"Climate emergency" is an inappropriate phrase and should not be used, while humanitarian implications of climate change are summarised for humanitarian settlement and shelter in:

For concerns about climate change and disasters, see scientific papers:

Almost all the above issues are similar for around the world (whether Global North, Global South, Global East, Global West, or Global WNW among others), obviously with many aspects highly contextual--but not necessarily at the national level. For the UK over the next five years, you already pick the most important topic and, arguably, the only important topic: heat-humidity.

See the reports from https://www.lancetcountdown.org explaining how heat-related hazards are increasing in frequency, intensity, and duration due to human-caused climate change and will soon become a major killer through several pathways. There might be a concomitant decrease in cold-related hazards, yet the science is not yet entirely clear, apart from some locations such as across the Arctic. The decrease in cold-related impacts seems unlikely to offset the increase in heat-humidity-related impacts and this statement is almost certain for the UK.

I suggest you visit the IPCC website (https://www.ipcc.ch/) and download the Summary for Policymakers here:

1. Polar ice melting fast. People cannot travel over ice to go hunting /working

2. Greenland Ice melting too fast and causing sea level to rise

3. Permafrost melting releases tremendous amount of methane gas into the air (bubbles seen in lakes and swamps. If you collect gas, it burns with a flame)

4. Isolated communities in the North need ice roads to get supplies and groceries. If ice melts, their supplies will cost a lot to be sent by air.
