What happened: The Democratic Republic of the Congo's health ministry counted 10,141 Ebola cases and nearly 5,000 deaths as of Oct. 26, UN News reported. The outbreak is caused by the Bundibugyo virus, for which there is no approved vaccine or treatment, and has spread to eight provinces. It is the largest of the DRC's 17 Ebola outbreaks and the second largest in the world after West Africa's in 2014-2016.

Why it matters: The outbreak began in the conflict-hit east amid hunger and displacement. More than 2,600 people have recovered, and a ring-vaccination trial called TUMAINI (Swahili for "hope") is testing whether an existing Ebola vaccine protects against this strain. Kenya has recorded nine cases, including two deaths.

How much agreement is there? Broad agreement. Health agencies agree on the threat; the WHO says ending it needs more access to affected areas and community outreach that builds trust.

Could someone help? Donors can back the aid groups and UN agencies working the response, and community health volunteers are central to the trust-building the WHO describes.

What happened: The Lancet Countdown report, produced with the World Health Organization and led by University College London, estimated a record 710,000 heat-related deaths worldwide in 2023, UN News reported on Oct. 28. For the first time, more than seven in 10 of those deaths were attributed to human-caused climate change. The report tracks 54 indicators linking climate and health.

Why it matters: It finds extreme drought affected 51.8% of the world's land for at least a month in 2025, and conditions for dengue spread by one mosquito species rose 24% since the 1980s. It also says the 100 largest oil and gas companies plan to produce 150% more fossil fuels by 2040 than a 1.5°C path allows.

How much agreement is there? Some disagreement. The health trends are drawn from many research groups; the debate is over response. The authors want climate change formally declared a global health emergency before the COP31 talks, and they also note a record $2.1 trillion in clean-energy investment last year.

Could someone help? Communities and young volunteers can check on older or isolated neighbors during heat waves, and health groups can push for the national health adaptation plans the report tracks.
