Input: Consider Input: Mondayâs walkout was yet another symbol of how dramatically the U.S. presence at the annual climate summit has changed. In previous years  the government funded an official pavilion to showcase its climate action  among booths from dozens of other countries. The Trump administration declined to sponsor a pavilion this year  so  former New York City Mayor Michael Bloomberg  is footing the bill for the U.S. Climate Action Center  a sprawling series of inflatable domes just outside the main conference area.
Wolfgang Rattay/Reuters The Trump administration declined to sponsor a pavilion to showcase U.S. work on climate action this year  so  former New York City Mayor Michael Bloomberg  is footing the bill for the U.S. Climate Action Center just outside the main conference area.
At a packed launch event Saturday   Bloomberg  said  he  had gathered support for the Paris pact from public officials and leaders who represent some 130 million Americans  and  he  suggested their alternate delegation is just as relevant to the climate talks as the official U.S. negotiating team.
âIf Washington wonât lead  mayors  governors and civil society will â  Bloomberg  said. (âWell  I represent 300-something million Americans â Banks countered in an interview.)

Input: Consider Input: Madrid (AFP) â Real Madrid quietened crisis talk after back-to-back defeats as  Marco Asensio  added to  his  collection of wonder strikes in a 3-0 victory over Las Palmas at the Santiago Bernabeu on Sunday.
A booking would have ruled Casemiro out of the Madrid derby against Atletico in two weeksâ time and he was quickly replaced after  Asensio  secured the three points in stunning fashion.
 Asensio  has made a habit of netting in spectacular fashion in  his  first 18 months at Madrid and pounced on a loose ball 30 yards from goal to rifle a shot that rose all the way on its trajectory into the top corner.
Ronaldo fired inches over twice more  but  whilst his luck remained out in front of goal   he  did provide an enticing cross from which Isco slotted home at the back post for Madridâs third.
