Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, according to this new report by the World Meteorological Organisation (WMO). This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface …
February 2016 was the most anomalously warm month — 2.43° Fahrenheit (1.35° Celsius) warmer than the average from 1951 to 1980 — in 135 years of record keeping, according to NASA. February record warm February 2016 was the warmest February on record by a substantial margin as well — 0.8° …
A manipulative experiment in which a reef is alkalinized in situ shows that calcification rates are likely to be lower already than they were in pre-industrial times because of acidification.
Global temperatures in February smashed previous monthly records by an unprecedented amount, according to Nasa data, sparking warnings of a climate emergency. The result was “a true shocker, and yet another reminder of the incessant long-term rise in global temperature resulting from human-produced greenhouse gases”, wrote Jeff Masters and Bob …
The level of carbon dioxide in the atmosphere increased at a record pace last year, US government scientists reported, raising new concern about one of the top greenhouse gases and the effects of global warming. The measurement came from the National Oceanic and Atmospheric Administration's Mauna Loa Observatory in Hawaii. …
This year is shaping up to be possibly the hottest in human history after satellite readings showed how February obliterated the temperature record set in January. The record comes as a new study warns that the rate of warming around the globe is faster than previously predicted with dire consequences …
The terrestrial biosphere can release or absorb the greenhouse gases, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), and therefore has an important role in regulating atmospheric composition and climate. Anthropogenic activities such as land-use change, agriculture and waste management have altered terrestrial biogenic greenhouse gas fluxes, and the …
Japan's weather bureau said on Thursday the El Nino weather pattern, which is often linked to heavy rainfall and droughts, was expected to continue weakening and that there was a high possibility the weather would return to normal by summer. The Japan Meteorological Agency projected a similar forecast last month. …
This paper discusses the scope for market mechanisms, already established for greenhouse gas mitigation in Annex 1 countries that ratified the Kyoto Protocol, for implementing "net mitigation," defined here as mitigation beyond Annex 1 countries' formal mitigation requirements under the Kyoto Protocol. Such market mechanisms could be useful for establishing …
This study investigated impacts of urban forms on the future thermal environment over Beijing, the capital city of China. Beijing is experiencing remarkable urban expansion and is planned to undergo the transformation of urban forms from single-centric (compact-city)to poly-centric city (dispersedcity). Impacts of urban forms on the future thermal environment …
A delay in the onset of the La Nina weather pattern this year is likely to buoy crops across key growing regions in the United States, Australia and India, a leading weather forecaster said on Thursday. Another year of bumper production of crops such as corn, wheat and soybeans would …
Chronic nitrogen deposition has measureable impacts on soil and plant health. We investigate burning emissions from biomass grown in areas of high and low NO x deposition. Gas and aerosol-phase emissions were measured as a function of photochemical aging in an environmental chamber at UC-Riverside. Though aerosol chemical speciation was …
The World Climate Research Programme (WCRP) Climate and Cryosphere (CliC) Project, the Arctic Monitoring and Assessment Programme (AMAP) and the International Arctic Science Committee (IASC) have released a summary report, titled 'The Arctic Freshwater System in a Changing Climate,' which outlines the effects of the changing Arctic atmosphere on the …
This Compendium of Environment Statistics 2015 published by the Ministry of Statistics and Programme Implementation is the sixteenth edition of its series and covers five core parameters - biodiversity, atmosphere, land/soil, water and human settlements.
With the mercury topping 36.5 degrees Celsius on Saturday, Karachi witnessed it the hottest day of the month in over two decades, the Met office said on Sunday. The heat wave is expected to continue till Monday or Tuesday after which temperatures will gradually dwindle down, officials say. The reason …
The El Niño–Southern Oscillation (ENSO) affects the tropospheric concentrations of many trace gases. Here we investigate the ENSO influence on mercury concentrations measured in the upper troposphere during Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container flights and at ground at Cape Point, South …
There is a high sediment mercury levels in Artic which is more prone for pollution in the region, a recent study has revealed. The study was conducted on 'Kongsfjorden', one of the Fjord located at Ny-Alesund, Svalbard, by a group of researchers from Kottayam Kerala' School of Environmental Sciences affiliated …
After two straight years of drought, there's finally reason to hope for a normal monsoon this year. Most international models indicate that El Nino, the scourge of the monsoon in India, would dissipate by summer, providing neutral conditions for the rainy season in the country. Although it is early days …
The past month is the warmest since record keeping began in 1880, which continues a nine-month streak of record high monthly temperatures, according to the latest report released by the U.S. National Oceanic and Atmospheric Administration (NOAA). The average temperature across global land and ocean surfaces in January was 1.04 …
The El Niño that caused record temperatures, drought and floods over the last year has passed its peak strength but will continue to have humanitarian impacts for months to come, the UN has said. The World Meteorological Organisation (WMO) said the event, which plays havoc with weather systems around the …
Last month was the hottest January in modern times, US data showed on Wednesday, the latest in a string of heat records fuelling concerns over the pace of climate change. The average temperature across global land and ocean surfaces was 1.87 degrees Fahrenheit (1.04 Celsius) above the 20th century average …
