NASA and Climate change
The National Aeronautics and Space Administration ( or NASA) are pretty famous for their Apollo missions, but there have been several other missions carried out by them that are sending back data that supports climate change. In this blog post I'm going to be focusing on proving global warming with some cold, hard facts from the starman in the sky.
The graph above shows us CO2 readings up to the 1950s where the Carbon dioxide levels spiked. The highest reading changed from 300 parts per million, which was recorded around 350,000 years before 1950, to nearly 420 parts per million. Parts per million meaning if there are one million particles in the air, 420 of said particles would be CO2.
I realise, that in the time span of 350,000 years a 120 parts per million increase doesn't seem completely unreasonable. But, you have to understand that 300 was the maximum for almost a millennia so for the carbon dioxide levels to rise above that was extraordinary, well extraordinarily bad.
Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.
Sentinel-6 Michael Freilich Mission
On November 10th, the world's latest Earth-observing satellite will launch from Vandenberg Air Force Base in California. Why is this satellite so important?
The Sentinel-6 Michael Freilich spacecraft will begin a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change.
The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models. In 2025, Sentinel-6 Michael Freilich's twin, Sentinel-6B, is scheduled to launch and advance these measurements for at least another half decade.
The name might be a mouthful, but it'll be worth it once we get the incredible data promised by this mission. Here's a video explaining it further.
