Beyond Lima: Major Investors
Must Fund Global Green Initiatives
Much of the discussion at the just-concluded U.N. climate talks in Lima, Peru, was about the financing that

will be needed to decarbonize the world’s energy supply, improve efficiency, and redesign cities and transportation systems to reduce greenhouse gas emissions. As journalist Isabel Hilton reports for e360
from Lima, moving the broader financial markets toward green investments is critically important in order to avoid the worst impacts of climate change. The key, Hilton writes, is to get major institutions to invest in sustainable growth, particularly renewable energy, and to get major companies and the industrial sector to understand that they must revise their strategies to address the risks of climate change.

By 2050, most U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year due sea level
Nuisance flooding projections for U.S. cities
rise, according to
a new report the National Oceanic and Atmospheric Administration (NOAA). The researchers looked at the frequency of so-called "nuisance flooding," which occurs when the water level reaches one to two feet above local high tide, and found that several cities along the East Coast are already seeing more than 30 days of nuisance flooding each year. Additional major cities — including Baltimore, Atlantic City, Philadelphia, and San Francisco — will reach or exceed that benchmark by 2030, the report says. Although nuisance flooding is not typically catastrophic or dangerous, it is often costly. The report drives home the point, researchers say, that such floods will become commonplace far earlier than 2100, which is generally cited as the date when sea level rise is likely to become damaging.
Five Questions for Gus Speth
On His Environmental Evolution
In a career that has spanned founding major environmental organizations, heading the United Nations
James "Gus" Speth
Development Programme, and serving as dean of the Yale School of Forestry & Environmental Studies, James "Gus" Speth has seen his own ideas about environmental issues change dramatically over the years. Yale Environment 360
asked Speth five questions about his new memoir, Angels by the River
; his growing recognition of the global nature of environmental problems; and his dissatisfaction with the state of the environmental movement in the United States.
Clearing forests not only releases carbon into the atmosphere, it also triggers worldwide shifts in rainfall and temperatures
Global effects of forest loss
that are just as potent as those caused by current carbon pollution and that pose great risk to future agricultural productivity, researchers report
. Deforestation in South America, Southeast Asia, and Africa may alter growing conditions in agricultural areas as far away as the U.S. Midwest, Europe, and China, the study in Nature Climate Change
finds. The researchers calculate that complete tropical deforestation could trigger atmospheric changes leading to an increase of 0.7 degrees Celsius in global temperatures, in addition to warming caused by greenhouse gases released from the deforestation itself. That would double the observed global warming since 1850, the researchers note. They say their findings indicate that many of the predicted changes associated with widespread deforestation are already occurring — from Thailand, which is receiving less rainfall at the beginning of the dry season, to parts of the Amazon, where once-predictable rainfall has shifted notably.
Interview: Bringing Civility and Diversity to Conservation Debate
For the past few years, an acrimonious debate has been ranging between two camps of conservationists. One faction
advocates protecting nature for its intrinsic value. The other claims that if the degradation of the natural world is to be halted, nature’s fundamental value — what nature can do for us
— needs to be stressed. The tone of the rhetoric has led to a petition, published this month in the journal Nature
, that criticizes both sides for indulging in ad hominem attacks and unproductive arguments that have devolved into “increasingly vitriolic, personal battles.” In an interview with Yale Environment 360
, Jane Lubchenco, former head of the National Oceanic and Atmospheric Administration, explains why she and her co-signatories are calling for a more “inclusive conservation” and why the bickering needs to stop. Read more.
President Obama yesterday announced protections for Bristol Bay, Alaska

of the most productive fishing grounds in the nation, from future oil and gas development. The president's action is expected to benefit commercial fishermen and Native Alaskans and boost conservation efforts in the region, which is roughly the size of Florida. Noting that Bristol Bay is the world's largest sockeye salmon fishery and the source of 40 percent of U.S. wild-caught seafood — a catch worth $2 billion annually — Obama vowed to ensure long-term safeguards for the bay. The region has been under protection intermittently since 1989, when the Exxon Valdez spill prompted a federal moratorium on offshore drilling. "It is a natural wonder, and it’s something that’s just too precious to be putting out to the highest bidder," Obama said in a video message
. The federal government is still considering whether to allow development of what would be North America's largest open-pit mine
in the bay's watershed.
