“We see evidence that lakes and forests and wetlands can have different equilibria — so you have a savanna system that may be stable and thriving, but it can also tip over and become an arid steppe if pushed too far by warming, land degradation and biodiversity loss. A clear-water lake can become a murky, biodiversity-low anoxic lake. Unfortunately, the science is increasingly showing that even large systems can tip.”

<p>Eu não vi o mar.
Não sei se o mar é bonito.
Não sei se ele é bravo.
O mar não me importa.</p><p>Eu vi a lagoa.
A lagoa, sim.
A lagoa é grande
e calma também.</p><p>Na chuva de cores
da tarde que explode,
a lagoa brilha.
A lagoa se pinta
de todas as cores.
Eu não vi o mar.
Eu vi a lagoa...</p>

"The Abyss"
The Far Field (1964)
Context: A terrible violence of creation,
A flash into the burning heart of the abominable;
Yet if we wait, unafraid, beyond the fearful instant,
The burning lake turns into a forest pool,
The fire subsides into rings of water,
A sunlit silence.
