'Alarming' extinction threat to Europe's trees

The conservation status of most animals in Europe has already been assessed for the inventory of endangered species known as the Red List.

Experts are now turning their attention to plants, with an assessment of all 454 tree species native to the continent.

The report found:

  • 42% are threatened with extinction (assessed as Vulnerable, Endangered or Critically Endangered)
  • Among endemic trees - those that don't exist anywhere else on Earth - 58% are threatened.

"This report has shown how dire the situation is for many overlooked, undervalued species that form the backbone of Europe's ecosystems and contribute to a healthy planet."

Recommendations included further research into the impact of climate change.

Mike Seddon, chief executive of Forestry England said the "climate crisis" was a real threat to woodlands, including the nation's forest they manage, increasing the risk from pests and diseases.

"Our efforts to have resilient forests include planting a greater variety of trees, including native species, only grown in the UK," he said.

 

entretanto em Portugal, o ministro do ambiente não quer saber de conservar a diversidade florestal:

O Ministro do Ambiente, Matos Fernandes, fez publicar a Portaria 58/2019, que determina que no "PARQUE NACIONAL DA PENEDA-GERÊS", DEVE SER PRIVILEGIADA A ESPÉCIE florestal EUCALIPTO (Artigo 36º). (Paulo de Morais)

Greta Thunberg mostra-se perplexa com “fomentadores de ódio” que a atacam

A activista sueca tem recebido várias críticas ao longo desta semana e responde: “Honestamente, não percebo por que é que há adultos que escolhem passar o seu tempo a gozar e ameaçar crianças e adolescentes”.

“Criticam-me, a minha aparência, a minha roupa, o meu comportamento e a minha diferença”.

 

Há uma grande quantidade de negacionistas que criticam e até gozam com a rapariga por ter síndrome de Asperger. Se Greta Thunberg fosse um rapaz, a síndrome dela seria falada como um sintoma ou uma causa explicadora da sua precocidade e inteligência. Como é uma rapariga, é só uma anormal...

Até há relativamente poucos anos as raparigas com síndrome de Asperger ou autismo não eram diagnosticadas como tal e ficavam sem tratamento porque se pensava que, dado as pessoas com essas condições serem por regra muito inteligentes, as raparigas não podiam, naturalmente, sofrer delas.

Cientistas reunidos em Coimbra enviam “mensagem forte” sobre alterações climáticas aos líderes mundiais

“Temos de fazer alguma coisa nestes dez anos, mas tem de ser de imediato”, disse à agência Lusa José Xavier, docente do Departamento de Ciências da Vida da Faculdade de Ciências e Tecnologia da Universidade de Coimbra (FCTUC), um dos coordenadores e o único português que integra o programa SCAR AnT-ER.

No âmbito do programa SCAR AnT-ERA, os académicos “avaliam os grandes desenvolvimentos científicos” neste domínio, procurando perceber em que medida e “quais os seres vivos que se vão adaptar e quais se vãos extinguir” devido às mudanças do clima na Terra.

Perante o degelo na Antártida, “temos de agir na próxima década, temos dez anos para ir a tempo”, alertou, frisando que os efeitos do aquecimento global “estão a acelerar de uma maneira tão grande”.

2019 - sinais de esperança

por beatriz j a, em 30.12.18

 

For example, in 2016, for the first time, the share of global energy that came from renewables passed 10%. According to the International Energy Agency, the world got nearly 25% of its electricity from renewables in 2017, and that number should jump to 30% within the next few years. (Note: Many of the figures cited in this story are from 2017 or 2016, but most were published in 2018 because it usually takes a year or two to gather and analyze global data.)

New data also show that, between 2016 and 2017, some 6.7 million additional sq km (2.6 million sq miles) of the world’s oceans were put under environmental protection. The majority of that is in national waters, meaning more countries are actively assisting in the global ocean conservation project. (About 260,000 sq km of land were also added.)

It’s a bit hard to contextualize how many endangered or threatened species we’ve been able to save, since their ranks grow as as humans explore more of the world and find new species we must assess. But the fact that we’ve been able to take an increasing number off these lists is encouraging. In 2018, the lesser long-nosed bat was delisted thanks largely to the efforts of tequila producers, whose agave plants the bats feed on.

Poverty/Income

It can be hard to assess global poverty rates, since context can vary dramatically. One way to look at it is by comparing the difference between what the average person makes a day, and the global poverty line of $1.90 a day (as determined by the World Bank). Based on that measure, global poverty is falling.

Another thing to consider is quality of life. Electricity is essential to health, education, and general satisfaction. According to new data released this year, 87% of people around the world had access to electricity in 2017.

Education

Literacy rates have been steadily climbing for decades now, and though it seems incremental, even a fraction of a percentage point can make a huge difference. Considering there are some 5.5 billion adults alive today, the 0.23 percentage-point increase from 2015 to 2016 (the last year for which data are available) means about 11.5 million more people can read.

Public health

Probably the biggest invisible improvements the world sees year to year are essential indicators of overall global public health, like rates of infant mortality, maternal mortality, childhood stunting, and teen pregnancy. These are important, because they represent access the average person alive has to health care professionals, facilities, medicine, and more. All of these rates have been falling in the past few decades, in some cases dramatically.

Another good indicator of improving global health is rates of treatable infectious diseases, like tuberculosis and malaria. These have typically been much bigger problems in poorer parts of the world, but those care gaps continue to close.

Gender equality & LGBT rights

Another positive trend that can fly under the radar, especially in wealthier countries, is how the global gender gap in education continues to close. New data published this year show that, in 2016, there were 99.7 girls enrolled in primary and secondary school for every 100 boys. For comparison, in 1986 that number was 85.1. As with some of these other indicators, each year sees only what appears to be incremental improvement, but given the size of the global population, those tiny increases have outsized impact.

