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 …
Super typhoon Soudelor, possibly the strongest storm of 2015, is powering towards Taiwan in the north-west Pacific after causing widespread damage in the Northern Mariana Islands. The category 5 storm is expected to strengthen further, with sustained wind speeds of 150 knots, or 277.8 km/h, later on Tuesday, US space …
An El Nino is now well established and continues to strengthen, the Australian Bureau of Meteorology (BOM) said, with models indicating that sea-surface temperature anomalies in the central Pacific Ocean are set to climb to the highest in 19 years. The El Nino, marked by a warming of sea-surface temperatures …
The anticipated rise in temperatures and frequency of heat waves in the country demands a comprehensive strategy to cope with this type of disastrous events in future. This report recommends the establishment of Heat-Health Warning System (HHWS) targeting the vulnerable segment of the urban centers. This warning system will have …
Warmer-than-usual water in parts of the Pacific Ocean indicates that a developing El Niño is intensifying and might become one of the strongest on record. And National Oceanic and Atmospheric Administration scientists think the weather phenomenon probably will continue through the winter of 2015-16, and into the spring of 2016. …
Parts of the Sydney region have shivered through another sub-zero morning with the city on track to record its chilliest July in 17 years in a month that is often marked by frequent cold fronts. The mercury dipped to minus 0.4 degrees in Richmond in Sydney's north-west on Tuesday morning, …
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 …
Relief of iron (Fe) limitation in the Southern Ocean during ice ages, with potentially increased carbon storage in the ocean, has been invoked as one driver of glacial–interglacial atmospheric CO2 cycles. Ice and marine sediment records demonstrate that atmospheric dust supply to the oceans increased by up to an order …
BEIJING, July 22 (Xinhuanet) -- The globally averaged temperature over land and ocean surfaces for January to June 2015, as well as for the month of June, was the hottest such period on record, WMO reported yesterday. The average temperature for the six-month period was 0.85°C above the 20th century …
Global temperature records continued to tumble in June, as the strengthening El Nino in the Pacific combined with background warming from climate change. Land and sea-surface temperatures last month and for the first half of 2015 were the warmest in 136 years of records, the US National Oceanic and Atmospheric …
The El Nino continues to strengthen in the Pacific, exceeding by at least one measure the monster event of 1997-98, according to the Bureau of Meteorology. All the key regions of the equatorial Pacific used to monitor El Ninos have recorded sea-surface temperatures of 1 degree above average for 10 …
Better forecasting is on the horizon thanks to the Bureau of Meteorology's new supercomputer. Tailored weather forecasting, including more detailed snapshots by suburb, is a step closer after the Bureau of Meteorology announced a $77 million supercomputer would arrive next year. To be housed in a "secret site" in Melbourne, …
A wide array of scientific disciplines and industries use radiocarbon analyses; for example, it is used in dating of archaeological specimens and in forensic identification of human and wildlife tissues, including traded ivory. Over the next century, fossil fuel emissions will produce a large amount of CO2 with no 14C …
Spatially extensive and persistent drought episodes have repeatedly influenced human history, including the 'Strange Parallels' drought event in monsoon Asia during the mid-18th century. Here we explore the dynamics of sustained monsoon failure using observed and tree-ring reconstructed drought patterns and a 1300-year pre-industrial community earth system model control run. …
Uptake of water by contrails in ice-supersaturated air and release of water after ice particle advection and sedimentation dehydrates the atmosphere at flight levels and redistributes humidity mainly to lower levels. The dehydration is investigated by coupling a plume-scale contrail model with a global aerosol–climate model. The contrail model simulates …
A device called 'Smart Citizen', that tracks elements of weather such as the amount of carbon dioxiode, nitrogen oxide, sound levels and humidity will soon be selling in Namibia. The device will cost N$2 000, courtesy of Fablab Namibia. The device is made in Barcelona, Spain. In an interview with …
Last month was the hottest June on record worldwide by a wide margin, Japan Meteorological Agency said, increasing the likelihood that 2015 will also be the warmest. Global surface temperatures were 0.41 degrees above the 1981-2010 average in June, the largest such anomaly in records going back to 1891, according …
Cutting levels of soot and other short-lived pollutants delivers tangible benefits and helps governments to build confidence that collective action on climate change is feasible. After the Paris climate meeting this December, actually reducing these pollutants will be essential to the credibility of the diplomatic process. (Opinion)
ABU DHABI // Masdar Institute scientists have come up with an accurate system to predict extreme weather. The “hydro-climate” model has also shown that the UAE’s weather has been getting hotter and drier, particularly in Abu Dhabi. Data collected shows climate extremes in the UAE, such as long periods without …
Scorching summers are likely to become common in the UK by the end of the century while winters turn wetter and less chilly, according to new research. Met Office researchers carried out a new analysis of long-range climate projections for the UK based on 30 year averages. It reveals that …
YESTERDAY was Shanghai’s coldest July day for 112 years, with the mercury topping out at just 21.2 degrees Celsius at the benchmark Xujiahui weather station, according to the city’s metrological bureau. In 1903, the coldest July day came in at a decidedly chilly 20.9 degrees, it said. The recent heavy …
