The world’s climate is changing, and these changes will have an enormous impact on our planet, especially our ocean.

By taking action now to ensure a healthy ocean and healthy marine mammals, we are also protecting future generations of marine mammals and people from the anticipated effects as climate change accelerates in the coming years.

What is global warming?

The burning of fossil fuels like coal, oil and natural gas is causing an increase in carbon dioxide in the atmosphere. This traps the heat of the planet like a blanket causing the oceans, land and atmosphere to warm.

What's Happening?

You may be wondering ...

What exactly is climate, and how is it different from weather?

Plus icon Minus icon

Weather refers to short-term atmospheric conditions and what we see on a day-to-day basis. If you say, “it’s currently raining outside,” you’re talking about the weather. Climate refers to conditions over a longer period of time – typically a 30-year average. 

Different variables make up our climate, including precipitation and temperature. Climate describes what conditions we can usually expect in a certain region. If you say, “it usually rains in Seattle,” you’re talking about climate.

What is the difference between climate change and global warming?

Plus icon Minus icon

The two terms are similar, and they are sometimes used interchangeably. Global warming describes a more specific aspect of climate change: an overall increase in the Earth's average temperature. 

Climate change is a broader term though. It refers to any change we will see in climate over an extended period of time, including changes in precipitation or even the intensity of storms. Climate change can also be used to describe changes on a regional or global scale. 

What is making the Earth warmer?

Throughout history, different gases have kept the Earth at a temperature where life as we know it can survive. These gases, such as carbon dioxide, water vapor and methane, act as a big heat-trapping blanket over Earth's atmosphere. 

Similar to the way a blanket works, these gases let in light and heat and keep this heat at the Earth's surface. As radiation from the sun reaches Earth, these gases keep in some heat while the rest goes back out to space.

However, as we've burned fossil fuels like coal and oil for daily human activities, even more of these heat-trapping gases are being released into the atmosphere. This rampant carbon dioxide has added to the heat trapping blanket, keeping more heat at Earth's surface. Since 1950, we have seen the amount of carbon dioxide in the atmosphere increase by 30 percent!

Why is carbon dioxide so important?

Plus icon Minus icon

Carbon dioxide is the main greenhouse gas released by burning fossil fuels like coal, oil and natural gas. It stays in the atmosphere for a long time, and it has the ability to trap in a lot of heat. 

Before we used fossil fuels for most of our daily activities, the concentration of carbon dioxide in the atmosphere was relatively low. Today, carbon dioxide concentrations have reached unsafe levels that we haven’t seen in the past 800,000 years!

How does the ocean affect climate?

Plus icon Minus icon

The ocean is the base for all life on the planet. The ocean absorbs most of the heat coming from the sun. The ocean also acts like the climate’s heart, circulating warm water in the tropics to colder regions, and cold water from the poles to warmer regions. 

This distributes heat and corrects the uneven distribution of radiation reaching Earth. Without currents, temperatures in the poles would be even colder and temperatures in the tropics would be even warmer.

Is there a connection between human activity and climate change?

Plus icon Minus icon

While natural processes can change Earth’s climate, human activities are changing climate more rapidly than ever seen before. Industrial activities have raised carbon dioxide concentrations higher than ever seen before in 800,000 years, and increases in carbon dioxide closely coincide with increases in temperature. 

The rapid changes we are seeing today also closely coincide with the start of the Industrial Revolution when we first began burning fossil fuels like coal in large amounts for daily activities, like driving cars and using electricity.

Is there a lot of scientific debate about climate change?

Plus icon Minus icon

Over 97 percent of climate scientists agree that climate change is happening, faster than ever before, and that humans are causing many of the changes due to things like burning fossil fuels. The only question remaining is what communities and countries will do in the coming years to cut carbon emissions.

How has climate changed in the past? How may it change in the future?

Plus icon Minus icon

The Earth’s climate has changed throughout history from natural processes. Atmospheric samples from hundreds of thousands of years ago trapped in ice cores have indicated that the planet has undergone many periods of freezing and warming. Typically, these changes occur over long periods of time stretching thousands of years. 

Today, we are seeing rapid changes at a faster rate than ever before, whether it is sea level rise of 6.7 inches over the last century or record-setting global temperatures the last few years. 

Future change will depend on many factors, but the most important factor is how much fossil fuels are burned by communities around the world. Depending on our emissions, temperatures could increase by about 2.5 to 10 degrees Fahrenheit by 2100, dramatically altering the environment as we know it.

How might I be affected by climate change?

Plus icon Minus icon

Global climate change will affect every aspect of our lives. Events like drought, severe storms and heat waves will have a direct impact on human health, water and food supply. Other things that we value, such as unique biodiversity and spots for recreation, will also be at risk.

Is it too late?

Plus icon Minus icon

The Earth is nearing a tipping point, but it has not passed that point yet. Certain sensitive ecosystems, like some coral reefs, that have already been damaged by climate change may not recover or may take a long time to recover. 

It’s important that we make a commitment to act quickly to give ecosystems a fighting chance. Carbon dioxide and methane linger in the atmosphere for extended periods of time, so we must take action now to prevent future changes.

How You Can Help

You can take action in your daily life and community to reduce your carbon footprint. Not only will you help protect the environment, but many solutions can also help you save money.

Taking Action at The Marine Mammal Center

Solar Panels and Renewable Energy

The solar panels over the patient pens and medical buildings generate between 25 to 35 percent of our energy consumption. While our filtration is quite energy-intensive in order to provide the best care for our patients, each year our our solar panels collect the equivalent of what it takes to power more than eight average homes.

Because it is cheaper to use solar energy rather than fossil fuels in California, we are also able to save close to $20,000 a year, meaning that your donation dollars can go farther in supporting our patient care and education work.

A local Community Choice Aggregation called MCE provides solar and wind energy to cover our remaining energy use, which means the Center is powered on 100 percent renewable energy.

Water Conservation

Clean water is critical for our patients, but we are mindful of our water usage at the hospital. Utilizing a state-of-the-art filtration system, we are able to recycle 80 percent of the water in the patient pens and treat it with ozone gas in order to ensure that our patients have a clean environment for healing without wasting precious water resources.
