Situation Today……… FIG. 2.1. Yearly worldwide surface temperature takeoffs from the 1961 to 1990 normal. [Sources: NOAA/NCDC; CRU/UKMO (HadCRUT3); and NASA GISS.]

Slide 3

Situation Today

Slide 4

Climate What is it? Atmosphere? What is it? Climate  the normal condition of the air. Incorporates state variables and illustrative material, for example, overcast spread and precipitation, and so on. We can get this material immediately

Slide 5

Climate: What is it? Atmosphere  Is the long haul or time mean condition of the earth-environment framework and the state variables alongside higher request measurements. Additionally, we must depict extremes and repeat frequencies. In ‘English’: A long haul outline of what has happened.

Slide 6

Climate and Climatology Climate can, in this manner, be distinct and let us know something about, ‘what is possible’ in a given district.

Slide 7

Climate Question When we examine atmosphere, what do we mean by “long-term”? What\'s more, why did we pick such a period?

Slide 8

The Answer! The World Meteorological Organization standard Climate averaging period is 30 years. Two reasons: A) This is sufficiently long to dispense with “year to year” varieties in atmosphere, and B) it’s not very long in respect to human life compasses!

Slide 9

Climate: What is it? Climatology is the investigation of atmosphere in a for the most part spellbinding and a measurable sense. Climatologists contemplate these issues, and in addition changes in atmosphere. Climatology is, obviously, a mainstream subject today as a result of the worry over environmental change.

Slide 10

The Climate System/What is it? The Earth-Atmosphere framework is a coordinated arrangement of which the environment is one and only part!

Slide 11

The Climate System alternate parts of the atmosphere framework are: The Cryosphere (Glaciers, Antarctica) The Oceans (and freshwater as well) The Lithosphere (soil, landmasses) The Biosphere (life  Plants and Animals)

Slide 12

The Climate System The earth-air framework, obligingness of Dr. Richard Rood. (http://aoss.engin.umich.edu/class/aoss605/addresses/)

Slide 13

The Climate System Each piece of the atmosphere framework interfaces with the other. Every part by and large advances or changes all the more gradually, the environment is a “quick response” framework.

Slide 14

The Climate System We make two presumptions about the atmosphere framework: That the vitality that comes into the framework measures up to the vitality going out, and That the mass inside of the framework is preserved.

Slide 15

Global Warming: Attribution How would we distinguish humanity’s commitment to atmosphere? To start with, we know there is an in number connection between\'s worldwide temperature and CO 2 focus, ……

Slide 16

Global Warming: Attribution ……but on a VERY long time-scale (a huge number of years) Graphic like this in “An Inconvenient Truth”

Slide 17

Global Warming: Attribution obviously we all have seen this chart:

Slide 18

Global Warming: Attribution The rate of CO 2 increment has been unfaltering up to the mid 2000’s, in spite of the fact that there is some proof it is dropping. “CO 2 – rising”

Slide 19

Global Warming: Attribution We can “fingerprint” CO 2 focuses by it’s mass (proportion of different isotopes) and there is doubtlessly an expand\'s percentage in CO 2 is produced by people (industry)

Slide 20

Global Warming: Atmospheric Models Also, we can utilize barometrical models: (General Circulation models) and analyze the effect of changing the CO 2 sum (Climate cynics)

Slide 21

Model projections

Slide 22

Model Projections Climate models extend an increment in worldwide temperature of 1.5 o – 12 o F by the year 2100. This has realized stresses: Increased warmth waves Droughts Floods Hurricanes Storminess Habitat misfortune Etc…….

