500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess).
Climate change and the associated warming of the ocean will lead to widespread changes to the Earth's climate and weather system including increased tropical cyclone and monsoon intensities and weather extremes with some areas becoming wetter and others drier. [14] Changing wind patterns are predicted to increase wave heights in some areas.
It bursts and floods out through the Mackenzie River into the Arctic Ocean at 11,000 BC, possibly causing the Younger Dryas cold period. c. 12,000 BC c. 8,000 BC Göbekli Tepe, world's earliest known temple-like structure, is created. c. 10,800 BC Younger Dryas impact event is proposed to have occurred, causing the onset of the Younger Dryas.
It notes that land-use change – which includes clearing land for agriculture or urban development – is the biggest current threat to nature, but adds that climate change is “likely to become ...

[49] [50] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of internal ocean temperature".
A new United Nations report says climate change poses major threats to people and ecosystems around the world, and warns that effects could be catastrophic if humanity fails to quickly curb planet ...
In addition, climate change impacts oceanic currents and sea levels, further altering fish distributions and habitats. Furthermore, ocean acidification , resulting from increased CO2 levels, compromises the ability of shellfish and corals to form shells and skeletons, further endangering marine ecosystems and the communities that depend on them.
