Introduction

Unlike reptiles or birds, which have hard-shelled eggs, amphibians have jelly-like, unshelled eggs that cannot survive desiccation. Amphibians need moist climates to reproduce, and this makes them extremely sensitive to climate change. Frogs in high mountainous areas are most affected by global warming. The climate change debate always seems to focus on the potential harm that may happen in the future if we don't act now. We need to make sure people know that climate change is ALREADY causing huge problems for the frogs!

Climate Change in Tropical Regions

Global warmingIn many areas of the world, especially in the tropics, mountainous areas have extremely high amphibian biodiversity. For instance, some sites in the mountains of Costa Rica and Panama may have up to 60 species. In these tropical montane areas, many of the amphibians live in cloud forests, and lay their eggs in the moist leaf-litter. As the eggs are laid away from water bodies, the embryos bypass the aquatic tadpole stage and hatch directly into tiny froglets. These 'direct-developing' species (like the Marsupial Frog Assa darlingtoni pictured here) are under serious threat from global warming, which acts to raise the cloud levels. If the cloud's average elevation increases a few hundred meters, the frogs at the newly-exposed lower elevations lose their habitat (and their lives) as the soil dries.

Climate changeWhile the affected frogs could potentially move up the mountain to find cool, moist habitat, many frog species already live at the tops of mountains, so when their habitat dries or warms, they have nowhere left to go. Another issue is that mountains are shaped like cones, and at a given elevation, there is less total area at higher elevations, so an amphibian that is forced to higher elevations would find itself in potentially crowded conditions. Further, some frog species live only on a single mountain range, or even on a single mountain, so when problems arise they are extremely prone to extinction. In Guatemala, several salamander species have completely disappeared as their cloud forest habitats have dried.

Climate change also affects host-parasite relationships. The deadly chytrid fungus (Batrachochytrium dendrobatidis) is expanding its elevational range in the high Andes of Peru as the glaciers melt and new lakes are formed. The fungus was recently found infecting Telmatobius frogs as high as 5348m elevation.

Climate Change in Temperate Regions

Yellowstone FrogsPond-breeding species are dependent on water bodies that do not dry up before their tadpoles can metamorphose. In Yellowstone National Park, droughts have been increasing over the last 50 years, and 25% of the ponds that existed in the early 1990's no longer fill with water. As the four amphibian species in the park are pond-breeders, it is not surprising that three of the four species are thought to now be declining in numbers, such as the Columbia Spotted Frog (Rana luteiventris) pictured here. Learn more about climate change in Yellowstone here.

Pseudacris maculata pond dryingYellowstone is the world's oldest protected area, having been preserved as a National park since 1872, so if climate change is already affecting the park's wildlife, we have to assume that climate change is having an even more significant effect elsewhere in the world, where habitat destruction, pollution and pesticides, and over-harvesting are likely to compound matters.

In the United Kingdom, warm years stunt the growth of Common Toads (Bufo bufo) in the United Kingdom. In warm years, females were thinner, laid fewer eggs, and had reduced survival rates. Read more in this article by C.J. Reading.

Climate Change and Santa Cruz Long-Toed Salamanders

One of the western hemisphere's most endangered amphibians, the Santa Cruz Long-Toed Salamander (Ambystoma macrodactylum croceum) is endemic to a small section of coastal California not far southeast of the city of Santa Cruz, home of SAVE THE FROGS! World Headquarters. Only 23 populations of the salamander are known to exist.

"I am also working on the long-toed salamander; as fog disappears it will vanish. This is a certainty. It relies on summer fog to come out and forage at night even in summer. I am instrumenting the area with fog collectors to figure out how much fog there is, whether it is decreasing (a paper by a colleague Todd Dawson suggests this might be so). Thus, this is huge priority for me. I am also working with climate scientists to predict changes in fog into the future."

Nine ways to reduce your carbon footprint

While governmental action is an integral part of stopping global warming, every one of us is responsible for reducing our own carbon footprint. Here are nine easy ways you can do your part:

Turn off the lights

If you're not in the room (or the house), you probably don't need the lights on. Same with your office-place, and those lights in the parking lot. Try solar power for outside lights.

