Janet Sewell of Aiken jogs on Riverwalk Augusta. A climatologist says Georgia has had a small cooling trend since 1998, but models predict further warming.

Georgia got cooler through much of the 20th century, but since about 1970, it’s been getting warmer like the rest of the globe, says University of Georgia climatologist Pam Knox, a former assistant state climatologist.

While the state is getting about the same amount of rain and snow that fell on Geor­gia a century ago, the way it’s falling is changing, she said at a campus symposium on climate change last week.

“It’s more likely to be in high-intensity bursts now,” she said.

In between those flood-producing downpours, the state is getting more drought, she said.

Gov. Nathan Deal fired Knox and state Climatologist David Stooksbury in Septem­ber, replacing them with a meteorologist in the state En­viron­mental Protection Division.

Like much of the nation, Georgia was very hot and dry in the 1930s and 1940s, due somewhat to fewer volcanoes erupting around the world, Knox said. Volcanic
particles help to reflect the sun’s energy back into space.

But from then until around 1970 or so, the state’s average temperature cooled – at least in part because of a big change in land cover, Knox said.

Georgia lost much of its forest cover in the late 19th and early 20th century, cut down for timber or cleared for cotton fields.

Through much of the middle and late 20th century, the amount of forest in Georgia increased, and now the
state is about 70 percent forest.

Since about 1970, rising temperatures in Georgia have matched rising global temperatures – except for the period from 1998 to now, a small cooling trend.

Knox expects Georgia to keep warming in the immediate future, however.

“Most models agree that temperatures will increase. How much is another question, and how
much at day and at night,” she said.

I'm curious why Gov Deal

I'm curious why Gov Deal fired Knox and state Climatologist David Stooksbury, and who the person is that replaced them, and why that person.

Also, good job AC for writing and promoting science, and global change.

So Knox was fired from one

So Knox was fired from one state job, but now she's the "climatologist" for UGA, so she's still on the state payroll. The article doesn't say where Stooksbury is.

I pointed out the reality of man-made global warming (climate change) on The Augusta Chronicle bulletin board "The Forums" as early as July 2003. My position was pooh poohed by climate change deniers over the years despite increasing certainty by the scientific community. AFAIK The Chronicle's editorial board and ACES have never backed any efforts to address this pressing issue - the most serious threat facing humankind after that of nuclear war. Big Oil and Big Coal have enormous political clout and do not want measures like cap and trade implemented to address this increasingly dire problem. When will The Chronicle editorial board and editorial staff begin backing strong measures to mitigate the consequences of man-made global climate change? This is a global concern that even the U.S. military takes very seriously in its strategic planning and its use of fossil fuels.

Al Gore is not a scientist.

Al Gore is not a scientist. Something like 99% of the worlds scientists have evidence that world is warming. Some republican skeptic think tanks have put millions of dollars (Money from Koch brothers) into funds trying to disprove the science. In the end, they finally came around saying the evidence is correct and that world is warming up. There are a lot of peer reviewed papers out there, do not be dismiss the science.

Saying the world is warming

Saying the world is warming is different than saying man is causing it. Mars is warming up, too. Who's causing that? Martians?

I bet our new state climatogist (weatherman for those of you in Ludowici) won't be spouting off any of the global warming is caused by man stuff. He saw what happened to the last one who tried that. Heh, heh, heh.

Riverman- That's not true

Riverman-

That's not true about Mars. Mars has no oceans and only a very thin atmosphere, which means there is very little thermal inertia – the climate is much more susceptible to change caused by external influences, but it's not warming up like our planet is. And there are serious consequences as our planets warms, whereas the temperature on Mars has no affect on us.

And scientists, people who have a lot of education and are checked by their peers all the time for accuracy say that carbon dioxide is a reason why our planet is warming up.

These are just facts. No political agenda or anything, just simple facts.

TParty said "And scientists, people who have a lot of education and are checked by their peers all the time for accuracy say that carbon dioxide is a reason why our planet is warming up."

Some do, some don't. Some that do don't know whether it's a significant factor, or not. Everybody knows carbon dioxide is created by people and animals breathing and that as the population increases, so does the production of carbon dioxide.

There is no scientific proof that mankind HAS made any difference in the earth's climate. None.

There is no scientific proof that mankind COULD make any difference in the earth's climate.

There is ample evidence that the scientific community has destroyed its credibility through dishonest attempts to prove man made global warming through the manipulation of sensors, data, and climate modeling.

These are just facts. No political agenda or anything, just simple facts.

TeaParty, from the National

TeaParty, from the National Geographic News: "In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row. "

I hope Deal slaps down hard anyone on the state payroll who espouses shutting down industry and jobs because of "manmade global warming." Any reporter who wants to write about it should go to work for Mother Earth News and have to donate his/her entire salary to OWSers.

How old is the planet?

If the planet is 100 years old, then maybe 30 years of date actually means something.

Until someone shows me hundreds of thousands of years of temperature data for the entire globe, I will be celebrating Earth Day by burning leaves, eating out of plastic containers and tossing my recycle-ables into the trash.

Can someone tell me what the average global temperate was 1,000 years ago? How about 10,000 or 100,000 years ago? Maybe 1 million?

Nope?

Didn't think so.

Some 2,500 scientists in more

Some 2,500 scientists in more than 130 countries, concluded that humans have caused all or most of the current planetary warming. Human-caused global warming is often called anthropogenic climate change.

Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.

I can continue posting fun facts, but it won't do any good to people who have their minds made up. When staunch skeptics of global warmer come around to the facts, and others don't -- not sure what to make of it. So it goes.

TP. the Hockey Stick graph

TP. the Hockey Stick graph was mathematically wrong as even proponets now admit. Explain the current warming of Mars and our own Medieval Warm Period. There was a scandal of falsified temperature recordings by proponents of the theory.

There was a time when scientists universally believed the world was flat.

There was a time when scientists swore up and down that the sun revolved around the earth.

Now scientists (some of them) claim global warming....climate change....seasons...or something like that. Hmmm...

I wonder if people who believe the global warming myth also believe the creation story.

Both require you to believe the earth is only a few thousand years old.

I don't need an expert. I walk outside and it's either hot, cold or ok. It was hot this summer and is usually hot in summer. It's hot and cold this month as usual. It will be hot and cold next month as usual.

Wow... where to begin.

Wow... where to begin. Provide data to the claims of falsified data, or only some scientists claim global warming to be true.

The Earth was formed about 4,500,000,000 years ago.

I'm also aware that in the beginning, the Earth's atmosphere contained very little oxygen (less than 1% oxygen pressure).

We also know that the last Ice Age began to recede about 20,000 years ago.

We know the concentration of carbon dioxide in the atmosphere, which was at 290 ppm in the year 1900, rose to 316 ppm in 1959, or at an average 0.44 ppm per year. Measurements of the concentration of carbon dioxide since 1959 (316 ppm) have revealed an increase to 392 ppm in 2011, or at an average 1.46 ppm per year.

I could go on, but what's the point?

Also, Mars is not Earth. Look at Venus if you want a better comparison, but still remember that our planet is different than others.

Are you also aware that in the beginning, the earth's atmosphere contained much more carbon dioxide than is in the atmosphere today? Even as recently as the carbonaceous period carbon dioxide levels were much higher than today.
