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 …
Reconstructions of the vegetation of Europe during the Last Glacial Maximum (LGM) are an enigma. Pollen-based analyses have suggested that Europe was largely covered by steppe and tundra, and forests persisted only in small refugia. Climate-vegetation model simulations on the other hand have consistently suggested that broad areas of Europe …
The Pacific Island Climate Outlook Forum (PICOF) has issued its Regional climate outlook and tropical cyclone outlook for 2016/2017. The forum, which took place on 17th and 18th of October in Nadi, Fiji, had a specific focus on the impacts of the 2015/16 El Niño. Highlights of the outlook were: …
Anthropogenic aerosols are a key factor governing Earth’s climate, and play a central role in human-caused climate change. However, because of aerosols’ complex physical, optical, and dynamical properties, aerosols are one of the most uncertain aspects of climate modeling. Fortunately, aerosol measurement networks over the past few decades have led …
The 2015 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 2015 bring? How different was 2015?; and provides regional analysis on Africa, the Americas, Asia, Europe, and Oceania. It reports that 376 …
This paper estimates the causal eff ect of increased ambient air pollution on the frequency of road traffic accidents in the United Kingdom between 2009 and 2014. An instrumental variable approach is applied, exploiting atmospheric temperature inversions as a source of plausibly exogenous variation in daily air pollution levels. The …
June marks 14 consecutive months of record heat for the globe. Average sea surface temperature was also record high, Persistent heat on land and in the sea this June shattered records, yet again. June 2016 was 1.62 degrees F above the 20th century average, breaking last year’s record for the …
Humans affect fire regimes by providing ignition sources in some cases, suppressing wildfires in others, and altering natural vegetation in ways that may either promote or limit fire. In North America, several studies have evaluated the effects of society on fire activity; however, most studies have been regional or subcontinental …
Tropopause temperatures (TPTs) control the amount of stratospheric water vapour, which influences chemistry, radiation and circulation in the stratosphere, and is also an important driver of surface climate. Decadal variability and long-term trends in tropical TPTs as well as stratospheric water vapour are largely unknown. Here, we present for the …
High precipitation quantiles tend to rise with air temperature, following the so-called Clausius–Clapeyron scaling. This CC-scaling relation breaks down, or even reverts, for very high temperatures. In our study, we verify this reversal using a 60-year period of summer data in Germany. One of the suggested meteorological explanations is limited …
Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally, around half of cloud condensation nuclei originate from nucleation of atmospheric vapours. It is thought that sulfuric acid is essential to initiate most particle formation in …
Despite documented intra-urban heterogeneity in the urban heat island (UHI) effect, little is known about spatial or temporal variability in plant response to the UHI. Using an automated temperature sensor network in conjunction with Landsat-derived remotely sensed estimates of start/end of the growing season, we investigate the impacts of the …
We have addressed the question of whether the massive deficit of 42% in rainfall over the Indian region in June 2014 can be attributed primarily to the El Niño. We have shown that the variation of convection over the Northern part of the Tropical West Pacific (NWTP: 120–150E, 20–30N) plays …
The year 2015 will stand out in the historical record of the global climate in many ways. Modern records for heat were broken: 2015 was a record warm year both globally and in many individual countries. Heatwaves were extremely intense in various part of the world, leading to thousands of …
The 2016 World Energy Issues Monitor: A climate of innovation – responding to the commodity price storm, samples the views of CEOs, Ministers and experts from across the globe to highlight the critical uncertainties facing the sector. The aim of this report is to ensure that energy leaders across the …
European air quality legislation has reduced emissions of air pollutants across Europe since the 1970s, affecting air quality, human health and regional climate. We used a coupled composition-climate model to simulate the impacts of European air quality legislation and technology measures implemented between 1970 and 2010. We contrast simulations using …
As the world’s fastest spreading vector-borne disease, dengue was estimated to infect more than 390 million people in 2010, a 30-fold increase in the past half century. Although considered to be a non-endemic country, mainland China had 55,114 reported dengue cases from 2005 to 2014, of which 47,056 occurred in …
The Amazon basin is a vast continental area in which atmospheric composition is relatively unaffected by anthropogenic aerosol particles. Understanding the properties of the natural biogenic aerosol particles over the Amazon rainforest is key to understanding their influence on regional and global climate. While there have been a number of …
The effects of type 1 and type 2 diabetes on the body's physiological response to thermal stress is a relatively new topic in research. Diabetes tends to place individuals at greater risk for heat-related illness during heat waves and physical activity due to an impaired capacity to dissipate heat. Specifically, …
The El Niño weather phenomenon is expected to be the fiercest in 18 years at the start of 2016 and threatens to adversely affect crop and livestock production prospects in Southern Africa, according to the Food and Agriculture Organization (FAO) of the United Nations. A reduced agricultural output would follow …
