The opening game of the 2022 FIFA World Cup was one Ecuador fans will remember for years to come. For host nation Qatar, it's one they'll want to wipe from their memory before their next match against Senegal on Friday.

Here's what happened in the World Cup on Sunday and what to watch for tomorrow.

QATAR DISAPPOINTS IN WORLD CUP DEBUT AS EXCADOR’S ENNER VALENCIA SHINES IN OPENING MATCH VICTORY

Qatar became the first host nation to lose its opening match of the World Cup, as they fell to Ecuador 2-0. Host nations had 16 wins, six draws and no losses in their openers entering Sunday.

Qatar now has to get three points against the Netherlands or Senegal, which are ranked eighth and 18th in the world, respectively. 

Meanwhile, Ecuador gained three valuable points in a top-heavy group.

Even in a wide stance with his arms stretched out, Qatar goalkeeper Saad Al Sheeb couldn't stop Enner Valencia's perfectly-placed header from going in. It was Valencia's second of the day.

Before Valencia scored the World Cup-opening goal from the spot — and the eventual follow-up header — he scored what would have been the first of his hat trick. Had the goal stood, he would have been just the third player in World Cup history to score a hat trick on the opening day of the World Cup.

But the goal was wiped off when VAR review ruled the play offsides.

Things really get cooking Monday with three matches on the docket, including the opener for the United States.

England hasn't won an international match since March 29. That, combined with their history of disappointment on the World Cup stage, has led to many people tempering their expectations for a squad that, on paper, is among the most talented of the tournament. 

A convincing win against Iran — a team that's expected to have a strong fan presence — would turn some of the Three Lions' doubters into believers; a draw or a loss would only add more fuel to the fire.

Before a knee injury forced Sadio Mané to withdrawal from the tournament, the Senegal-Netherlands matchup was widely viewed as the tiebreaker for the top of Group B. While that might still end up being the case, the Netherlands has to feel better about their chances than they did at the start of the week.

If we’re to assume the best-case scenario for the United States against England is a draw, then a win against Wales is a necessity. Not only that, but history doesn’t bode well for teams that lose their group stage opener. Both teams will be looking for three points.

Representatives and negotiators from nearly 200 countries have reached a historic agreement to pay reparations to poor countries said to be victimized by climate change, though proponents say more is needed to scale back fossil fuels. 

The deal, gaveled around dawn in the Egyptian Red Sea resort city of Sharm El-Sheikh, established a fund for what negotiators call "loss and damage."

It was a big win for poorer nations that have long called for money — sometimes viewed as "reparations" — because they are often the victims of floods, droughts, heat waves, famines and storms despite having contributed little to the pollution that heats up the globe.

While the fund would be largely aimed at the most vulnerable nations, there would be room for middle-income countries severely battered by climate disasters to get aid.

Details of the fun have yet to be worked out. It will likely be a major topic at next year's climate conference in the United Arab Emirates in 2023. So far, only a few nations have made significant pledges for payments.

The fund would initially draw on contributions from developed countries and other private and public sources, such as international financial institutions. While major emerging economies such as China – the second-largest economy in the world and the top emitter – wouldn't automatically have to contribute, that option remains on the table. This was a key demand by the European Union and the United States. They argue that China and other large polluters currently classified as developing countries have the financial clout and responsibility to pay their way.

Environment officials in developing nations hailed Sunday’s development as an investment in the future and a "win for our entire world." Others, particularly EU officials, expressed disappointment that attendees failed to make more robust commitments to scaling back fossil fuels and cutting emissions. 

While the new agreement doesn't ratchet up calls for reducing emissions, it does retain language to keep alive the global goal of limiting warming to 2.7 degrees Fahrenheit. Next year's talks will also see further negotiations to work out details of the new loss and damage fund, as well as review the world's efforts to meet the goals of the Paris accord.
