Global warming and it's natural and adverse affects on our environments and subsequent economy is a subject I'm interested in.

When I look to the media for news and information I see clear data supporting facts that human beings are assisting in the evolution of our climate system by the release of green house gasses (carbon dioxide) into our atmosphere.

Almost nonstop there are massive disasters occurring more rapidly and abundantly somewhere around the world that takes human lives and can cost millions/billions in damages.

I personally believe that some of these disasters are rooted in and resulting from man-made climate change. Therefore, I'm creating this thread for all those who believe and agree that climate change is adversely affecting our earth overall so we can post our views in support of this topic.

I totally agree. It's getting hotter each year. Humidity in my country reached record high of 39�,hottest ever recorded here, though only in separate provinces. Approaching midyear means rainy season, and that means rainy months, floods, landslides and typhoons. Experts says we should be prepared for much stronger and devastating typhoons like that of Haiyan.

Lines of Evidence: Greenhouse Gases

How do we know that greenhouse gasses lead to warming?

As early as the 1820's, scientists began to appreciate the importance of certain gases in regulating the temperature of earth.

Green house gases which include water vapor, carbon dioxide, methane, and nitrous oxide act like a blanket covering the earth, trapping heat in the lower atmosphere, known as the troposphere.

Green house gasses are critical for keeping the planet warm enough to support life as we know it.

Here's how the greenhouse effect works:

As the sun's energy hits earth, some of it is reflected back to space, but most of it is absorbed by land and oceans.

This absorbed energy is then radiated upward from the surface of the earth in the form of heat.

In the absence of greenhouse gasses this heat would simply escape to space, and the planet's average surface temperature would be well below freezing.

But greenhouse gases absorb and redirect some of this energy downward, keeping heat near the surface of earth.

As concentrations of heat trapping greenhouse gasses increase in the atmosphere, earth's natural greenhouse effect is amplified like having a thicker blanket, and surface temperatures slowly rise.

Reducing the levels of greenhouse gasses in the atmosphere would cause a decrease in surface temperature.

How do we know that earth has warmed?

Scientists have been taking widespread global measurements of earth's surface temperature for centuries.

By the 1880's, there was enough data to produce reliable estimates of global average temperature.

These data have steadily improved. And today, temperatures are recorded by thermometers at many thousands of locations. Both on land and over the oceans.

Different research groups, including NASA"S Goddard Institute for Space Studies, Great Britain's Hadley Center, and the Japanese Meteorological Agency have used these raw measurements to produce records of long term surface temperature change.

Research groups work carefully to make sure the data aren't skewed by such things as changes in the instruments taking the measurements. Or by other factors that affect local temperature. Such as additional heat that has come from the gradual growth of cities.

These analyses all show that earth's average surface temperature has increased by more than 1.4 degrees Fahrenheit over the past 100 years.

With much of this increase taking place over the past 35 years.

A temperature change of 1.4 degrees Fahrenheit may not seem like much if you're thinking about a daily or seasonal fluctuation.

However, it is a significant change when you think about a permanent increase averaged across the entire planet.

For example, 1.4 degrees is more than the average annual temperature difference between Washington D.C and Charleston, South Carolina which is more than 450 miles south of Washington.

Think about this...

On any given day a difference of 9 degrees Fahrenheit might be the difference between wearing a sweater or not.

But a change of 9 degrees in the global average temperature is the estimated difference between the climate of today and an ice age.

In addition to surface temperature other parts of the climate system are also being monitored carefully.

For example...

A variety of instruments are used to measure temperature, salinity, and currents beneath the oceans surface.

Weather balloons are used to probe the temperature, humidity, and winds in the atmosphere.

A key breakthrough in the ability to track global and environmental changes began in the 1970's with the dawn of the era of satellite remote sensing.

Many different types of sensors carried on many dozens of satellites have allowed us to build a truly global picture of changes in the temperature of the atmosphere, and of the ocean and land surfaces.

Satellite data are also used to study shifts in precipitation and changes in land cover.

Even though satellites do not measure temperature in the same way as instruments on the surface of earth, and any errors would be of a completely different nature, the two records agree.

A number of other indicators of global warming have also been observed.

For example...

Heat waves are becoming more frequent.

Cold snaps are now shorter and milder.

Snow and ice cover are decreasing in the northern hemisphere.

Glaciers and ice caps around the world are melting.

And many plant and animal species are moving to different latitudes, or higher altitudes, due to changes in temperature.

The picture that emerges from all of these data sets is clear and consistent.

Earth is warming.

it is freezing cold here today.....may 16th!!

You are right

1.4 degrees in 100 years... haha..

In 1815 Mount Tambora erupted in what is considered the largest in modern history at VEI 7... The average temperature of the earth dropped 5 degrees.. 1816 was called the year without a summer in the US.. man vs nature... I know who wins..

funny,everyone howling about CO2,yet no one even goes near Watervapor,which is much more plentiful in the Atmosphere,and outstrips CO2 and Methane by far!
Problem is,that it is natural,and thus a very Inconvenient Truth for OwlGore!

Wow, just keep beating a dead horse. And with the same old tired crap, the UN and IPCC, those same idiots that are promoting Agenda 21.

