Half of the Great Barrier Reef has died since 2016 and scientists say it's a direct result of climate change.
Coral lives in a symbiotic relationship with algae. Algae converts energy from the sun into food that feeds and nourishes the coral. When water temperatures rise the algae vacates, causing the coral to 'bleach' and eventually die. The results can be devastating. The bleaching spreads across miles of reef, transforming once spectacular ecosystems into barren wastelands.See Stock Images of the Reef
"People often ask me, will we have a Great Barrier Reef in 50 years or 100 years?" says Terry Hughes, the director of the ARC Center of Excellence for Coral Reef Studies. "And my answer is, yes, I certainly hope so – but it's completely contingent on the near-future trajectory of greenhouse-gas emissions."

In the news: "A 3.8 Billion-Pixel Tour of Mount Everest" by Claire O'Neill NPR SC5980 Mount Everest, seen from the International Space Station (ISS).
The view is tilted about 45 degrees clockwise and looks to the
south-west. Everest (8850 metres, centre, largest shadow) is brightly
lit in the early morning sun. The low-angled light makes the mountains
stand out from their shadows. This is Everest's eastern side, the
Kangshang Face. The North Ridge, a popular climbing route, runs down to
lower centre. In front of Everest, a large glacier (grey) winds
downhill. Everest is on the border between China (lower left) and Nepal
(upper right). The ISS orbits around 380 kilometres above the Earth.
