Listen to “Earth911 Interview: Coastal Flooding In 2050 With Climate Scientist James Renwick” on Spreaker.

Turn back the clock to hear an early warning from James Renwick, co-author of the upcoming 2021 United Nations Intergovernmental Panel on Climate Change (UNIPCC) report and head of the School of Geography, Environment and Earth Sciences at Victoria University, Wellington, New Zealand, joins Earth911 to discuss the prospects for coastal flooding due to climate change. He shares troubling but important insights into how much seas have already risen since the 1800s — about one foot — and the potential for up to two feet more flooding in the coming century. He also reports the UNIPCC will acknowledge that the critical 1.5C warming threshold is locked in unless the world takes radical action to reduce emissions immediately. Humanity has already committed future generations to potentially disastrous climate impacts, he says.

Renwick explains how much water is stored in Antarctica and the projections for economic and housing losses along the U.S. East Coast, which is particularly prone to flooding because of the configuration of ocean currents. He also discusses the growing accuracy of climate models and how accelerated warming seen in recent years appears poised to continue speeding ice loss at the poles. But, Renwick argues, the international climate dialogue has shifted from resistance to acknowledgment of climate impacts and growing national and local action, which gives him hope. “Things are moving in the right direction,” he told Earth911’s Mitch Ratcliffe. “But we’ve got a lot of work to do.”

The upcoming COP26 meeting of global leaders, which was postponed to the fall of 2021 due to the pandemic, will feature many nations’ increased commitments to reduce emissions. In the meantime, he urges individual citizens to speak out and choose sustainably produced products, as well as support effective local remediation projects, such as tree-planting programs. Each of us can make a difference. Start your journey with this conversation with Professor James Renwick.

Before you throw away that empty soda bottle, wine bottle, or milk carton, think about turning it into a bird feeder.

These seven DIY projects show how to reuse common household items to make useful backyard wildlife stations. There’s something for everyone, whether you’re crafting with kids or have experience with tools. Whenever possible, choose glass instead of plastic. Experts say glass bottles last longer in the sun and are easier to clean than plastic.

1. Soda Bottle Bird Feeder

The soda bottle bird feeder is a classic project that’s easy for anyone to make. Start by saving a 1- or 2-liter soda bottle from the recycling bin. Then, find two wooden spoons, dowels, or sturdy twigs from around your home or yard. These will serve as perches for the birds.

To make one, follow the instructions from Gardening Know How: mark two sets of holes at right angles, insert the spoons or dowels, fill the bottle with birdseed, put the cap back on, and hang it up with string or fishing line. If you’re working with young kids, adults should handle the cutting.

If you prefer not to do DIY from scratch, you can buy soda bottle bird feeder kits. Just attach the tray and wire to your own bottle.

2. Milk Carton Bird Feeder

Making a bird feeder from a milk or juice carton is just as easy as using a soda bottle. The Audubon Society even has a version that’s great for kids. Cut a large opening a few inches from the bottom on one side, add a stick underneath for a perch, make two small holes at the top for hanging, decorate it, and fill with birdseed.

Keep in mind that milk cartons don’t last as long as plastic or glass feeders. Watch for signs of wear and replace your feeder when needed. Remember to recycle the old carton.

3. Tray Bird Feeder

If you have leftover wood from a home project, you can make a simple tray feeder using Birds & Blooms’ instructions. You’ll need cedar or pine scraps, an aluminum screen for drainage, panel nails, eye screws, and some chain for hanging. You should also be comfortable using a drill and hammer.

You can also reuse old windows, picture frames, or other wooden items from around the house to make a tray feeder. One Instructables tutorial shows how someone built a feeder from the wooden backing of an old bronze award.

Tray feeders bring in many types of birds, like cardinals, chickadees, woodpeckers, and mourning doves. However, they don’t keep out squirrels.

4. Floppy Disk Bird Feeder

If you have some old floppy disks lying around, you can turn them into a retro bird feeder using an Instructables guide.

You’ll need to take apart three disks, remove the magnetic film, cut a window for the seeds, put the pieces together to form a cube, and attach a string for hanging. Use tape or a hot glue gun to hold it together, then add birdseed inside.

5. Self-Refilling Glass Bottle Bird Feeder

This gravity-fed feeder is a smart upgrade from basic designs. Remodelaholic’s wine bottle bird feeder tutorial explains how to build a simple wooden platform with a notched holder that keeps an upside-down glass bottle just above the seed tray. As birds eat, gravity refills the tray with more seed.

You need only a recycled wine bottle (or any narrow-neck glass bottle) and some wood for this project. The screw-based mount makes it easy to remove the bottle for refilling. Use a low- or no-VOC wood sealer to protect the frame.

