Although many processes are involved, clearly combustion of fossil fuels is the most important factor driving the global increase in atmospheric and thus global warming.

Temperature

Explanation:

Lots of CO2 is released from the combustion of fossil fuels and as CO2 is a greenhouse gas it is able to trap the solar radiation in the atmosphere which results in the increase in the atmospheric temperature and causing global warming.

Due to this global warming, the glaciers are melting very fast which is increasing the water level of oceans that can results in the tsunami.

The environment is changing fast due to global warming. This is affecting animals, plants, and humans too. Habitat of animals living in the polar areas affected severely due to the increase in global temperature.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
