A
bit of fascinating news to the lamenews (MSM)- it’s not as if we’ve
got an emergency is it? Lol
Go
back to sleep, hobbits.
Revealed: NZ's emissions fifth highest in OECD
New
Zealand has the fifth-highest-level of emissions per person in the
OECD, a new government report has revealed.

New
Zealand's greenhouse gas emissions have risen by almost a quarter in
the last 25 years, a report
from the Ministry for the Environment
Last
year the amount of carbon dioxide in the Earth's atmosphere reached
the highest level in 800,000 years. And 2016 was the warmest year
since 1909; the five warmest years on record have been in the last 20
years.
That
warming had led to dryer soils in a fifth of sites tested throughout
New Zealand, the report said. It also said the frequency and
intensity of drought in drought-prone regions was expected to worsen.
"The
number of frost days (below 0 degrees Celsius) decreased and the
number of warm days (over 25 degrees Celsius) increased at around
one‐third of measured sites over the period 1972-2016," the
report said.
Sea
temperatures have increased 0.7 percent in the last century and
coastal sea levels had increased 22 cms in places.
"Climate‐related
changes to our oceans will continue for centuries and are threats to
marine life, commercial and recreational fishing, Māori customary
practices, and other cultural and recreational practices. Rising sea
levels are threatening public and private coastal communities,
infrastructure, cultural sites, and marine habitats," the report
said.
Secretary
for the Environment Vicky Robertson said while New Zealand isn't a
large contributor of emissions globally (making up just 0.17 of
global emission) it is certainly affected locally so needs to act.
"The
future impacts of climate change on our lives all depend on how fast
global emissions are reduced and the extent to which our communities
can adapt to change.
Some
New Zealand climate change impacts may already be irreversible,
Government report says

Climate
change may have already had an irreversible impact on New Zealand's
natural systems and the effects are likely to worsen, a
new Government report says.
Data
showed conclusively that temperatures had already risen by one
degree in New Zealand, which would have an impact on the economy,
extreme weather events, biodiversity and health.
The Our
Climate and Atmosphere report, released by the Ministry for the
Environment (MfE) and Statistics New Zealand on Thursday, revealed
the country's glaciers had lost nearly a quarter of their
ice since 1977, and sea levels had risen between
14 centimetres and 22cm at four main ports since 1916.

frequent due to climate change.
Meanwhile,
our contribution to global greenhouse emissions had
increased and sea level and temperature rises were forecast to
gain momentum.
Soils
in some areas had become drier and both the acidity
and the temperature of the ocean had risen.

Glacier in 2014. Our shrinking glaciers are a sign of a warming
climate.
Last
year was the country's warmest year since records
began and the five warmest years on record had occurred in the
last 20 years.
The
number of extreme weather events had increased, as had the
insurance cost of those events, Insurance Council of New Zealand data
showed.
New
Zealand had the fifth-highest emission levels per person in
the OECD, the report said.
Since
1990, gross emissions increased 24 per cent, while net emissions
increased 64 per cent. Net emissions accounted for carbon
stored in forests, which was released when they were cut
down.
Our
high rate of emissions was attributed to an unusually large share of
agriculture emissions and high car-ownership rates.
"While
New Zealand is not a large contributor of emissions globally, we
are certainly affected locally and we need to act on what that
means for us," secretary for the
environment Vicky Robertson said.
The
scope of the report did not include recommendations for tackling
emissions and Robertson said the purpose was to
open the conversation.
"We
are working quite significantly to bring together all the
public services towards advising collectively and consistently
around what government could do to create a pathway to our 2030
targets."
Current
targets were to reduce greenhouse emissions to 30 per cent below
2005 levels by 2030.
The
document singles out transport as a key driver of increased
emissions, which had jumped 78 per cent since 1990 and now equated to
18 per cent overall.
However,
agriculture emissions sat far higher, constituting just under
half of overall emissions and had also climbed significantly in
the same period.
Robertson
said the report had not sought to downplay agriculture's
impact and she would not be shying away from it in
policy advice.
While
New Zealand's emissions had continued to climb, the United
Kingdom reduced its emissions by 26 per cent from 1990 to 2013,
Sweden by 25 per cent, and France by 11 per cent.
Robertson
refused to give New Zealand a scorecard on its performance
to-date, but said now was the time to make changes.
"The
future impacts of climate change on our lives all depend on how
fast global emissions are reduced and the extent to which
our communities can adapt to change."
University
of Otago environmental epidemiologist Simon Hales said the
main takeaway was that the country was not living up to its
international obligations on climate change.
"We
require a much better, more quantitative understanding of the likely
adverse impacts of climate change on human health than the brief,
vague statements in the MfE report."
Climate
change would likely have an impact on our already
struggling biodiversity.
Research
showed there was already a growing imbalance in the gender
split of tuatara.
Warmer
temperatures in tuatara nests were more likely to produce male
offspring; on North Brother Island in the Cook Strait, the ratio of
male to female tuatara had increased from 1:66 to 2:36 in recent
decades.
Warmer
temperatures also increased the wasp population in beech forests,
which resulted in less food for native species, and the frequency of
masts (tree seed dropping), creating food for rodents, which
attract predators.
"We
can expect to face possibly costly decisions around how we manage the
effects of a changing climate for our unique and celebrated
native biodiversity," the report said.
Climate
change would also affect the economy and our physical and mental
health, although the extent for both was not yet clear.
Rising sea
levels and increasing extreme weather events would affect
coastal communities, likely requiring some communities to move.
An
earlier risk census determined around $19
billion worth of buildings were at risk of rising sea levels.
Drier
conditions in some areas would have an impact on agriculture and
the rates of some diseases may increase, as well as exposure to heat
waves, flooding and fires.
The
report also determined the atmosphere's "ozone hole",
which was attributed to high levels of melanoma in
Australia and New Zealand, was shrinking.
It
had decreased 21 per cent from its largest size, which was
reached in 2006, and may no longer exist mid-way through the
century.
It
was largely due to a global effort to reduce the usage of ozone
depleting substances, such as those in refrigeration and air
conditioning equipment.
Niwa
atmospheric researcher Richard McKenzie said the report was
heartening, but the country still had to be vigilant.
"The
situation is delicate at present and we remain at risk from
possible effects from future volcanic eruptions."
