Marketing can play an important role in this, through developing products and services that have a low carbon footprint—the climate impact measured in carbon dioxide equivalent (CO2eq) emissions. In 1958, the CO2 concentration in the atmosphere was measured at 316ppm, as of May 2016 it was 407ppm. These emissions are known as a “carbon footprint, and the larger a carbon footprint, the larger the contribution to climate change.” (These days, the term “carbon footprint” is used as a catchall phrase for all the climate-change-causing greenhouse gases, not just carbon dioxide or other carbon derivatives.) In other words, climate change includes major changes in temperature, precipitation, or wind patterns that occur over several decades or longer. First, you can recycle, use less electricity and use public transportation. http://climate.nasa.gov/ - Contains insightful infographics, recent news stories on climate change and explains how NASA is collecting data relating to Climate Change. Climate change food calculator: What's your diet's carbon footprint? Currently electricity and transport represent the largest sources of emissions and greatest opportunity for saving. But the truth is that the method you choose to dispose of your mortal remains has more of a deleterious impact on the environment than you might think. Tamara Reháčková, PhD. Although reducing energy use is today’s latest rage, a measure of your carbon footprint will also include recycling. A carbon footprint is basically the total amount of greenhouse gas emissions that anything -- a person, organization, event or product -- has produced. Climate change has impact on carbon cycles. The warmer ocean surface temperatures impact corals and alter coral reef communities by prompting coral bleaching events and altering ocean chemistry. Carbon emissions from burning fossil fuel accumulate in the atmosphere if there is not enough biocapacity dedicated to absorb these emissions. In 2014, The Intergovernmental Panel on Climate Change (IPPC) published the 5th Assessment report on climate change based on long-term scientific evidence. In addition, Carbon Footprint points out that when you recycle, your garbage takes up less room in landfills. The Carbon Footprint The carbon component of the Ecological Footprint—which we call the carbon Footprint—measures the area of forestland that is required to absorb all the carbon emissions from human activity in excess of what the oceans already absorb (the carbon Footprint can also be expressed in tonnes of CO2 emitted). Yes. The United Nations estimates that the annual carbon footprint of global food waste is 4.4 gigatons of CO 2 equivalent. Change in El Nino intensity (As El Nino intensity is in part based on sea surface temperatures, rising temperatures will cause more intense El Ninos causing flooding, droughts, wild fires and famines.
