The environment correspondent, Bonn.
Rich nations were accused of betraying the developing world at the end of the climate talks.
Poorer countries claim that they were promised that their key demand would be honoured this year.
They thought a new finance facility would be set up to pay for the impacts of climate change.
The issue has been sidelined by the US and Europe.
Loss and damage are the main issues in the global climate negotiations.
Climate impacts on developing countries are more severe than on richer countries, according to participants.
The Association La Ruta del Clima, a Costa Rican environmental group, has been damaged over the last 25 years.
"We have families who have lost their houses, their crops, their lives, and no one is paying for that, we are running out of resources, and at the same time, we are dependent on debt."
According to the developing nations, the climate change they are experiencing has been caused by carbon emissions from richer countries. The US and Europe have a responsibility to pay for the losses.
The US and Europe disagree. If they pay for historic emissions they could put their countries on the hook for billions of dollars for the rest of their lives.
There was a "delicate compromise" reached at the COP26 in Glasgow.
If the richer nations set up a process that would fund loss and damage, the island states and developing countries would agree to the Glasgow Climate Pact.
Alex Scott from E3G, an environmental think tank, said that the compromise was based on an understanding that countries would be willing to start talking.
We have not seen that happen here. We saw a workshop set up to discuss how we can fix some of the problems.
The first workshop meeting of the Glasgow dialogue on loss and damage took place in Bonn.
Poorer nations hoped that the technical meeting would put loss and damage on the agenda for the upcoming meeting of political leaders.
Several countries are opposed and that hasn't happened yet.
This would be a blow to unity if no progress is made.
Ambassador Conrod Hunte said it would be tragic.
What has been accomplished here? There is still a lot more to be achieved. Is it okay? I am not happy.
The climate campaign went further than the diplomats.
Rich countries are taking advantage of vulnerable nations. The EU, US and others are blocking progress on loss and damage finance.
The negotiations at Bonn are disappointing to us.
John Kerry, the US climate envoy, said at the beginning of the meeting that the world was "cooked" if carbon emissions weren't cut quickly.
Rachel Rose Jackson from Corporate Accountability said that global south countries are trying to get the US to pay for the harms they have caused.
The US cooks up delay after delay to avoid taking responsability for the climate crisis. The US is not cooked. The people are doing the cooking.
There is hope that a compromise can be found that will put loss and damage on the agenda for the meeting.
