'Be the hero, not the villain': Protesting students wrote to Taoiseach urging him to take climate action

'Be the hero, not the villain': Protesting students wrote to Taoiseach urging him to take climate action Thousands of students attended climate change demonstrations across the country in March. Another student wrote to Varadkar on the day of the protest. They said: “Ireland has not been achieving the goals it has set for itself in the 2015 Paris agreement and if the government doesn’t take action now, we will continue to fail to meet our goals.” The student also pointed out the effects inaction would have on their peers into the future. “Our generation is the generation that will live in the ruins of the world created by the climate crisis and our governments are not doing anything about it,” they said.

Refreeze polar regions to reverse climate change, expert says © Getty Refreezing the polar regions could help reverse climate change A University of Cambridge professor has proposed a radical new centre for climate repair to reverse the damage humans are doing to the environment.

The proposals would aim to roll back the harms of global warming and include refreezing the Earth's polar regions and capturing carbon dioxide from out of the atmosphere.

Sir David, a former chief scientific adviser to the government, said that time "is no longer on our side" to tackle climate change.

"What we continue to do, what we do that is new, and what we plan to do over the next 10 to 12 years will determine the future of humanity for the next 10,000," he said.

Climate change is the most significant challenge we as a species face today. Now, to turn the tide back in our favor, scientists have theorized As a desperate bid to save Earth, the team wants to refreeze the Arctic.

Theoretical techniques of large-scale human intervention to drive climate change in a positive direction are part of an area of research known as geoengineering.

They could include spraying salt water high into the atmosphere in the Arctic to "whiten" clouds there and reflect heat back into space, as well as growing more vegetation to remove carbon dioxide from the air.

But the cost to research and implement these techniques safely has hampered most of these proposals.

Sky News' science correspondent Thomas Moore said: "Climate engineering has been discussed for many years.

"In the past it was considered too radical and potentially risked unforeseen effects on the environment, including changes in rainfall, and lower crop yields.

"But the anticipated risks of climate change have increased, so now many scientists are arguing that climate hacking should be back on the table - as an adjunct, not an alternative, to carbon cuts."

Unprecedented changes are required by society to prevent global temperatures rising more than 1.5 degrees Celsius according to the UN's intergovernmental panel on climate change.

The panel called for countries to cut carbon emissions by 45% by 2030 and to net zero by 2050, with steep cuts in other greenhouse gases such as methane also needed.

The UK recently went eight days without using any coal power after decades of investment in alternative energy sources.

There will be no electricity in the UK supplied by coal power at all by 2025, and the government believes the last coal plant in the UK could close as early as 2022 due to emissions charges.

Global warming expert warns Ireland is 'shrinking' due to erosion from climate change.
The Aran Islands off the Galway coast have already experienced the damaging effects . Chairman of the Aran Islands Energy co-operative Dara O Maoildhia said locals are worried about the changing landscape. Three years ago intense coastal erosion severely damaged main roads on Inishmore island. Mr O Maoildhia said: “There are two parallel roads that are the two main roads of the islands running from east to west. “The lower one is sea level and it was destroyed in probably three different places with huge chunks bitten out of it. It never happened before.
