Sometime in September 2016, scientists from all over the world warned that Earth had passed a tipping point for carbon dioxide (CO2) concentration in the atmosphere. This means that the atmosphere has reached an irreversible warming milestone.
Even if every human on Earth stopped using electricity altogether, scientists stress that there is no way that the CO2 levels in the atmosphere will dip below 400 parts per million. The year 2016 also burned through heat records, causing the longest and hottest dry spells in history. And yet, despite the temperature monitoring tools being highly modernized and accurate, the denial surrounding manmade climate change has become even stronger.
Tracking Earth’s Vital Signs
Satellite technology is not used only for satellite navigation or GPS. Systems are also in place to monitor climate data in real time and present virtual simulations. Climate change deniers claim that humans and industries have nothing to do with the warming data that scientists have. They add that global warming is a natural phenomenon, the planet’s way of renewing itself and that humans have no control over it.
To strengthen the evidence for anthropogenic climate change, scientists at NASA and other institutions have developed different tools and models to monitor human influences on the environment. Weather data has since significantly expanded. Scientists can monitor human emissions down to the smallest and largest scales and their direct effects on global temperature and microclimates.
Simulated Climate Evolution
As satellite constellations become progressively more sophisticated, scientists can create simulations of the atmosphere and almost every conceivable aspect of the planet, all in pursuit of rooting out the actual source of climate change.
Scientists at NASA have created satellite maps that show temperature shifts in the troposphere and stratosphere. People can access these maps via NASA’s and government websites. These climate model simulations reveal climate patterns in line with the increase in human emissions. They also quantify and differentiate anthropogenic climate change with natural climate noise, such as emissions from volcanic eruptions.
Manmade climate data is as precise as it can get. But scientists have a bigger battle to win here on Earth, and that is to advance the truth amidst vehement climate change denial.
