This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system. However, as a series, the …
Cryptosporidium is a leading cause of childhood diarrhea in low-resource settings, and has been repeatedly associated with impaired physical and cognitive development. In May 2013, an outbreak of diarrhea caused by Cryptosporidium hominis was identified in the Arctic region of Nunavik, Quebec. Human cryptosporidiosis transmission was previously unknown in this …
Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island. 'Blocking-high' pressure systems spawn most of the warming that melts Greenland surface ice Rutgers study says. These dramatic trends and global sea-level rise are linked, according to a study coauthored by Jennifer Francis, …
Autumn brings no relief following a record-breaking summer driven by rapid global warming, the Climate Council report says Record hot spells in Australia this month blurred the line between summer and autumn in another sign of rapidly advancing global warming, a Climate Council report says. The first four days of …
Rising temperatures worldwide are changing not only weather systems but also the distribution of water around the globe, thereby affecting the availability of potable water, a new study has found. Researchers analysed more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in the US …
Following a record winter in many ways, Arctic sea-ice cover seems poised to reach one of its smallest winter maxima ever. As of 28 February, ice covered 14.525 million square kilometres, or 938,000 square kilometres less than the 1981–2010 average. And researchers are using a new technique to capture crucial …
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 …
Rapidly disappearing Arctic sea ice is about to set a new record after an “absurdly warm” winter at the top of the world. For the second year running, it will have grown to cover less of the Arctic Ocean than ever before. The revelation comes as scientists are increasingly worried …
The Arctic is thawing even faster than lawmakers can formulate new rules to prevent the environmental threat of heavy fuel oil pollution from ships plying an increasingly popular trade route. Average Arctic temperatures are rising twice as fast as elsewhere in the world and the polar ice cap's permanent cover …
New data from NASA and the National Oceanic and Atmospheric Administration suggest that January of 2016 was, for the globe, a truly extraordinary month. Coming off the hottest year ever recorded (2015), January saw the greatest departure from average of any month on record, according to data provided by NASA. …
New research published in the journal Nature reaffirms that key regions of the globe that have been a source of major climate worry to researchers - such as the Amazon rainforest and the forests of the global north - are exquisitely sensitive to swings in climate. And it also identifies …
The identification of properties that contribute to the persistence and resilience of ecosystems despite climate change constitutes a research priority of global relevance. Here the researchers present a novel, empirical approach to assess the relative sensitivity of ecosystems to climate variability, one property of resilience that builds on theoretical modelling …
Climate projections of sea ice retreat under anthropogenic climate change at the regional scale and in summer months other than September have largely not been evaluated. Information at this level of detail is vital for future planning of safe Arctic marine activities. Here the timing of when Arctic waters will …
MONTREAL – Temperatures at the North Pole rose above the freezing point Wednesday, 20 degrees Celsius above the midwinter norm and the latest abnormality in a season of odd weather. Canadian weather authorities blamed the temperature spike on the freak depression that brought record Christmas temperatures to North America and …
From rain, hail and soaring temperatures to a tornado - this year's weather had it all. If Santa really did reside at the North Pole, he could probably have doffed his thick coat for a few hours this week to dig his sled out of the slush. Despite being shrouded …
The north pole could be hotter than Chicago, Vienna or Istanbul on Wednesday due to the low pressure system that has brought tornados to Dallas and high winds and heavy rainfall to the UK. The Arctic could reach temperatures about 35C (63F) warmer than average for this time of year, …
The ferocious storm cell that spawned deadly tornadoes in the US over the weekend is expected to develop into what meteorologists call a "bomb cyclone", steering exceptionally warm air over the Arctic and more flooding rains into the UK. One widely used computer model, the Global Forecast System, is predicting …
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 …
Sea ice impacts most of the Arctic environment, from ocean circulation and marine ecosystems to animal migration and marine transportation. Sea ice has thinned and decreased in age over the observational record. Ice extent has decreased. Reduced ice cover has warmed the surface ocean, accelerated coastal erosion and impacted biological …
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 …
This paper addresses questions about how the problems related to black-carbon are being addressed or could be addressed within shipping sector. It examines available technologies and ongoing regulatory efforts, as well as regulatory gaps. Following this, it proposes an Agreement on Black Carbon (ABC) as a viable means for bridging …
