Topic: CLIMATE CHANGE IS REAL

Climate change can also be caused by human activities, such as the burning of fossil fuels and the conversion of
land for forestry and agriculture. Since the beginning of the Industrial Revolution, these human influences on the
climate system have increased substantially. Mar 28, 2019

Climate Change
Climate change is changing the way we interact with our environments. With a changing climate come potential
consequences for life on Earth.

Climate change is currently occurring throughout the world as a result of global warming. Global warming is an
increase in the planet’s overall temperature due to the burning of fossil fuels, such as natural gas, oil, and coal.
Burning these materials releases certain gases into Earth’s atmosphere. These gases trap the heat from the Sun’s
rays inside the atmosphere, causing Earth’s average temperature to rise.

The warming of the planet impacts local and regional climates. Climate is different from weather because it is
measured over a long period of time whereas weather can vary daily, or from year to year. The climate of an area
includes averages of seasonal temperatures, rainfall, snowfall, and wind patterns. Different places have different
climates. A desert, for example, is referred to as an arid climate because it is dry year round. Other types of climate
include tropical, which is hot and humid, and temperate, which has warm summers and cooler winters.

The effects of climate change make average temperatures and weather patterns more unpredictable. In an arid
region, for example, this may mean higher than average temperatures and more severe or prolonged droughts. In a
temperate region, it may mean that there is a lot of rain one year, and then very little rain the next year. These
unpredictable weather patterns can therefore make it difficult to grow crops and maintain farmland in temperate
zones because the temperatures and rainfall that farmers had come to expect can no longer be relied upon. Climate
change has also been connected with other damaging weather events such as more frequent and more intense
hurricanes, floods, downpours, and winter storms.

What Is Climate Change?

Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place
usually gets in a year. Or it could be a change in a place's usual temperature for a month or season.

Climate change is also a change in Earth's climate. This could be a change in Earth's usual temperature. Or it could
be a change in where rain and snow usually fall on Earth.

Weather can change in just a few hours. Climate takes hundreds or even millions of years to change.

How Does NASA Study Climate Change?

Some NASA satellites look at Earth's land, air, water and ice. Other tools look at the sun and the energy it sends out.
Together, these are important for learning about Earth's climate. Using all these tools can help scientists learn how
climate might change.

What Can You Do to Help?

Scientists think we can do things to stop the climate from changing as much. You can help by using less energy and
water. Turn off lights and TVs when you leave a room. Turn off the water when brushing your teeth. You also can
help by planting trees.

Another way to help is by learning about Earth. The more you know about Earth, the more you can help solve
climate problems.
 Ano ang sanhi at dahilan ng climate change o pagbabago ng klima?
Maraming mga bagay ang maaring maging dahilan at sanhi ng climate change.
Likas na mga sanhi – Ang distansya ng araw sa Earth ay maaring maging sanhi ng climate change, kapag ito ay
malapit ay mas mainit, at pag malayo naman ay malamig. Maari ding maging dahilan ng climate change ang
pagputok ng mga bulkan sa ilalim ng karagatan.
Kagagawan ng Tao – Ang climate change ay maaari ding maging sanhi ng mga gawain ng tao, tulad ng mga
pagsusunog ng Fossil fuels at ang conversion ng lupa para sa agrikultura at pagpapatayo ng mga gusali. Mga buga
ng mga sasakyan na carbon dioxide at pagsunog ng mga plastic ay isa rin sa rason. Simula ng tayo ay dumating sa
Industrial Age, ang impluwensya ng tao sa pagbabago ng klima ay mas lalong nadagdagan.

Ano ang epekto ng climate change o pagbabago ng klima?

Ang mga sumusunod ay ang pwedeng maging epekto ng climate change:

 Patuloy na pagtaas ng temperatura – Mas lalong iinit ang mundo

 Paghaba ng panahon ng tag-init – Hahaba ang season ng tag-init at El Niñ o
 Pagdagsa ng maraming bagyo – Dahil sa sobrang init nagbabago ang precipitation, may mga lugar na
hihina ang dagsa ng ulan at meron din lugar na dadagsain ng bagyo.
 Pagtaas sa antas ng tubig dagat – Ang mga nyibe at yelo sa north at south pole ay matutunaw  at
magiging dahilan ng pagtaas ng tubig dagat.

Solusyon sa climate change?

Paano maiiwasan ang climate change? Ang climate change ay hindi natin mapipigilan, ngunit mayroong mga paraan
upang ang pagbabago ng klima at pagtaas ng temperatura ay madahandahan.

