MIT Alumni for Climate Action Home Page
The MIT Alumni for Climate Action (aka MACA) is a non-partisan group of Massachusetts Institute of Technology alumni concerned about the devastating effects of climate
change. We support action at all levels to communicate the urgency of
the problem and reduce the risk and damage from climate change. We
support science based interventions in the energy, transportation, industry, and agriculture systems such as the rapid development of renewable wind and solar
energy capability and elimination of fossil fuel usage to drastically
reduce carbon dioxide and other greenhouse gas emissions.
Human activities have increased the concentration of carbon dioxide in our atmosphere to over 400 parts per million (ppm), which is higher than at any point during human history (upper Figure). The last time carbon dioxide was this high was >3 million years ago, when the temperature was 2°-3°C higher and the sea level was 15-25 meters higher than today. Carbon dioxide is increasing due to the burning of fossil fuels, greatly amplifying Earth's natural greenhouse effect, and leading to global temperature rise (lower Figure), warming oceans, melting polar ice, glacial retreat, sea level rise, extreme weather events, and ocean acidification, commonly referred to in aggregate as climate change.
The United Nations Intergovernmental Panel on Climate Change (IPCC) assessments have detailed the far-reaching and unprecedented responses required. The international community of nations responded with the Paris Agreement in 2015. Limiting carbon emissions immediately, through reduction in our carbon footprint, will lead to lessening
global warming, and ensure a more sustainable world with clear benefits to people and natural ecosystems. The longer we wait to act, the more difficult the problems will be to address in future. Our immediate goal must be to reduce carbon emissions by 50 % in the next decade followed by their elimination within a generation.
As our first action, a group of MIT alumni in Maryland sent an open
letter on climate change to all candidates running for public office in
the State in October 2018. The letter was signed by more than 100 alumni and sounded the
alarm bell on the effects of climate change. The letter was supported by US Senators and Congressmen, and State Senators and Delegates, and helped support the Clean Energy Jobs Bill in the state. The group also
provided background information on climate change and its
effects on the State, which is particularly vulnerable and is exposed to
dire consequences because of its long coastline and potential for
flooding from increasing severity and frequency of storms and sea level
rise. They included links to tools, resources, and references on
climate change and energy generation for Maryland's leaders as well as
all concerned citizens. These links, including details on our initiative in Maryland, are available from our Web Portal.
Additional climate actions of MIT alumni are in progress for 2020. For more information, see our Mission and Action Plan, which is also available from our Inside MACA page, sign up to join the MACA Team, or follow the group on Twitter.
The MIT Alumni for Climate Action group is a member of the MIT Alumni Energy, Environment, and Sustainability Network (EESN) and the MIT Climate community.
