Question

So the real scientific debate is not about "whether" humans can change the climate (we can), its about 1) how much of the change is the fault of humans, and 2) is any of the effect reversible?
If humans are exacerbating the warming trend with fossil fuel consumption, can we slow down the trend by cutting back and using alternative fuels?Is changing the basis of our global economy worth the cost and effort, if it is even possible? Now that the economies of China, India, and others are growing, how will this affect the rate of CO2 input?

Climatologists predicted that man-made warming would produce a decrease in the differences between low nighttime temperatures and high daytime temperatures. And indeed, a decrease between day and night temperatures has been occurring in the america,china,Spain , and other regions. This phenomenon is global, although more recently daytime and nighttime temperatures have been increasing at about the same rate. Along with the observed increases in average temperature, heat waves have become more common since the 1950s.Humans change the climates ,human are many pollutents using thats so increasing the grean house gases.scintiscs warning for decades human actions pushed life“Episodes of global warming, ocean acidification and mass extinction have all happened before,

well before humans arrived on the planethumans have essentially become the top predator not only on land, but also across the sea, In doing so, humanity has begun using 25 to 40% of the planet’s net primary production for its own purposes. Moreover, we have added to this the use of fossil fuels for energy, essentially mining primary production from the past.

As human management of ecosystems and populations increases, even when aimed at conservation, evolutionary processes are altered.

I would argue that domesticated animals and plants, as well as humans, are parts of the technosphere,” said Haff. “These are in effect manufactured by the technosphere for its own use on the basis of genetic blueprints appropriated from the biosphere.”

CO2 is essential to plant life, and needs to be at least 150 ppm to sustain it. At higher levels, plant growth is enhanced – by some accounts doubling CO2 levels increases plant growth by about one-third  It cannot sensibly be called ‘pollution’ at any envisaged atmospheric levels.There remains considerable uncertainty regarding the above effects on the frequency and intensity of hurricanes, tornadoes and to some extent, droughts.

China and India. The two countries are by their sheer size economic giants and while they grow at the rates observed in recent years

In the country studies for China and India, analysis was undertaken using the Global Trade Analysis Project model and projections of future growth were made to the year 2020. Through this exercise the implications of rapid growth for production and consumption of agricultural products and trading opportunities for other countries in the region and the world have been assessed, based on certain assumptions.

air, water, soil, habitat destruction and biodiversity losses. Of particular concern to sustainability of agricultural growth and to food security are problems relating to misuse of land and water resources.

CO2 and other greenhouse gases continuously accumulate in the atmosphere, stabilizing or “freezing” emissions will not solve the problem. Greenhouse gases persist in the atmosphere for decades or even centuries, continuing to affect the climate of the entire planet long after they are emitted
