(Less than) half the truth from NZ's Ministry of the Environment

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.

Flooding in Canterbury this year. Such events are likely to become more 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.

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."
