Biology II

Global Warming Lecture at Botanical Garden

Dr. Steven Jacksons resentation dislayed that !arth is al"ays changing

and that the e#ects o$ global "arming should be looked at. %here "as a steady

increase o$ carbon dio&ide levels since the '()*s and the trend seems to be linear

and about to turn e&onential. +e addressed that !arths climate and temeratures

change "hich can also change the environment. !arth is also a lanet o$ ,doom- as

natural bottlenecks occur and huge losses o$ communities come natural. limate

change is eisodic and rarely smooth. !arth undergoes eriodic temerature shi$ts

and he believes "e are in the middle o$ one right no". !stablished oulations "ill

continue to ersist in adverse climate changes. /dation "ill occur and secie

interactions "ill lay a ma0or role in the dynamics o$ the changing "orld. !arth is a

lanet o$ survivors "here secie range greatly outnumbers e&tirations. Biodiversity

loss is more like cause by destruction and trans$ormation by humans than by

natural climate changes.

Dr. 1atty 1arkers resentation "as about the e#ects o$ health and human

oulation $rom the climate changes. She e&lained the ossibility o$ malaria

becoming a ma0or issue in regions "here it "as not an issue be$ore. 1eole in richer

arts o$ the "orld "ill have a bit o$ a anic "hen it hits then as they "ould not kno"

ho" to deal "ith it. She believes that these eole "ill in the end have a better

chance at 2ghting the disease because o$ their 2nancial and economic situations.

3egions that are o$ten a#ected by malaria are usually the southern hemishere and

those regions are the ones that are considered oorer. %he oorer nations "ill have

to deal "ith more health roblems as the situation "orsens. %hey "ill not have the

means to combat these issues. /$rica4 India and South !ast /sia "ill be the hardest

hit regions. %he 5orthenr +emishere is actually mostly resonsible $or these

climate changes and she urges that they take resonsibility $or it. !ven though

there "ill not be a signi2cant change in the northern hemishere it "ill hit everyone

else very hard. Since "e have the technology and the climate advantage "e should

begin to take care o$ others.

Dr. Lea63achel 7osniks resentation "as ho" the economic situation cannot

be redicted as o$ no". Some economists argue that climate change is occurring

no" "hile and action must be taken "hile others say that climate change is

occurring but at a rather slo" and unremarkable rate. 8ne side says that lans

should be resented and carried out in order to sto the markets $rom crashing. %he

other side dismisses that idea and rooses that markets should not "orry and

continue to roduce as normal. %here are t"o economic imlications. !conomic

imlication number one states that i$ climate changes $ast4 the markets "ill not

have enough time to adat and a crash "ill occur. I$ climate change is gradual4 the

ad0usted costs "ill rise4 but "ill be lo"er than i$ the oosite had haened.

!conomic imlication number t"o is that the rich "ill ultimately do better than the

oor. %he 5orthern hemishere countries "ill be able to coe "ith the ne" changes.

%he changes may a#ect the living conditions a bit but overall4 everything "ill stay

the same as it had be$ore. 1oor countries may "ant to become rich by using "hat

they can and ollute to become industriali9ed. What usually haens is that once a

oor country becomes rich they "ill soon become environmentally $riendly. %hat is

"hat haened in the :nited States and !uroe. hina is no" on the rise.

Dr. David 3obertsons resentation "as about olitics and climate change.

Many eole "ill "ant to make legislations and 2ght $or o;ce o"ers. /lso he

resented the di#erent vie"s o$ global "arming $rom around the "orld. %he :nited

States seems to be the least "orried o$ nations that are concerned about the

environment. :S reublicans also vie" that climate change and global "arming are

not as imortant as the democrats. /lso eole "ith religious vie"s are less likely to

vie" climate change as an imortant $actor.
