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 …
This year has got off to a scorching start, with global temperatures marching to new highs as a giant El Nino rode on the back of creeping climate change, data from Japan and the US show. Just a month after the world notched its hottest year on record, January's global …
Aircraft do not fly through a vacuum, but through an atmosphere whose meteorological characteristics are changing because of global warming. The impacts of aviation on climate change have long been recognised, but the impacts of climate change on aviation have only recently begun to emerge. These impacts include intensified turbulence …
The Earth is known to be able to restore its temperature equilibrium after a period of natural warming. But the phenomenon tends to be overwhelmed locally by external drivers like greenhouse gases that can cause sustained changes in global temperature in the long run, a study has found. Researchers at …
Japan's meteorology agency said on Wednesday that the El Nino weather pattern, which is often linked to heavy rainfall and droughts, had somewhat weakened and that the weather would likely return to normal by summer. The Japan Meteorological Agency said last month that the El Nino phenomenon peaked between November …
We've all heard that the phases of the moon influence rainfall. A high moon in the sky creates bulges in the planet's atmosphere, which creates indistinguishable changes in the amounts of rainfall. However, researchers at the University of Washington found that lunar forces have a very small effect on the …
Above-average temperatures are set to linger for the upper half of the North Island and many other regions over the next three months, as a strong El Nino keeps its grip on the country's climate. But farmers have breathed a sigh of relief that the ocean-driven system has so far …
Classical tidal theory predicts that the lunar gravitational semidiurnal tide (L2) should induce perturbations in relative humidity (RH). Adiabatic expansion in divergent flow in advance of the L2 pressure minimum cools the air and reduces its saturation vapor pressure, thereby increasing the rate of condensation in saturated air parcels and …
This study unravels the physical link between the weakening of the monsoon circulation and the decreasing trend in the frequency of monsoon depressions over the Bay of Bengal. Based on the analysis of the terms of Genesis Potential Index, an empirical index to quantify the relative contribution of large scale …
HIGHWAYS have been closed and airport traffic was disrupted as the worst cold front in years hit several Chinese provinces. Starting from 8 a.m. on Friday, highways in at least 12 provinces and municipalities have been closed due to blizzards and snowstorms. A large part of Jiangxi province, in eastern …
Data-based projections suggest that the natural CO2 cycle could be amplified by up to ten times by 2100 in some oceanic regions if atmospheric CO2 concentrations continue to increase, which could detrimentally affect major fisheries.
A strong El Nino weather pattern will likely end in the second quarter of 2016, the Australian Bureau of Meteorology said on Tuesday. Climate indicators remain in the El Nino threshold but have cooled in recent months, with a likely return to neutral conditions within six months, it said.An El …
Half of the global ocean heat content increase since 1865 has occurred over the past two decades, says a new study. "In recent decades the ocean has continued to warm substantially, and with time the warming signal is reaching deeper into the ocean," said lead study author Peter Gleckler from …
Last year wasn't just the Earth's hottest year on record _ it left a century of high temperature marks in the dust. The National Oceanic Atmospheric Administration and Nasa announced on Wednesday that 2015 was by far the hottest year in 136 years of record keeping. NOAA said 2015's temperature …
Last year’s global average temperature was the hottest ever by the widest margin on record, two U.S. government agencies said on Wednesday, adding to pressure for deep greenhouse gas emissions cuts scientists say are needed to arrest warming that is disrupting the global climate. Data from U.S. space agency NASA …
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 …
Climate change made the UK’s record December rainfall, which caused the devastating floods, 50-75% more likely, a preliminary scientific investigation has found. “Greenhouse gas emissions are loading the weather dice towards these warmer, wetter winters,” said Friederike Otto, scientific coordinator of the climateprediction.net project, which harnessed the collective power of …
Climate troublemaker El Niño's strength — already tied for the most powerful on record — will peak within the next month before weakening in the spring, according to a forecast issued Thursday. That means the USA is set to receive even more desperately needed rain and snow in the drought-plagued …
The Parties to the Montreal Protocol are informed by three Panels of experts. One of these is the Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is the effects of increased UV radiation on human health, animals, plants, biogeochemistry, air quality, and materials. The …
Precipitation associated with the South Asian summer monsoon has decreased by approximately 7% since 1950, but the reasons for this are unclear. Now research suggests that changes in land-cover patterns and increased emissions from human activities have contributed to this weakening, which is expected to continue in the coming decades.
Australia has posted its hottest end to any year as the impact of one of the biggest El Ninos on record began to be felt across the continent. Mean temperatures were 0.36 degrees above the previous record for the October to December period, capping what was Australia's fifth-hottest year since …
