The solar radiation affects the earth’s planetary ecosystem by changing the climate that these ecosystems live in. With the solar radiation being able to penetrate through the atmosphere it increases tropospheric warming. These sudden climate shifts are impacting certain types of species and plant. Time's Gateways - how have the past shifts in climate influenced the planet? How can our present time period cause the same kind of dramatic shift (i.e., what are Humans doing to cause a time gateway)? In the section Time’s Gateway “the three agents of change sufficiently powerful to open a gateway in time—the shifting of continents, cosmic collisions, and climate changes.” Some past shifts in climate being the great ice age, the big bang meteor, and the shifting of the lands. Another dramatic shift or “time gateway” can be formed by humans because with our week atmosphere and ozone it makes the planet more vulnerable to change. Born in the Deep Freeze - why are Humans and so many animal and plant species today threatened by global warming? Humans and so many animal and plant species today are threatened by global warming for many reasons. Mainly because all humans, animals, and plants are interconnected; for example, when the earth is too hot many of the animals and plants begin to die off. Those plants and animals that die off due to heat cause the humans to find plant and animal food sources elsewhere. Also, insects that carry diseases are living longer because of the temperature rise which gives them more time to infect their surrounding counterparts. The Long Summer - how has human activity in the past interacted with climate patterns to produce the "long summer"? If Human activity in the past has influenced the Earth's climate (we are part of Gaia), how might we do it again?
Human activities in the past have interacted with climate patterns to produce the “long summer” by agriculture techniques and the industrial revolutions. These activities aided in the long 8,000 yearlong summers. However, humans today continue to add years to this long summer by building more cars,
