A new climate report warns that countries must commit to becoming net zero emitters of greenhouse gas emissions before 2050, and that decisions made today are critical for ensuring a safe, sustainable future. Rapid, unprecedented, and far-reaching action across all aspects of society is urgently required to limit global warming to 1.5 °C, the latest Intergovernmental Panel on Climate Change report on climate change has concluded.

The Earth may be well on its way to an irreversible “hothouse” if people do not take urgent collective action to steer its path to a habitable state, scientists warned. According to a recent study Trajectories of the Earth System in the Anthropocene published by the Proceedings of the National Academy of Sciences of the United States of America (PNAS),even if the target 1.5 degrees C to 2.0 degrees C rise in temperature under the Paris Accord is met, “a domino-like cascade” of biogeophysical feedbacks including the melting of polar ice, forest diebacks, and increased bacterial respiration in the ocean, coupled by annual greenhouse gas emissions “could take the Earth System to even higher temperatures.” “Hothouse” is a term used to describe a “likely uncontrollable and dangerous” condition where global average temperatures could spike by 4 to 5 degrees C and sea levels could rise up to 60 meters higher than today, once the cascade of feedbacks causes the Earth to pass a tipping point.
Este año ha sido especialmente marcado por fenómenos climáticos extremos en diversos lugares del mundo. En el Perú, El Niño Costero produjo pérdidas de vidas y daños sociales y materiales en trece regiones. Si bien históricamente las poblaciones han sufrido numerosas veces los efectos de huracanes, inundaciones o huaycos -y éstos tienen causas naturales específicas- hoy se caracterizan por su mayor frecuencia, intensidad e impredictibilidad. Ello se debe al Calentamiento Global (CG) y el Cambio Climático (CC) en curso, originados por la actividad humana generadora de excesivas emisiones de gases de efecto invernadero en la atmósfera.
Pressão pró-desmatamento e barganhas políticas comprometem metas brasileiras de emissão de gás carbônico. Entrevista especial com Raoni Rajão
Apesar de a política brasileira de combate ao desmatamento ter sido aprimorada nos últimos anos, um estudo recente realizado por pesquisadores da Universidade Federal do Rio de Janeiro – UFRJ, da Universidade Federal de Minas Gerais – UFMG e da Universidade de Brasília – UnB demonstra que as barganhas concedidas pelo Estado brasileiro até 2016 podem reverter os índices de desmatamento no país e comprometer a meta brasileira de redução das emissões de gás carbônico assumidas no Acordo de Paris.
Interview with Miguel Arias Cañete, Commissioner for Climate Action, a few months ahead of the COP24 meeting in Katowice. There has been a lot of talks about the last COP23 meeting in Bonn. Regarding the Paris agreement, many issues remained unsaid. What are the main concerns for the European Union? The last COP in Bonn was particularly difficult because it was the first meeting following President Donald Trump’s announcement of his intention to abandon the Paris Agreement. However, it was also a good opportunity to confirm the commitment of the rest of the countries to the Agreement and their willingness to move forward with its implementation as soon as possible.
With World Environment Day falling this week (June 5) and World Oceans Day on June 8, there is little need for ever more ferocious storms, forest fires and flooding to remind us of the planet’s vulnerability in the face of increasing carbon in the atmosphere. A new report from a group of scientists in China suggests the Paris Agreement’s 2°C increase in the earth’s temperature on pre-industrial levels will soon be swamped with projections it will rise to double this figure before the end of the 21st century.