Imagine, NASA scientist mad at NASA for belittling their reputations.

Sure it's so hot...

Freezing cold March sets records across Europe

And for the absolute capper, a report from one of the triage of global warming:

NOAA: Winter 2013-2014 Among Coldest on Record in Midwest; Driest, Warmest in Southwest

OMG, has Al Gore lost one of his lair organizations?

Another lame a$$ source, all the way from Woodrow Wilson.



So I guess they forgot about those 31,000 scientist that signed that climate change was a hoax, so does that mean that consensuses has a new definition?

But then just who are these idiots? Organization and Members: By National Research Council (U.S.)

Established in 1916 by congressional charter of the National Academy of Sciences. And before the war it was funded by government but now it is supported solely by private sources. They can be called upon any Department of Government to help. And by Executive Order on May 18, 1918, the National Research Council was added as a measure of national preparedness, because it wasn't authorized by congress. Sounds like an Odumbocare training document. And from that loving President that gave us the IRS and Federal Reserve.

And for real excitement, scan down the book and look at some of the original members.

This is just more of the same BS from the proceeding by President Wilson's National Research Council, you know those guys that came into existence by Executive Order because congress forgot in the original act.

Get warm clothes, 20 to 30 more years before the next warming cycle and even that wont be that warm for an estimated 400 to 500 years.

I wonder what Chicago-area residents thought of the snow that fell on their homes this week?

That they forgot to pay their carbon tax bill and where penalized?

Global Warming - A video by NASA

It seems to me if people didn't really believe we have any man-made hand in climate change, NASA wouldn't have spent so much money on satellites and manpower to watch the earth and study its changes, then try and help earth's residents to see whats happening overall by creating videos and such so we can make informed decisions about our part in the evolution.

Climate Change Will Hurt Nations' Credit Ratings, S&P Warns

Well, this is one side of climate change I hadn't thought about yet. But it makes perfect sense.

If the weather prevents us from being able to make a living and paying our bills on time quite naturally our credit ratings will be an added crippling factor to our lives spinning out of control.

OUCH! There's just no end to the damage that the unusual change in weather patterns can create.

Countdown to oblivion: The real reason we can’t stop global warming

www.salon.com/2014/05/18/countdown_to_oblivion_the_real_reason_we_cant_stop_global_warming/

There was a time when the environmental damage we produced remained somewhat localized, confined to specific places. That time is gone.

Today, nonindustrial areas, such as Greenland and the Antarctic, experience the industrial pollution generated in the United States and in Russia, to mention just two countries.

Damage produced in particular sites now scales up, driven by the vastness of destruction, and becomes a planetary problem that drifts back down to hit even those places that did not contribute to the damage.

Greenhouse gases (including carbon dioxide, methane, nitrous oxide, and particulate matter such as black carbon) are key causes of climate change.

Diverse measures arrive at an estimate that human activity has generated 350 billion tonnes of carbon since 1959; 55 percent of this has been taken up by the oceans and land, and the rest has been left in the atmosphere.

In 2009 alone, global carbon dioxide emissions totaled 30 billion tonnes.

By 2011, annual emissions had increased by 5.3 percent to 31.6 billion tonnes.

And by early 2013, the level of carbon dioxide in the atmosphere surpassed the critical level of 400 parts per million. This is a level not seen on earth since the Pliocene era 3 million years ago.

Under current conditions, global CO2 emissions (including emissions related to deforestation) will reach 41 billion tonnes per year in 2020.

The EPA estimates that industrial emissions account for 50 percent of greenhouse gases emitted in the United States, and industry is almost certainly responsible for an even higher proportion of China'��s huge and growing emissions.

At this scale, and with the relationship of carbon dioxide to climate change, industrial pollution is a driver of massive global problems.

One major effect is rising land temperature.

The numbers for the current warming phase are extreme compared to the available historical records.

May 2012 was ��the 327th consecutive month in which the temperature of the entire globe exceeded the 20th-century average,�� writes Bill McKibben.

The spring of 2012 was the hottest ever, and marked the biggest difference with the average seasonal temperature recorded for any season.

In the United States, the month of June 2012 broke 3,215 heat records across the country, and May 2012 was the warmest May in the country'��s recorded history.

There are debates and disagreements about the precise rate, timing, and level of increase. But very diverse types of studies all document this upward trend.

in 22 years something is going on. we have found cities all around the oceans coasts where civilizations once were. seems as if the oceans rose. whatever u want to say is going on we have defiant data that the polar caps are melting. and very fast. this video show just since 1980. and we know every year they are melting more. do you not believe the oceans could rise and displace millions and millions of people? ice does not melt from cold weather.

Pure BS, NASA is part of Washington and that is controlled by Odumbo the same as Agenda 21 of which carbon tax plays a big part. You know those people that make up IPPC, the reports that NASA keeps referring to. Same as that wonderful National Research Council, funded by government originally, now private funded, wait for it, wait for it, corporations and those government owning foundations, Ford, Carnegie, Rockefeller, Morgan. You know the ones that established the Federal Reserve and IRS and that own this nation.

So go ahead and keep drinking the kool-aid while all the alphabet soup people keep buying off everything they touch to maintain the masses as slaves.
