Arctic Ocean Temperatures Keep Rising

Image
People's emissions are causing the planet to heat up and more than 93% of this heat goes into the oceans. People have measured ocean temperatures for a long time. Reliable records go back to at least 1880. Ever since records began, the oceans were colder than they are now. NOAA analysis shows that, on the Northern Hemisphere, the 20th century average for June is 16.4°C (61.5°F). In June 2015, it was a record 0.87°C (1.57°F) higher. Back in history, there have been times when it was warmer. The last time when it was warmer than today, during the Eemian Period, peak temperature was only a few tenths of a degree higher than today, according to the IPCC . In those days, there was huge melting, accompanied by extreme storms and sea levels that were 5 to 9 m higher than today. In many ways, the situation now already looks worse than it was in the Eemian. "The warm Atlantic surface current was weaker in the high latitude during the Eemian than today", says Henning Bauch .

Most Important Videos Uploaded In December 2016

Image
Peter Wadhams is interviewed by Stuart Scott , Executive Director of  United Planet Faith & Science Initiative , in this video called  Farewell to Arctic Ice , uploaded December 27, 2016, and recorded at UN climate negotiations in Marrakesh, Morocco. Peter Wadhams is an 'expeditionary' scientist and Emeritus Professor of Ocean Physics from Cambridge. Peter Wadhams' observations of the Arctic ice for over 4 decades makes him one of the worlds authorities on the subject. In the video, Peter Wadhams discusses some of the issues described in his current book  A Farewell to Ice  (right), which is available as hardback or ebook (256 pages, published September 1, 2016). For more, view some of the recent posts at Arctic-news blog, such as: Accelerated Warming of the Arctic Ocean Monthly CO₂ not under 400 ppm in 2016 Seafloor Methane  and Sea ice is shrinking Below is the sea ice volume image (created by Wipneus ) that is discussed in the video.

Wildfires

Image
Levels of carbon dioxide (CO2) in the atmosphere are accelerating , even though emissions from fossil fuel burning have remained virtually the same over the past few years. One of the reason behind this is accelerating emissions from wildfires as temperatures are rising. Wildfires in Nevada caused CO2 to reach levels as high as 742 ppm on July 12, 2017 (green circle image on the right). Global warming is greatly increasing the chance for what was previously seen as an extreme weather event to occur, such as a combination of droughts and storms. Heat waves and droughts can cause much vegetation to be in a bad condition, while high temperatures can come with strong winds, storms and lightning. Wildfires cause a range of emissions, including CO2, soot, methane and carbon monoxide (CO). In Nevada, CO levels were as high as 30.43 ppm (green circle image right). Above satellite image below shows the smoke plumes and the charred area. The google maps image below further shows where the fires ...
