The world is facing a clear and existential threat - a climate emergency. That's the stark warning by a global group of 11,000 scientists.

They say the climate crisis is accelerating faster than most scientists expected. It's closely linked to wealthy lifestyles and excessive consumption.

Their report gives simple and immediate steps that could make a difference. They recommend people must eat less meat, emissions must be cut and fossil fuels replaced.

Without action, they warn, large areas of Earth could become uninhabitable.

But scientists say there is hope and the global protest movement can bring change.

So, will governments and world leaders listen to these latest warnings?

India's top court says the capital is choking every year and blames state government for failing to curb pollution.

A car-rationing system has been launched, but the Supreme court considers it a 'gimmick' and wants firm action to address the problem.

Pollution is so high that schools have been shut, flights diverted and a public health emergency declared.

Some experts say breathing the city's air is as bad as smoking 50 cigarettes a day.

And that's not just in the capital. The World Health Organization says 13 other Indian cities are among the world's 15 most polluted.

But what's being done to tackle it?

Saudi Arabia's crown jewel and the world's largest oil producing firm, Aramco, is now set to go public after several delays.

The initial public offering, or IPO, will be on the Saudi stock exchange. How much of the company's for sale and at what price, will be determined later.

Part of the Crown Prince's economic plans for the kingdom, the flotation aims to raise billions of dollars.

But estimates of how much it might actually draw, vary widely.

Mohammed Bin Salman wants a $2 trillion price tag, many bankers put it at $1.5 trillion.

But can ARAMCO's IPO satisfy his ambitions?

And what, if any, are the risks?

New threats are emerging in the so-called 'global war on terror'.

That's the warning from the US State Department as it released its latest country reports on terrorism.

It named Iran as the world's worst state sponsor of terrorism.

ISIL remains a threat, despite last week's death of founder Abu Bakr Al Baghdadi in a US military raid in Syria.

The State Department is also concerned about the rise of attacks inspired by white supremacy and racist ideology.

So what are the solutions?

In only the fourth time in US history, The House of Representatives has formalised impeachment proceedings against a sitting president.

Public hearings will begin later this month after weeks of testimonies behind closed doors.

At the centre of the investigation is whether President Donald Trump abused his power and jeopardised national security by withholding US military aid from Ukraine in exchange for an investigation into his political rival, Joe Biden.

Trump has repeatedly denied doing anything wrong, and the White House is refusing to cooperate.

So what happens next?

And what will be the impact on next year's elections?

Following mass march and violent protests, government leaders in Madrid are dismissing Catalan calls for talks.

It's been two years since Catalonia tried - and failed to break away from Spain, but the campaign for independence hasn't died.

The jailing of separatist leaders this week re-ignited the debate, sparking a mass march from all over Catalonia to Barcelona.

And violent protests in the regional capital have raised questions about the reaction from Spain's government in Madrid - especially before next month's national election.

The region's pro-independence leader Quim Torra, has called for unconditional talks with the Spanish government

But Prime minister Pedro Sanchez has dismissed the calls saying Torra must first unequivocally condemn the unrest

So What are the chances for a political solution?

Lebanese people from all religious and political backgrounds are calling for the Prime Minister, President and other leaders to resign.

They say they want a revolution, many criticising their own political leaders - something unprecedented in a country divided by sectarianism.

Two days and nights of the largest protests in years were sparked by tax reforms - including charging to use the social media service Whats App.

That plan was quickly scrapped but there are other, longstanding grievances.

They include high unemployment, constant electricity shortages, poor infrastructure and corruption.

The protests are a challenge to the unity government and Prime Minister Saad Hariri.

He's blaming parties in his coalition for obstructing reforms required to unlock $11 billion in aid pledged by international donors.

Are there hopes for meaningful political and economic change?

Diseases that were once eliminated are back.

Preventable illnesses such as measles are spreading, especially in Europe and North America.

The World Health Organization and the European Commission joined forces to tackle the issue at the first global vaccination summit.

The WHO estimates nearly 20 million infants were not immunised last year.

Although many of them live in developing countries with poor access to vaccines, scientists are worried that anti-vaccination campaigners in the developed world are spreading misinformation on social media.

So what's the cure for their scepticism?

A huge stash of weapons is found in Italy with neo-Nazi sympathisers and the government says the seizure is unprecedented.

An arsenal of weapons has been seized by Italian police in a raid on a far-right group.

The stockpile was discovered during an investigation into the involvement of Italy's far-right movement in the conflict in eastern Ukraine.

And it included an air-to-air missile, rocket launchers and automatic rifles described as 'latest generation'. Neo-nazi propaganda material was also seized.

Police have arrested three people, including a former candidate for the neo-fascist Forza Nuova party. Fabio Del Bergiolo's house was found to contain a huge stash of arms, as well as Hitler memorabilia.

So, how significant is this?

And what does it tell us about the re-emergence of Nazism and the far-right movement in Europe?
