Climate Change

Overview

Sea levels are rising and oceans are becoming warmer. Longer, more intense droughts threaten crops, wildlife and freshwater supplies. From polar bears in the Arctic to marine turtles off the coast of Africa, our planet’s diversity of life is at risk from the changing climate.

Climate change poses a fundamental threat to the places, species and people’s livelihoods WWF works to protect. To adequately address this crisis we must urgently reduce carbon pollution and prepare for the consequences of global warming, which we are already experiencing. WWF works to:

  • advance policies to fight climate change
  • engage with businesses to reduce carbon emissions
  • help people and nature adapt to a changing climate

Climate change has an impact on turtle nesting sites. It alters sand temperatures, which then affects the sex of hatchlings.

Causes

Clearing forests, such as in the National Forest of Bom Futuro, Rondônia, Brazil, adds more carbon dioxide to the atmosphere.

Clearing forests, such as in the National Forest of Bom Futuro, Rondônia, Brazil, adds more carbon dioxide to the atmosphere.

Greenhouses gases, such as carbon dioxide, trap heat in the atmosphere and regulate our climate. These gases exist naturally, but humans add more carbon dioxide by burning fossil fuels for energy (coal, oil, and natural gas) and by clearing forests. Greenhouse gases act like a blanket. The thicker the blanket, the warmer our planet becomes. At the same time, the Earth’s oceans are also absorbing some of this extra carbon dioxide, making them more acidic and less hospitable for sea life.

The increase in global temperature is significantly altering our planet’s climate, resulting in more extreme and unpredictable weather. For instance, heat waves are becoming more frequent and many places are experiencing record droughts followed by intense rainfalls.

Deforestation

Forests help protect the planet by absorbing massive amounts of carbon dioxide (CO2), the most abundant type of pollution that causes climate change. Unfortunately, forests are currently being destroyed or damaged at an alarming rate. Logging and clearing land for agriculture or livestock release huge amounts of carbon dioxide and other harmful greenhouse gases into the atmosphere. It also diminishes those regions’ ability to absorb carbon pollution.

20%

Scientists estimate up to 20 percent of global carbon emissions come from deforestation – greater than emissions from every car, truck and plane on the planet combined.

Scientists Agree, Humans Cause Climate Change

Burning coal releases 70% more carbon dioxide than natural gas. Coal plant, Taiyuan, China.

Scientists in the United States and the world have reached an overwhelming consensus that climate change is real and caused primarily by human activity. Respected scientific organizations such as the National Academy of Science, the Intergovernmental Panel on Climate Change (IPCC) and World Meteorological Association (WMO) have all identified climate change as an urgent threat caused by humans that must be addressed.

“The need for urgent action to address climate change is now indisputable.”

— National Academy of Science

Fossil Fuels

Burning fossil fuels, such as coal, oil and natural gas, to generate energy has the greatest impact on the atmosphere than any other single human activity. Globally, power generation is responsible for about 23 billion tonnes of CO2 emissions per year – in excess of 700 tonnes every second. Coal is especially damaging to our atmosphere, releasing 70% more carbon dioxide than natural gas for every unit of energy produced.

Impacts

Climate_Change_7.24.12_Threat

Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities.

U.S. Cities at Risk
As climate change worsens, dangerous weather events are becoming more frequent or severe. People in cities and towns around the United States are facing the consequences, from heat waves and wildfires to coastal storms and flooding.

What WWF Is Doing

To adequately address the climate crisis we must urgently reduce carbon pollution and prepare for the consequences of global warming, which the world is already experiencing. Combining global outreach with local expertise, WWF:

  • helps people and nature adapt to a changing climate
  • advances policies to fight climate change
  • combats deforestation
  • engages with businesses to reduce carbon emissions
  • challenges U.S. cities to prepare for more extreme weather

Challenging Cities to Prepare

As climate change worsens, dangerous weather events are becoming more frequent or severe in the United States and around the globe. WWF is challenging U.S. cities to reduce their carbon footprint and implement practical measures to prepare for extreme weather and other consequences of climate change through the Earth Hour City Challenge. See how your city is at risk and tell your own mayor to prepare!

Adapting to Climate Change

To avoid the worst consequences of climate change, we need to dramatically reduce the world’s carbon emissions. But we must also prepare for the significant changes in weather that the world is presently experiencing because of the pollution already in the atmosphere. Around the globe WWF works with local communities, governments and others to help nature and people successfully adapt to a changing climate. WWF prepares communities around the globe for climate change. To do this we:

  • Help communities in the Eastern Himalayas adapt to increasing water scarcity by collecting rainwater and promoting drought-resistant crops
  • Restore mangrove forests in Coastal East Africa to buffer shorelines from storm erosion
  • Protect coral reefs in the Coral Triangle to build their resilience against bleaching events
  • Identify areas where polar bears can live on solid Arctic sea ice for decades to come
  • Help farmers protect their crops from severe rainfall and droughts in the Amazon

Protecting Forests

Forests are home to many of the world’s most endangered wildlife. They also protect the planet by absorbing carbon dioxide (CO2), a major source of pollution that causes climate change. WWF fights climate change by saving forests. To do this we:

  • Ensure that global climate change agreements reduce forest destruction and degradation and protect wildlife
  • Work directly with countries, especially developing ones, to protect forests and benefit the livelihoods of local communities
  • Use satellite images and aerial mapping technologies to track illegal logging
  • Study the vulnerability of forests to climate change and explore ways to help them adapt

Government must play a central role to tackle the climate crisis. WWF is an advocate at all levels of government. In the United States, WWF works to advance policies that reduce carbon pollution, support clean energy technologies, prepare for the effects of climate change, and curb deforestation. At international negotiations, WWF encourages the United States to play a constructive role in developing global climate agreements that:

  • Substantially reduce carbon pollution to avoid the worst consequences of climate change
  • Provide financial support to developing countries so people and nature can successfully adapt
  • Combat forest destruction and protect wildlife that live there
  • Help transition developing countries to clean energy sources like wind and solar

Businesses have a responsibility to reduce their contribution to climate change. WWF works in partnership with companies as part of WWF’s Climate Savers Program to set and meet goals to reduce carbon emissions, advance projects to protect their resources from climate impacts, and ensure the sustainability of their core business.

Projects

  • Working with Coca-Cola to Improve Energy Efficiency and Reduce Emissions

    WWF and The Coca-Cola Company are working together to improve energy efficiency and reduce emissions in Coca-Cola's manufacturing operations, including those of over 300 independent bottlers. Together, WWF and Coca-Cola are working to achieve the company’s emissions reduction goals of growing the business, not the carbon, worldwide and reducing emissions five percent in developed countries.

  • WWF and The Coca-Cola Company Team Up to Protect Polar Bears

    WWF and The Coca-Cola Company are working to protect the Arctic. Building upon Coca-Cola’s support, since 2007, of WWF’s efforts to protect polar bears, together we are working to raise widespread awareness and funds to help protect the polar bear and its habitat.
