Italy – Severe floods continue to impact areas in southern Italy, with videos posted to social media showing floodwater swirling through streets. Extreme threat warnings for flash flooding in southern Italy are in place until October 6. Currently major flash flooding can be seen in Catania, Sicily and in Pulsano (Ta), Puglia, south Italy this morning. Churning in the skies above Italy is a V-shaped mesoscale convective system (MCS) causing intense storms and torrential rainfall onto the Calabria and Puglia regions.

Costa Rica – Heavy rains over the course of the week caused significant flooding throughout Costa Rica on Friday. Nearly 1,000 people have been evacuated to at least 16 different shelter sites due to overflowing rivers in the provinces of Puntarenas and Guanacaste.

Global Warming

The Next Three Months are Crucial for the Future of the Planet

The warning signals of climate change that have hit people around the world in the last few months must be heeded by national governments at key meetings later this year, political leaders and policy experts are urging, as the disruption from record-breaking weather continues in many regions.

Extreme weather events have struck around the world – from the drought and record temperatures in northern Europe, to forest fires in the US, to heatwaves and drought in China, to an unusually strong monsoon that has devastated large areas of southern India.

As the northern hemisphere summer closes, polar observations have just established that the Arctic sea ice narrowly missed a record low this year. The sea ice extent was tied for the sixth lowest on record with 2008 and 2010. Sea currents and wind conditions can have large effects on sea ice extent from year to year, but the trend is starkly evident. Of particular concern is the decline in thick ice which forms over several years. “The older ice has been replaced by more and more first-year ice, which is easier to melt out each summer.

Not all of the effects of this year’s extraordinary weather, which has also seen the UK’s joint hottest summer on record, can be traced directly to climate change. However, scientists are clear that the background of a warming planet has made extremes of temperature, and accompanying droughts and floods, more likely.

This week, scientists are gathering in South Korea to draw together the last five years of advances in climate science to answer key questions for policymakers.

After the Korean IPCC publication, the world will face a key test of faith in the 2015 Paris agreement, the only global pact stipulating action on temperature rises. This December in Poland, the UN’s climate change arm will hold a two-week meeting aimed at turning the political resolve reached in Paris three years ago into a set of rules for countries to follow on reducing emissions.

The political situation is more fraught than it was in the runup to Paris. The US is pulling out of the landmark climate agreement and is likely to play little part in the talks. Australia’s government is also in turmoil over climate actions. Now the challenger for Brazil’s presidency, Jair Bolsonaro, is threatening to withdraw its participation – a potential blow to the Paris consensus, as Brazil was a linchpin among rapidly developing nations.

All eyes will be on China, which has shown remarkable progress on renewable energy and emissions reduction, and India, where climate champions have found common cause with opponents of increasingly damaging air pollution.

Disease

Cholera – Niger – Update

Niger health officials reported the first cases of this most recent cholera outbreak in early July, and since that time, the outbreak has ballooned to thousands of cases that have spread to multiple regions of the country. As of 1 October 2018, 3692 cases (14% of these were cases in Nigerian residents seeking care in Niger) with 68 deaths (case fatality rate = 1.8%) have been reported from twelve health districts in four regions: Dosso, Maradi, Tahoua, and Zinder.

Monkeypox – Nigeria

On 26 September 2017, WHO was alerted to a suspected outbreak of monkeypox in Yenagoa Local Government Area (LGA) in Bayelsa State, Nigeria. The index cluster was reported in a family. All of whom developed similar symptoms of fever and generalized skin rash over a period of four weeks. Epidemiological investigations into the cluster show that all infected cases had a contact with monkey about a month prior to onset.
