Scientists can estimate the atmospheric absorption of emissions by measuring CO2 in gigatons and predict how much the Earth’s temperature will rise, including the potential for surpassing a 1.5°C increase. If emissions remain constant, “the budget would be expected to be used up in less than eight years” (mcc-Berlin). While having a proposed timeline is useful, various factors—such as global events like the pandemic—can either accelerate or decelerate the rate of warming.

The En-ROADS team at MIT has developed a simulator that predicts climate scenarios based on real-world data across key sectors. The simulator models dynamics in energy, transport, buildings and industry, land and food systems, integrating policies and the best available information to track potential outcomes.

Modern societies have been aware of climate issues for decades, yet we’ve struggled to make sufficient collective changes. However, many practical strategies are available today to help save, preserve, and remediate Earth’s ecosystems. One critical opportunity lies in conserving remaining intact terrestrial ecosystems. Individuals and organizations can take action by advocating for stronger governance, influencing policy, and facilitating the necessary changes that will shape the planet’s future. For specific actions and a timeline, check out the roadmap provided by Project Drawdown via the link below.

Earth’s natural systems have an incredible ability to rebound when restorative or regenerative practices are applied. These practices—including reintroducing apex predators, re-wilding ecosystems, and reducing destructive impacts—help restore balance. Nature itself also has the capacity to sequester more carbon, further aiding in climate mitigation. There are numerous proven ways to address climate change, but they need support and investment.

One critical point that is often overlooked is the compounding benefits of acting quickly. Reducing greenhouse gas emissions now leads to exponential savings in the long run, helping us avoid tipping points that could trigger irreversible damage. The time to push for comprehensive, immediate action is now.
