The report discusses the climate condition over Indian region during the year 2023. Notably, global temperatures soared to exceptionally high levels during this period (WMO.No.1347). The India Meteorological Department continuously monitors weather and climate over Indian region. The annual mean land surface air temperature averaged over India during 2023 was …
Using current climate models, regional-scale changes for Florida over the next 100 years are predicted to include warming over terrestrial areas and very likely increases in the number of high temperature extremes. No uniform definition of a heat wave exists. Most past research on heat waves has focused on evaluating …
The Arctic Monitoring and Assessment Programme (AMAP), one of the six Working Groups of the Arctic Council, has released its assessment report on black carbon and ozone as Arctic climate forcers, which complements an earlier report on methane as Arctic climate forcer as part of AMAP's assessment on short-lived climate …
The long-term rise in global temperatures, the dominant cause of which is the anthropogenic emission of greenhouse gases, combined with the effects of a developing El Niño, have resulted in unusual global warmth in 2015. The global-average near-surface temperature for 2015 is likely to be the warmest on record according …
Urban populations are highly vulnerable to the adverse effects of heat, with heat-related mortality showing intra-urban variations that are likely due to differences in urban characteristics and socioeconomic status. The objective was to investigate the influence of urban green and urban blue, i.e., urban vegetation and water bodies, on heat-related …
Heat waves are the most significant cause of mortality in the US compared to other natural hazards. Prior studies have found increased heat exposure for individuals of lower socioeconomic status in several US cities, but few comparative analyses of the social distribution of urban heat have been conducted. To address …
The observation of high aerosol hygroscopic growth in Madrid is mainly limited to specific atmospheric conditions, such as local stagnation episodes, which take place in winter time. One of these episodes was identified in December 2014 and the hygroscopic growth factor (GF) measurements obtained in such episode were analysed in …
The Arctic Monitoring and Assessment Programme (AMAP), one of the six Working Groups of the Arctic Council, has released its assessment report on methane as a climate forcer. The report concludes that methane mitigation can complement action on carbon dioxide (CO2) mitigation in reducing Arctic warming, and contribute to reducing …
GCOS has released its report Status of the Global Observing System for Climate (GCOS-195) which has been submitted to the UNFCCC in December in Paris. The results of the global observing system have proved invaluable and have underpinned the IPCC fifth assessment report. However, as the IPCC identifies, there are …
This paper presents a method for attributing regional trends in the frequency of extremely hot days (EHDs) to changes in the frequency of the atmospheric patterns that characterize such extraordinary events. The study is applied to mainland Spain and the Balearic Islands for the extended summers of the period 1958–2008, …
A study was taken up to identify annual changes in temperature. For this study, daily (maximum and minimum) temperature data for 45 years (1969–2013) prepared by the India Meteorological Department, Pune were used. The identification of change was based on statistical trend analysis. From the analysis, it can be concluded …
Pollen analysis of 1.75 m deep sediment core from Tula-Jalda (Amarkantak) in Anuppur district, Madhya Pradesh shows that around 4500–3600 cal years BP, this region supported open mixed tropical deciduous forests comprising chiefly Madhuca indica followed by Terminalia, Mitragyna parvifolia, Haldina cordifolia, Emblica officinalis and Acacia, under a warm and …
The 2014 annual review of disaster figures based on the EM-DAT database outlines information about the EM-DAT International Disaster Database, its definitions, criteria and content; asks: What did 2014 bring? How different was 2014?; and provides regional analysis on Africa, the Americas, Asia, Europe, and Oceania. It reports that 324 …
Invasive species are among the primary threats to biodiversity and risk assessment is one problem-solving approach that can prioritize and guide efforts to reduce the negative consequences of invasion. We used a nichemodeling framework to conduct a geographic risk assessment of exotic reptiles in the state of Florida, USA, a …
Pakistan is among the lowest emitters of greenhouse gases in the world, but ranks among the highest in terms of vulnerability to climate change. Its high dependency on the Indus River system makes it particularly vulnerable to the increasing rate of glacial melt and erratic monsoon patterns. The 2010 floods …
The researchers combined Landsat and MODIS data in a land model to assess the impact of urbanization on US surface climate. For cities built within forests, daytime urban land surface temperature (LST) is much higher than that of vegetated lands. For example, in Washington DC and Atlanta, daytime mean temperature …
Secondary organic aerosol (SOA) affects the earth’s radiation balance and global climate. High-elevation areas are sensitive to global climate change. However, at present, SOA origins and seasonal variations are understudied in remote high-elevation areas. Original Source
In a report titled 'State of the Climate in 2014,' the American Meteorological Society has described 2014 as the warmest year on record. The World Meteorological Organization (WMO) has also reported that the January-June 2015 period was the hottest on record, citing figures provided by the National Atmospheric and Oceanic …
The sensitivity of mosquito vector and dengue virus biology to diurnal temperature variability has been established, but this study is the first analyzing these relations with dengue occurrence. We show that Dhaka’s tropical hot monsoon climate and small variation in daily temperature enhance dengue transmission one month later. Large-scale climatic …
A limited literature base suggests that ambient temperature contributes to suicide, with studies typically focused on a single nation using temporal and spatial aggregated data. The researchers evaluated an association between ambient temperature and suicide in multiple cities in three East Asian countries.
With El Nino’ s return , the farmers and policy makers in Asia are bracing for prolonged droughts and crop destruction that would push up food prices in the region says this IMF working paper This paper employs a dynamic multi-country framework to analyze the international macroeconomic transmission of El …
