The Purdue Climate Change Research Center's (PCCRC) mission is to increase scientific and public understanding of the causes and impacts of climate change through fundamental research and effective education and outreach.

Forest with dead trees

Invasive pests kill so many trees each year, it’s equal to 5 million car emissions

August 14, 2019

WEST LAFAYETTE, Ind. – Invasive insects and pathogens have wreaked havoc on ash, elm, chestnut trees and others, wiping some of them almost completely from American forests. In addition to the ecological impact, a Purdue University study shows that the carbon storage lost to these pests each year is the same as the amount of […]

Cities living with a strong chance of rain

May 28, 2019

WEST LAFAYETTE, Ind. – Heavy rain can overwhelm municipal infrastructure and lead to flooding that can threaten lives and property. The U.S. alone spends millions – and sometimes billions – of dollars per year on flood recovery, and more is spent around the world. A Purdue University study led by Dev Niyogi, a professor of […]


Nature paper offers global map to understand changing forests

May 15, 2019

WEST LAFAYETTE, Ind. – An international collaboration of hundreds of scientists – led in part by the Forest Advanced Computing and Artificial Intelligence (FACAI) Laboratory in Purdue’s Department of Forestry and Natural Resources – has developed the world’s first global map of tree symbioses. The map is key to understanding how forests are changing and […]

Persistence pays off as agricultural economics Ph.D. student delves into issues of food insecurity in Niger

May 1, 2019

EKayenat Kabir, a Ph.D. student in Purdue University’s Agricultural Economics Department, is the first to admit that she did not follow a traditional path in the department while pursuing her doctorate degree. In 2015,  Kabir gave up her job in the UN World Food Programme to start her Ph.D. at Purdue. She hails from Bangladesh, […]


Large-scale forest carbon sequestration could cause food prices to skyrocket

May 1, 2019

WEST LAFAYETTE, Ind. – The Paris Agreement calls for reducing greenhouse gases enough to keep global temperatures from rising more than 1.5 degrees Celsius from preindustrial levels. This could be done by reducing emissions or capturing and storing atmospheric carbon. One of the cheapest and most efficient ways to capture and store carbon is through […]


U.S. forests’ changes are double-edged sword for environment

April 15, 2019

WEST LAFAYETTE, Ind. – Climate change, nitrogen deposition and fire suppression are leading to shifts in the types of trees that dominate American forests. These changes will have environmental consequences, potentially positive and negative, according to a Purdue University study. Songlin Fei, a forest ecologist in Purdue’s Department of Forestry and Natural Resources, with colleagues […]

How to feed the world and preserve the environment

April 10, 2019

WEST LAFAYETTE, Ind. — Farmers bear much of the burden for growing the food to feed billions of people as the world’s population continually trends upward. But to do so, those farmers have to keep crops healthy and high-yielding. That necessitates using fertilizers and pesticides, which help crops but can have an inadvertent, negative impact […]

Katharine Hayhoe

Climate scientist Hayhoe to address ‘science in a fact-free world’ at Purdue symposium

March 14, 2019

Purdue’s Ecological Sciences and Engineering program will partner with the Purdue Climate Change Research Center to host Katharine Hayhoe, a world-renowned climate communicator, at ESE’s annual symposium March 26-27. This year’s ESE symposium is titled “In Data We Trust? Perceptions of Science in a Post-truth World.” The main event, featuring Hayhoe’s lecture, “Science in a […]

Energy demand, sources will change with Indiana’s climate

February 20, 2019

WEST LAFAYETTE, Ind. – Hoosiers will heat homes and businesses less but rely more on air conditioning as Indiana’s climate warms. They’ll also get more of their energy from natural gas and renewable sources as those become more cost-effective throughout the rest of the century. That’s according to the latest Indiana Climate Change Impacts Assessment […]

Climate drives link between forest biodiversity and productivity

January 24, 2019

WEST LAFAYETTE, Ind. – Some ecologists believe that species richness is positively related to ecosystem productivity, while others conclude that the relationship is bell-shaped or they are unrelated. Using big data, Purdue University scientists now know which theory is correct – all of them. Biodiversity-productivity relationships would be useful to natural resource managers who want […]
