Global warming made 2014 a record hot year in animated graphics
2015-01-16 16:37:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: NASA and NOAA have just reported that global surface temperatures in 2014 were the hottest on record. That also means 2014 was likely the hottest the Earth has been in millennia, and perhaps as much as 100,000 years. But whats really remarkable is that 2014 set this record without the aid of an El Nio event. El Nio events create conditions in which sea surface and hence global surface temperatures are anomalously hot. We call this part of the Earths internal variability because these events...
Global warming is here and Australia is feeling the impact
2015-01-16 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
SBS: In the early Saturday morning hours, Australian time, NASA and the National Oceanic and Atmospheric Association is expected to officially pronounce 2014 as the hottest global year on record. The follows the same finding last week from the Japan Meteorological Association. This is significant news. The joint NASA/NOAA statement has been anticipated for weeks. As the primary repositories of US and global climate data, the statement is generally seen as the conclusive report card of the year just...

Tropical forests may reduce global warming rate
2015-01-08 16:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: A new study led by NASA and the National Center for Atmospheric Research (NCAR) shows that tropical forests may be absorbing far more human-emitted carbon dioxide than many scientists thought. The study estimates that tropical forests absorb 1.4 billion metric tons of carbon dioxide out of a total global absorption of 2.5 billion, in response to rising atmospheric levels of the greenhouse gas. This means, if left undisturbed, the tropical trees should be able to continue reducing the rate of global...

Global warming changing taste wine
2015-01-04 01:05:00| Climate Ark Climate Change & Global Warming Newsfeed
ZeeNews: The taste of some of the world's finest wines is changing as global warming alters the way grapes mature, scientists have found. Grapes such as pinot noir, merlot and chardonnay are now growing more quickly, subtly changing the compounds produced as they ripen and the synchronisation between maximum flavour and the ratio of sugar to acid, scientists said. An increasing number of vineyards are thus struggling to identify the perfect moment for picking the grapes to ensure their wines retain...

Global warming will cut wheat yields, research shows
2014-12-23 11:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Global wheat yields are likely to fall significantly as climate change takes hold, new research has shown . The researchers found that wheat production would fall by 6% for every 1C increase in temperatures. The world is now nearly certain to warm by up to 2C compared with pre-industrial levels, with political efforts concentrated on holding the potential temperature rise to no higher than that limit. But some analyses suggest that if greenhouse gas emissions continue to grow at current rates...
