Present Perfect Simple / Present Perfect Continuous Usage In News

 Hi! Today topic is using the perfect tenses, I would like to summarise it with an illustration 

.

I’ve chosen a substantial topic for this and I think everyone should pay attention to this crisis: Climate Change.

At least 85 percent of the global population has experienced weather events made worse by climate change.according to research published Monday in the journal Nature Climate change. ( here we used present perfect because it's a general fact)

These combined findings — which focused on events such as crop failures, floods and heat waves — allowed scientists to make a solid link between escalating extremes and human activities. They concluded that global warming has affected 80 percent of the world’s land area. (here we used for an action happened but affects the present)

Some of the world’s top emitters, including China and India, have yet to formally commit to a new 2030 emissions reduction target. Activists worry that an emerging energy crisis, which has raised prices and triggered (here we use it's finished action touches the present) blackouts, could imperil efforts to get developing economies to phase out polluting fuels. In the United States, climate disasters have already caused ( it focuses the result in the present that's why we use )least 388 deaths and more than $100 billion in damage this year, according to analyses from The Washington Post and the National Oceanic and Atmospheric Administration.

The contrast between the scope of climate disasters and the scale of global ambition is top of mind for hundreds of protesters who have descended on Washington this week to demand an end to fossil fuel use.  ( we used for used for unfinished time events)

The activists, many of them from Indigenous communities that have been harmed by global warming (we used for past recent events without time expression)risked arrest as they remained on the sidewalk outside the White House after police ordered them to clear the area.

The human toll of these events has become impossible to ignore ( we use present perfect because finished action that has effects on present)This summer, hundreds of people in the Pacific Northwest died after unprecedented heat baked the usually temperate region. More than 1 million people in Madagascar are at risk of starvation as a historic drought morphs into a climate-induced famine. Catastrophic flooding caused New Yorkers to drown in their own homes, while flash flooding has inundated refugee camps in South Sudan.( we use for recently passed events)

In a letter released Monday, some 450 organizations representing 45 million health-care workers called attention to the way rising temperatures have increased the risk of many health issues.(we use for general truth )

While members of both parties back a nearly $1 trillion infrastructure bill that has passed ( we use for recently passed events)the Senate and would provide $7.5 billion to build out a national network of electric-vehicle charging stations and several other measures to cut carbon emissions
