Top story: Jump of 3.4% in carbon emissions is largest since 2010

Greenhouse gas emissions in the US rose sharply last year, as the Trump administration continued to roll back environmental regulations and stymied efforts to slow climate change. According to analysis from the economic firm Rhodium Group, carbon emissions rose by 3.4% in 2018, the biggest rise since the bounce back from recession in 2010 and the second largest annual gain in more than two decades, despite an ongoing shift from coal to natural gas-fired power.

Explosive warming. Scientists have calculated the shifting temperature of the oceans over the past 150 years and found global warming has heated the world’s waters by the equivalent of one atomic bomb explosion per second in that time.

Trump to make border wall speech on primetime TV

Donald Trump is planning to appear on primetime TV on Tuesday night to make the case for his planned border wall with Mexico. He will also visit the southern border this week, as the White House and Democrats in Congress remain split – and the federal government remains partially shut down – over how to address his demand for a border wall. Vice-president Mike Pence has said Trump is still contemplating whether to declare a national emergency to force through his plan for a wall, while White House lawyers review whether he has the power to do so.

Political impasse. Pence said on Monday that shutdown negotiations between Democrats and the White House over the weekend had been “productive”, but a Democratic aide told the Guardian no progress had been made.

DeSantis takes charge in Florida, promising bipartisanship

The new Republican governor of Florida, Ron DeSantis, will be sworn in on Tuesday after winning a contentious, racially charged election race against Democrat Andrew Gillum. But despite tacking close to Trump during the midterm contest, DeSantis has since picked at least two Democrats for prominent administration positions, apparently sticking to his campaign promise to embrace bipartisanship in the nation’s third most populous state.

Climate change. Unlike his predecessor Rick Scott, DeSantis has also pledged to prioritise environmental issues as governor of a state already experiencing the effects of climate change.

Protesters brand pro-EU MP ‘Nazi’ as Brexit debate simmers

Police in London have been accused of ignoring the verbal harassment of MPs and others by a group of pro-Brexit protesters outside parliament, who loudly accused the pro-EU MP Anna Soubry of being a “Nazi”, and who allegedly racially abused a journalist. The Brexit debate is heating up again this week as MPs prepare to vote on Theresa May’s proposed withdrawal deal. Ireland’s deputy prime minister has said there is no alternative to May’s deal, and British lawmakers who still oppose it must stop “wishful thinking”.

Uncivil War. The Brexit debate was also stoked by the broadcast in the UK on Monday of Brexit: The Uncivil War, a controversial TV drama about the referendum campaign starring Benedict Cumberbatch.

Opinion

For most millennials, the line between life and work is so blurred that it’s barely worth aspiring to a balance, argues Dawn Foster. But burnout is not a generational issue so much as a symptom of capitalism in crisis.

My family at least had sick pay and permanent contracts, even though I’ve apparently risen several social classes above them. For my generation, we’re working harder than ever, for less and less.
