The group unfurled a banner that read “No Prison Ships” and tried to halt the coach of migrants.

They managed to temporarily halt the coach, which had around 30 migrants on board.

The vehicle moved forward as the protesters pushed back against it before sitting down on the tarmac.

Just Stop Oil said the group were “repeatedly driven into, resulting in them leaving the carriageway for their own safety.”

Two people were arrested.

LONDON, Oct 19 (Reuters) – Britain’s decision to authorise new licences for oil and gas exploration in the North Sea was lawful, London’s High Court ruled on Thursday, dismissing a legal challenge by Greenpeace.

The environmental campaign group had argued Britain’s failure to assess the greenhouse gases produced by consuming oil and gas – so-called end-use or downstream emissions – rendered its offshore energy plan unlawful.

But lawyers representing Britain’s Department for Energy Security and Net Zero said at a hearing in July that ministers were not required to assess end-use emissions, though they nonetheless considered them.

Judge David Holgate rejected Greenpeace’s case on Thursday, saying in a written ruling that the decision not to assess end-use emissions was not irrational.

Greenpeace said it planned to appeal the ruling.

There has been widespread bewilderment and anger after former Prime Minister Boris Johnson, who has a history of lying and who trashed Parliament, was appointed as a ‘democracy adviser’.

Johnson, who was booted out of office after lying about Covid lockdown parties in Downing Street, trashing the very rules his own government had set, and who prorogued parliament, violated parliamentary codes, lied repeatedly, partied in lockdown and handed government contracts to Tory cronies, has been appointed to the advisory board of the International Democracy Union (IDU).

The IDU is a global centre-right group chaired by Stephen Harper, the former prime minister of Canada, whose stated goal is the promotion of “democracy and centre-right policies around the globe”.

On Tuesday the group announced: “The IDU is excited to announce that PM Boris Johnson has joined our Honorary Advisory Board”.

More than 200 scientists from 19 countries want to tell us the Southern Ocean is in trouble

While the Southern Ocean around Antarctica has been warming for decades, the annual extent of winter sea ice seemed relatively stable – compared to the Arctic. In some areas Antarctic sea ice was even increasing.

That was until 2016, when everything changed. The annual extent of winter sea ice stopped increasing. Now we have had two years of record lows.

In 2018 the international scientific community agreed to produce the first marine ecosystem assessment for the Southern Ocean. We modelled the assessment process on a working group of the Intergovernmental Panel on Climate Change (IPCC). So the resulting “summary for policymakers” being released today is like an IPCC report for the Southern Ocean.

This report can now be used to guide decision-making for the protection and conservation of this vital region and the diversity of life it contains.

Why should we care about sea ice?

Sea ice is to life in the Southern Ocean as soil is to a forest. It is the foundation for Antarctic marine ecosystems.

Less sea ice is a danger to all wildlife – from krill to emperor penguins and whales.

The sea ice zone provides essential food and safe-keeping to young Antarctic krill and small fish, and seeds the expansive growth of phytoplankton in spring, nourishing the entire food web. It is a platform upon which penguins breed, seals rest, and around which whales feed.

The international bodies that manage Antarctica and the Southern Ocean under the Antarctic Treaty System urgently need better information on marine ecosystems. Our report helps fill this gap by systematically identifying options for managers to maximise the resilience of Southern Ocean ecosystems in a changing world.

An open and collaborative process

We sought input from a wide range of people across the entire Southern Ocean science community.

We sought to answer questions about the state of the whole Southern Ocean system – with an eye on the past, present and future.

Our team comprised 205 authors from 19 countries. They authored 24 peer-reviewed papers. We then distilled the findings from these papers into our summmary for policymakers.

We deliberately modelled the multi-disciplinary assessment process on a working group of the IPCC to distill the science into an easy-to-read and concise narrative for politicians and the general public alike. It provides a community assessment of levels of certainty around what we know.

We hope this “sea change” summary sets a new benchmark for translating marine research into policy responses.

So what’s in the report?

Southern Ocean habitats, from the ice at the surface to the bottom of the deep sea, are changing. The warming of the ocean, decline in sea ice, melting of glaciers, collapse of ice shelves, changes in acidity, and direct human activities such as fishing, are all impacting different parts of the ocean and their inhabitants.

These organisms, from microscopic plants to whales, face a changing and challenging future. Important foundation species such as Antarctic krill are likely to decline with consequences for the whole ecosystem.

The assessment stresses climate change is the most significant driver of species and ecosystem change in the Southern Ocean and coastal Antarctica. It calls for urgent action to curb global heating and ocean acidification.

It reveals an urgent need for international investment in sustained, year-round and ocean-wide scientific assessment and observations of the health of the ocean.

We also need to develop better integrated models of how individual changes in species along with human impacts will translate to system-level change in the different food webs, communities and species.

What’s next?

Our report will be tabled at this week’s international meeting of the Commission for the Conservation of Antarctic Marine Living Resources in Hobart.

The commission is the international body responsible for the conservation of marine ecosystems in the Southern Ocean, with membership of 26 nations and the European Union.

It is but one of the bodies our new report can assist. Currently assessments of change in habitats, species and food webs in the Southern Ocean are compiled separately for at least ten different international organisations or processes.

The Southern Ocean is a crucial life-support system, not just for Antarctica but for the entire planet. So many other bodies will need the information we produced for decision-making in this critical decade for action on climate, including the IPCC itself.

