the winter who just finished New Zealand It was the warmest ever, and scientists say climate change is continuing to raise temperatures.
In the three-month period ending in August, the average temperature was 9.8 degrees Celsius, according to New Zealand’s National Institute for Water and Atmospheric Research.
This is 1.3°C on average and 0.2°C higher than the previous record last year. Scientists have kept records since 1909, but Most of the winters have been the warmest in recent years.
Nava Vidaev, a meteorologist at the institute, noted that in addition to the context of Global WarmingThis year there were more warm winds from the north than usual, as well as warmer ocean temperatures.
He added that the warming trend can be traced through the concentration of carbon dioxide, which has increased in New Zealand from 320 parts per million 50 years ago to about 412 parts per million today.
Fedayev said lower-altitude snowfall has been well below average this year, and has often been replaced by rain, which could lead to lower river levels in the coming months due to less snow melt. This could affect agricultural irrigation, he said.
He added that there are more extreme weather phenomena, including severe floods In some areas, drought in others.
In the short term at least, some farmers with livestock or sheep could benefit from a longer grazing season, said Professor James Renwick, a climate specialist at Victoria University of Wellington.
But he also acknowledged that changes are putting pressure on natural ecosystems, and over time, more species will face extinction. confirmed it It is essential that humans reduce greenhouse gas emissions.
“If we don’t control warming soon, there will be pain in a large part of the world,” he said.
