What are some immediate ways I can take action?

Here are some fast and simple actions you can take to help shape Boston’s climate future!

Get connected:  Sign up for Greenovate’s newsletter for up-to-date information, programs, and even financial incentives that help Bostonians address climate change.

Join the conversation: Greenovate’s discussion boards and Facebook page invite you to share your ideas for making Boston greener. Great climate conversations are happening on other Facebook pages too, including Climate Nexus, I Heart Climate Scientists, and Earth-The Operators’ Manual.

Take a step: Many sites such as Greenovate and Earth-The Operators’ Manual suggest personal actions for reducing your contribution to greenhouse gas emissions. On this site, look under “How else can I take action?” for our suggestions.

Get involved: Give your time to state and city programs that rely on volunteers to help make Boston more sustainable.

How else can I take action?

Reducing our energy use is the best way to reduce our contribution to greenhouse gas emissions and minimize the impacts of climate change. We can all be climate leaders by choosing our purchases, activities, and elected officials carefully! To start, Greenovate Boston has a comprehensive array of resources for climate-friendly (and budget-friendly) living.

The following resources show actions we can take in our homes, our transportation, and our communities.

How are humans affecting the climate?

When scientists discuss climate and human activity, they are usually referring to what happens when people burn fossil fuels for transportation, electricity, and industrial uses. They provide the energy that we use to warm our houses, turn on light bulbs, make cars go, etc. It takes millions of years for the carbon from ancient organisms to become fossil fuels, but burning them gives off carbon dioxide, water, and other by-products and greenhouse gases in seconds.

What is the evidence that humans affect the climate?

Scientists agree about human-caused climate change because it is the best way to make sense of the evidence and observations made over the last century. Thousands of independent scientists have considered other explanations such as solar output or volcanic eruptions for the increase in global temperatures, but these theories do not account for all the evidence collected.

Scientists have additionally observed changes in the past century—such as higher amounts of CO2 in the air, rising sea levels, quickly melting glaciers, and higher average surface temperatures on Earth.

Indeed, the Earth goes through natural cycles. Ocean currents, such as El Niño or La Niña, volcanic eruptions and changes in radiation from the sun can affect the Earth’s weather patterns for a given amount of time, generally within the span of a few years. But the sustained, nearly century-long patterns of higher carbon dioxide count in the atmosphere, surface temperature, sea levels, and glacier melt have pointed to something tied inextricably to our burning of fossil fuels over the last 150 years.

Who are climate scientists?

Climate scientists can have a wide range of specialties in fields such as earth sciences, chemistry, biology, physics, or computer science. Their studies are not limited to the small scale of weather, which describes local conditions over the short time span of a few days. Climate scientists think big, studying complex systems over long time spans of at least 30 years, and in some cases hundreds or thousands of years.

Climate science is challenging to study because it is measured all over the globe, over long periods of time, and is affected by many factors. Scientists investigate aspects of oceanography, geology, paleontology, and chemistry. For example, they might look at the rings of trees or ancient ice cores to find clues about our past climate. They also study human-recorded weather data over long periods of time. Analyzing these clues, scientists can create models to make mathematical predictions about what may happen in the future.

What causes climate change?

Many different factors cause climate to shift. Changes in ocean circulation, life on Earth, gases in the atmosphere, changes in the sun’s radiation, and geological activity such as volcanic eruptions and plate tectonic movement can all affect the climate. Some of these changes occur naturally and happen over hundreds, thousands, or millions of years, while others are caused by human activity and occur over centuries or decades.

When did human-caused climate change begin?

Human beings began using fossil fuels that emit greenhouse gases a few centuries ago, and scientists were able to make the first climate change predictions all the way back in the 19th century. However, it has been in the last 50 years that carbon dioxide in our atmosphere has risen most severely. Like the glass in a greenhouse, carbon dioxide (along with water vapor, methane, and nitrous oxide) allows light from the Sun to reach Earth while preventing the Earth’s heat from radiating back out into space. Without these greenhouse gases, our planet would be cold and unlivable. While changes in atmospheric gases occur naturally over long periods of time, scientists are concerned that the recent increase of carbon dioxide in the atmosphere could have unpredictable effects.

Where is climate change happening?

Climate change is a global problem, but different places will experience different outcomes of climate change. While sea level rise, changes in precipitation, and warmer seasons are in Boston’s future, much of the American southwest, for instance, will experience more problems with drought and water scarcity.
