How is climate change affecting sea turtles?
Now, climate change is exposing sea turtles to even greater existential threats. Sea level rise and stronger storms will erode and destroy their beach habitats. Warming oceans will change ocean currents, potentially introducing sea turtles to new predators and harming the coral reefs some of them need to survive.
How has climate change affect turtles?
Weather extremes, also linked to climate change, mean more frequent and severe storms which alter nesting beaches, cause beach erosion, and inundate, or flood sea turtle nests. Hotter sand from increasing temperatures results in decreased hatching rates or complete nest failure.
How does air temperature affect sea turtles?
One of the major effects of climate change is an increase in air temperature, which correlates to an increase in sea surface temperature. Since sea turtles lay eggs on beaches, the hotter sand leads to less ideal conditions for laying eggs, which leads to decreased reproductive output.
What climate does a sea turtle live in?
Sea turtles live in almost every ocean basin throughout the world, nesting on tropical and subtropical beaches. They migrate long distances to feed, often crossing entire oceans. Some loggerheads nest in Japan and migrate to Baja California Sur, Mexico to forage before returning home again.

Can a person live to be 200 years old?
Professor Stuart Kim has now raised the maximum age from 150 to 200 years. But he has a problem. The world record of 122 years was set by Jeanne Calment, and has stood since 1997. Sponges and corals are known to live for thousands of years, while some sharks, and whales, can reach an age of over 200 years.

What kills you when you die of old age?
With old age there is loss of some of the stem cells. This is particularly devastating in the bone marrow that has had a high turnover of cells all during their lives. But without enough blood cells there can be bleeding from a lack of platelets, serious infections from a lack of granulocytes and lymphocytes.
Do we age in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