6. Plastic Bottle Hummingbird Feeder

Want to bring hummingbirds to your yard? Try this Instructables guide for making a hummingbird feeder from recycled plastic containers. It uses a pop bottle and a deli container lid, like the ones from grocery store takeout, with milk bottle caps glued on as feeding ports.

Fill the bottle with hummingbird nectar. The International Hummingbird Society suggests mixing one part white sugar with four parts water. Don’t use food coloring, honey, or artificial sweeteners. The red parts of the feeder attract the birds, not the nectar itself.

If you want something sturdier and easier to clean, Birds & Blooms offers instructions for a glass bottle hummingbird feeder that uses copper wire and a commercial feeding tube. This version takes more effort to make but lasts much longer.

7. Glass Soda Bottle Bird Feeder 

This is a step up in craft and durability, and a good reason to save that glass Jarritos or Mexican Coke bottle. Birds & Blooms’ glass soda bottle feeder tutorial pairs a recycled glass bottle with a chicken feeder base for a sturdy feeder that holds plenty of seed and will last for years.

The most involved step is drilling a hole in the bottle’s bottom using a diamond drill bit under running water to keep the bit cool so the glass doesn’t crack. A steel rod threads through the bottle and into the chicken feeder base, locked in place with a washer and wing nut; a G-hook at the top completes the hanger. To refill, simply unscrew the base, add seed, and reattach.

This DIY project requires comfort with a drill and patience with glass, but the result looks intentional and well-made, not like a weekend craft project. For the nectar-recipe and feeder-cleaning guidance that applies to all glass bottle builds, the International Hummingbird Society’s feeding page and Birds & Blooms’ black oil sunflower seed guide are solid references depending on what you’re trying to attract.

To find out where to recycle glass bottles in your area, check the Earth911 Recycling Directory. Most curbside programs don’t accept them, but many drop-off sites do.

Tips for Bird Feeders

• Clean your feeders every one or two weeks to stop mold and bacteria from harming birds.
• Hang feeders at least five feet above the ground and away from bushes where cats might hide.
• Black oil sunflower seeds attract the most types of birds.
• For hummingbird feeders, change the nectar every two or three days. In hot weather, change it even more often.
• Plastic feeders break down faster than glass ones in sunlight. Check them regularly and replace when needed.

The global energy system is changing in two big ways: it is moving from centralized fossil-fuel generation to distributed renewables, and it is becoming more digital in how energy is measured, traded, and optimized. Steve Wilhite, Executive Vice President of Advisory Services at Schneider Electric, works at the intersection of these complementary yet challenging transitions. Schneider supports more than 40% of the Fortune 500 with energy procurement and sustainability strategies, managing over $50 billion in annual energy spending. His experience shows something that pledges and press releases often miss: the biggest challenge for corporate sustainability is not money, technology, or political will. The real issue is the gap between ambition and the ability to deliver. Companies are making Science-Based Targets commitments faster than they are building the infrastructure to meet them. Scope one and two emissions are being managed better, but scope three emissions, which come from a company’s supply chain, still present a systems problem that no single company can solve alone. Schneider’s zero-carbon supplier program suggests what it takes to close this gap. When the company started its own effort to cut emissions from its top 1,000 suppliers by 50% in five years, all 1,000 signed up within two weeks. However, about 84% of them did not fully understand what they had agreed to. Achieving success meant creating measurement tools, education programs, and action plans to help the whole ecosystem, not just individual companies.

This critical conversation explores how renewable energy is bought, including the difference between physical and virtual power purchase agreements. Steve also explains why the Power Purchase Agreement (PPA) market became more complex as it grew, and why 10% fewer renewable deals closed in 2025 compared to 2024, as tech companies used up available clean energy. He also addresses a key question in clean energy: is AI helping the environment overall, or do its energy needs still outweigh its efficiency benefits? Schneider processes over a million energy invoices each month, and about 50,000 of them had issues that took 10 to 15 business days to resolve. Now, a team of AI systems can handle these in seconds. Accurate energy consumption and billing data directly affect emissions reporting, energy efficiency, and money-saving market decisions. He describes Schnieder’s approach as “frugal AI”: using the right-sized models for each task, running them on clean energy, and choosing simple solutions over complex ones. Looking ahead, electrification is building a global digital energy network in which every meter and adjustment contributes to a new system independent of central plants. As intelligence spreads, power can shift to consumers, communities, and businesses. Schneider is enabling this shift by building a mesh grid in which each point both produces and consumes energy, coordinated by AI. These changes fundamentally reshape the global energy landscape. The central question: will we intentionally build this new, distributed system, or will we repeat centralized patterns digitally?