Don't purchase bottled water

Plan ahead and fill your re-usable bottle. Not only is plastic produced from oil, but it takes fuel to get that bottle of water from the source to the store at which you buy it.

Eat less meat

Cows live in pastures, which means rainforests worldwide are being destroyed to make way for cows. Without the rainforests to trap carbon, we don't stand much of a chance at fighting global warming. But that's not it: cows, pigs, sheep and goats are responsible for about 30% of America's methane emission -- and methane is far worse for the environment than carbon dioxide!

Take shorter showers

There is a high chance your hot water is being heated by electricity generated at a coal-fired power plant.

Don't fly first-class

Airplanes produce significant quantities of carbon emissions, and those spacious first-class seats take up 50% more space than do normal seats. That means you'e responsible for 50% more of that plane's carbon emissions than economy passengers.

Invest in environmentally-friendly businesses

If a company puts effort into improving their environmental practices, they likely have some information about it on their website. Do some research prior to investing, and then give your support to companies with positive environmental track records.

Drive less. Buy and rent smaller cars.

Eat at a restaurant closer to home, or stay home and eat. Get yourself a good book and try the local public transport sometime (it's probably improved since the last time you used it!). And next time you buy or rent a car, go with a fuel-efficient small car unless you have a true need for a large vehicle.

Climate Change Frogs

 

"Amphibians are actually very vital to most ecosystems! They control the insect populations, and they are very susceptible to the increase in temperatures. If the temperatures keep rising, the amphibians will no longer be able to acclimate - thus killing off many species of amphibians. As the populations of amphibians decrease, then the insect populations will inevitably increase - paving way to an equally-inevitable increase in disease." 
-- Jason Emmick, University of South Dakota

SAVE THE FROGS! at Climate Rally February 17, 2013

SAVE THE FROGS! and 80 other environmental organizations rallied with thousands of people in San Francisco for urgent action on climate change. Protesters called on the Obama Administration to do much more to tackle climate change, including rejecting the Keystone XL Pipeline, which would bring carbon-heavy tar sands oil from Canada through the U.S. to a world market. The rally in San Francisco was organized in solidarity with the rally in Washington D.C., which gathered over 35,000 people, making it the largest climate march in U.S. history. The impacts of climate change are one of many threats that face amphibians and bring them ever closer to extinction. Amphibians need moist climates to reproduce, and this makes them extremely sensitive to climate change. In order to bring awareness to these threats we marched for the frogs!

In 2010, Texas-based Valero Energy pumped millions of dollars into supporting California's Proposition 23, which if passed would have suspended legislation (AB 32) that requires significant reductions in greenhouse gases that cause global warming and climate change. That would have spelled disaster for the Arroyo Toads: less snowfall and higher summertime temperatures cause the toads’ ponds and streams to dry up…and no water means no toads. Turn up your speakers and watch this video to learn more. Enjoy!

Not about frogs, but a good talk on climate!

What's 350?

Scientists say that 350 parts per million is the upper limit of carbon dioxide we can safely have in Earth's atmosphere. Right now we are around 390 parts per million -- and frogs are paying the price.

Keeping fossil fuels in the ground

SAVE THE FROGS! joined Friends Of The Earth and 400 other groups in signing this letter to President Obama, asking him to stop federal leasing of public land for fossil fuel extraction.

On Tuesday morning, September 15th, 2015 a press conference to announce the letter was held in front of the White House. Afterwards, our partners met with staff at the Council on Environmental Quality and Department of the Interior to discuss the policy implications of the letter for the remainder of President Obama's term and beyond.

By signing this letter, SAVE THE FROGS! joined over 400 other diverse groups and individuals from all over the country to lend both urgency and a way forward to confront climate disruption and the other devastating environmental, health, and wildlife impacts of fossil fuel development on our public lands and waters. But this letter is just the beginning. Thank you again for supporting SAVE THE FROGS! as we protect our public lands and waters and educate people on ways to reduce their climate footprint.
