Water resources include water contained in oceans and seas.

The statement is - False.

The water resources are referring to the fresh water on our planet, not on all water on the planet. Since the oceans and seas are filled with saline waters, than they are not included into the water resources. The water resources are found in the rivers, streams, freshwater lakes, some of underground waters, because these are containing freshwater that can be used for drinking by the people. Unfortunately, the freshwater is in much smaller amount than all the other types of waters, so we should be very careful and protective of this resource that means life.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
