NOVEMBER 2017
New National & Global Reports
The first volume of the 4th National Climate Assessment (NCA4), titled The Climate Science Special Report (CSSR), was released earlier this month by the U.S. Global Change Research Program. This report, which is mandated by law under the Global Change Research Act of 1990, provides detailed analysis of past and future climate conditions in the U.S. and serves as the foundation for subsequent reports on the societal and environmental implications of shifting climate patterns. Nearly 100 experts nationwide collaborated on the development of this report using a rigorous scientific process and the best available data and information.
The 477-page CSSR includes 15 detailed chapters covering topics such as the detection and attribution of climate change, trends in temperature and rainfall, analysis of extreme storms, and even potential surprises and climate tipping points. An Executive Summary is available.
_____________________________

Also released in this month was the 2017 Global Carbon Budget, an annual update on global carbon trends.
Highlights include:
  • CO2 emissions from fossil fuels are projected to grow by 2% in 2017, following three years of no growth (2014 - 2016).
  • China, U.S., European Union, and India are the top four emitters of CO2 in the world.
  • Per capita emissions in the U.S. remain the highest in the world, but have substantially declined over the last two decades.
  • Atmospheric concentrations of CO2 are continuing to rise.
A full summary of findings along with infographics and other resources are available from the Global Carbon Project website.
IN CCIA Media Resources Now Available
As we prepare for the release of the IN CCIA in 2018, last month we issued a news story describing the Indiana Climate Change Impacts Assessment effort, contributors and goals. We also updated our Resources page with logos, infographics, and a Media Resources kit.

Stories of Change
Documenting personal stories about climate impacts across Indiana
The Purdue Climate Change Research Center invites people who live and/or work in Indiana to share their personal connections to our climate. How does our climate affect your lifestyle and livelihood?  What changes have you observed? What impacts have you faced? What does climate change mean to you, now and in the future?

We've been talking to farmers, bird watchers, doctors, educators, religious organizations, conservation specialists, and many others across the state about their observations and impacts of changes in our environment. We'd like to hear from you too. Do you have a story to share or would you like more information? Please contact Melissa Widhalm (IN CCIA coordinator) or see our May 2017 newsletter.

Climate Facts


Did you know?
Anyone with a ginkgo tree in their yard knows to keep their rakes and trash bags nearby when the weather forecasters say the first hard freeze of fall is coming. That's because unlike other trees, the ginkgo will drop all of its leaves in a single day when temperatures dip to about 20-25°F.
At the University of New Hampshire, since 1977 students have made a game out of this spectacular autumn show by trying to guess the exact date of the ginkgo leaf-drop. As described earlier this month in The Atlantic, when they looked at the leaf-drop date over time they found it was happening later and later. This trend is consistent with observed warming in the region.

At Purdue University in West Lafayette, Indiana, the 2017 ginkgo leaf-drop occurred on November 10. Although we don't have historical observations of the ginkgo leaf-drop (that we know of) like they do in New Hampshire, there is a weather station on campus with consistent temperature observations dating back to the mid-1960s. The observations show that on the Purdue campus, the first hard freeze of the fall (defined here as 23°F as an estimate for when the ginkgo tree will drop its leaves) is happening about two weeks later nowadays compared to the mid-1960s. That means we can estimate that the annual ginkgo leaf-drop is also happening about two weeks later.
Caption: This graphic shows the observed date of the first 23°F freeze each autumn from 1964 - 2017 at the Purdue University Airport in West Lafayette, IN. Years with six or more days of missing observations have been excluded. Data were accessed from the High Plains Regional Climate Center CLIMOD Database.
About Us:
 
Led by the Purdue Climate Change Research Center, the Indiana Climate Change Impacts Assessment (IN CCIA) is a statewide effort that will bring together the best available climate change research into a series of reports that will help Hoosiers better understand climate change-related risks so they can prepare for challenges and capitalize on opportunities.
