Wildlife in Hot Water: Philadelphia Edition

This is the first in a multi-part series localizing the National Wildlife Federation's (NWF) recent report, Wildlife in Hot Water: America’s Waterways and Climate Change.

Last week, PennFuture joined the NWF in Scranton to release its new report, which examines the affects climate change is having on wildlife and the nation’s waterways. 

The report details the rapid changes to the Earth’s water cycle that are already having negative impacts on ecosystems. As a result of disruptive carbon pollution, these changes include earlier and more rapid snowmelt, fewer and more intense rainfall events, and more frequent and extreme droughts and floods. The very character, chemistry, and quality of our waterways are changing in some of the following ways: 

• Reduced dissolved oxygen levels in streams and lakes
• Loss of habitat for cold and cool water fish species as climate change is prompting warmer temperatures
• Loss of wetlands and reduced riparian/floodplain connectivity
• Loss of upstream/downstream connectivity caused by the drying of stream and river reaches
• Reduced extent, diversity, and quality of in-stream habitat for aquatic biota
• Increased pollutant concentrations from urban and agricultural runoff

These effects are already being felt throughout Pennsylvania. Last Wednesday, speakers at our press event discussed the negative effects of climate change on water and wildlife in the Lackawanna and Susquehanna Rivers. But northeast Pennsylvania isn’t the only region of the commonwealth feeling these effects. The City of Philadelphia, bordered by two tidal rivers, is particularly at risk to sea level rise and extreme weather events. 

Flooding on Kelly Drive in Philadelphia

Some findings concerning Philadelphia and climate change-related flooding:

• According to the National Oceanic and Atmospheric Administration (NOAA), nuisance flooding in Philadelphia – think road closures, overwhelmed storm drains, and infrastructure damage – has increased by 650 percent over the past 50 years. This significant increase is due to many factors, including climate-related sea level rise. NOAA concluded in its report that acceleration in sea level rise “will further intensify nuisance flooding impacts over time, and will further reduce the time between flood events.” 
• Sea levels in the Delaware Estuary have already risen by about a foot in the last century and experts expect to experience a rise of at last three more feet within ninety years.
• A report from the Union of Concerned Scientists projects that over the next thirty years tidal flooding events in Philadelphia will grow in frequency from 19 to 200 per year.
• The National Weather Service’s Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model shows the that large sections of Philadelphia would be inundated if a Category 1 or 2 hurricane were to directly impact the region. In particular, southwest Philadelphia, which includes the Eastwick neighborhood as well as Philadelphia International Airport, would be particularly vulnerable to surge flooding where water levels would be higher than the elevation of the area. In an op-ed in Plan Philly’s Eyes on the Street blog, author Amy Laura Cahn shares that during Hurricane Floyd, “Eastwick’s slab-on-grade homes filled with six feet of water.” As a result, Eastwick residents have experienced spikes in the cost of flood insurance. 

Without climate action, it is expected that the rate of sea level rise will accelerate and extreme weather events will occur with greater frequency. Fortunately, there are many options for combating the causes of climate change while simultaneously preserving and protecting wildlife and the waterways they depend on, including: 

• Supporting the Clean Power Plan and reducing our carbon footprint: The Environment Protection Agency’s Clean Power Plan is an important step first step toward mitigating climate change. The plan presents opportunities to not only reduce carbon pollution from existing power plants, but to also invest in a zero-carbon, clean energy future. The commonwealth should expand upon its existing wind, solar, and energy efficiency programs to meet our reduction goals in a manner that is both cost-effective and emissions-neutral. 
• Encouraging Clean Water Act Protections: In order to better protect our wildlife and waters, support for the Clean Water Rule is essential. Without this rule, at least 60 percent of America’s streams and 20 million acres of wetlands would be left vulnerable to the destructive hands of industrial activities. 

In the coming weeks, we plan to share more region-specific stories that underscore the need to act on climate to protect our waterways and wildlife. Stay tuned!

Zombie bill intent on dirtying your water

With fall approaching and Halloween right around the corner, I thought I’d share a frightening tale with you. Here at PennFuture, we have been dealing with a “zombie bill” for over a year and just like real zombies, this bill rises up again and again from the (almost) dead. It may well take an outpouring of citizens to finally kill the bill as the clock moves toward midnight at the end of the legislative session.

What ghoulish bill do I speak of? House Bill 1565 (insert blood-curdling scream)! This proposed legislation would remove riparian forest buffer requirements for our best waters -- those designated as exceptional value (EV) or high quality (HQ). These requirements, established just a few years ago, acknowledge the importance of forested buffers to our water quality, wildlife, and communities. Now, there are some in Harrisburg who want to remove these protections because they believe we can either get by without them or engineer controls, such as rain gardens and wet detention ponds, to do the same things forested buffers do, but that’s just not true.

The unique benefits of maintaining or installing forested buffers are many, including:

           ·          filtering pollution from agriculture and other land uses, improving water quality

           ·          natural flood control for downstream communities

           ·          preventing erosion and stabilizing the stream bank. This helps to maintain the natural width, depth, and sediments of a stream

           ·          improving stream health, which increases the level of in-stream processing of pollutants

           ·          providing habit and food for aquatic life, and shade which keeps temperatures stable

           ·          increased opportunities for fishing, kayaking, and hiking

           ·          increased property values by preserving scenic beauty and natural character

It’s clear that forested buffers provide more than just water retention and sediment removal. How could we engineer shade, aquatic food and habitat, or scenic beauty? A better question might be, why pay to engineer and maintain systems when forest buffers do everything they do, and more, for free?

Additionally, under the Chesapeake Bay pollution limits, Pennsylvania committed to establish forest buffers to reduce pollution from its part of the watershed, but we have fallen behind in meeting our commitments. To achieve our 2017 goal, we need to establish roughly 50 acres of riparian forest buffers every day through 2017. In the recent Chesapeake Bay Agreement, Pennsylvania, along with the other Bay states, has also agreed to conserve existing forest buffers until at least 70 percent of riparian areas throughout the Bay watershed are forested. Given our commitments, we should be doing everything we can to preserve existing buffers and establish new ones, but HB 1565 will do just the opposite (insert second blood-curdling scream).

Sharpen your wooden stake…no wait, that’s for vampires. Get your silver bullet…sorry, wrong again. That’s for werewolves. Stay tuned to find out how you can help put an end, once and for all, to this zombie bill.
