall over northern Australia are collocated with notable realised added value. Realised added value averaged across models, variables, seasons and statistics is evident across the majority of Australia and shows where plausible improvements in future climate projections are conferred by RCMs. This assessment of varying RCM capabilities to provide realised added value to GCM projections can be applied globally to inform climate adaptation and model development.</p>

Human consumption of livestock remains a marginal issue in climate change debates, partly due to the IPCC's arbitrary adoption of 100-year global warming potential framework to compare different emissions, blinding us to the significance of shorter-term emissions, namely methane. Together with the gas it reacts to form - tropospheric ozone - methane has been responsible for 37% of global warming since 1750, yet its atmospheric life is just 10 years. Neglecting its role means overlooking powerful mitigation opportunities. The chapter discusses the role of livestock, the largest anthropogenic methane source, and the need to include reduced meat consumption in climate change responses. Looking beyond the conventional focus on the consumer, we point to some underlying challenges in addressing the meat-climate relationship, including the climate science community's reluctance to adopt a short-term focus in its climate projections. Policy options are presented.

Abstract. Sublimation of snow is an important factor of the hydrological cycle in Mongolia and is likely to increase according to future climate projections. In this study the hydrological model TRAIN was used to assess spatially distributed current and future sublimation rates based on interpolated daily data of precipitation, air temperature, air humidity, wind speed and solar radiation. An automated procedure for the interpolation of the input data is provided. Depending on the meteorological parameter and the data availability for the individual days, the most appropriate interpolation method is chosen automatically from inverse distance weighting, Ordinary Least Squares interpolation, Ordinary or Universal Kriging. Depending on elevation simulated annual sublimation in the period 1986–2006 was 23 to 35 mm, i.e. approximately 80% of total snowfall. Moreover, future climate projections for 2071–2100 of ECHAM5 and HadCM3, based on the A1B emission scenario of the Intergovernmental Panel on Climate Change, were analysed with TRAIN. In the case of ECHAM5 simulated sublimation increases by up to 17% (26...41 mm) while it remains at the same level for HadCM3 (24...34 mm). The differences are mainly due to a distinct increase in winter precipitation for ECHAM5. Simulated changes of the all-season hydrological conditions, e.g. the sublimation-to-precipitation ratio, were ambiguous due to diverse precipitation patterns derived by the global circulation models.

Carbon Economy

Global warming is the top ten environmental problem of the world, and the greenhouse effect caused by a large number of CO2 emissions from human society is the root of climate change. Currently, the global warming becomes serious and has become the crisis and challenge of all the world. Low carbon economy is the best mode of coping with the global warming and realizing sustainable development of economy and society. In many policies to promote low carbon economic development, various related carbon tax policies and regulations are still the most dependent means of every country. The carbon tax levied by part of OECD countries is worthy of our reference.

Climate change is a global phenomenon; its outcome affects societies around the world. Due to the systemic effects of climate change, Pakistan frequently suffers from natural disasters. The present study explored the press coverage and framing trends about three climate issues (1) Climate change and global warming (2) climate change and water scarcity (3) agriculture and food security. The study was based on content analysis. In this research, editorials of four newspapers; The Nation, The News, Nawa-i-Waqt and Jang were examined during 2011 to 2018. It was census study and all editorials were examined during the period of 8 years. The results showed that all four newspapers highly covered issues of water scarcity in Pakistan and however, gave less coverage to the issue of agriculture and food security. Thus, overall editorial coverages increase with every passing year and mainstream Pakistani press framing trends were remain very positive and suggestive.