Slide 23

Global Warming: The body of evidence against? How do cynics counter? They can demonstrate that temperature on different scales corresponds to characteristic wonder. We can look at:

Slide 24

Global Warming: The cast against? ….US temperatures to temperatures in the Pacific area

Slide 25

Global Warming: The argument against? More proof? (Corresponds to the Pacfic Decadal Oscillation) (Jones et al. furthermore, NASA – GISS lab)

Slide 26

Global Warming: The body of evidence against? On hundreds of years! (Associates toward the North Atlantic Oscillation) (Robinson et al. 2006, Weather)

Slide 27

Natural atmosphere variability: (Dr. Roy Spencer, NASA) ~100 Year Periods of Warming and Cooling have been Common Over the Last 2,000 Years. On the off chance that late warming is brought about by CO2, then what created the various periods Medieval Warm Period of warming and cooling?

Slide 28

Climate change: The body of evidence against? What\'s more, millenia……..

Slide 29

Global Warming: The argument against? Sun based compelling on ice age scales (Climate Skeptics):

Slide 30

Global Warming: The body of evidence against? Sun powered movement (Sunspots) (R.D. Tkachuck –Geophysics Research Institute):

Slide 31

Global Warming: The argument against? Volcanism – researchers have demonstrated that Volcanic constraining tends to cool atmosphere, and the most recent 150 years have been moderately tranquil! Cynics counter the model results with a flood of issues. IPCC has the capacity measure these climatic impacts and appraisal their blunder.

Slide 32

Global Warming: The Case Against? Models are essentially a theory on how we think the environment functions. Three primary blemishes: Incomplete/missing material science (at limits/mists) Numerics are lacking Observational lapse/insufficient information!

Slide 33

Climate Change: The body of evidence against? “Planet Climate model!”

Slide 34

What has been watched? In Missouri……. (Missouri Climate Center)

Slide 35

What has been watched? Acquired from the Missouri Tree-Ring Laboratory Stambaugh, M.C. what\'s more, R.P. Guyette. (in prep). 1000 years of tree-ring reproduced dry season in the Central United States.

Slide 36

What has been watched? Around the world…….. (from Bulletin of the AMS)

Slide 37

Climate, Climate Change & Hurricanes Is a worldwide temperature alteration expanding the tropical storm numbers?

Slide 38

Climate Change: Global warming Recently, people have been thought to add to atmosphere change…. (Mann et al. 1998)

Slide 39

Global Warming Global warming as we utilize it here, means the commitment of mankind to the increment in carbon dioxide. Now and again called the “greenhouse effect”, however there is a characteristic “greenhouse effect” so we’ll spare this term of “nature’s contribution”.

Slide 40

Global Warming Can people affect the atmosphere?

Slide 41

Global Warming The answer, I accept, is yes we can, however our commitment is little. Worldwide temperatures since 1860 have risen 0.6 – 1.2 degrees Fahrenheit. The safety buffer is 0 – 0.5 degrees. Possibly the temperatures have not risen? (Just a little few uncertainty this)

Slide 42

Global Warming What keeps the planet warm? Nursery gasses, for example, water vapor and Carbon Dioxide trap heat in our climate. Without these, earth’s atmosphere would be darn cool!

Slide 43

Global Warming We comprehend the water cycle http://www.kidzone.ws/water/.

Slide 44

Global Warming Water vapor is the most powerful nursery gas, ordinarily more strong than Carbon dioxide Water vapor is the main problem, however we don’t comprehend what the future holds…..

Slide 45

Global Warming We don’t comprehend future water vapor focuses or the future dispersion of shadiness.   Nor do we see totally the Carbon Cycle! (In any case, enhancements are being made)

Slide 46

Slide 47

What would we be able to do about environmental change? A flippant solution……. (turned into a privateer!)

Slide 48

What would we be able to do about environmental change? On the off chance that you trust in a noteworthy anthropogenic component…….. We can do bounty! (protection, and Policy-wise)

Slide 49

What would we be able to do about environmental change? On the off chance that you trust that nature is driving environmental change in extensive measure…….. We can do nothing! On the other hand, I trust we should be great stewards

Slide 50

Let’s wrap it up Global warming -Yes, atmosphere is warming -perhaps people are contributing, yet to what degree? - there are numerous things about the atmosphere still not caught on. - what would it be advisable for us to do about it?
