Between 1982 and 1999, the climate became warmer, wetter, and sunnier in many parts of the world. Nearly 20 years of satellite observations of Earth’s vegetation reveal that these changes increased the overall productivity of land plants by 6 percent. This map shows productivity increases during the time period in green, while decreases are shown in brown. Productivity, which is the net uptake of carbon, increased the most in tropical regions and northern latitudes. In the tropics, climate change resulted in fewer clouds and more sunlight, while in the North, temperatures increased. Productivity increased as climate change eased the normal constraints on plant growth in a given region.
Dear Prof, I am sad to say it but many developing countries including my country 'lost' a lot of its forests from the 1970s - 1990s, and the cities took on a concrete jungle appearance. That was a way to express it , without blaming people, but the persons who managed the country were responsible, and we citizens too, for not having power to speak and make a difference!
"(Redacted) second infamous letter was sent in 1987, to 10-year-old Darrel Abercrombie, who was concerned about deforestation and the environment. The English schoolboy had written to request the (Redacted) to stop logging activities in Malaysia, because "he wanted to study animals in the tropical rainforests when he grew up".
(Redacted)'s response was a three-page typed document criticising Darrel for agreeing to be used as a pawn, by adults. He said “The timber industry helps hundreds of thousands of poor Malaysians. Are they supposed to remain poor because you want to study tropical animals? Is your study more important than filling the stomachs of poor people? Are Malaysians expected to lose millions of pounds so that you can study animals?"
I thought the human responsability in global warming was an established fact. Maybe you are really asking how not why?!
Professor Anastasios Tsonis, of the University of Wisconsin, said: "We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped.”

Really, population growth, deforestation, etc...Dangerous situation.
I would answer by saying the earth can sustain as much as the environment can accommodate. I think the earth is full, there are disasters that happen, man made or otherwise. So the answer from Google is 10 billion...there is cause and effect

To my knowledge, the Earth is getting warmer and warmer and seems to be a consensus among most scientists that human activity has something to do with that.
Most countries have signed an agreement that seeks to "avoid catastrophic climate change by limiting warming to 1.5C to 2C", points out The Guardian.

This last March was the hottest ever worldwide, so the heat continues.
As Jose said, if human activities have something to do with a warmer earth, wouldn't people think of changing activities so as to minimize this warming? There are lots of suggestions, but no universal plan of action.
Read the book Rain by Cynthia Barnett, this gives a good explanation about global warming.
sure basically, the earth changes on constant basis, we are not the cause of global worming. There are shifts in rain that have happened over the past 100 years that have been recorded. El Nino is the current cause of California's problem. Basically the researchers are reluctant to say that climate change is a human cause. Acid rain is a problem because of soot but every time you try and manipulate water, there are drastic consequences. We are not responsible for global warming per se but the earth is getting warmer but it is climate change not any human influence. The earth will adjust to its temperatures, it always will. The more you control rain, the more out of control it gets. That is the basic gist of the argument being made in rain. Weather is its on own entity, there are many factors that need to be considered.
dear all
in our country the temperture till now inceasing year by year and the period of summer increased also
The claim of a pause in temperature increase since 1998 is difficult to support in any official data such as these very current ones showing the average temperature in the mentioned 48 states and the world .
The majority of researchers and other persons with an interest in this believe that the temperature increase which is still ongoing is due to increased concentrations of gasses in the atmosphere which absorb infrared radiation, CO2, CH4 and N2O, the greenhouse effect.

Another fantastic case of cherry picking: By selecting the record warm year of 1998 to start the trend calculation the immediately following year seems to be in a cooling or stagnant trend. This is dishonest because we know from the variation in the years before that 1998 was an extremely hot year that deviated far from the normal or much slower heating trend. If 1997 was included in the analysis the trend would go the other way which shows that cherry picking is able to dishonestly claiming the opposite of that the data show.
Another way to see the data is that 1998 was the warmest year in the first 100 y temperature has been recorded in the NOAA dataset. Still during the claimed (by Kenneth) cooling trend until the present 3 years are even hotter while each and every year are hotter than the clima normal (average for the first 100 y).
