150 and the New Zealand academics have written to the government an open letter calling for courage to react to climate change.
The letter says it is unacceptable that future generations will have to bear "the terrible effects of atmospheric leaks".
One of its authors, the University of Victoria professor James Renwick (James Renwick), said that worrying things were not moving faster.
"The science message has not really changed for 40 years. If the process started when the whole IPCC (Intergovernmental Panel on Climate Change) started in 1980, I do not think we could talk about this conversation today."
He said that speed should be similar to mobilization efforts during the war.
"[At the] At the start of World War II, governments could simply reorient their efforts to bear on their efforts to avoid what else was happening before, and the fact that we really needed a level of commitment and quick mobilization.
"We are talking about energy production, so that the whole world economy has changed significantly."
Professor Renwick said the New Zealand government was moving in the right direction and saying the right thing – it just had to travel faster.
"Many people and many policy makers do not appreciate the extent of the damage and the costs and losses that have arisen if we do not make a problem.
"It is a policy process and a debate that will continue in line with the United Nations Framework Convention on Climate Change, the Paris Agreement, and so on … every year there will be a yearly meeting, very soon, in 2020, when governments register on how they go. .
"It's all very well, but it's very clear that we need action as quickly as possible, and my point is an ordinary policy process that's just not fast enough," he said.
He said there were a number of changes that had been made and that could have been moved forward.
"Hundred percent of electricity from renewable energy sources, stimulating electric vehicles and public transport. In the last decade, New Zealand's emissions are mainly related to transport and industrial energy production, so they are areas where we have solutions, but changes could be made at an accelerated pace.
"In the agricultural sector, this is a more difficult problem, but we may want to change the combination of land use, possibly reducing the number of herds."
The letter referred to the recent IPCC report, which gave a firm message about the seriousness of the situation.
Scientists warn in a 12-year report that global emissions should be halved to avoid warming by more than 1.5 degrees.
"We know that if we allow it to exceed all risks of damage to ecosystems, there may be an increase in sea level rise, etc. There are some rather complicated consequences that are not as far away as now."
He said there would be a lot of advances, but New Zealand did not have the choice.
"Fire in California is a bit of a window for the future … the cost could be disastrous. I do not know how you can calculate the total burning of city values.
"The initial expenditure really is that it is precisely for the business sector and society as a whole that the right signals are being sent that it is definitely where we are to take a position and that we should try to do it very quickly."
He said when the direction was set, the economy would adapt.
"If you are a company that offers a better electric vehicle or a better solar panel it will be valuable, so it's not as if it were all."
While the letter was intended to rush through changes in government-level, he said that people could now begin to make changes.
"Eat less red meat by burning less fossil fuels without hurting the car, creating a little more flexibility in your community – talking to your neighbors – the more people who know it, the more people who can handle it.
"There are capacities in numbers."
