Human-Induced Climate Change – the winners and losers

I discussed the cost of human-induced climate change with Dr Rucha Karkarey, a coral reef ecologist and marine conservation biologist from India. She has been studying how habitat loss from climate change impacts the diversity and functioning of coral reef fishes.

Her work has been based in the lesser known Lakshadweep archipelago in India, which incidentally is part of the same island chain as the popularly known Maldives and Chagos (in other words, a gorgeous, gorgeous place!).

Dr Karkarey diving with the tropical fish around Lakshadweep.
“I love being out there on the boat, sipping on copious amount of black tea and pondering life, when I don’t have my head in the water following fish.”

Through her work, Rucha explores the losers and winners in this era of climate change.

How the winners are winning (some fish are coping with habitat loss better than others) and what potential roles and benefits these winners can play in degraded and altered coral reefs.

The rhetoric around climate change is (rightly) rather gloomy: we are losing biodiversity at an unprecedented rate, with consequences for entire ecosystems and the people they contribute to.