 Sumuporta at sumali sa mga usapin ukol sa kung ano ang climate change.
 Maging resposabling mamamayan at wag magsunog ng mga plastik.
 Maging matipid sa enerhiya.
 Tigilan ang pag putol ng mga punong kahoy bagkos magtanim nito.
 Gumamit ng Biofuels.

Ano ang CLIMATE CHANGE?

Ang climate change ay ang pagbabago ng klima o panahon dahil sa pagtaas ng mg greenhouse gases na nagpapainit sa
mundo.  Nagdudulot ito ng mga sakuna kagaya ng heatwave, baha at tagtuyot na maaaring magdulot ng pagkakasakit o
pagkamatay.  Kapag tumaas ang temperatura ng mundo, dadami ang mga sakit kagaya ng dengue, diarrhea,
malnutrisyon at iba pa.

Sanhi ng CLIMATE CHANGE

Ayon sa pag-aaral, ang dalawang sanhi ng climate change ay ang:
1.  Natural na pagbabago ng klima ng buong mundo nitong mga nagdaang matagal na panahon.  Ito ay sama-samang
epekto ng enerhiya mula sa araw, sa pag-ikot ng mundo, at sa init na nagmumula sa ilalim ng lupa na nagpapataas ng
temperatura o init sa hangin na bumabalot sa mundo.
2. Mga gawain ng tao na nagbubunga ng pagdami o pagtaas ng carbon dioxide at iba pang greenhouse gases )GHGs).
ANg GHGs ang nagkukulong ng init sa mundo.  Ang pagbuga ng carbon dioxide ng mga sasakyang gumagamit ng
gasolina, ang pagputol ng mga puno na siya sanang mag-aalis ng carbon dioxide sa hangin, at pagkabulok ng mga bagay
na organic na nagbubunga ng methane (isa pang uri ng GHGs) ay ilan sa mga dahilan ng climate change.

The evidence for rapid climate change is compelling:

Global Temperature Rise


The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the
late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the
atmosphere.4 Most of the warming occurred in the past 35 years, with the five warmest years on record taking
place since 2010. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year
— from January through September, with the exception of June — were the warmest on record for those
respective months.

Warming Oceans

 The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean
showing warming of more than 0.4 degrees Fahrenheit since 1969. 6

Shrinking Ice Sheets


The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate
Experiment show Greenland lost an average of 286 billion tons of ice per year between 1993 and 2016, while
Antarctica lost about 127 billion tons of ice per year during the same time period. The rate of Antarctica ice mass
loss has tripled in the last decade.7

Glacial Retreat

Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies,
Alaska and Africa.8

Decreased Snow Cover


Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over
the past five decades and that the snow is melting earlier. 9

Sea Level Rise


Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double
that of the last century and is accelerating slightly every year. 10

Extreme Events

The number of record high temperature events in the United States has been increasing, while the number of
record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of
intense rainfall events.12

Ocean Acidification

Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30
percent.13,14 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence
more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is
increasing by about 2 billion tons per year. 15

Climate change is real and man-made, and there is overwhelming scientific consensus that this is true
Human-produced pollution is causing climate change that is dangerous now and will become much more dangerous in
the future if we do not act.

NASA, the National Academy of Sciences and every major scientific organization recognizes this. Indeed, 97 percent of
climate scientists worldwide agree that climate change is real and driven by human activity. In the scientific world, that
is consensus.
Climate change reports consider a wide range of possible future scenarios

Major climate change assessments from reputable scientific institutions — such as the U.S. government’s National
Climate Assessment and the United Nations Intergovernmental Panel on Climate Change’s special report on
different levels of warming — consider a wide range of future conditions, from the use of advanced technologies
that remove carbon dioxide from the atmosphere, to escalating emissions from the absence of climate action.

Our changing climate

Scientific evidence is clear that our climate is changing.

We know this from:

 direct surface temperature measurements

 changes in rainfall and weather patterns
 an increase in the frequency of extreme weather events
 loss of Arctic sea ice
 sea level rise
 melting of the Antarctic and Greenland ice sheets, and from the NZ Southern Alps - watch this
video: Glaciers don’t lie on the retreat of New Zealand glaciers [NIWA Taihoro Nukurangi website]
 shifts in the geographic ranges distribution of some plant and animal species
 earlier unfolding of new leaves in spring 
 changes in bird migration patterns.

Many of these changes pose serious risks to human life and property. Exposure to extreme drought, heat, rainfall,
and coastal inundation are projected to worsen in many parts of New Zealand and around the world.
