Mr Hunt, the former environment minister, told Fairfax Media he has instructed CSIRO's executives and board to "put the focus back on climate science", adding: "This is not an optional component, it's critical".

The new strategy, to be devised over the next three months, includes 15 new climate science jobs and research investment worth $37 million over 10 years.

"I've issued a ministerial directive … that we will make climate science a core activity, that we will strengthen and build capacity," Mr Hunt said.

The 15 jobs would create a long-term platform for climate analysis and forecasting.

"This is emphasising the importance of long-term climate science as a bedrock function of the CSIRO … this is setting the direction for CSIRO for the coming two decades," Mr Hunt said.

Severe cuts to CSIRO programs announced in February, including massive proposed staff losses in climate change monitoring and modelling, prompted criticism that the organisation had succumbed to a right-wing agenda that Prime Minister Malcolm Turnbull assumed from Tony Abbott.

The government denied this, insisting the CSIRO was an independent statutory agency, which set its own priorities.

The CSIRO cuts came despite the agency's own projections last year showing Australia could be among the nations hardest hit by global warming at the end of this century.

Justifying the decision in February in an email to staff, CSIRO chief executive Larry Marshall said climate change has been established and the agency's focus should move to mitigation and adaptation.

Mr Hunt, who assumed the Industry, Innovation and Science portfolio from Christopher Pyne, said the fresh display of support for climate science was "a shared view of the Prime Minister … no question", and that the directive drew on Mr Hunt's previous environment role.

The new CSIRO strategy will be developed in consultation with the scientific community and Chief Scientist Alan Finkel.

When the CSIRO cuts were revealed, it was initially feared that the Oceans and Atmosphere division, which held the bulk of climate scientists, would lose most of its 140 staff.

However, this figure was whittled down to about 35 climate-science jobs across two key research programs. It is understood some voluntary redundancies have already been accepted.

The pared-back job losses came after sustained criticism, including from top NASA scientist Brent Holben, who said CSIRO risked undermining the world's ability to monitor and predict climate change.

Mr Hunt has met Dr Finkel, Dr Marshall and CSIRO chairman David Thodey to discuss the new direction.

"[Climate science] will be a priority and the senior executive and the board know this now, clearly," Mr Hunt said.

A new Climate Science Centre in Hobart, announced by the CSIRO in April, will form part of the new strategy.

Mr Hunt said he would not "outsource" the science role to his assistant minister Craig Laundy, and indicated he would soon release a significant science statement.

"I will be the minister for science … I want to be the chief science advocate in the government,' he said.

Speaking on ABC radio on Thursday, Mr Hunt rejected suggestions that Dr Marshall's position was now untenable, saying CSIRO had "embraced and endorsed" the new direction and Dr Marshall was "one of the outstanding science leaders, not just in Australia but around the world".

Asked if the directive indicated that the CSIRO was wrong to make cuts to climate science, Mr Hunt said the directive was "a decision that the Prime Minister and myself have taken. It's a new government and we're laying out a direction that climate science matters".

Mr Hunt said the government was "starting from where we are" when asked if CSIRO would reinstate climate scientists who had or would soon be made redundant.

He dismissed suggestions that CSIRO had suffered reputational damage.

"We have a great reputation as a nation in terms of science and as a nation in terms of climate science," Mr Hunt said.

He said the CSIRO's budget would increase by about $100 million over the next three years, and overall staffing levels will increase by more 200 "as opposed to where they were expected to be this year".

Dr Finkel said in February he only learned of the cuts when they were made public, and told Senate estimates that "Australia needs a continuous and highly effective commitment to climate science, both to meet our national needs and to fulfil our international commitments".

On Wednesday, he told Fairfax Media that "Australia needs a strong climate research capability".

"I welcome the Minister's support to strengthen Australian climate science capacity so we can respond to national and global challenges and inform our mitigation options," he said.

Greenpeace Australia Pacific senior climate and energy campaigner Nikola Casule said it was "preposterous" to axe climate science jobs at CSIRO and while the partial recovery of jobs was welcome, it did not go far enough.

"We hope this is the start of more positive leadership from the Turnbull government on the critical threat of climate change," he said.

"However, around 35 climate science jobs remain at risk, so restoring just 15 means the department is still under-resourced compared to earlier this year."

Mr Casule said 2015 was the hottest year on record, the Great Barrier Reef was suffering record coral bleaching and it was "vital that we have a functional and funded climate science program to help prevent the worst of the damage from dangerous global warming".
