A group of 50 climate activists made their way into Pittsburgh from Los Angeles Tuesday — on foot.

The Great March for Climate Action” is the brainchild of former Iowa State Representative Ed Fallon.

He said the idea came to him last February, after a discussion with environmental activist Bill McKibben about how best to address the what he calls the “climate crisis.”

“It’s not an issue; it’s a crisis,” Fallon said.

The United Nations Climate Summit took place in New York City this week. While more than 100 world leaders took part, and thousands demonstrated in the streets of NYC for the People's Climate March, it's not certain how much, if any, tangible action will be taken on a global scale, especially on the part of the United States.

Len Frenkel only has a minute to talk because he's rushing between presentations at the University of Pittsburgh’s Johnstown campus. The North American Vegetarian Society has their annual gathering here. Frenkel’s traveled from Bethlehem, Pennsylvania.

He’s not just a vegetarian, he's vegan. That means he doesn’t eat meat or butter or anything made from animals. He started for animal welfare and health reasons. But now, climate change weighs heavily on Frenkel’s mind.

'Order in the Chaos' Found by CMU Researchers Examining Brown Carbon

A team of researchers, including some from Carnegie Mellon University, have figured out a hard-to-understand pollutant called brown carbon.

A lot of attention is paid in the media to pollutants that contribute to climate change, especially to greenhouse gas emissions from power plants and other sources. But, some sources are lesser-understood and don’t come from areas that can be regulated — namely brown carbon, which comes from smoke from wildfires.

While there is little doubt in the scientific community that the globe is getting warmer, many countries balk over climate regulations given the perceived cost of such action.

David Titley, the director of Penn State's Center for Solutions to Weather and Climate Risk, believes there is connection between the climate battles of today and World War I, the world’s greatest danger a century ago.

If even hearing the word “ragweed” makes your eyes water, you might be one the nearly 45 million Americans with seasonal allergies. And allergists say the number of people with sensitivities to ragweed and other plants is growing. Our series on the local impacts of climate change continues, with a look at how higher temperatures are fueling the rise in allergies and asthma.

Health Officials: Climate Change Expected To Have Local Impact In Decades Ahead

Following the release of national reports on climate change, Allegheny County Health Department officials are examining how best to prepare for the changes they say are imminent over the coming decades.

“It’s going to change the air pollution levels, it’s going to change the pollen levels, it’s going to change insects, it’s going to change water quality,” said Jayme Graham, Air Quality Program manager at ACHD. “What do we need to know about that, and what do we need to start preparing for that?”

Climate Change Could Make Pennsylvania's Ecosystems Resemble Alabama

By 2050, Pennsylvania's ecosystems could be vastly different if we don't pass an appreciation for nature along to the next generation.

A national climate change study released earlier this week warns of drastically different climates in the future for the state of Pennsylvania.

The commonwealth is among a number of Northeast states expected to experience heat waves and extreme precipitation.

Cities such as New York have already begun to prepare for climate change effects by installing flood pumps in their subway systems.

John Radzilowicz, Director of Professional Development ASSET STEM education at CMU said, if we don’t start making big changes in industrial pollution policies and even simple conservation changes on a personal level, the Pennsylvania landscape will be completely different by 2050.

Maple trees could be in trouble in the Northeast U.S. in the coming decades. Federal climate models have predicted the region will lose most of its maples by next century. But producers don't seem worried: maple syrup prices are high, and with technology, the sap is flowing just fine.

Jason Blocher’s livelihood each year largely depends on the weather in February and March. He’s the third generation in his family to run Milroy Maple Farms in Somerset County, on Pennsylvania’s southern border, just a few miles from Maryland.

Extreme weather caused by climate change concerns many for ecological and economic reasons, but policy researchers have found that the severe elements may also have an influence on national security.

The American Security Project (ASP) is a small non-partisan think tank based in Washington, D.C. which investigates threats to national security.

Andrew Holland is a senior fellow for energy and climate policy at the ASP and explains that the effects of climate change are, in a way, threats to infrastructure much like terrorism.

Think Tank Points to Link Between Climate Change and National Security

There is a direct connection between national security and climate change, according to the American Security Project (ASP), a small non-partisan think tank based in Washington, D.C.

Senior flag officers from ASP are touring the country to talk about the connection between energy, environmental policy and national security. Senior fellow for energy and climate policy Andrew Holland said they will be talking to people outside of the traditional environmental groups, including businesses, veterans groups and lawmakers, about how a changing climate affects homeland security.

How to Address Climate Change In Light of New Reports

More conclusive findings from the IPCC, what can be done at this point?

According to a more report conclusive from the Intergovernmental Panel on Climate Change, and internationally renowned climatologist, Dr. Raymond Bradley, global temperatures have risen rapidly in the last 100 years, especially in the last 50 years. Experiments have also proven that greenhouse gases do create more heat in the atmosphere.

In addition to raising temperatures, greenhouse gases change precipitation patterns, meaning some areas that usually have heavy rainfall experience dry spells, and other areas get extremely heavy rainfall. Bradley says these effects will continue to occur more often if greenhouse gases continue to fill the atmosphere.

Before exploring the issue of creating green jobs in the 21st century economy, Essential Pittsburgh took the time to air some answers to environmental questions from listeners.

In response to a question on why the energy conversation won't embrace the possibility of more drastic advances in alternative energy such as nuclear fusion, James Clad, a consultant and distinguished research fellow at the National Defense University acknowledged that the energy conversation had been turned into a one note discussion on fossil fuels. 

"The energy world is defined by oil and gas and everything else is just an add on." said Clad

United Nations Report Examines "Climate Extremes" Over Past Decade

Extreme weather, greenhouse gases, carbon monoxide and glacial melting; all these buzzwords have increasingly entered the public vernacular in the past 20 years. 

Following a UN report by the World Meteorological Organization, scientists expect that the topic of global warming and climate change will continue to be a hot issue.  The report, “The Global Climate 2001-2010: A Decade of Extremes,” cites that the past decade has seen an abundance of greenhouse gas emissions that has caused increased temperatures on both hemispheres, all oceans and an accompanying rapid decline in arctic sea ice and glaciers. 

Director of Science at the Carnegie Science Center, John Radzilowicz, has been following the topic of global climate change and was not necessarily surprised by the UN report.  He was optimistic, however, that the report was gaining attention and combined a multitude of data pointing to the extremes in weather conditions throughout the world.
