IPCC report more certain about global warming

By Robin Hammond – SciDev.Net – September 28, 2013

Development experts and scientists have reacted cautiously to leaked versions of the first part of the fifth assessment report of the Intergovernmental Panel on Climate Change (IPCC), which deals with the physical science of climate change and will be released in Stockholm, Sweden, on Monday (30 September). They say the report has confirmed climate change with greater certainty, but has shed no fresh insights, and it is unclear to what extent it will persuade national governments to reduce emissions of the greenhouse gases that cause global warming.

'Green' can equate to growth, adviser tells NUIG group

By Lorna Siggins The Irish Times September 25, 2013

Environmental science researchers need to create a “new narrative” to show that nature can nurture economic growth, British sustainability adviser Tony Juniper has said. Even campaign groups like Greenpeace and Friends of the Earth can create the false impression that there is a conflict between the environment and the economy, when in fact respect for nature can boost gross domestic product (GDP), Mr Juniper said at NUI Galway (NUIG) yesterday. Costa Rica, Belize and Brazil are examples of countries which recognised that “parallel accounting” of nature’s performance through “changing mindsets in government finance departments” could yield benefits, he told researchers at NUIG Ryan Institute’s environment gathering.

Virginia Town Forced to Adapt to Rising Seas

By Rosanne Skirble – Voice of America – September 20, 2013

No one is far from the water in Norfolk, Virginia, where citizens are feeling the impact of climate change. The port city, home to the largest naval base in the world, is a vital part of the region's economy and is critical to the nation's security. At high tide and during storms, water floods streets. Sea level is rising faster here than anywhere else on the U.S. East Coast. The city, and its residents, are learning to adapt to a warmer world. For full story, click here.

Professor speaks on coastal wetlands and climate change

By Vicki Jackson – Clearwater Gazette – August 28, 2013

Some people want to break the “hockey stick,” a graphic that climate scientists say illustrates the planet’s abrupt temperature rise, said Donny Smoak, professor of environmental science at the University of South Florida. In his Aug. 15 presentation “Climate Change and Blue Carbon” at Clearwater Marine Aquarium, he illustrated some of the many sources that he said offer evidence of global temperature rise, exceptional in later decades and contrary to the opinions of disparagers.

Climate change prompts new concerns about Delta tunnels, Sacramento water supply

By Matt Weiser – The Sacramento Bee – September 13, 2013

The Sacramento City Council this week stepped up its critique of a plan to build two giant water diversion tunnels in the Delta, warning that it may harm the city’s ability to access drinking water in the decades ahead. The Bay Delta Conservation Plan, as the tunnel project is formally known, is being pushed by Gov. Jerry Brown and a contingent of major water suppliers, mostly in Southern California and the San Joaquin Valley. The goal is to improve water delivery to farms and cities south of the Delta and also protect endangered fish. For full story, click here.

Climate change may speed up forests’ life cycles

By Thomas Anderson – TG Daily – September 12, 2013

Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response. Nearly 80 percent of the species aren’t yet shifting their geographic distributions to higher latitudes. Instead, they’re staying in place – but speeding up their life cycles.

Climate change 'driving spread of crop pests'

By Rebecca Morelle – BBC News Science & Environment – September 1, 2013

Climate change is helping pests and diseases that attack crops to spread around the world, a study suggests. Researchers from the universities of Exeter and Oxford have found crop pests are moving at an average of two miles (3km) a year. The team said they were heading towards the north and south poles, and were establishing in areas that were once too cold for them to live in.

Pacific Ocean Impacts Global Warming by Lowering Climate Temperatures

By Catherine Griffin – Science World Report – September 4, 2013

The Pacific Ocean may be having a huge impact on global warming. It turns out that equatorial cooling in the ocean is actually offsetting rises in temperatures. This finding could have major implications for the future if ocean waters begin to warm once more. For full story, click here.

Coastal Blue Carbon

U.S. Water Alliance – August 20, 2013

report released by Duke University’s Nicholas Institute for Environmental Policy Solutions draws attention to emerging scientific evidence indicating that the conversion of coastal and marine ecosystems is becoming a significant source of greenhouse gases (GHGs).  This data on blue carbon emissions raises the question of whether and how best to include efforts to mitigate these emissions.
