NASA Launches Satellite to Watch Earth Breathe From Space
In an effort to understand how climate change is altering the carbon cycle, a project between the University of Oklahoma and NASA is headed to space. Orbiting 22,000 miles above Earth's surface, this host of instruments will track carbon as it flows through the Earth delivering real-time data and helping scientists quantify just how much humans are affecting the planet.
The carbon cycle is an inconspicuous, but vital, system in all ecosystems, including marine habitats, forests and even deserts. All plants need carbon to complete photosynthesis, and when they die, that carbon is either released back into the atmosphere, or buried deep under ground to create fossil fuels over thousands of years. As we are seeing today, the carbon cycle plays a huge role in temperature fluctuation and weather patterns and unfortunately, the more carbon we trap in the atmosphere, the more unpredictable these fluctuations become.
The University of Oklahoma is calling the mission the Earth Venture Mission, and the payload (the part that will attach to one of Earth's satellites) is called the Geostationary Carbon Observatory, or GeoCarb. Although it may seem like an extreme measure to take, scientists believe it is necessary. The increase of carbon in the atmosphere well surpassed the point of no return—or carbon threshold—in 2016 and has continued to steadily rise above 400 parts per million. This is rapid warming compared to the 280 ppm that persisted for thousands of years before the industrial revolution. Scientists say we've reached a state of unknown, and launching the GeoCarb is our best bet in being able to predict where we go from here.

The GeoCarb will rotate in tandem with Earth at 85 degrees west longitude where it will be able to record human activity in developed nations from urbanized areas to agricultural lands. It will take measurements of carbon dioxide, methane and carbon monoxide once or even twice daily. It will also measure solar induced fluorescence, which is the light that plants can't absorb and is therefore repelled from Earth. This measurement will be closely tied to the rate of photosynthesis, and will help map out where carbon sinks exist. The map will also help scientists understand where there is a natural release in carbon, such as when a plant dies and decays, versus when human-induced carbon is released. It will be the first time scientists are able to watch the Western Hemisphere breathe in and out every day.
"Knowing what fraction of these changes is caused by human activities is important for understanding our impact on the planet, and observing and measuring it is essential to any conversation about strategies for reducing CO2 emissions," Berrien Moore, director of the National Weather Center at the University of Oklahoma, told The Conversation.
"These observations, along with direct measurements of photosynthetic activity from SIF observations, will raise our understanding of the carbon cycle to a new level."

Calling the global climate crisis both the greatest threat facing the U.S. and the greatest opportunity for transformative change, Sen. Bernie Sanders unveiled today a comprehensive Green New Deal proposal that would transition the U.S. economy to 100 percent renewable energy and create 20 million well-paying union jobs over a decade.
The Parties to CITES agreed to list giraffes on Appendix II of the Convention on International Trade in Endangered Species (CITES) today at the World Wildlife Conference or CoP18 in Geneva. Such protections will ensure that all giraffe parts trade were legally acquired and not sourced from the poached giraffes trade and will require countries to make non-detriment findings before allowing giraffe exports. The listing will also enable the collection of international trade data for giraffes that might justify greater protections at both CITES and other venues in the future.

The UN's health agency on Thursday said that microplastics contained in drinking water posed a "low" risk at their current levels.
However, the World Health Organization (WHO) — in its first report on the potential health risks of microplastic ingestion — also stressed more research was needed to reassure consumers.

'Work Together' or 'Destroy it': Goldman Prize Winner Francia Márquez on World's Second Deadliest Country For Environmental Activists
In April 2018, Afro-Colombian activist Francia Márquez won the prestigious Goldman Environmental Prize, thanks to her work to retake her community's ancestral territories from illegal gold mining. However, her international recognition comes at a very risky price.

A year after activist Greta Thunberg first stood in the rain outside the Swedish parliament with her now iconic "Skolstrejk för klimatet" — school strike for the climate — placard, the movement she spawned has set the tone for environmental protest action around the world.
