US President Joe Biden's Climate Envoy John Kerry assured Bangladesh of continued support and cooperation on tackling climate change impacts and Rohingya crisis as he called Foreign Minister AK Abdul Momen on Tuesday evening.

Kerry recognised the extraordinary challenges faced by Bangladesh due to climate change and frequent natural disasters, while stating that the next COP26 (UN conference on climate change) might be the world's last chance to hit the target of carbon emission.

He assured US' firm engagement to achieve the goal, said a foreign ministry statement yesterday.

The 2015 Paris Agreement aims to limit average global warming to 1.5-2 degrees Celsius this century relative to the 1890s (the so-called "preindustrial period").

Biden appointed Kerry his special envoy on climate and signed an executive order to rejoin the Paris Agreement. Immediate past president Donald Trump had withdrawn his country from the global deal.

However, US's return to the Paris Agreement generated high hopes of climate actions across the globe.

Momen recollected the vital contribution of Kerry towards the Paris Agreement and welcomed the decision of the US to return to the agreement.

Bangladesh is one of the most vulnerable countries in terms of climate change and there are predictions over 25 million people in the country's coastal areas could be displaced with a one-metre sea-level rise. Besides, extreme weather conditions will have devastating impact on life and livelihood.

During the telephone call that lasted about half an hour, Momen remembered the time-tested US-Bangladesh relations and expressed the satisfaction of Bangladesh government for the appointment of Kerry as US Presidential Envoy.

The foreign minister described all the actions taken by the Bangladesh under the leadership of Prime Minister Sheikh Hasina on mitigation, adaptation and measures to strengthen resilience.

He also briefed all the current and future actions of Climate Vulnerable Forum (CVF), whose chair is Bangladesh, and the Global Centre on Adaptation (GCA) Dhaka office.

Kerry conveyed his greetings to Hasina and agreed that the international financial institutions could do more for the issue of climate change.

He also opined that many countries were not responsible enough when it came to adequate mitigation and adaptation issues and their part of contribution.

Kerry also agreed with Momen that displacement due to climate change would be a vital security issue for everybody.

He emphasised on using the current opportunities to maximize inclusion of as many people as possible, and expressed his interest to be updated about the functions and priorities of the CVF and GCA.

Both of them agreed to work closely at COP26 to be held in the UK this November and other multilateral platforms.
