Arctic Ocean ‘acidifying rapidly’

BBC: The Arctic seas are being made rapidly more acidic by carbon-dioxide emissions, according to a new report. Scientists from the Arctic Monitoring and Assessment Programme (AMAP) monitored widespread changes in ocean chemistry in the region. They say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry to…

Do you believe in Global Warming?

By James West “I don’t see what all those environmentalists are worried about,” sneers your great uncle Joe. “Carbon dioxide is harmless, and great for plants!” OK. Take a deep breath. If you’re not careful, comments like this can result in dinner-table screaming matches. Luckily, we have a secret weapon: A flowchart that will help you calmly…

Jennifer Francis: Wacky Weather and disappearing Arctic Sea Ice are they connected?

Dr. Jennifer Francis – Rutgers University “Extreme weather events are increasing in frequency and intensity all around the northern hemisphere.” Concurrently, Arctic sea ice is in an accelerating decline, the entire surface of Greenland melted for the first time in at least 150 years, glaciers are disappearing around the world, and snow cover on Arctic…

Kevin Trenberth: How To Relate Climate Extremes to Climate Change

Public lecture by Distinguished Senior Scientist at the Climate Analysis Section at the National Centre for Atmospheric Research (NCAR), Kevin Trenberth held at UNSW on October 16, 2012. “Heavy precipitation days are increasing even in places where precipitation is decreasing.” Framing the way to relate climate extremes to climate change Abstract The atmospheric and ocean environment…

NASA: Warming-Driven Changes in Global Rainfall

https://www.youtube.com/watch?v=u3gV2wMQ7v0 By Kathryn Hansen NASA Goddard Space Flight Center. A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought. Model simulations spanning 140 years show that warming from carbon dioxide will change the frequency that regions around the planet receive no rain (brown), moderate rain (tan), and very…
