Earth’s climate has changed before. For example, about 20,000 years ago, there was an Ice Age during which much of North America was covered in ice. What makes global climate change today different from previous changes like the one mentioned above?

thermophiles, notice the prefix thermo.

the most logical answer would be a

blah

explanation: bc blah

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