The 2018 US elections resulted in a historic new class of congressional representatives: at least 121 women will serve in Congress starting next year, accounting for just under 23% of Congress members. That, though, just brings the US in line with the global trend, in which women’s share of government seats passed 23% in 2016, and rose to nearly 24% in 2017.

There’s still much to do for women’s equality. There’s also much more to do for LGBTQ rights. But one encouraging trend is that countries continue to legalize same-sex marriage. In 2018, Costa Rica’s highest court ruled that laws banning same-sex marriage are unconstitutional, bringing the country in line with about 30 others that have done the same.

BEFORE HURRICANE FLORENCE, REPUBLICAN LAWMAKERS IGNORED SCIENTISTS’ WARNINGS OF RISING SEA LEVELS IN NORTH CAROLINA

By Amanda Rohloff

Edited by André Saramago

 

 

In recent years, interest in climate change has rapidly increased in the social sciences and yet there is still relatively little published material in the field that seeks to understand the development of climate change as a perceived social problem. This book contributes to filling this gap by theoretically linking the study of the historical development of social perceptions about ‘nature’ and climate change with the figurational sociology of Norbert Elias and the study of moral panics.

 

By focusing sociological theory on climate change, this book situates the issue within the broader context of the development of ecological civilizing processes and comes to conceive of contemporary campaigns surrounding climate change as instances of moral panics/civilizing offensives with both civilizing and decivilizing effects. In the process, the author not only proposes a new approach to moral panics research, but makes a fundamental contribution to the development of figuration sociology and the understanding of how climate change has developed as a social problem, with significant implications regarding how to improve the efficacy of climate change campaigns.

 

This highly innovative study should be of interest to students and researchers working in the fields of sociology, environment and sustainability, media studies and political science.

Não fosse o facto de estar doente e não estar em condições de sair de casa, sequer, dia 14 não faltava à manisfestação. As alterações climáticas são um problema que só se resolve com políticas colectivas. Esforços individuais são importantes porque consciencializam da necessidade inadiável de políticas colectivas e pressionam os poderes políticos mas não resolvem um problema desta dimensão.

As imagens mais abaixo vêm da Indonésia. Um derrame de petróleo no mar matou 5 pessoas em 31 Março passado e está a alastrar. Centenas de pessoas com dificuldades respiratórias, náuseas e vómitos por causa do cheiro e do fumo negro. Destruiu habitats marinhos e florestas de manga. O derrame põe em perigo ecossistemas, a economia e o sustento dos pescadores e subsidiárias locais.

Como é que se pode querer começar em Portugal uma coisa destas?

Climate change is a disaster foretold, just like the first world war

 

According to the World Wildlife Fund’s 2016 Living Planet Report, over the last four decades the international animal population was reduced by nearly 60%. More than a billion fewer birds inhabit North America today compared to 40 years ago. In Britain, certain iconic species (grey partridges, tree sparrows, etc) have fallen by 90%. In Germany, flying insects have declined by 76% over the past 27 years. Almost half of Borneo’s orangutans died or were removed between 1999 and 2015. Elephant numbers have dropped by 62% in a decade, with on average one adult killed by poachers every 15 minutes.

We inherited a planet of beauty and wonders – and we’re saying goodbye to all that.

 

In February, for instance, scientists recorded temperatures 35 degrees above the historical average in Siberia, a phenomenon that apparently corresponded with the unprecedented cold snap across Europe.

... eight million tons of plastics are washed into the ocean each year.

 

It can’t be so bad, we think: if a natural wonder were truly under threat, our politicians wouldn’t simply stand aside and watch.

The first world war killed 20 million people and maimed 21 million others. It shattered the economy of Europe, displaced entire populations, and set in train events that culminated, scarcely two decades later, with another, even more apocalyptic slaughter.

And it, too, was a disaster foretold, a widely-anticipated cataclysm that proceeded more-on-less schedule despite regular warnings about what was to come.

...

As early as 1898, Tsar Nicholas II of Russia initiated a conference to discuss international arbitration and limit the arms race taking place in Europe.

Over the next years, the rivalries intensified, leading to further militarisation and a complex series of (often secret) treaties, as, between 1908 and 1913, the military spending of the major powers increased by 50%.

...

The appeals to humanity and reason did not move states jostling for trade and commercial advantages. For the people of Europe, the arms race was disastrous; for specific governments, it made perfect sense, for those who did not compete risked falling behind.

The same might be said today.

If we don’t sell coal, says Malcolm Turnbull, our competitors will – which was, of course precisely the logic of the British fleet expansion in 1908.

The devastation of the first world war eventually engendered a wave of revolt from a populace appalled at the carnage their politicians had wrought.

From a global perspective, the necessity to abandon fossil fuels cannot be denied. But for individual economies, change risks undermining comparative advantages.

 

The stakes could not be higher. Lamps are going out all over the natural world … and no one will ever see them lit again.

Climate change to cause humid heatwaves that will kill even healthy people

The new analysis assesses the impact of climate change on the deadly combination of heat and humidity, measured as the “wet bulb” temperature (WBT). Once this reaches 35C, the human body cannot cool itself by sweating and even fit people sitting in the shade will die within six hours.

The revelations show the most severe impacts of global warming may strike those nations, such as India, whose carbon emissions are still rising as they lift millions of people out of poverty.

(...)

The limit of survivability, at 35C WBT, was almost reached in Bandar Mahshahr in Iran in July 2015, where 46C heat combined with 50% humidity. “This suggests the threshold may be breached sooner than projected,” said the researchers.
