For much of the last 30 years, the rest of the world has been forced to persevere with climate action in the face of US intransigence

• Outrage as Trump withdraws from key UN climate treaty along with dozens of international organisations

Donald Trump’s latest attack on climate action takes place amid rapidly rising temperatures, rising sea levels, still-rising greenhouse gas emissions, burgeoning costs from extreme weather and the imminent danger that the world will trigger “tipping points” in the climate system that will lead to catastrophic and irreversible changes.

The US president’s decision to withdraw from the UN Framework Convention on Climate Change (UNFCCC) and the world’s leading body of climate scientists, the Intergovernmental Panel on Climate Change, will not alter any of those scientific realities.

Advocates suing to reverse administration’s surcharge system that has led to passport checks and angry visitors

A new $100 fee for foreign tourists entering US national parks has triggered chaos and frustrating waits, with staff reporting long entry lines as citizenship checks are made and irate visitors regularly ditching plans to patronize some of America’s most cherished landscapes.

The new fee system, introduced by the Trump administration from 1 January, has caught many visitors and National Park Service (NPS) staff off-guard, with checks now having to be undertaken to assess nationality and tourists often turning away from entrances rather than pay the surcharge. The Guardian heard accounts of problems from several NPS staff, speaking anonymously, who work at different parks across the country.

Experts decry move to leave UNFCCC as ‘embarrassing’ as president orders withdrawal from 66 international groups

Donald Trump has sparked outrage by announcing the US will exit the foundational international agreement to address the climate crisis, cementing the US’s utter isolation from the global effort to confront dangerously escalating temperatures.

In a presidential memorandum issued on Wednesday, Trump withdrew from the UN Framework Convention on Climate Change (UNFCCC), along with 65 other organizations, agencies and commissions, calling them “contrary to the interests of the United States”.

‘Everybody loses’ if production supercharged in country with largest known oil reserves, critics say

Donald Trump, by dramatically seizing Nicolás Maduro and claiming dominion over Venezuela’s vast oil reserves, has taken his “drill, baby, drill” mantra global. Achieving the president’s dream of supercharging the country’s oil production would be financially challenging – and if fulfilled, would be “terrible for the climate”, experts say.

Trump has aggressively sought to boost oil and gas production within the US. Now, after the capture and arrest of Maduro and his wife, Cilia Flores, he is seeking to orchestrate a ramp-up of drilling in Venezuela, which has the largest known reserves of oil in the world – equivalent to about 300bn barrels, according to research firm the Energy Institute.
