1. Latest NZ scientific climate change report today 29th March 2019.
   NZ P.M. Jacinda Ardern needs to read this NZ scientific report released today.

   Our NZ climate is now moving out of reach of changing it so this report from senior NZ scientists are warning the Labour coalition Government.

   Global State of the Climate 2018 – Expert Reaction

   Press Release: Science Media Centre
   The physical signs and socio-economic impacts of climate change are accelerating according to the World Meteorological Organization (WMO).
   In their 2018 State of the Global Climate report, they say 2018 saw record sea level rise and exceptionally high land and ocean temperatures over the past four years, continuing the warming trend observed over the past two decades.
   The statement also covers climate impacts on human populations over the past year, such as at climate hazards, displacements and food security.
   The SMC asked experts to comment, feel free to use these comments in your reporting.
   Professor James Renwick, climate scientist and Head of the VUW School of Geography, Environment and Earth Sciences, comments:
   “The 25th annual State of the Climate report from the WMO is an excellent and accessible summary, but it makes for sobering reading. Carbon dioxide concentrations are at record levels, ocean heat content and sea levels are both at record highs, sea ice extent is well below normal in both hemisphere, glaciers and ice sheets are melting. On and on in the now-familiar litany of all the ways the climate is warming and changing around us. Even more worrying is the range of associated extreme weather events and impacts on human populations. World hunger is on the rise and we are now talking of millions of people displaced as a result of weather and climate extremes.
   “Ecosystems are being affected worldwide, on land and in the oceans, where acidification is associated with rising temperatures and loss of dissolved oxygen. The record heat in New Zealand and the Tasman Sea during summer 2017/18 is an example of what we can expect much more of in future years. With no action on climate change, that record warm summer in New Zealand would be counted as a cold summer in another 50 years. The associated increases in climate and weather extremes would displace hundreds of millions and would threaten the fabric of societies everywhere.

   “The globe is currently running a temperature of about 1°C above pre-industrial levels. To rein in the warming at no more than 1.5°C above pre-industrial, global emissions need to halve by 2030, and go to zero by 2050. Yet, emissions increased to record levels in 2018! Policy-makers must really take on board that climate change is an existential threat to global society, to the global economy, and to all ecosystems on earth. I hope the planned United Nations Climate Action Summit later this year really galvanises action by governments around the world.”
   No conflict of interest.
   Gregor Macara, climate scientist, National Institute of Water & Atmospheric Research (NIWA), comments:
   “In a week that has seen the highest 48-hour rainfall total ever in New Zealand, it seems fitting that the World Meteorological Organization (WMO) is highlighting the increasing impacts of climate change around the world.
   “New Zealand is far from immune and has experienced many of the indicators the WMO has concluded are becoming more pronounced globally.
   “These include:
   • New Zealand’s hottest ever month in January 2018 when the mean temperature was 20.3°C, a remarkable 3.1°C above average
   • At New Zealand climate stations over the past six years, for every record or near-record low monthly mean temperature there have been 12 record or near-record highs.
   • A hot March this year – higher temperatures than what it’s usually like in mid to late summer.
   • Marine heatwaves over the past two summers – likely a contributor to this week’s wettest 48 hours on record.
   • A near record 40-day dry spell in Nelson this summer which included significant wildfires.
   • 2018 coming in at NZ’s equal-second warmest year on record .” [High-res graph available here under creative commons (CC BY-NC-ND 4.0)].

   Professor Jim Salinger, Visiting Scholar, Penn State University, comments:
   “The 25th Anniversary issue shows hastening climate warming globally. This was true for the New Zealand region, a combined land and marine area of 4 million sq. km (the size of the Indian subcontinent), with the warmest year on 150 years of land and sea records.
   “It is very alarming that the carbon dioxide levels reaching a highest 406 ppm – up from 280 ppm in the 19th century, and methane jumping unexpectedly by 25 ppb to a record 1850 ppb by 2017.
   “The extra 3.7 mm of sea level rise will be very significant for the coast of Australia, and especially New Zealand with its many seaside urban areas and long coasts.
   “The record warm summer ending in February 2019 produced the largest ice loss on the Southern Alps glaciers since the regular end of summer snowline surveys started 42 years ago.
   “We’ve seen Queensland Groper in the Bay of Islands, Northland, 3000 km out of range, snapper in Milford Sound in Fiordland, and massive mortality in the aquaculture fisheries of the Marlborough Sounds. These are a harbinger of climate in the latter part of the 20th century if we do not take action to reduce emissions from the combustion of fossil fuels and the production of greenhouse gases from other sources such as waste and agriculture immediately.”

2. A dilemma ‘the left’ in New Zealand faces:

   Diversity is generally good, but do we all embrace the diversity we have, and do we show tolerance towards others, at all levels of society?

   The law must be respected, that is the only basic rule as I understand it, all else has to adjust to it.