Beyond the science, the assessment team has delivered important lessons about how coordinated, collaborative and consultative approaches can deliver ecosystem information into policymaking. Our first assessment has taken five years, but this is just the beginning. Now we’re up and running, we can continue to support evidence-based conservation of Southern Ocean ecosystems into the future. The Conversation

Drought in the Amazon: Understanding the causes and the need for an immediate action plan to save the biome

The drought plaguing the Amazon is a worrying portrait of the climate challenges facing the world. The combination of the El Niño phenomenon and anthropogenic climate change has played a significant role in accentuating this extreme weather event. The Amazon region, known for its lush rainforest and flowing rivers, is facing a critical situation due to a lack of rainfall and rising temperatures.

This phenomenon, never recorded at this intensity, has affected biodiversity and human life in eight Amazonian states. The drought has already killed more than 140 dolphins, including pink dolphins and tucuxis, also known as grey dolphins. The mortality of fish and other aquatic animals is also high. The low volume of the rivers affects the human supply, causing a lack of drinking water and food in all the small villages, even those located on the banks of the big rivers. Of the 62 municipalities in the state of Amazonas, 42 are in a state of emergency, 18 are in a state of alert and only two are in a normal situation.

The El Niño phenomenon has a direct influence on the Amazon drought. It manifests itself in the abnormal warming of the surface waters of the Pacific Ocean, affecting the rainfall regime in various parts of the world. In the case of the Amazon region, the drought is exacerbated by a decrease in humidity and a lack of rainfall, damaging the vegetation, fauna and local communities that depend on natural resources.

However, anthropogenic climate change is making the situation even worse. Rampant deforestation, driven by agricultural expansion and logging activity, reduces the Amazon rainforest’s ability to regulate the climate and retain moisture. In addition, the destruction of vast areas of vegetation contributes to rising temperatures, creating a cycle of even more accentuated droughts.

Deforestation and mining, major factors

Deforestation has been particularly devastating in the region of Highway BR-319, in the south of Amazonas state, driven by land grabbing which has provided cheap land to cattle ranchers from other states. In turn, this deforestation has increased the number of fires that feed back into the climate crisis. When they occur near riverbanks, deforestation also intensifies the phenomenon known as fallen land, which has drastically affected the draught of rivers and is already significantly jeopardising navigation and logistics, mainly affecting villages in the interior of the Amazon, which are already suffering from shortages.

Another factor that has played a significant role in affecting navigation is mining activity. Disorganised mineral extraction has created banks of land that are harmful to navigation and which, in the critical scenario of drought, have caused many vessels to run aground.

The impact of hydroelectric dams

Hydroelectric dams also play a role in contributing to the drought scenario, especially on the Madeira River. This is mainly due to the decomposition of organic matter in reservoirs created by dams, which releases methane, a potent greenhouse gas, into the atmosphere. In addition, deforestation associated with the construction of dams, as well as soil degradation and erosion resulting from the alteration of aquatic and terrestrial ecosystems, can increase emissions of carbon dioxide (CO2) and other pollutants, contributing to the impact of hydroelectric dams on climate change.

The Madeira River, now at its lowest level in almost 60 years, has been drastically affected and transformed by the Jirau and Santo Antônio hydroelectric dams. This was due to the drastic alteration of the river’s natural flow caused by the damming of water for power generation. When water is dammed, a reservoir is formed that retains part of the water that would normally flow along the river. This diversion of the flow directly affects the region’s aquatic and terrestrial ecosystems, since the basin’s hydrological cycle is interrupted. The reduction in the volume of water in the Madeira River, for example, can lead to prolonged periods of drought, affecting not only aquatic fauna and riparian habitats, but also local communities that depend on the river for their livelihoods.

In addition, the construction and operation of hydroelectric dams in the Amazon often involves the clearing of significant areas of forest for the construction of dams and associated infrastructure. Deforestation contributes to a reduction in evapotranspiration, which is a crucial process for water balance in the region. With fewer trees to release water into the atmosphere, the Amazon becomes more susceptible to drought. The combination of these factors results in a significant impact on the region, making hydroelectric dams one of the causes of drought in the Amazon, particularly on the Madeira River, with worrying environmental and social consequences.

What can still be done

In order to combat the extreme drought in the Amazon and its devastating effects, it is essential to adopt strict measures to curb deforestation and illegal mining in the region, and for the federal government to review major undertakings such as hydroelectric dams and roads, such as the BR-319 motorway.

Many politicians have argued that the road, if paved, could reduce the state’s isolation, especially during droughts. However, this is a fallacious argument, because connecting the most isolated municipalities would require hundreds of kilometres of side roads, which would further increase deforestation and aggravate the climate crisis.

In addition, the BR-319 motorway has become a spearhead that cuts through one of the most conserved blocks of forest, linking the central Amazon, which is still preserved, to the “arc of Amazonian deforestation”, a region that concentrates most of the climate anomalies in the entire biome.

Ecosystem on the edge

In a recent study published in the renowned journal Conservation Biology, it was shown that deforestation in the Amazon is already impacting ecosystem services that are essential for Brazil, such as the Amazon’s flying rivers. This scientific data shows that we are already at the threshold of deforestation and environmental degradation tolerated by the Amazon, and more forceful action needs to be taken now.

Part of this responsibility lies now in the hands of President Lula, in reviewing major developments in the Amazon, such as hydroelectric dams and highways like the BR-319. In addition, it is essential to institute a zero deforestation policy that should begin this year, and not in 2030, when it will be too late. Furthermore, it is crucial that the international community and local governments work together to reduce greenhouse gas emissions and tackle climate change effectively. Only with coordinated and decisive action will we be able to mitigate the impacts of drought in the Amazon and protect this unique ecosystem that plays a vital role in regulating the global climate.The Conversation
