اواسط شهریور 1401 و در نزدیکی ساحل ماسه‌ای رودخانۀ نکا شمال ایران، به روش تورزدن روی گل‌آذین بوته‌های کاهوک (.Lactuca serriola L) میان تمشک وحشی (.Rubus idaeus انار (.Punica granatum L)، نمونه‌ای جیرجیرک جمع‌آوری شد که بررسی توسط کلیدهای شناسایی شکل‌شناسی مقایسه با نمونه‌های از قبل تعیین نام شدۀ موزۀ حشرات هایک میرزایانس رکورد جدید جنس گونه را تایید کرد. این اولین گزارش گونۀ Arachnocephalus ves...

Accurate estimation of methane (CH4) emission (ME) from enteric fermentation in China is essential to establishing and maintaining a reliable global ME inventory and developing strategies to mitigate such emissions. Based on modern animal production statistics, i.e., feed quality and quantity data for different feeding systems, enteric methane emissions (EME) in China during the period of 1990 ...

A guide to facts and fictions about climate change It has become fashionable in some parts of the UK media to portray the scientific evidence that has been collected about climate change and the impact of greenhouse gas emissions from human activities as an exaggeration. Some articles have claimed that scientists are ignoring uncertainties in our understanding of the climate and the factors tha...

Research Institute of Electric Power Industry jointly with National Center for Atmospheric Research. To contribute to the IPCC Fourth Assessment Report, multi-century global warming projections based on the IPCC SRES scenarios were conducted using the Earth Simulator. One of the features of our experiments is multi-century long-term projections under the stabilized radiative forcings of greenho...

www.thelancet.com Vol 383 April 5, 2014 1185 The Intergovernmental Panel on Climate Change (IPCC) released its latest report on March 31, 2014. This report was the second instalment of the Fifth Assessment Report, prepared by Working Group 2, on impacts, vulnerability, and adaptation to climate change. In this Comment, we, as contributors to the chapter on human health, explain how the IPCC rep...

associated with global climate change (e.g. Lambeck et al. 2002; Miller et al. 2005; IPCC 2001; IPCC 2007; Hansen et al. 2007; Broecker and Kunzig 2008). For example, during the last interglacial warm period (~125,000 yrs BP) sea level was approximately 5 m higher than present, and during the Last Glacial Maximum (~21,000 yrs BP), sea level was about 120 m lower than present (Figure 1) (Fairban...

1.Climate assessments like the IPCC have to date been written through a process in which IPCC-selected authors are given significant authority over the text, including judging their own work against work of their critics. This has led to biased information in the assessments and thus raises questions about a catastrophic view of climate change because the full range of evidence is not represent...

New calculations of the radiative forcing (RF) are presented for the three main well‐mixed greenhouse gases, methane, nitrous oxide, and carbon dioxide. Methane’s RF is particularly impacted because of the inclusion of the shortwave forcing; the 1750–2011 RF is about 25% higher (increasing from 0.48Wm to 0.61Wm) compared to the value in the Intergovernmental Panel on Climate Change (IPCC) 2013 ...
