Scientists have noted that at present the Earth is closest to the Sun in January and farthest from the Sun in July. The reverse will be true in 13,000 years and the Earth
will then be closer to the Sun in July than January. How would this change affect the
climate in the Northern
Hemisphere?

1.)Winters would be cooler and summers warmer because of the closer proximity
of the Earth to the Sun.

2.Winters would be longer and summers shorter because of the closer proximity of
the Earth to the Sun.

3.Winters would be shorter and summers longer because of the closer proximity of
the Earth to the Sun.

4.Winters would be warmer and summers cooler because of the closer proximity
of the Earth to the Sun.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
