President Donald Trump on Thursday will announce his decision on whether to keep the United States in a global pact to fight climate change, as a source close to the matter said he was preparing to pull out of the Paris accord.
Trump said in a Twitter post on Wednesday night that he would make the announcement at 3 p.m. EDT (1900 GMT) on Thursday in the White House Rose Garden, ending his tweet with “MAKE AMERICA GREAT AGAIN!”
A U.S. withdrawal would deepen a rift with U.S. allies and put the United States in the same league as Syria and Nicaragua as the world’s only non-participants in the landmark 195-nation accord agreed upon in Paris in 2015.
Scientists have said a U.S. withdrawal from the deal could speed up the effects of global climate change, leading to heat waves, floods, droughts, and more frequent violent storms. (Reuters).
Here’s a look at climate change around the world.

A section of a glacier is seen from NASA’s Operation IceBridge research aircraft on March 29, 2017 above Ellesmere Island, Canada. The ice fields of Ellesmere Island are retreating due to warming temperatures. NASA’s Operation IceBridge has been studying how polar ice has evolved over the past nine years and is currently flying a set of eight-hour research flights over ice sheets and the Arctic Ocean to monitor Arctic ice loss aboard a retrofitted 1966 Lockheed P-3 aircraft. According to NASA scientists and the National Snow and Ice Data Center (NSIDC), sea ice in the Arctic appears to have reached its lowest maximum wintertime extent ever recorded on March 7.Scientists have said the Arctic has been one of the regions hardest hit by climate change.

A woman, at right, takes photos of the flooded banks of the Seine river in Paris, June 4, 2016. An international team of scientists has found that man-made climate change nearly doubled the likelihood of last month’s devastating French flooding. In a quick but not peer reviewed analysis, the World Weather Attribution team of climate scientists used past rainfall data and computer simulations to look for global warming’s fingerprints in the heavy downpours in France and Germany.

The sun sets beyond visitors to Liberty Memorial as the temperature hovers around 100 degrees in Kansas City, Mo., July 21, 2016. It’s as if Hillary Clinton and Donald Trump live on two entirely different Earths: one warming, one not. Clinton says climate change “threatens us all,” while Trump tweets that global warming is “mythical” and repeatedly refers to it as a “hoax.” Measurements and scientists say Clinton’s Earth is much closer to reality.

Drivers are stuck in a traffic jam on highway A 1 near to Bad Oldesloe in Germany on July 24, 2016. A new report shows that greenhouse gas emissions in the European Union rose in 2015, the first increase since 2010. The European Environment Agency says emissions grew by 0.5 percent compared with 2014, mainly due to increase from transportation and a colder winter. The report released Thursday, June 1, 2017 comes as the EU is trying to emphasize its commitment to combating climate change. (Markus Scholz/dpa via AP)

A tourist snorkels above coral in the lagoon located on Lady Elliot Island and 80 kilometers north-east from the town of Bundaberg in Queensland, Australia, June 9, 2015. UNESCO World Heritage delegates recently snorkeled on Australia’s Great Barrier Reef, thousands of coral reefs, which stretch over 2,000 km off the northeast coast. Surrounded by manta rays, dolphins and reef sharks, their mission was to check the health of the world’s largest living ecosystem, which brings in billions of dollars a year in tourism. Some coral has been badly damaged and animal species, including dugong and large green turtles, are threatened. UNESCO said the reef’s outlook was “poor”. (David Gray/Reuters)

Smoke streams from the chimneys of the E.ON coal-fired power station in Gelsenkirchen, Germany, and with a capacity of around 2300 MW of power it is one of the most powerful coal-fired power stations in Europe, Nov. 24, 2014. Germany announced on Wednesday, Dec. 3, 2014 a cash boost for measures to cut greenhouse gas emissions, in a bid to meet its ambitious climate target for 2020. Germany has pledged to reduce its carbon dioxide output by 40 percent by the end of the decade, compared to 1990s levels. Current estimates predict it will only achieve a 32-35 percent cut.

This aerial photo of Wednesday, Oct. 31, 2012, shows the New York skyline and harbor. The vast destruction wreaked by the storm surge in New York could have been prevented with a sea barrier of the type that protects major cities in Europe, some scientists and engineers say. The multibillion-dollar price tag of such a project has been a hindrance, but may appear more palatable after the damage from Superstorm Sandy has been tallied. (AP Photo/Mark Lennihan)
